Sensor-Based Gait and Balance Assessment in Healthy Adults: Analysis of Short-Term Training and Sensor Placement Effects.

While the analysis of gait and balance can be an important indicator of age- or disease-related changes, it remains unclear if repeated performance of gait and balance tests in healthy adults leads to habituation effects, if short-term gait and balance training can improve gait and balance performance, and whether the placement of wearable sensors influences the measurement accuracy. Healthy adults were assessed before and after performing weekly gait and balance tests over three weeks by using a force plate, motion capturing system and smartphone. The intervention group (n = 25) additionally received a home-based gait and balance training plan. Another sample of healthy adults (n = 32) was assessed once to analyze the impact of sensor placement (lower back vs. lower abdomen) on gait and balance analysis. Both the control and intervention group exhibited improvements in gait/stance. However, the trends over time were similar for both groups, suggesting that targeted training and repeated task performance equally contributed to the improvement of the measured variables. Since no significant differences were found in sensor placement, we suggest that a smartphone used as a wearable sensor could be worn both on the lower abdomen and the lower back in gait and balance analyses.

Process evaluation protocol plan for a home-based physical activity intervention versus educational intervention for persistent taxane-induced peripheral neuropathy (B-HAPI study): a randomized controlled trial

BackgroundEvaluation publications typically summarize the results of studies to demonstrate the effectiveness of an intervention, but little is shared concerning any changes implemented during the study. We present a process evaluation protocol of a home-based gait, balance, and resistance exercise intervention to ameliorate persistent taxane-induced neuropathy study according to 7 key elements of process evaluation.MethodsThe process evaluation is conducted parallel to the longitudinal, randomized control clinical trial examining the effects of the home-based gait, balance, and resistance exercise program for women with persistent peripheral neuropathy following treatment with taxanes for breast cancer (IRB approval: Pro00040035). The flowcharts clarify how the intervention should be implemented in comparable settings, fidelity procedures help to ensure the participants are comfortable and identify their individual needs, and the process evaluation allows for the individual attention tailoring and focus of the research to avoid protocol deviation.ConclusionsThe publication of the evaluation protocol plan adds transparency to the findings of clinical trials and favors process replication in future studies. The process evaluation enables the team to systematically register information and procedures applied during recruitment and factors that impact the implementation of the intervention, thereby allowing proactive approaches to prevent deviations from the protocol. When tracking an intervention continuously, positive or negative intervention effects are revealed early on in the study, giving valuable insight into inconsistent results. Furthermore, a process evaluation adds a participant-centered element to the research protocols, which allows a patient-centered approach to be applied to data collection.Trial registrationClinicalTrials.gov NCT04621721, November 9, 2020, registered prospectively.

The Impact of Multimorbidity Patterns on Changes in Physical Activity and Physical Capacity Among Older Adults Participating in a Year-Long Exercise Intervention.

This study investigated the impact of multimorbidity patterns on physical activity and capacity outcomes over the course of a year-long exercise intervention, and on physical activity 1year later. Participants were 314 physically inactive community-dwelling men and women aged 70-85years, with no contraindications for exercise at baseline. Physical activity was self-reported. Physical capacity measurements included five-time chair-stand time, 6-minute walking distance, and maximal isometric knee-extension strength. The intervention included supervised and home-based strength, balance, and walking exercises. Multimorbidity patterns comprised physician-diagnosed chronic disease conditions as a predictor cluster and body mass index as a measure of obesity. Multimorbidity patterns explained 0%-12% of baseline variance and 0%-3% of the change in outcomes. The magnitude and direction of the impact of unique conditions varied by outcome, time point, and sex. Multimorbid older adults with no contraindications for exercise may benefit from multimodal physical training.

How Perceptions of Aging Influence Physical Activity and Exercise in Older Age: Exploring the Behavior of People Aged 70+ Years Engaged in Fall Prevention Activities.

For older people, physical inactivity increases fall risk as well as other preventable health conditions. Despite the well-documented benefits of physical activity, uptake and adherence continue to challenge efforts aimed at increasing physical activity and reducing falls. Nested within a randomized controlled trial, this study reports on the factors influencing the physical activity behavior of people, aged between 70 and 90years, engaged in StandingTall, a home-based balance exercise program proven to reduce falls in the community. The perception of aging, physical activity in older age, and the delivery of exercise were identified as major themes, with the perception of aging an overarching theme influencing both preferences for physical activity in older age and exercise delivery. Findings demonstrate the importance of considering the role of aging, the influence aging has on physical activity and exercise behavior, and how aging influences the delivery and design of exercise programs including falls prevention activities for older people.

A systematic review of exergame usability as home-based balance training tool for older adults usability of exergames as home-based balance training.

Exergames are a fun, viable, attractive, and safe way to engage in physical exercise for most patient populations, including older adults. Their use in the home environment enables an expanded understanding about its applicability and its impact on clinical outcomes that can contribute to improved functionality and quality of life in this population. This systematic review aimed to synthesize the evidence on the usability of exergames as a tool for home-based balance training in older adults. The search was realized in 6 electronic databases and were included 1) randomized controlled trials with exergames home-based training as intervention, 2) studies involving older adults (aged 60 years or older) described as having impaired static or dynamic balance, 3) that compared the effects of exergames to usual care, health education or no intervention, and 4) reported usability and balance outcomes. The Cochrane Risk of Bias tool for randomized trials version 2 and the Grading of Recommendations Assessment, Development, and Evaluation were used to evaluate the methodological quality of studies and levels of evidence for outcomes. After screening 1107 records, we identified 4 trials were included. The usability score of exergames was classified as an acceptable, good, and feasible tool. The pooled effect indicated improvements in favor of the exergame group for functional balance by TUG test (MD = -5.90; 95%CI = -10.29 to -1.51) with low-certainty evidence and Tinetti scale (MD = 4.80; 95%CI = 3.36 to 6.24) with very low-certainty evidence. Analyzing the different immersion level, it was observed a significant difference in the experimental group for the immersive exergames (MD = -9.14; 95%CI = -15.51 to -2.77) with very low-certainty evidence. Exergames applied at home showed good usability and had significant effects on functional balance compared to usual care or no intervention, especially in the immersive modality.

Responsiveness of Patient-Reported and Device-Based Physical Activity Measures: Secondary Analysis of Four Randomized Trials.

This study aimed to compare the responsiveness of patient-reported and device-based instruments within four physical activity trials. This was a secondary analysis of four randomized trials that used both a patient-reported outcome measure (the Incidental and Planned Exercise Questionnaire (IPEQ)) and a device-based instrument (ActiGraph or ActivPAL) to measure physical activity. The four trials included were (i) Activity and MObility UsiNg Technology (AMOUNT), digitally enabled exercises in those undertaking aged care and neurological rehabilitation; (ii) Balance Exercise Strength Training at Home, home-based balance and strength exercises in community-dwelling people 65 yr or older; (iii) Coaching for Healthy Ageing (CHAnGE), physical activity coaching and fall prevention intervention in community-dwelling people 60 yr or older; and (iv) Fitbit trial, fall prevention and physical activity promotion with health coaching and activity monitor in community-dwelling people 60 yr or older. We estimated treatment effects for all variables within each physical activity instrument using regression analyses and expressed results as effect sizes (ES). Overall, device-based instruments were more responsive among healthy older adults (ES range, 0.01 to 0.32), whereas the IPEQ was more responsive among adults requiring rehabilitation (ES range, -0.06 to 0.35). Both the IPEQ and device-based instruments were more responsive in trials that promoted walking via coaching participants to increase their daily steps (AMOUNT (ES range, -0.06 to 0.35), CHAnGE (ES range, -0.24 to 0.22), and Fitbit trial (ES range, -0.23 to 0.32)). Individual variables within the IPEQ and device-based instruments varied in their responsiveness (ES range, -0.13 to 0.20). Both the IPEQ and device-based instruments are able to detect small changes in physical activity levels. However, responsiveness varies across different interventions and populations. Our findings provide guidance for researchers and clinicians in selecting an appropriate instrument to measure changes in physical activity.

Balance telerehabilitation and wearable technology for people with Parkinson’s disease (TelePD trial)

BackgroundBalance impairments, that lead to falls, are one of the main symptoms of Parkinson’s disease (PD). Telerehabilitation is becoming more common for people with PD; however, balance is particularly challenging to assess and treat virtually. The feasibility and efficacy of virtual assessment and virtual treatment of balance in people with PD are unknown. The present study protocol has three aims: I) to determine if a virtual balance and gait assessment (instrumented L-shape mobility test) with wearable sensors can predict a gold-standard, in-person clinical assessment of balance, the Mini Balance Evaluation Systems Test (Mini-BESTest); II) to explore the effects of 12 sessions of balance telerehabilitation and unsupervised home exercises on balance, gait, executive function, and clinical scales; and III) to explore if improvements after balance telerehabilitation transfer to daily-life mobility, as measured by instrumented socks with inertial sensors worn for 7 days.MethodsThe TelePD Trial is a prospective, single-center, parallel-group, single-blind, pilot, randomized, controlled trial. This trial will enroll 80 eligible people with PD. Participants will be randomized at a 1:1 ratio into receiving home-based balance exercises in either: 1) balance telerehabilitation (experimental group, n = 40) or 2) unsupervised exercises (control group, n = 40). Both groups will perform 12 sessions of exercise at home that are 60 min long. The primary outcome will be Mini-BESTest. The secondary outcomes will be upper and lower body gait metrics from a prescribed task (instrumented L-shape mobility test); daily-life mobility measures over 7 days with wearable sensors in socks, instrumented executive function tests, and clinical scales. Baseline testing and 7 days of daily-life mobility measurement will occur before and after the intervention period.ConclusionThe TelePD Trial will be the first to explore the usefulness of using wearable sensor-based measures of balance and gait remotely to assess balance, the feasibility and efficacy of balance telerehabilitation in people with PD, and the translation of balance improvements after telerehabilitation to daily-life mobility. These results will help to develop a more effective home-based balance telerehabilitation and virtual assessment that can be used remotely in people with balance impairments.Trial registrationThis trial was prospectively registered on ClinicalTrials.gov (NCT05680597).

Evidence of lateralised white matter plasticity: A longitudinal study of balance performance in nonexpert healthy adults.

Training-induced plasticity by practicing expert skills has been of particular interest; however, little is known about white matter plasticity for improving a fundamental element of body function, such as balance or postural control. This study explored white matter plasticity in nonexpert healthy adults, based on stepwise balance training. Seventeen participants were included and performed a home-based balance training program for 4weeks (30 min/day, 3days/week). Before commencing training, they underwent a baseline diffusion tensor imaging scan. A second scan was acquired at the end of the 4-week training. Lateralised balance load was applied on the right leg to contrast any lateralised effect on the white matter tracts. The balance function was assessed using the Community Balance & Mobility Scale. We examined changes in the fractional anisotropy values of the tracts of interest between pre- and post-training. After the 4-week training, the fractional anisotropy values were enhanced in the right superior cerebellar peduncle, transverse pontine fibre, body of the corpus callosum, left fornix and left uncinate fasciculus. The Community Balance & Mobility Scalescore improved after 4-week training, but an association with changes in fractional anisotropy values cannot be evaluated due to the ceiling effect of the balance assessment tools. Balance training can strengthen the cerebro-cerebellar and interhemispheric structural connections and induce microstructural changes in the limbic structures, including the fornix and uncinate fasciculus. The effect of a lateralised balance load could be projected to the specific white matter tracts in a lateralised manner.

Effects of Home-Based Boxing Training on Trunk Performance, Balance, and Enjoyment of Patients With Chronic Stroke.

To investigate the effect of 6 weeks of home-based boxing training on trunk performance, balance, fear of falling, and level of therapy enjoyment in individuals with chronic stroke. Eighteen participants with chronic stroke were randomly divided into boxing and control groups (9 patients per group). The boxing group received home-based boxing training for 25 minutes plus balance and trunk exercise training for 15 minutes, while the control group received only home-based balance and trunk exercise training for 40 minutes, three days a week for 6 weeks. The Trunk Impairment Scale (TIS), Mini-Balance Evaluation Systems Test (Mini-BESTest), Activities-specific Balance Confidence (ABC) scale, and Physical Activity Enjoyment Scale (PACES) were assessed at baseline, and at 2, 4, and 6 weeks post-training. The Wilcoxon signed rank test and Mann-Whitney U-test were used to determine differences between pre- and post-training within and between groups. Statistical significance was set at p<0.05. The TIS scores significantly increased from 13 to 17 points in the boxing group (p<0.05) compared to an increase from 15 to 17 points in the control group (p<0.05). The Mini-BESTest scores significantly increased from 14 to 22 points in the boxing group (p<0.05) compared to an increase from 17 to 20 points in the control group (p<0.05). There were no differences in the TIS, Mini-BESTest, ABC, and PACES scores between the two groups. Home-based boxing training with balance and trunk exercise training had a similar training effect compared to home-based balance and trunk exercise training.

Caring for Informal Dementia Caregivers and Their Loved Ones Via the HOMeCARE Exercise and Mindfulness for Health Program (HOMeCARE): A Randomized, Single-Blind, Controlled Trial.

Objective: To investigate the effects of a dyadic intervention of mindfulness-based stress reduction (MBSR) for informal dementia caregivers and home-based balance and progressive resistance training (PRT) for their loved ones. Methods: The study was a two arm, randomized, controlled, single-blinded, parallel-group trial. Dyads were randomized to an intervention group: an 8-week MBSR course (daily) and an 8-week PRT and balance training (3 days/week) for their loved ones or a waiting list control group. Results: Nine dyads were randomized [caregivers: median age 75 (40-81) years, loved ones: 77 (73-88) years]. The intervention significantly improved caregiver mindfulness [relative effect size (95% confidence interval) 1.35 (-0.10, 2.81); p = .009] and functional mobility in their loved ones [mean difference (95% confidence interval) 1.53 (-3.09, 6.14)] with no significant effects on caregiver burden [relative effect size (95% confidence interval) 0.22 (-1.09, 1.54); p = .622]. Conclusion: The study appeared feasible in the home environment and future large and longer trials should test the efficacy of a more abbreviated MBSR intervention and to optimize adoption and sustain adherence over time.

Best-Practice Exercise Interventions to Prevent Falls in Older Adults

Globally, falls are a major public health problem that can cause morbidity, including fracture and disability, and mortality in older people. Exercise therapy is widely recommended, and it is frequently regarded as the gold-standard strategy for preventing falls in both community-dwelling and institutionalized older people. This review synthesizes published findings on feasible, low-technology, low-cost equipment, and easy-to-follow effective fall prevention interventions in healthy older adults. According to the evidence presented in this review, home-based balance and strengthening training programs utilizing low-cost equipment such as foam balance pads, steps, dumbbells, and elastic bands are more cost-effective and feasible exercises for fall prevention in older adults who do not have cognitive impairments. The Otago program, Lifestyle Approach to reducing Falls through Exercise (LiFE) program, and Ossébo exercise program are some of the best-known examples. Physiotherapists will benefit from this updated review, which rates different simple fall prevention programs used worldwide for both community-dwelling and institutionalized older adults.

Preliminary Study of Vibrotactile Feedback during Home-Based Balance and Coordination Training in Individuals with Cerebellar Ataxia.

Intensive balance and coordination training is the mainstay of treatment for symptoms of impaired balance and mobility in individuals with hereditary cerebellar ataxia. In this study, we compared the effects of home-based balance and coordination training with and without vibrotactile SA for individuals with hereditary cerebellar ataxia. Ten participants (five males, five females; 47 ± 12 years) with inherited forms of cerebellar ataxia were recruited to participate in a 12-week crossover study during which they completed two six-week blocks of balance and coordination training with and without vibrotactile SA. Participants were instructed to perform balance and coordination exercises five times per week using smartphone balance trainers that provided written, graphic, and video guidance and measured trunk sway. The pre-, per-, and post-training performance were assessed using the Scale for the Assessment and Rating of Ataxia (SARA), SARAposture&gait sub-scores, Dynamic Gait Index, modified Clinical Test of Sensory Interaction in Balance, Timed Up and Go performed with and without a cup of water, and multiple kinematic measures of postural sway measured with a single inertial measurement unit placed on the participants’ trunks. To explore the effects of training with and without vibrotactile SA, we compared the changes in performance achieved after participants completed each six-week block of training. Among the seven participants who completed both blocks of training, the change in the SARA scores and SARAposture&gait sub-scores following training with vibrotactile SA was not significantly different from the change achieved following training without SA (. However, a trend toward improved SARA scores and SARAposture&gait sub-scores was observed following training with vibrotactile SA; compared to their pre-vibrotacile SA training scores, participants significantly improved their SARA scores ( and SARAposture&gait sub-scores (. In contrast, no significant changes in SARA scores and SARAposture&gait sub-scores were observed following the six weeks of training without SA compared to their pre-training scores immediately preceding the training block without vibrotactile SA (. No significant changes in trunk kinematic sway parameters were observed as a result of training (. Based on the findings from this preliminary study, balance and coordination training improved the participants’ motor performance, as captured through the SARA. Vibrotactile SA may be a beneficial addition to training regimens for individuals with hereditary cerebellar ataxia, but additional research with larger sample sizes is needed to assess the significance and generalizability of these findings.

Barriers and enablers for older adults participating in a home-based pragmatic exercise program delivered and monitored by Amazon Alexa: a qualitative study

BackgroundThe remote delivery and monitoring of individually-tailored exercise programs using voice-controlled intelligent personal assistants (VIPAs) that support conversation-based interactions may be an acceptable alternative model of digital health delivery for older adults. The aim of this study was to evaluate the enablers and barriers for older adults participating in a home-based exercise program delivered and monitored by VIPAs.MethodThis qualitative study used videoconferencing to conduct semi-structured interviews following a 12-week, prospective single-arm pilot study in 15 adults aged 60 to 89 years living alone in the community. All participants were prescribed an individualized, brief (10 min, 2–4 times per day), home-based muscle strengthening and balance exercise program delivered and monitored using an Amazon Echo Show 5 device (Alexa). Qualitative interview data were analysed using inductive thematic analysis.ResultsAll 15 participants (aged 70.3 ± 4.3 years, mean ± SD) attended the semi-structured interview. Themes including enjoyability and ease of use, social engagement and motivation were enablers for participation in the exercise program. Errors in voice recognition, lack of feedback, and preference for other existing digital health modes of exercise delivery were barriers associated with the Alexa technology.ConclusionsThis qualitative study identified enablers and barriers associated with using an Alexa device to deliver and monitor an individualized, home-based exercise program in older adults living alone. Future interventions using VIPAs should focus on reducing technical errors, providing regular exercise feedback, and comparing participants’ experiences of exercise programs delivered by VIPAs to programs delivered via other digital health tools.

The effectiveness of home-based balance and pulmonary rehabilitation program in individuals with chronic obstructive pulmonary disease: a randomized controlled trial.

Balance impairment and increased fall risk have been demonstrated in individuals with chronic obstructive pulmonary disease (COPD). However, studies investigating the effects of balance training especially when combined with pulmonary rehabilitation (PR) program in home-based setting are scarce. To examine whether adding balance training to home-based pulmonary rehabilitation improves balance, fall risk, and disease-related symptoms in individuals with COPD. Randomized, controlled, assessor-blinded trial with parallel two-group design. Home-based setting. Forty-eight individuals diagnosed with COPD. Participants with COPD were randomly allocated to either a home-based PR or home-based balance training combined with PR (PR-BT) group (24 per group). Both groups exercised three days per week for eight-week. Primary outcomes were fall risk index and functional balance as measured by the Physiological Profile Assessment (PPA) and Timed Up and Go (TUG), respectively. Secondary outcomes were the Activities-specific Balance Confidence (ABC), Modified Medical Research Council dyspnea (mMRC), Six-Minute Walk Test (6MWT), and COPD assessment test (CAT). All outcome measures were assessed at baseline, post-intervention, and three-month follow-up. All participants completed the trial, with no reported adverse events. At post-intervention, the PR-BT group demonstrated significantly greater improvements in PPA fall risk score (PR-BT: 1.1±0.8, PR: 2.4±1.5), TUG (PR-BT: 10.7±1.3, PR: 14.4±4.4 s) and these improvements remained at three-month follow-up (all P<0.01). The ABC, mMRC, and CAT scores were also significant better for the PR-BT than the PR group both after intervention and at three-month follow-up (all P<0.05). Eight-week home-based balance and PR program is effective in improving balance as well as dyspnea, and well-being in individuals with COPD. Home-based balance and PR program is a promising approach for COPD rehabilitation especially in patients who are at risk of falls.

Effects of home-based specific and comprehensive balance-training programs on balance and functional status in healthy older adults.

The elderly population is increasing worldwide, and the decline in physical function resulting from this is a critical issue that, especially, leads to a disorder of balance. To investigate the effect of home-based specific and comprehensive balance training on balance and functional status in older adults. Forty elderly men were randomized to conditions specific (n=13) and comprehensive (n=14) balance training or control (n=13). The exercises were performed individually at each subject's home three times a week for ten weeks. The BESTest total and subsection scores, Activities-specific Balance Confidence (ABC) score, gait speed, timed-up-and-go (TUG), and functional gait assessment were evaluated at baseline, immediately after training and at 4-week follow-up. After the intervention, both intervention groups showed more significant improvements than the control group in all variables except section II of BESTest. At follow-up, significantly more gains than control were observed in all variables except section II of BESTest in the specific group and sections II and III in the comprehensive group. Our findings provide evidence that these home-based balance training regimens can enhance balance and functional status in aged individuals. Therefore, at present, because of the coronavirus disease 19 stay-at-home restrictions, it seems that these interventions are applicable strategies for the elderly when access to facilities or opportunities for physical activity outside the home is restricted for all ages, especially the elderly.

Delivery of Home-Based Exercise Interventions in Older Adults Facilitated by Amazon Alexa: A 12-week Feasibility Trial.

To evaluate the feasibility of using voice-controlled intelligent personal assistants (VIPAs) to remotely deliver and monitor an individually-tailored, home-based exercise program to older adults living independently and alone. 12-week, prospective single-arm feasibility study. Community residences. 15 adults aged 60 to 89 years living alone. All participants were prescribed home-based muscle strengthening, weight-bearing impact and balance exercises, increasing from two to four 10-minute sessions per day over 12 weeks. Sessions were delivered using VIPAs (Amazon Alexa Echo Show 5; "Alexa") and a novel software program ("Buddy Link"). The program was individualized by an exercise physiologist based on participant voice responses to Alexa questions. Study outcomes were feasibility (rate of retention, adherence, and adverse events), usability (System Usability Scale) and changes to quality of life (European Quality of Life Scale), and lower-extremity function (30 second sit-to-stand test). All 15 participants (mean age, 70.3 years) completed the study (retention 100%). Mean adherence to the exercise program was 115% (i.e., collectively all participants were prescribed 8640 exercises but completed 9944 exercises) with no adverse events reported to be related to the intervention and usability scored as above average (75/100). Other outcomes did not significantly change across the 12-week follow-up (all P>0.05). In this feasibility study of community-dwelling older adults living alone, a home-based exercise program delivered and monitored remotely by an exercise physiologist using VIPAs was safe and feasible.

Effect of Four Weeks of Home-Based Balance Training on the Performance in Individuals with Functional Ankle Instability: A Remote Online Study.

The purpose of the current study is to evaluate the effect of 4 weeks of home-based balance training (HBBT) on the performance of individuals with functional ankle instability (FAI) in daily activities and sports. Thirty college students diagnosed with FAI and with a mean weight of 79.8 ± 3.4 kg, height of 182.5 ± 5.1 cm, age of 23.5 ± 1.2 years, and instability score of 20 ± 2.3 were selected to participate in this study and were randomly divided by computer-generated methods into two groups: the HBBT group and the control group (CG), each consisting of 15 subjects. The HBBT group performed the program at home for 4 weeks, while the CG was non-exercise. Before and after the 4 weeks of exercise program, a form containing the foot and ankle ability measure for daily activities and sports was completed by the individuals. For data analysis, intra- and inter-group comparisons were performed using paired and independent sample t-tests, respectively, at a significance level of p ≤ 0.05. The results showed that 4 weeks of progressive HBBT were sufficient to significantly improve the measurement of the ability of ankle and foot function in individuals with FAI, even with a total volume of only 60 min per week. Accordingly, it is suggested that individuals with FAI can benefit from short-term HBBT programs, which are simple yet powerful enough to promote improvements in daily activities.

BACKGROUND Individuals with Parkinson’s disease (PD) experience reduced balance ability and are prone to fall. As the disease advances with age, the traditional forms of physiotherapy are prone to fail in long-term exercise intervention as patients lose interest in performing the exercises. The use of virtual reality game technology consists of tasks in virtual environments that combine physical and cognitive demands in a fun and motivating manner which leads to adherence in a long-term exercise intervention. The objectives of the study were to know the adherence of Kinect adventure games in individuals with PD by attendance percentage of prescribed sessions and analyse the impact of balance after the games in them. METHODS An experimental study with pre-post design in which 11 individuals were selected, with a mean age of 67.8 years. Home-based balance exercises were given three days a week up to 6 weeks (18 sessions). Kinect adventure games were implemented for another six weeks. Adherence was measured by attendance percentage in terms of the frequency of sessions completed. The secondary outcome measure was to assess balance. Participants were evaluated before intervention and post-intervention using BESTest. Descriptive statistics were used to compare the BESTest scores of pre and post-intervention. RESULTS The adherence percentage of Kinect adventure game therapy was 38 %. The adherence percentage of home-based balance exercises was only 9 %. The best scores improved in home-based balance exercise compared to Kinect adventure game therapy. CONCLUSIONS The participants with Parkinson’s disease did not adhere to Kinect adventure game therapy. For the attended sessions the balance improved for home-based balance exercise compared to Kinect game therapy. KEY WORDS Exercise Barrier, Adherence, Balance Training, Virtual Reality, Video Games

The Effect Of Exercise On Chemotherapy Completion In Advanced Stage Cancers: The ENACT Trial

Exercise during chemotherapy is safe, feasible, and effective at improving physical and patient-reported outcomes and has been suggested to help improve chemotherapy completion rates. Few trials have reported these clinical outcomes and previous reports have only included one cancer site and mostly early-stage cancers. PURPOSE: To evaluate the effect of exercise on chemotherapy completion rates in advanced stage cancer patients. METHODS: The Exercise in All Chemotherapy (ENACT) trial was a single-arm pragmatic outpatient exercise trial for adults with solid tumors receiving chemotherapy. Seventy-one adults with advanced stage cancer (48F, 58.90 ± 11.20 years, 28 Stage 3) enrolled in ENACT. Patients were given home-based resistance, aerobic, flexibility, and balance exercises. Chemotherapy schedules and dosage changes for Stages 3 and 4 breast (BCa), gastrointestinal (GI), and pancreatic (PCa) cancer patients were obtained via the electronic health record. We also examined the effect of low (<70%) and high (>70%) exercise adherence on relative dose intensities (RDI) and dose delays. RESULTS: RDI differed by cancer sites: BCa (96.15%), GI (75.18%), and PCa (62.00%). BCa had a significantly higher RDI compared to GI (MD = 20.97, SE = 6.44, p = .005) and PCa (MD = 34.15, SE = 7.65, p < .001). Further, BCa patients had less weeks of dose delays (0.46 ± 1.11) compared to GI (1.24 ± 2.57), and PCa (1.19 ± 1.87). Exercise adherence had an effect on RDI and dose delays. BCa patients with low adherence had a RDI of 87.44% compared to 95.97% for high adherence. PCa patients with low adherence also had a lower RDI of 50.38% compared to 63.72% for patients with high adherence. For BCa and PCa patients, a sample size of 186 and 76, respectively, would yield 80% statistical power for detecting the observed differences. BCa patients who exercised more had no dose delays, while those who exercised less had average of 0.98 ± 1.51 weeks of dose delays. GI patients with high exercise adherence had 0.66 ± 1.51 weeks of dose delays compared to 1.68 ± 3.17 weeks for those with low exercise adherence. CONCLUSIONS: We observed that being more physically active resulted in higher RDIs and shorter time to complete chemotherapy. Although our results are not statistically significant, they show promise to the salutary effect of exercise in advanced stage patients.
