Impact of Wearable Device-Based Walking Programs on Gait Speed in Older Adults: A Systematic Review and Meta-Analysis.

As walking abilities are widely affected among the aging population, investigating the effectiveness of wearable device-based walking programs is essential. The intentions of this meta-analysis were to investigate their effects on gait speed among older adults, as well as to include subgroup analysis to evaluate potential effects on individuals with aging-related conditions such as Parkinson's disease (PD) and stroke. Systematic retrieval of Pubmed, The Cochrane Library, Embase and Web of Science databases were searched up to February 2024. Outcomes such as gait speed, balance, cadence, and stride length were extracted and analyzed. Study quality was evaluated using the Rob 2 tool and heterogeneity was tested using I2 statistics through STATA 16. Nine studies with 284 participants were analyzed. The intervention group showed a significant improvement in gait speed (weighted mean difference (WMD) 0.12; 95% CI 0.03 to 0.21). There is a subgroup analysis suggesting differential effects: significant improvements in PD and stroke subgroups, but not in the normal aging group. Balance (WMD: 1.93; 95% CI: 0.20 to 3.66) and stride length (WMD: 8.58; 95% CI: 3.04 to 14.12) were also shown to improve, but the heterogeneity across the studies was moderate (I2 = 63.91%). No significant changes were observed in the Timed Up and Go test, Gait Variability, and Step Width. Wearable device-based walking programs improve gait speed in older adults, with top notch advantages in the ones tormented by PD or stroke. These findings advocate that such interventions can be a valuable part of individualized treatment strategies in geriatric care, aiming to enhance mobility and usual satisfactory of existence.

Improvement in Gait Speed Affects Short-term Improvement in Activities of Daily Living in Patients with Moderate and Severe Knee Osteoarthritis.

It is unclear whether improvements in knee pain or physical function lead to improvements in activities of daily living (ADL) and quality of life (QOL) in patients with moderate to severe knee osteoarthritis (KOA). This study aimed to investigate whether improvements in knee pain and physical function, achieved through exercise therapy, lead to improvements in ADL and QOL in patients with moderate to severe KOA. This case-control study included 18 patients with KOA. We evaluated knee range of motion, knee extension muscle strength (KEM), gait speed, knee pain, Knee Injury and Osteoarthritis Outcome Score (KOOS)-ADL, and KOOS-QOL at the first visit and after 3 months of exercise therapy. Patients were classified into the ADL and QOL improvement or no-improvement groups. Statistical analysis used split factorial analysis of variance with time and group as the main effects. When interactions were observed, post-hoc analysis was performed with two-sample t-tests. For ADL improvement, the improvements in KEM of the affected side and gait speed were statistically significant. At 3 months, the gait speed of the improvement group was significantly higher than that of the no-improvement group. For QOL improvement, there was no significant interaction for any of the factors evaluated. No factor showed significant contribution to improved QOL in patients with moderate to severe KOA. However, increased gait speed may improve ADL and contribute to the development of efficient rehabilitation programs for patients with moderate to severe KOA.

Effects of Transcranial Brain Stimulation Combined with Physiotherapy on Lower Limb Motor Recovery in Post-Stroke Patients: a Systematic Review and Meta-analysis.

Introduction: Transcranial stimulation (TS) can integrate motor therapy with satisfactory results in the correction of pathological neural configurations found after stroke. The objective of the study was to synthesize evidence on the effects of TS in post-stroke patients, combined with physiotherapeutic interventions compared with no physiotherapeutic intervention, in improving gait and in reducing spasticity. Methods: Electronic databases PubMed, Embase, Scopus, and Cochrane were searched from 2011 until February 2021. Studies were included if they were randomized clinical trials, that combined TS with physiotherapeutic intervention and were of any nature; the studies included measures related to mobility and muscle tone of the lower limbs and those that approached adults, of legal age, affected by ischemic or hemorrhagic stroke, in the acute, subacute or chronic stage of the disease. We excluded studies that contemplated other neurological diseases; studies aiming only to evaluate efficacy between TS currents and those with samples under ten individuals. Risk of bias assessment of randomized clinical trials was based on the PEDro scale. The meta- analysis was performed according to the random effect model in the R software, comparing the differences between the pre- and post-test of each variable. Results: Five randomized controlled trials (pooled n=133) were included in the meta-analysis. The results of the 10-meters walk test (10MWT) and 6-minute walk test (6MWT) showed a small effect favoring the use of TS combined with physiotherapy in improving gait speed, while the timed up and go test (TUG) and the Functional Ambulation Category (FAC) showed a large effect. The 95% confidence interval (CI) was adopted. Conclusion: TS combined with physical therapy intervention seems to be a useful resource for improving gait performance in post-stroke patients. TS was shown not to be effective in reducing lower limb spasticity. This review is limited by the small number of articles identified in the literature.

A Novel Behavioral Intervention to Enhance Physical Activity for Older Veterans in a Skilled Nursing Facility.

Physical activity levels during skilled nursing facility (SNF) rehabilitation fall far below what is needed for successful community living and to prevent adverse events. This feasibility study's purpose was to evaluate the feasibility, acceptability, and preliminary effectiveness of an intervention designed to improve physical activity in patients admitted to SNFs for short-term rehabilitation. High-Intensity Rehabilitation plus Mobility combined a high-intensity (i.e.,high weight, low repetition), progressive (increasing in difficulty over time), and functional resistance rehabilitation intervention with a behavioral economics-based physical activity program. The behavioral economics component included five mobility sessions/week with structured goal setting, gamification, and loss aversion (the idea that people are more likely to change a behavior in response to a potential loss over a potential gain). SNF physical therapists, occupational therapists, and a mobility coach implemented the High-Intensity Rehabilitation plus Mobility protocol with older Veterans (n = 18) from a single SNF. Participants demonstrated high adherence to the mobility protocol and were highly satisfied with their rehabilitation. Treatment fidelity scores for clinicians were ≥95%. We did not observe a hypothesized 40% improvement in step counts or time spent upright. However, High-Intensity Rehabilitation plus Mobility participants made clinically important improvements in short physical performance battery scores and gait speed from admission to discharge that were qualitatively similar to or slightly higher than historical cohorts from the same SNF that had received usual care or high-intensity rehabilitation alone. These results suggest a structured physical activity program can be feasibly combined with high-intensity rehabilitation for SNF residents following a hospital stay.

COGNITIVE IMPAIRMENT IS ASSOCIATED WITH INFERIOR POSTURAL BALANCE AND REDUCED GAIT SPEED

Abstract Fall-related sequelae including balance as well as gait impairments are more pronounced in older adults with cognitive impairment (CIOA) compared to cognitively healthy older adults (CHOA). Evidence is scarce about differences in postural balance and gait in CHOA and CIOA after a fall, even though these are major risks for recurrent falls. Especially, there is a dearth of data based on validated sensor technologies. Thus, it is our aim to use sensor-based data to investigate differences between these two groups. Postural balance and gait were measured using three wirelessly synchronized IMU’s (APDM, Inc., Portland, USA) in n=50 CHOA, mean age 73.82±8.25 years and n= 56 CIOA, mean age 78.27±8.0 years. Data were collected at participants’ homes as part of a comprehensive geriatric assessment in the “SeFallED” study within four weeks after presentation to the emergency department (ED) after a sentinel fall (German Clinical Trials Register ID: 00025949). Differences in postural balance and gait between two groups were analyzed by using a Mann-Whitney-U-Test. Statistical analysis revealed a significantly poorer postural balance in CIOA compared to CHOA for the parameters Jerk (m2/s5; p=0.039) and mean velocity (m/s; p=0.036). Further, CIOA had a significantly lower gait speed (m/s; p=0.035) and stride length (m/s; p=0.028) compared to CHOA. Even though both groups had shortly experienced a fall with presentation to the ED, impairments in gait and balance parameters were more prominent in CIOA. Based on these results, physical exercise interventions should focus on the improvement of impaired gait speed and balance particularly in CIOA.

Hip-focused physical therapy versus spine-focused physical therapy for older adults with chronic low back pain at risk for mobility decline (MASH): a multicentre, single-masked, randomised controlled trial

Previously, we identified a population of older adults with chronic low back pain, hip pain, and hip muscle weakness who had worse 12-month low back pain and functional outcomes than age-matched adults with only low back pain, indicating an increased risk for future mobility decline. We sought to determine whether tailored, hip-focused physical therapy reduced pain and functional limitations in this high-risk population compared with non-tailored, spine-focused physical therapy. We did a multicentre, single-masked, randomised controlled trial at three research-based sites in the USA. We recruited older adults (aged 60-85 years) with hip pain and weakness who reported moderate low back pain intensity at least half the days in the last 6 months. Patients were randomly assigned to hip-focused physical therapy or spine-focused physical therapy using permuted blocks with random block size, stratified by site and sex (ie, male or female). The primary outcomes were self-reported disability using the Quebec Back Pain Disability Scale (QBPDS) and performance-based 10-Meter Walk Test (10MWT) at 8 weeks. All analyses were done in the intention-to-treat population. Adverse events were collected by study staff via a possible adverse event reporting form and then adjudicated by site investigators. This trial was registered with ClinicalTrials.gov, NCT04009837. Between Nov 1, 2019, and April 30, 2022, 184 participants were randomly assigned to receive hip-focused (n=91) or spine-focused physical therapy (n=93) interventions. The mean age was 70·7 (SD 6·2) years. 121 (66%) of 184 participants were women, 63 (34%) were men, and 149 (81%) were White. At 8 weeks, the mean between-group difference on the QBPDS was 4·0 (95% CI 0·5 to 7·5), favouring hip-focused physical therapy. Both groups had similar, clinically meaningful gait speed improvements (10MWT) at 8 weeks (mean difference 0·004 m/s [95% CI -0·044 to 0·052]). No serious adverse events were related to study participation. Tailored hip-focused physical therapy demonstrated greater improvements in low back pain-related disability at 8 weeks. However, both hip-focused physical therapy and spine-focused physical therapy produced clinically meaningful improvements in disability and function for this high-risk population at 6 months. These findings warrant further investigation before clinical implementation. US National Institute on Aging of the National Institutes of Health.

Personalized Exercise Intervention for Older Adults with Sickle Cell Disease: The Sicklefit Study

Background Older adults with sickle cell disease (SCD) (defined as age ≥ 40 years) experience both SCD and age-related conditions such as recurrent pain episodes, avascular necrosis of the joints, and cardiopulmonary disease that can result in accelerated functional decline. Individuals with SCD experience vaso-occlusive events that lead to reduced oxygen delivery to organs such as bones, muscles, and lungs. Due to these unique risk factors, existing generic exercise programs may be too intense– and even detrimental– for older adults with SCD. Gerofit is a supervised exercise program designed for veterans age ≥ 65 years with chronic disease and/or impaired mobility that has been shown to improve physical function, mental health, quality of life, and survival. The purpose of the study is a pilot evaluation of the feasibility and safety of SickleFit, an exercise training program for older adults with SCD adapted from Gerofit. Methods SickleFit is a group exercise program held on Zoom 3 days a week and includes a safety check in, warm-up, cardio segment, strength training, flexibility, balance, and mindfulness. Our primary endpoint is feasibility measured by proportion of participants attending at least 50% of the sessions over 6 weeks. The secondary outcomes are safety and acceptability. We measured safety as the number of moderate or severe adverse events within 48 hours after each exercise session. Acceptability was measured as the proportion of participants reporting the intervention as satisfactory. Exploratory outcomes were changes in physical performance in a battery of physical assessments including: Usual Gait Speed, 6 Minute Walk Distance (6MWD), Plank duration, Timed Up-and-go (TUG), Seated Grip Strength, Weight, and Neck Circumference. Results Cohort 1 consisted of 2 male (aged 55 and 66 both with SS genotype) and 2 female participants (aged 43 and 53 with Beta + Thalassemia and SS genotype). All 4 participants met the feasibility endpoint of attending at least 50% of exercise sessions, with a mean attendance of 83%. The majority of absences were due to schedule conflicts (2), property maintenance (2), and general malaise (4). Over a third of the missed sessions were due to minor (2) or major (3) adverse events unrelated to the intervention (motor vehicle incident, work-related injury). There were no major or life-threatening adverse events as a result of the exercise intervention. Minor adverse events related to exercise were knee, shoulder, and back soreness and pain. All participants responded as either ‘Pleased’ (50%) or ‘Delighted’ (50%) with the program on the acceptability survey. In addition, all participants saw a positive increase in their performance of the Usual Gait Speed, TUG, 6MWD, and plank duration. Minor improvement in grip strength was seen in 3 participants, but a slight loss in grip strength occurred in one individual whom also lost the most weight. While no significant change occurred in the BMI of the participants, a reduction in neck circumference did occur. Conclusion In cohort 1, we found that the SickleFit exercise program is feasible, acceptable, and safe for older adults with SCD. Participants demonstrated improvements in Usual Gait Speed, TUG, 6MWD, and plank duration, among other physical metrics. Participants expressed satisfaction in the program and a desire to continue in the program, even after the program ended. Based on patient feedback, The Sicklefit program is being optimized further to better meet the needs of older adults with SCD. Optimizations include shortening of the cardio section for the initial weeks of the program, dedicating more time to discussing the biomechanics and form involved in the exercises, integration of more ground-based and vertical pulling patterns with resistance bands, and adding further diversity in the movement practices included in the sessions.

Effectiveness of Virtual Reality and Feedback to Improve Gait and Balance in Patients with Diabetic Peripheral Neuropathies: Systematic Review and Meta-Analysis

Diabetic peripheral neuropathy (DPN) is the primary complication in patients with diabetes mellitus, characterized by loss of sensation and function in the lower limbs. Virtual reality (VR) and/or sensory feedback (FB) therapy has shown positive effects in other neurologic conditions such as stroke. However, consensus regarding their effectiveness in the DPN population is lacking. This study aims to analyze existing scientific evidence about the effects of VR and/or FB on improving gait and balance and reducing the risk of falls in patients with DPN (pwDPN). A thorough search was conducted in scientific databases including PubMed, Scopus, and EMBASE, up until November 2023. CMSQ, the PEDro scale, and the Cochrane Collaboration’s tool were used to assess the methodological quality and risk of bias of the studies. A total of 10 studies were selected for qualitative analysis, with three contributing information to the meta-analysis. The combined results suggest a positive trend in favor of VR and FB rehabilitation; however, significant differences were not observed in balance (SMD = −0.81, 95% CI = −1.90, 0.29; p = 0.15; I2 = 86%) or gait speed improvements (MD = −1.05, 95% CI = −2.96, 0.85; p = 0.28; I2 = 89%). Therefore, further randomized controlled studies are still needed to achieve stronger conclusions regarding the benefits of VR and/or FB in pwDPN.

The FRAGILE clinical trial: the impact of the coronary artery bypass graft in frailty

Abstract Background The exponential increase in the elderly population has been observed worldwide, and it implies a higher incidence of coronary artery disease and, consequently the need for coronary artery bypass graft (CABG). The growing number of elderlies is also related to frailty, a syndrome that affects at least 10% of the elderly population and is an exceedingly effective parameter for correlating with the adverse effects of aging. The impact of frailty concerning mortality and morbidity is well established however, there are no studies regarding the outcomes of CABG and its techniques in frail patients. Purpose To evaluate the impact of coronary artery bypass graft surgery in patient's frailty and compare the differences in the frailty index after a 6-month follow-up between the groups off-pump and on-pump. Methods This was a subanalysis of the FRAGILE trial, a brazilian multicenter, randomized, controlled clinical trial that analyzed 169 patients aged 60 years or older undergoing coronary artery bypass graft surgery with (on-pump) and without (off-pump) cardiopulmonary bypass. Using the Fried's Frailty Criteria, we classifed the patients into frail, pre-frail, and non-frail and also evaluated the five paramenters of this criteria. The patients were divided into two groups: the off-pump CABG group (n=87) and the on-pump CABG group (n=82), and compared unintentional weight loss, self-reported fatigue, physical activity level, grip strength, and gait speed before and after surgery, and between groups. The study was approved by the local Ethics Committee and all patients signed the informed consent. Results We observed an improvement in the frailty of patients undergoing CABG. Overall, over 50% of frail patients became pre-frail after CABG, and only 3% of the total patients were classified as frail after 6 months of surgery (Fig 1A). No patient was classified as non-frail preoperatively in both groups because it was one of the exclusion criteria. There is no difference between the groups off-pump and on-pump (Fig 1B). The total time of physical activity, the gait speed, and the self-reported fatigue were positively impacted regardless of surgical technique. However, grip strength and unintentional weight loss were improved only in the group that underwent off-pump CABG surgery. Patients reported practicing an average more time of exercises, improved gait speed, and claimed to be less fatigated compared to the before-surgery measurements. However, grip strength and unintentional weight loss were improved only in the group that underwent off-pump CABG surgery (Table 1). Conclusion CABG positively impacts patients' frailty after six months of surgery. Both techniques, on-pump and off-pump, showed positive results when comparing frailty features before and after CABG surgery. Nevertheless, the off-pump CABG was the only technique that played a role in improving grip strength and unintentional weight loss of patients after 6 months of surgery.Frailty classificationFrailty's parameters

Effectiveness of a multicomponent rehabilitation protocol on outcomes following post-acute care

BackgroundThe purpose of this study was to determine the effect of a multicomponent rehabilitation protocol on functional outcomes in a post-acute care facility. MethodsEleven older, medically complex patients (80.3 ± 7.3 yrs) completed a multicomponent rehabilitation protocol during a stay at a post-acute care facility. Gait speed, Berg Balance scores, and sit-to-stand velocity were examined upon admission and discharge. Bayesian paired sample t-tests were used to determine changes from PRE to POST and linear regression analyses were used to determine the influence of length of stay. FindingsGait speed increased by 0.26 m/s (49% increase) from PRE (0.65 ± 0.38 m/s) to POST (0.90 ± 0.42 m/s) exercise intervention (p = 0.013). Berg Balance Scores significantly increased by 26% from PRE (38.27 ± 8.33) to POST (45.73 ± 3.32) exercise intervention (p = 0.009). A 45% increase in STS velocity from PRE (0.37 ± 0.14 m/s) to POST (0.51 ± 0.13 m/s; p ≤ 0.001) was observed following the multicomponent rehabilitation protocol. Length of stay did not influence improvements in gait speed, Berg Balance Scores, nor Sit-to-stand velocity (p = 0.176–0.811). InterpretationsThe multicomponent rehabilitation protocol with movement velocity biofeedback is feasible in a post-acute care facility in medically complex older patients and demonstrates improvements in clinical mobility and balance outcomes.

Effectiveness of lower limb rehabilitation protocol using mobile health on quality of life, functional strength, and functional capacity among knee osteoarthritis patients who are overweight and obese: A randomized-controlled trial.

This study aims to investigate the effectiveness of the lower limb rehabilitation protocol (LLRP) using mobile health (mHealth) on quality of life (QoL), functional strength, and functional capacity among knee OA patients who were overweight and obese. Between August 2019 and November 2020, a total of 96 patients (42 males, 54 females; mean age; 52.9±4.8 years; range, 40 to 60 years) were randomized into either the rehabilitation group with mobile health (RGw-mHealth) receiving reminders by using mHealth to carry on the strengthening exercises of LLRP and instructions of daily care (IDC), the rehabilitation group without mobile health (RGwo-mHealth) following the strengthening exercises of LLRP and instructions of daily care (IDC) and control group (CG) only following the IDC for duration of 12 weeks. The reminders for using mHealth were provided two times a day for three days a week. Primary outcome measures were QoL assessed by the Western Ontario and McMaster Universities Osteoarthritis Index summary score, and functional strength by five-repetition sit-to-stand test. Secondary outcome measure was functional capacity assessed by the Gait Speed Test. The assessments of QoL, functional strength, and functional capacity were taken at baseline and post-test after 12 weeks of intervention. After 12 weeks of intervention, the patients in all three groups had a statistically significant improvement in QoL within groups (p<0.05). Patients in the RGw-mHealth and RGwo-mHealth had a statistically significant improvement in functional strength and walking gait speed within groups (p<0.05). The pairwise between-group comparisons (Bonferroni post-hoc test) of the mean changes in QoL, functional strength, and functional capacity at post-test assessments revealed that patients in the RGw-mHealth had a statistically significant greater mean change in QoL, functional strength and functional capacity relative to both the RGwo-mHealth and CG (p<0.001). The improvement in QoL, functional strength, and functional capacity was greater among patients in the RGw-mHealth compared to the RGwo-mHealth or CG.

Mobility Rehab visual feedback system for gait rehabilitation in older adults

BackgroundGait and balance impairments are among the main causes of falls in older adults. The feasibility and effectiveness of adding sensor-based feedback to physical therapy (PT) in an outpatient PT setting is unknown. We evaluated the feasibility and effectiveness of PT intervention combined with a therapist-assisted visual feedback system, called Mobility Rehab, (PT + MR) in older adults.MethodsTwenty-eight older adults with and without neurological diseases were assigned either PT + MR (n = 22) or PT alone (n = 6). Both groups performed 8 sessions (individualized) of 45 min long (30 min for gait training and 15 min for endurance, strength, and balance exercises) in an outpatient clinic. Mobility Rehab uses unobtrusive, inertial sensors on both wrists and feet, and at the sternum level with real-time algorithms to provide real-time feedback on five gait metrics (step duration, stride length, elevation at mid-swing, arm swing range-of-motion [ROM], and trunk coronal ROM), which are displayed on a tablet. The primary outcome was the Activities-specific Balance Confidence scale (ABC). The secondary outcome was gait speed measured with wearable inertial sensors during 2 min of walking.ResultsThere were no between-group differences at baseline for any variable (P > 0.05). Neither PT + MR nor PT alone showed significant changes on the ABC scores. PT + MR, but not PT alone, showed significant improvements in gait speed and arm swing ROM. The system was evaluated as ‘easy to use’ by the PT.ConclusionsOur preliminary results show that PT + MR improves gait speed in older adults with and without neurological diseases in an outpatient clinic.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier: NCT03869879.

Tango-therapy vs physical exercise in older people with dementia; a randomized controlled trial

BackgroundDementia is a growing health concern that affects millions of people worldwide. Gait and mobility disorders are often present and represent a major risk factor for falls. The purpose of this study was to investigate the effectiveness of tango-therapy in gait speed, functional mobility, balance, falls, ability to perform activities of daily living and quality of life.MethodsA randomised controlled trial with 31 participants living in a specialised dementia unit, aged 65 to 93 years old, who were randomly assigned to tango group (IG) or physical exercise group (CG). The primary outcome was gait speed and Timed Up and Go test. The secondary outcomes include the Short Physical Performance Battery, the ability to perform activities of daily living (Katz Index) and quality of life (Quality of life in Alzheimer Disease). Measurements were performed at baseline, and after one and three months of training.ResultsAfter 3 months, IG improved gait speed (p = 0.016), implying a statistically significant difference between groups in favour of IG (p = 0.003). CG significantly worsened the time to complete the TUG (p = 0.039). Both groups declined in their ability to perform activities of daily living, being statistically significant only in the CG (p < 0.001).ConclusionTango interventions showed efficacy in improving gait speed and in mitigating the decline in functional mobility and ADL skill capacities. Allowing older people with dementia access to non-pharmacological interventions may be a successful strategy to prevent functional decline.Trial registrationRegistered at ClinicalTrials.gov (ID: NCT05744011).

Enhanced Gait Recovery in Chronic Post-COVID-19 Stroke: The Role of Combined Physical Rehabilitation

Background: Rehabilitation programs applied in cases of COVID-19-related stroke should counteract not only the effects of the stroke but also the effects of long-term COVID-19. As the molecular processes underlying these cases are still not fully understood, and evidence-based clinical outcomes are scarcely documented, there is a valid need to gather information and develop rehabilitation strategies for these patients. The risks, already clarified in the case of stroke, need to be assessed taking into account the coincidence of the two diseases. Endothelial injuries and emboli that develop after the hypercoagulable state of COVID-19 may take longer to heal, and complications may occur during exercise. This case study attempts to determine what the rehabilitation of a COVID-19-related stroke patient should include. The participant was a 64-year-old male with ischemic right middle cerebral artery stroke, left-side hemiplegia, and middle cerebral artery stenosis, and the CT showed a well-defined area of hypoattenuation in the basal ganglia territory involving the right lentiform nucleus, the anterior and posterior limbs of the internal capsule, and the dorsal part of the external capsule. His NIHSS score was 14, and he registered 15 points on the Barthel index. The patient had a COVID-19 infection two weeks before the stroke event. Methods: Conventional physical therapy was combined with adaptive ballistic strength training, a high-intensity interval training regimen, and manual treatment for myofascial release throughout the chronic recovery phase. Our primary goals were gait rehabilitation, muscle strengthening, weakness management, as well as spasticity reduction, while three different rehabilitation approaches were adopted in a single rehabilitation program to improve the outcome and long-term functional recovery of the patient. Results: The patient progressed in almost every aspect of the assessment criteria. This combined approach’s main success was improved gait speed, gait quality, and improved cardiovascular fitness. Take-away message: In the case of a stroke caused by COVID-19, where the endothelium cells are compromised, HIIT may be questionable due to the poor vascular condition. Based on our results, the low-volume HIIT approach proved appropriate and effective.

Dietary behaviour change intervention for managing sarcopenic obesity among community-dwelling older people: a pilot randomised controlled trial

BackgroundThe effects of dietary intervention in managing sarcopenic obesity are controversial, and behavior change techniques are lacking in previous studies which are important for the success of dietary intervention. This study aimed to evaluate the feasibility and preliminary effects of a dietary behaviour change (DBC) intervention on managing sarcopenic obesity among community-dwelling older people in the community.MethodsA two-armed, RCT was conducted. Sixty community-dwelling older adults (≥ 60 years old) with sarcopenic obesity were randomised into either the experimental group (n = 30), receiving a 15-week dietary intervention combined with behaviour change techniques guided by the Health Action Process Approach model, or the control group (n = 30), receiving regular health talks. Individual semi-structured interviews were conducted with 21 experimental group participants to determine the barriers and facilitators of dietary behaviour changes after the intervention.ResultsThe feasibility of the DBC intervention was confirmed by an acceptable recruitment rate (57.14%) and a good retention rate (83.33%). Compared with the control group, the experimental group significantly reduced their body weight (p = 0.027, d = 1.22) and improved their dietary quality (p < 0.001, d = 1.31). A positive improvement in handgrip strength (from 15.37 ± 1.08 kg to 18.21 ± 1.68 kg), waist circumference (from 99.28 ± 1.32 cm to 98.42 ± 1.39 cm), and gait speed (from 0.91 ± 0.02 m/s to 0.99 ± 0.03 m/s) was observed only in the experimental group. However, the skeletal muscle mass index in the experimental group decreased. The interview indicated that behaviour change techniques enhanced the partcipants’ compliance with their dietary regimen, while cultural contextual factors (e.g., family dining style) led to some barriers.ConclusionThe DBC intervention could reduce body weight, and has positive trends in managing handgrip strength, gait speed, and waist circumference. Interestingly, the subtle difference between the two groups in the change of muscle mass index warrants futures investigation. This study demonstrated the potential for employing dietary behaviour change interventions in community healthcare.Trial registrationRegistered retrospectively on ClinicalTrailas.gov (31/12/2020, NCT04690985).

Exploring Potential Predictors of Treadmill Training Effects in People With Parkinson Disease

ObjectiveTo explore the potential predictors of people with Parkinson disease (PD) who would benefit the most from treadmill training. DesignA cohort study. SettingMedical university rehabilitation settings. ParticipantsSeventy participants diagnosed of idiopathic PD. InterventionsTwelve sessions of treadmill training. Main Outcome MeasuresHierarchical logistic regression models were used to explore significant predictors of the treadmill training effect with respect to 3 health domains: Unified Parkinson's Disease Rating Scales part III (UPDRS III); gait speed; Parkinson's Disease Questionnaire-39 (PDQ-39). A receiver operating characteristic (ROC) curve analysis was conducted to identify proper cut-off points for clinical use. ResultsMale sex (adjusted odds ratio [OR]: 3.73, P=.036) significantly predicted the improvement of UPDRS III. Individuals with a slower baseline gait speed (cut-off: 0.92 m/s, adjusted OR: 14.06, P<.001) and higher baseline balance confidence measured by the Activity-specific Balance Confidence scale (cut-off: 84.5 points, adjusted OR: 4.66, P=.022) have greater potential to achieve clinically relevant improvements in gait speed. A poorer baseline PDQ-39 score (cut-off: 23.1, adjusted OR: 7.47, P<.001) predicted a greater quality of life improvement after treadmill training. ConclusionsThese findings provide a guideline for clinicians to easily identify suitable candidates for treadmill training. Generalization to more advanced patients with PD warrants further investigation.

Subjective Cognitive Decline and Frailty Trajectories and Influencing Factors in Japanese Community-Dwelling Older Adults: A Longitudinal Study.

We studied frailty and subjective cognitive decline (SCD) trajectories in older Japanese adults and evaluated the influence of various factors on these trajectories. We analyzed data from 1157 non-demented adults aged 70 and above from 2013 to 2019. Frailty was assessed using the self-administered Kihon Checklist (KCL), a Japanese frailty index. SCD was evaluated using the questionnaire of the Subjective Memory Complaints scale. Through group-based joint trajectory models, we discerned three frailty trajectories: non-progressive (n = 775), moderate progressive (n = 312), and rapid progressive (n = 70); and three SCD trajectories: non-progressive (n = 302), moderate progressive (n = 625), and rapid progressive (n = 230). Individuals in the rapid progressive SCD trajectory had a 32.2% probability of also being in the rapid progressive frailty trajectory. In contrast, those in the non-progressive SCD trajectory had zero probability of being in the rapid progressive frailty trajectory. Both the rapid progressive frailty and SCD groups combined had a higher incidence of depressive symptoms and slow gait speed. Our results have found that frailty and SCD share a similar trajectory in Japanese older adults. Additionally, rapid progressive frailty and SCD were associated with the highest risk of depressive symptoms and slow gait speed. Thus, interventions targeting both frailty and cognitive decline should prioritize mental health enhancement and gait speed improvement.

Game-based intradialytic non-weight-bearing exercise training on gait speed and balance in older adults with diabetes: a single-blind randomized controlled trial

Older adults with diabetes receiving hemodialysis have impaired gait speed and balance compared to the general population, which have been associated with increased risks of falls and mortality. This study evaluated the effectiveness of a game-based intradialytic exercise training program (iExergame) on improving gait speed and balance. This was a single-blind randomized controlled trial. The intervention group (IG) received iExergame training using real-time audiovisual feedback with wearable inertial sensors. The control group (CG) received conventional training without any technology. Both trainings were intradialytic, non-weight-bearing, and used ankle range of motion. Gait and balance parameters were collected at baseline and 4-week follow-up. Data from 70 adults (age 64.2 ± 9.0 years) were analyzed. Compared to the CG, the IG showed greater changes between baseline and 4-week follow-up in several parameters. Gait parameters included faster speeds and longer stride lengths, particularly during dual task walking (p < 0.050). Balance parameters included reductions in center of mass (p = 0.004), ankle (p < 0.001), and hip (p = 0.010) sways during semi-tandem stance, particularly in users of assistive devices. iExergame training could improve gait speed and balance in this population and might be an option to increase intradialytic exercise adherence while reducing burdens of exercise administration.

A Novel Approach for Improving Gait Speed Estimation Using a Single Inertial Measurement Unit Embedded in a Smartphone: Validity and Reliability Study.

Gait speed is a valuable biomarker for mobility and overall health assessment. Existing methods to measure gait speed require expensive equipment or personnel assistance, limiting their use in unsupervised, daily-life conditions. The availability of smartphones equipped with a single inertial measurement unit (IMU) presents a viable and convenient method for measuring gait speed outside of laboratory and clinical settings. Previous works have used the inverted pendulum model to estimate gait speed using a non-smartphone-based IMU attached to the trunk. However, it is unclear whether and how this approach can estimate gait speed using the IMU embedded in a smartphone while being carried in a pants pocket during walking, especially under various walking conditions. This study aimed to validate and test the reliability of a smartphone IMU-based gait speed measurement placed in the user's front pants pocket in both healthy young and older adults while walking quietly (ie, normal walking) and walking while conducting a cognitive task (ie, dual-task walking). A custom-developed smartphone application (app) was used to record gait data from 12 young adults and 12 older adults during normal and dual-task walking. The validity and reliability of gait speed and step length estimations from the smartphone were compared with the gold standard GAITRite mat. A coefficient-based adjustment based upon a coefficient relative to the original estimation of step length was applied to improve the accuracy of gait speed estimation. The magnitude of error (ie, bias and limits of agreement) between the gait data from the smartphone and the GAITRite mat was calculated for each stride. The Passing-Bablok orthogonal regression model was used to provide agreement (ie, slopes and intercepts) between the smartphone and the GAITRite mat. The gait speed measured by the smartphone was valid when compared to the GAITRite mat. The original limits of agreement were 0.50 m/s (an ideal value of 0 m/s), and the orthogonal regression analysis indicated a slope of 1.68 (an ideal value of 1) and an intercept of -0.70 (an ideal value of 0). After adjustment, the accuracy of the smartphone-derived gait speed estimation improved, with limits of agreement reduced to 0.34 m/s. The adjusted slope improved to 1.00, with an intercept of 0.03. The test-retest reliability of smartphone-derived gait speed was good to excellent within supervised laboratory settings and unsupervised home conditions. The adjustment coefficients were applicable to a wide range of step lengths and gait speeds. The inverted pendulum approach is a valid and reliable method for estimating gait speed from a smartphone IMU placed in the pockets of younger and older adults. Adjusting step length by a coefficient derived from the original estimation of step length successfully removed bias and improved the accuracy of gait speed estimation. This novel method has potential applications in various settings and populations, though fine-tuning may be necessary for specific data sets.

Preoperative Lower-Limb Muscle Predictors for Gait Speed Improvement after Total Hip Arthroplasty for Patients with Osteoarthritis.

This study aimed to identify preoperative lower-limb muscle predictors for gait speed improvement after total hip arthroplasty (THA) with hip osteoarthritis. Gait speed improvement was evaluated as the subtraction of preoperative speed from postoperative speed. The preoperative muscle composition of ipsilateral hip abductors was evaluated using computed tomography. The females (n = 45) showed smaller total cross-sectional areas of the gluteal muscles than the males (n = 13). The gluteus maximus in the females showed lower lean muscle mass area (LMM) and higher ratios of the intramuscular fat area and the intramuscular adipose tissue area to the total muscle area (TM) than the males. Regression analysis revealed that LMM/TM of the glutei medius and minimus may correlate negatively with postoperative improvement in gait speed. Receiver operating characteristic curve analysis for prediction of minimum clinically important improvement in gait speed at ≥0.32 m/s resulted in the highest area under the curve for TM in the upper portion of the gluteus maximus with negative correlation. The explanatory variables of hip abductor muscle composition predicted gait speed improvement after THA more precisely in the females compared with the total group of both sexes. Preoperative muscle composition should be evaluated separately based on sex for the achievement of clinically important improvement in gait speed after THA.
