Ab. No. 70 Efficacy of Perturbation Training on Balance and Function in Older Individuals- An Experimental Study

Introduction: Aging involves decline in visual, vestibular and proprioceptive acuity associated with functional limitations and reduced motor function, disturbing balance and increasing risk of fall. The study evaluates the effect of perturbation training in older individuals with mild to moderate risk of fall and its effect on postural stability and balance. Perturbation training has been advocated as an effective intervention for re-educating proprioception and restoring normal neuromuscular coordination. Older adults can quickly adapt to large postural perturbations, altering their biomechanics and preventing falls. Methods: An experimental trial recruited 30 older individuals (65-85 years) with mild to moderate fall risk through purposive sampling. Participants underwent Perturbation Training with tilt-board and conventional balance exercises thrice weekly for four weeks (12 sessions). Modified-CTSIB test on NeuroCom Balance Master® and Timed Up and Go (TUG) Test were taken at baseline and post-completion. Homogeneity of samples was assessed using Shapiro-Wilk’s Test of Normality. Dependent sample t-tests were employed to analyze group data, with means and standard deviations indicating statistical differences in pre and post outcome measures at 95% confidence interval. Results: Pre and post measures on TUG test and M-CTSIB test on NeuroCom Balance Master® shows statistically significant improvement in TUG values(p<0.0001*) and COG sway velocity in all conditions except on Firm surface with eyes open, with FIEO(p<0.1208), FIEC(p<0.0011*), FOEO(P<0.0013*), FOEC(p<0.0001*) and Composite COG sway velocity(p<0.0001*). Conclusion: Perturbation training coupled with conventional balance exercises, showed to be effective intervention to improve balance and postural control in older individuals. The study lacked follow-up, leaving room for future studies into continuity of exercises and retention of its effects. Implications: Given the effectiveness, the study suggests integrating perturbation training in geriatric rehabilitation protocol to enhance physical function, diminish fear of falling, and boost fall-related self-efficacy.

Early rehabilitation challenges of surgical patients with COVID-19 infection - a single-arm study

Background/Aim. A very limited amount of data regarding the rehabilitation outcome of surgical patients with COVID-19 is available in the current literature. The aim of this study was to point out the characteristics of early rehabilitation of these patients and determine the predictors of rehabilitation outcomes. Methods. The study was designed as a prospective clinical trial. It included patients who had surgical treatment from April 1, 2022, to March 31, 2023, at the University Clinical Center of Vojvodina, Serbia and either had positive results for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preoperatively or developed coronavirus disease 2019 (COVID-19) within 72 hrs after surgery. The rehabilitation program was planned for each patient according to the type of surgical treatment, age, clinical presentation and severity of the COVID-19, length of immobilization, and comorbidities. Rehabilitation treatment (RT) started with a minimum of one 30-minute daily session, up to three 30-minute sessions daily. Patients were assessed at the beginning of RT and discharge. Outcomes were assessed with the Modified Borg Scale (MBS) for dyspnoea, Barthel index (BI) for activities of daily living, Six-Minute Walk Test (6MWT) for exercise tolerance, and Timed up and Go (TUG) test for balance and lower limb mobility. Results. A total of 81 patients were included in the study. RT was successful for 42 patients (24 female and 18 male) with an average age of 62.10 ? 20.07 years. These patients exhibited significant functional improvement, which was measured by all tests that assessed rehabilitation outcome at discharge: BI (p < 0.001), MBS (p < 0.001), 6MWT (p < 0.001), and TUG test (p < 0.001). The remaining 31 patients had unsuccessful RT. The binary logistic regression analysis has shown that age (p = 0.009), cardiovascular disease (p = 0.017), and malignancy (p = 0.022) were significant predictors of rehabilitation outcome. Conclusion. Results of the present study implicate that individually tailored RT during the acute phase of COVID-19 in surgical patients is very challenging. Advanced age, cardiovascular disease, and malignancy are predictors of unfavorable outcomes, and careful consideration is needed when planning the treatment for these patients.

Establishing the Normative Reference Values of Timed Up and Go Test among Normal Weight and Overweight Schoolage Children: A Study Protocol

Introduction: The dynamics of body posture to avoid falling are generally referred to as balance. It has been shown that child developmental skills are influenced by their body compositions. When compared to their peers who are at a healthy weight, children who are overweight or obese frequently show poorer levels of motor proficiency including balance, mobility and related features. Need of the study: The protocol will determine the typical TUG test results in children relative to their body composition, enabling clinicians to effectively screen for balance deficits in children and will enable timely interventions to prevent falls, accidents, and sports injuries in children. Aim: To find the reference values of Timed Up and Go (TUG) test in normal weight and overweight children and compare the values between them. Materials and Methods: A study protocol on school-going children aged 5 to 15 years will be recruited using convenience sampling and divided into two groups based on their Body Mass Index (BMI): normal weight and overweight. The procedure for performing TUG test will be taught to the children, and the time taken for completion will be recorded using a stopwatch. To check the normality, Kolmogorov test will be applied as sample size estimated is above 50. Parametric or non parametric tests will be used for between group analyses.

Impact of a Tailored Self-Management Education Programme for Older Adults with Knee Osteoarthritis in a Multi-Ethnic Country

Self-management education program (SMEP) is essential in the knee osteoarthritis (OA) management. While the benefits of tailored SMEP have been highlighted in the literature, evidence on the effects of tailored knee OA SMEP for multi-ethnic populations, such as in Malaysia, remains limited. Therefore, the aim of this study was to conduct an intervention study on a tailored SMEP among Malaysian older adults with knee OA. Participants aged 60 years and over with a diagnosis of knee OA were recruited. The intervention comprised four weekly structured group SMEP which was developed specifically for the multicultural population in Malaysia. Symptom’s severity and functional performance were assessed at baseline and six-week follow-up using the Knee Injury and Osteoarthritis Outcome Score questionnaire (KOOS), 30 seconds sit to stand (30sST), time up and go (TUG), chair sit and reach (CSR), back stretch (BS), handgrip strength (HGS) and two-minute walk (2MW) tests. Of the 32 individuals recruited, 30 participants, mean age of 66.77 (±6.42) years, completed the post-intervention assessment. Improvements in mean KOOS domains scores were observed by between 1.3% - 8.6% from baseline to follow-up. Significant differences between baseline and follow-up scores were identified for 30sST (p < 0.05), TUG ( p < 0.001) and 2MW (p < 0.001) tests. A 4-week tailored SMEP delivered face to face by a physiotherapist, improved lower limb muscle strength, mobility, balance and endurance. Larger randomized controlled trials regarding the long-term effects of SMEP for older adults with OA is warranted.

Bodyweight Exercise of Lower and Upper Extremities for Female Patients with Rheumatoid Arthritis and the Timed Up-and-Go Test.

At our hospital, orthopedic surgeons and physical and occupational therapists have developed bodyweight exercises for the lower and upper extremities (BELU) for rheumatoid arthritis (RA) patients, including walking [Timed Up-and-Go (TUG) test and figure-of-eight walking) and weight exercises. We aimed to clarify the effect of bodyweight exercise and the Health Assessment Questionnaire (HAQ) cut-off value for a TUG test result of 12 s (or longer) as a risk factor for a fall. All patients underwent BELU twice weekly at home for 6 weeks. We assessed the HAQ score, TUG time, and the strengths of quadriceps femoris, biceps brachii, handgrip, side pinch, and pulp pinch before and after the intervention. We analyzed the data of 42 participants. The mean age was 67.0 ± 12.1 years. The mean Disease Activity Score-28 for rheumatoid arthritis with erythrocyte sedimentation rate was 2.91 ± 0.91. The mean HAQ score was 0.69 ± 0.62. The dominant quadriceps femoris, biceps brachii, pulp pinch, and side pinch strengths were significantly strengthened. TUG time was improved from 9.0 ± 3.0 s to 8.6 ± 3.2 s (P=0.009). The receiver operating characteristic analysis revealed the cut-off value of HAQ for a TUG time of 12 s (or longer) was 1.0 (AUC 0.903, 95% confidence interval 0.792-1.0). Bodyweight exercises strengthened the muscles in female patients with RA, resulting in improved TUG test results. An indicative HAQ cut-off value of 1.0 (or greater) was identified for a TUG test result of 12 s or longer.

Body composition and functional activity in men with heart failure

Aim. To assess the body composition and functional activity (FA) parameters in men with heart failure (HF) of various nature depending on the stage, class and echocardiographic characteristics of the disease.Material and methods. The study included 100 men aged 23-70 years. The main group consisted of 60 men with HF, the control group — 40 men without HF. Quantitative body composition assessment (fat, lean and bone body mass) was carried out using dual-energy X-ray absorptiometry (DXA). Physical activity was assessed using handgrip test, short physical performance battery (SPPB) test, 6-minute walk test (6MWT), and Timed Up and Go (TUG) test.Results. In the HF group, there were a significant decrease in total bone mass, trunk and limb bone mass, total muscle mass, trunk and limbs’ muscle mass, appendicular skeletal muscle index (ASMI), and FA as HF class increased. Fat mass did not differ in individuals with different HF class and stage. HF class was an independent factor in the reduction of total bone mass (b=-301,9, p=0,015), total muscle mass (b=-1903, p=0,03), limb bone mass (b=-147,6, p=0,013) and appendicular muscle mass (AMM) (b=-1903, p=0,001). Total bone mass (b=-2,637, p=0,02) and AMM (b=-3,512, p=0,01) were independently associated with the Vasilenko-Strazhesko HF stage. AMM also had an independent association with left ventricular ejection fraction (LVEF) (b=0,274, p=0,03). The average body composition scores did not differ between the study and control groups, while the scores of handgrip test, 6MWT, SPPB and TUG test were significantly worse in the HF group. NYHA HF class, stage of HF, LVEF, left ventricular end-diastolic volume (LVEDV) and pulmonary artery systolic pressure (PASP) made an independent contribution to FA decrease in men with HF.Conclusion. In patients with HF, there was deterioration in musculoskeletal parameters depending on HF class, stage and LVEF, without significant differences compared to the control group. There was no association of fat mass with the disease, clinical and echocardiographic characteristics. The average parameters of muscle strength and tests of FA were reduced in men with HF compared with the control group and depended on the NYHA class and stage of HF, LVEF, LVEDV, and PASP.

Prediction of Peak Oxygen Consumption in Patients with Heart Disease Based on Performance on the Timed Up and Go Test.

Central Illustration : Prediction of Peak Oxygen Consumption in Patients with Heart Disease Based on Performance on the Timed Up and Go Test CPET: cardiopulmonary exercise test; TUG: timed up and go test; VO2peak: peak oxygen consumption. The use of the timed up and go (TUG) test to assess cardiorespiratory fitness in patients with heart disease has not been well defined in the literature. Test the association between TUG and peak oxygen consumption (VO2peak), construct an equation based on TUG to predict VO2peak, and determine a cutoff point to estimate VO2peak ≥ 20 mL/kg/min. This cross-sectional study included 201 patients with coronary artery disease or heart failure, between 36 and 92 years of age, who underwent TUG and cardiopulmonary exercise test. Correlation, ROC curve, multiple linear regression, and Bland-Altman analyses were performed. The significance level was set at p < 0.05. The mean age of the total sample was 67 ± 13 years, and 70% of participants were male. The mean VO2peak was 17 ± 6 mL/kg/min, and the mean TUG time was 7 ± 2.5 seconds. The correlation between VO2peak and TUG was r = -0.54 (p < 0.001), and R2 was 0.30. The following equation was developed based on TUG: V O 2 peak = 33.553 + ( - 0.149 × age ) + ( - 0.738 × TUG ) + ( - 2.870 × sex ) ; a value of 0 was assigned to the male sex and 1 to the female sex (adjusted R: 0.41; adjusted R2: 0.40). The VO2peak estimated by the equation was 18.81 ± 3.2 mL/kg/min, and the VO2peak determined by cardiopulmonary exercise test was 18.18 ± 5.9 mL/kg/min (p > 0.05). The best cutoff point in the TUG for VO2peak ≥ 20 mL/kg/min was ≤ 5.47 seconds (area under the curve: 0.80; 95% confidence interval: 0.74 to 0.86). TUG and VO2peak showed a significant association. A prediction equation for VO2peak was developed and validated internally with good performance. The cutoff point in the TUG to predict VO2peak ≥ 20 mL/kg/min was ≤ 5.47 seconds.

Dual task impact on functional mobility and interaction of functional level and balance in patients with Duchenne muscular dystrophy

BackgroundDystrophin, a protein crucial for various brain regions governing higher-order functions like learning and memory is notably absent in individuals with Duchenne muscular dystrophy (DMD). This absence of dystrophin in the brain is believed to underlie cognitive challenges in DMD. Cognitive and motor challenges observed in DMD could potentially hinder the execution of dual tasks. Research questionIs there a significant correlation between dual-task performance, functional mobility, and balance in children with DMD? MethodThe study included 28 participants (14 DMD, 14 typical development). Timed Up and Go (TUG) test results were recorded for single and dual-task conditions (motor-motor, cognitive-motor). Functional level was assessed using Motor Function Measurement-32 (MFM-32), Brooke Upper Extremity Scale, and Vignos Scale. Balance was evaluated using Balance Master System and Pediatric Functional Reach Test (PFRT). ResultsSignificant differences in TUG test scores across conditions were observed in both DMD and typical development groups (p < 0.05). Children with DMD exhibited longer completion times compared to typical development children (p < 0.05). Among children with DMD, there was a significant correlation between TUG scores in different task conditions and balance assessment (p < 0.05, r = 0.571 to −0.819). Lower MFM-32 scores in DMD children were correlated with worse TUG performance across conditions (p < 0.05, r = 0.586 to −0.868). SignifianceThis study sheds light on the multifaceted nature of dual-tasking challenges in individuals with DMD, thereby contributing to a deeper understanding of the implications for rehabilitation strategies.

Association between hearing loss and physical performance in patients on maintenance hemodialysis.

The correlation between hearing loss (HL) and physical performance in patients receiving maintenance hemodialysis (MHD) remains poorly investigated. This study explored the association between HL and physical performance in patients on MHD. This multicenter cross-sectional study was conducted between July 2020 and April 2021 in seven hemodialysis centers in Shanghai and Suzhou, China. The hearing assessment was performed using pure-tone average (PTA). Physical performance was assessed using the Timed Up and Go Test (TUGT), handgrip strength, and gait speed. Finally, 838 adult patients (male, 516 [61.6%]; 61.2 ± 2.6 years) were enrolled. Among them, 423 (50.5%) had mild to profound HL (male, 48.6% and female, 53.4%). Patients with HL had poorer physical performance than patients without HL (p < 0.001). TUGT was positively correlated with PTA (r = 0.265, p < 0.001), while handgrip strength and gait speed were negatively correlated with PTA (r = -0.356, p < 0.001 and r = -0.342, p < 0.001, respectively). Physical performance in patients aged <60 years showed significant dose-response relationships with HL. After adjusting for confounders, the odds ratios (95% confidence intervals) for HL across the TUGT quartiles (lowest to highest) were 1.00 (reference), 1.15 (0.73-1.81), 1.69 (1.07-2.70), and 2.87 (1.69-4.88) (p for trend = 0.005). Lower prevalence of HL was associated with a faster TUGT and a stronger handgrip strength in patients on MHD.

Fall status and risk factors in older Chinese adults: A cross-sectional study.

To analyse the risk factors and incidence of falls in geriatric outpatients in a university hospital ward in Hangzhou, China. From May 2020 to August 2022, 1712 geriatric outpatients in a university hospital ward in Hangzhou, China, were screened using a socio-demographic questionnaire (e.g. gender, age, living arrangement, etc.) and assessment scales. The correlation between each factor and falls was preliminarily analysed by chi-squared tests. Finally, binary logistic regression analysis was conducted to further analyse the risk factors of falls. The STROBE checklist was used in reporting this study. Of the 1712 geriatric outpatients recruited, 1626 participants (60-79 and ≥ 80 years old) with complete questionnaire and assessment data were included. The occurrence of falls for those in the 60-79 age group was 8.4%, and for those in the ≥80 age group it was 13.4%. Age (p = .007), use of a walking assistance device (p < .001), the Stay Independent Brochure Questionnaire (SIB) (OR = 7.751, 95% CI = 5.089-11.806, p < .001), living arrangement (p = .004), timed up and go test (TUGT) (p = .007) and three diseases or above (OR = 2.496, 95% CI = 1.358-11.4.586, p = .003) reached statistical significance. Older people have a high incidence of falls. In this study, age, disease history, SIB scores (≥4 points), living arrangement, TUGT and walking assistance device increased the probability of falls in older Chinese adults. Personalised interventions should be carried out according to the specific situation of older people to effectively reduce their incidence of falls and improve their quality of life. The basic characteristics and fall risk factors of the older can help nurses identify fall risk, and early intervention by caregivers can reduce fall-related injuries, which has practical significance for promoting healthy aging. The subjects of this study were older patients ≥60 years old, and the demographic characteristics and fall-related information of patients were obtained by questionnaire. The team worked closely with a team of experts in the field of health care. Some researchers collect data and rewrite them, while other researchers analyse the information and write a paper. All authors read and approved the final manuscript.

The Relationship between Walking Ability and Fall Risk in Poststroke Patients

Objective: To determine the relationship between walking ability and the fall risk in after stroke patients. Method: This research was descriptive quantitative with observational research type. The total sample of 35 people after stroke was obtained using a purposive sampling technique. Measurement of walking ability using the Dynamic Gait Index (DGI) showed a mean ± SD value of walking ability of 16.74 ± 5.20 and measurement of fall risk using the Timed Up and Go Test (TUGT) showed a mean ± SD value of 17.871 ± 6.55. Results: The Pearson Product Moment correlation test obtained a value of p = 0.001with a value of r = - 0.984 which shows a negative correlation between the two variables, which means that when the level of walking ability increases, the fall risk tends to decrease. Conversely, when the level of walking ability decreases, the risk of falling tends to increase. Conclusion: There was a relationship between the ability to walk and the fall risk in after stroke patients. Keywords: Post-stroke patients, walking ability, fall risk, Dynamic Gait Index (DGI), Timed Up and Go Test (TUGT).

The association between disability and physical performance, pain intensity, and pain-related anxiety in patients after lumbar decompression surgery: a cross-sectional study

BackgroundMost patients with lumbar spinal stenosis improve significantly within 6 months of lumbar decompression surgery, however, unfavorable long-term disability may persist in some patients. It was unclear which potential influencing factors were more likely to be associated with disability. This study aimed to assess the association between disability and physical performance, pain, and pain-related anxiety in patients after lumbar decompression surgery.MethodsPatients who underwent decompression for lumbar spinal stenosis were included. Participants completed the visual analog scale, Oswestry Disability Index, and Pain Anxiety Symptoms Scale-20 to collect pain intensity, disability, and pain-related anxiety information. For physical performance assessment, participants performed timed up and go (TUG), functional reach test (FRT), 6-min walking test, and modified Sorensen test, 6–12 months after lumbar decompression surgery. The associations were examined with bivariate and multivariable linear regression analyses.ResultsA total of 80 patients were included. A significant association between disability and pain-related anxiety, the FRT, and the modified Sorensen test scores was confirmed in multivariable analyses. Both bivariate (r = − 0.75) and multivariable (β = 0.60, 95% CI, 0.24, 0.54; P = 0.00) analyses confirmed that pain-related anxiety was the strongest indicator of disability. The association between disability and pain intensity, TUG, and 6-min walking test scores was not confirmed.ConclusionPain-related anxiety should be considered in the rehabilitation programs after lumbar decompression surgery. The evaluation of all aspects of physical performance following lumbar decompression surgery is also recommended.

Rehabilitation of Gate and Balance Disorders in Multiple Sclerosis using Progressive Resistance Power Training: a Randomized Controlled Study

INTRODUCTION. Progressive resistance training (PRT) has been recognized as an effective tool in the rehabilitation of patients with multiple sclerosis (MS), however its comparative efficacy remains has yet to be determined.&#x0D; AIM. In this study, we aimed to evaluate the efficacy and safety of the self-guided in-patient progressive resistance power training (PRT) program for improving gait and balance in patients with MS compared with the standard rehabilitation program.&#x0D; MATERIALS AND METHODS. 60 patients with MS were equally randomized into control group (CG) and the PRT group (PG). Training was performed 5 times/week, for 4 weeks in both groups. The primary endpoint was the percentage of patients with improvement in the 6-minute walking test above a minimal clinically significant difference in both groups. Tests of walking speed and balance (Timed 25-foot walking test (T25FW), Timed up-and-go (TUG) test, walking speed), mean voluntary muscle contraction on dominant and non-dominant legs as well as quality of life tests (cognitive and physical domains) at week 4 were used as secondary endpoints.&#x0D; RESULTS. In PG, 17/27 (63 %) patients reached the primary endpoint compared to 11/23 (48 %) in KG, which did not make a statistically significant difference (p = 0.89). Patients showed significant improvement in the T25FW test and TUG test in PG, but not in CG one. Muscle strength improved in both groups, however patients in PG showed mostly improvement in non-dominant leg and more on knee flexors and feet extensors, while patients in the CG showed improvement in hip flexors on both legs. Quality of life parameters improved in both groups. There were no statistically significant differences between the groups at all the endpoints studied at week 4.&#x0D; DISCUSSION. In both groups, significant increases in distance and walking speed prevented reaching the primary endpoint. PRT has been shown to provide a statistically significant improvement in short-distance walking speed, which may have been due to a positive effect on the rate of force development, increasing walking speed and improving walking balance. The increase in muscle strength occurred in trained muscle groups and had differences between the study groups. This result could be obtained both due to the direct training of certain muscle groups, and due to the phenomenon of contralateral transfer.&#x0D; CONCLUSION. Progressive resistance training may have some beneficial differences compared to non-progressive training that need to be elucidated further.

Physical activity, physical frailty and depressive symptoms among Chinese male and female older adults: do different indicators make a difference?

Older adults become more inactive and frailer with aging. Physical status is closely linked to mental health, but it is unclear which physical indicator is more strongly associated with depressive symptoms in older adults. The present study aimed to compare relationships between self-reported physical activity, physical frailty (muscle mass, muscle strength, and gait ability) and depressive symptoms in community male and female older adults. A total of 1,180 adults aged 60 years and older were recruited to participate in this study from a Chinese community receiving annual check-up service from September 2018 to May 2019. Physical activity was assessed by the International Physical Activity Questionnaire (IPAQ). The Bio-electrical Impedance Analyzer was used to determine the muscle mass. As the indicators of muscle function, grip strength and gait ability were assessed by the dynamometer and Timed Up and Go Test (TUGT), respectively. The 15-item version of Geriatric Depression Scale (GDS-15) was used to examine depressive symptoms. Demographic variables, health status and sleep quality were collected using questionnaire. 11.8% men and 11.9% women reported depressive symptoms. Logistic regression showed that depressive symptoms was associated with low grip strength (OR = 2.42, 95% CI: 1.04-5.63), slow gait ability (OR = 3.60, 95% CI: 1.28-10.13) in older males, and associated with low level of self-reported physical activity (OR = 3.85, 95% CI: 2.00-7.42) in older females. No significant association was found between muscle mass and depressive symptoms. There were gender differences in the relationship between physical activity, physical frailty, and depressive symptoms. Grip strength and gait ability may be a better indicator of frailty for predicting depressive symptoms in older men while physical activity may be useful in predicting depressive symptoms in older women.

Influence of Concurrent Exercise Training on Ankle Muscle Activation during Static and Proactive Postural Control on Older Adults with Sarcopenic Obesity: A Multicenter, Randomized, and Controlled Trial.

Sarcopenic obesity (SO), characterized by age-related muscle loss and excess body fat, significantly impairs postural control. However, limited research has explored the effects of concurrent exercise training on neuromuscular strategies during postural control in older adults with SO. The study enrolled 50 older adults with SO, split into an intervention group (IG, n = 25, mean age = 76.1 ± 3.5 years; mean BMI = 34.4 ± 4.0 kg/m2) and a control group (CG, n = 25, mean age = 75.9 ± 5.4 years; mean BMI = 32.9 ± 2.3 kg/m2). Participants in the IG were engaged in 60-min Total Mobility Plus Program (TMP) sessions three times a week for four months, while the CG maintained their typical daily activities. Standardized evaluations were conducted both before and after the intervention. These assessments included the Romberg and Timed Up and Go (TUG) tests, as well as the measurement of Center of Pressure (CoP) displacements parameters under various conditions. Additionally, ankle muscle activities were quantified during postural control evaluations and maximal voluntary contractions of plantar and dorsal flexors. Post-intervention results revealed a significant reduction of the standing time measured in the Romberg (-15.6%, p < 0.005) and TUG (-34.6%, p < 0.05) tests. Additionally, CoP area and velocity were notably reduced in various conditions (p < 0.05). Postural control improvements were associated with an increase of strength (p < 0.05) and decrease of ankle muscle activation (p < 0.05). These findings highlight the reversibility of neuromuscular system alterations associated with the synergistic effects of sarcopenia and obesity, emphasizing the trainability of postural control regulation within this population. By incorporating these insights into clinical practice and public health strategies, it seems possible to optimize the health and well-being of older adults with SO.

Efficacy of a modified FRAIL scale in predicting the peri-operative outcome of hepatectomy in older adults (aged ≥ 75 years): a model development study

BackgroundThe FRAIL scale for evaluating frailty consists of five items: fatigue, resistance, aerobic, illness, and loss of weight. However, it is difficult to obtain a specific weight loss value. Since the Timed Up and Go Test (TUGT) is simple, accurate, and easy to perform, we replaced weight loss with the TUGT in the FRAIL scale, with the remaining four items unchanged, and named it the FRAIT scale. The aim of this study was to determine the value of the FRAIT scale in predicting the peri-operative outcome of hepatectomy.MethodsThis model development study was conducted between January 2017 and December 2021. The reliability, validity and area under the curve (AUC) of the FRAIL/FRAIT scales were calculated. The frailty status of patients aged ≥ 75 years who underwent hepatectomy was measured using the FRAIL/FRAIT scales. Logistic regression was used to compare the relationship between FRAIL/FRAIT scores/grades and perioperative outcomes.ResultsThe AUCs for predicting operation duration, intraoperative bleeding, complications, and death based on the FRAIL score were 0.692, 0.740, 0.709, and 0.733, respectively, and those based on the FRAIT score were 0.700, 0.745, 0.708, and 0.724, respectively. The AUCs for predicting operation duration, intraoperative bleeding, complications, and death based on the FRAIL grade were 0.693, 0.735, 0.695, and 0.755, respectively, and those based on the FRAIT grades were 0.700, 0.758, 0.699, and 0.750, respectively. The FRAIL score has three effective predictors (intraoperative bleeding, complications, and death), while the FRAIT score has four effective predictors (operation duration, intraoperative bleeding, complications, and death). The FRAIL grade has two effective predictors (intraoperative bleeding and death), while the FRAIT grade has three effective predictors (operation duration, intraoperative bleeding, and death).ConclusionsThis study describes a new and more effective tool for the assessment of preoperative frailty in older adults undergoing hepatectomy. The items of the FRAIT scale are easier to obtain than those of the FRAIL scale, and the predictive effect of the FRAIT scale is stronger than that of the FRAIL scale.

Effect of adding hip exercises to general rehabilitation treatment of knee osteoarthritis on patients’ physical functions: a randomized clinical trial

BackgroundHip adductor and abductor strength were both reduced in KOA patients. But to date, most of the researches have only focused on quadriceps combined with hip abductor strengthening versus quadriceps strengthening.ObjectiveThe aim of the study is to evaluate the effect of adding hip abductor and adductor strengthening to quadriceps strengthening on lower limb strength, knee pain and physical function in patients with medial compartmental knee osteoarthritis.MethodsIn this study, 42 participants, were randomly divided into two groups: the general treatment group (GT group) and the added-hip-exercise group (AH group). All participants were given a general rehabilitation treatment. The AH group performed hip abductor and adductor strengthening in addition to the general rehabilitation treatment. Knee and hip muscle strength, Five Times Sit-to-Stand Test (FTSST), the Timed Up and Go Test (TUGT), Numerical Rating Scale (NRS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were assessed at baseline and 6 weeks. A two-sided 2-sample unpaired t test was performed to compare the difference in mean change scores between AH and GT groups.ResultsFinally, 36 participants completed the study: both groups consist of 18 participants. In the per-protocol analysis, the AH group had a greater improvement in knee extension strength (mean changes, 7.84 versus 36.48; P < 0.001) and hip abduction strength (mean changes, 5.05 versus 26.62; P = 0.001) than the control group. Similarly, the AH group had a greater improvement in the FTSST time (mean changes, 0.40 s versus 3.57 s; P < 0.001) and the TUFT time (mean changes, 0.18 s versus 1.67 s; P = 0.002) than the GH group. No statistical difference was found in the change of WOMAC pain scores and NRS between the 2 groups.ConclusionsOlder adults with knee OA in the AH group had superior muscle strength, symptoms and daily activity performance at the 6th week than those in the GT group. And adding hip exercises could expedite improvement of pain at the 2th week, but not at the 6th week.Trial registrationClinical trial registration numbers and date of registration: ChiCTR-IOR-16009124, Registered 30 August 2016.

Influence of Nutritional Status and Physical Fitness on Cognitive Domains among Older Adults: A Cross-Sectional Study.

The health issues presented by the aging population can result in reduced muscle mass, poorer physical function, and cognitive impairment. The goal of this study was to determine how nutritional status and physical fitness relate to cognitive impairment in older adults. A cross-sectional descriptive and analytical study involving 100 participants was carried out to analyze the impact of nutritional status and physical fitness on cognitive impairment. Nutritional status was assessed with the Eating Assessment Tool (EAT-10) and The Mini Nutritional Assessment-Short Form (MNA-SF); physical fitness via the implementation of manual grip evaluation, the 4-m walking test (4-MWT), and the Timed Up and Go (TUG) test; and cognitive impairment evaluation was conducted using the Mini-Mental State Examination (MMSE), the Boston Naming Test (BNT) and the Controlled Oral Word Association Test (COWAT). Data analysis revealed that higher malnutrition status was associated with fewer correct responses in the COWAT (R2 = 0.421), while a correlation between higher MMSE and BNT scores, faster completion times for the 4-m walking and TUG tests, and an increase in handgrip strength load was also observed. The analysis of the data revealed that those individuals with superior nutritional status and greater levels of physical fitness outperformed others on the cognitive evaluation.
