RESUMEN
BACKGROUND: Community stroke rehabilitation teams (CSRT) provide an individualized home-based rehabilitation service to patients recovering from stroke. OBJECTIVE: To examine whether there is an improvement in the social participation of patients who received a rehabilitation program provided by CSRT. The secondary objectives were to show if there is an improvement in the patients' quality of life and a reduction in the caregiver burden. METHODS: Retrospective cohort study, pragmatic in real-care conditions. The rehabilitation program delivered by the CSRT was adapted to the needs of the patients and caregivers. The outcome questionnaires included: the Frenchay Activity Index (FAI), the Minizarit, the EuroQol EQ5D, and the Barthel Index. The primary outcome measure was the FAI. RESULTS: We included 206 patients followed by the CSRT over the 2018-2020 study period, for whom the primary endpoint was present. The mean age was 66.3 ± 12.7 years, the post-stroke delay was 16.4 ± 32.7 months, and the Barthel index was 66.42 ± 12.6. The duration of the rehabilitation program was on average 162 ± 109 days. We observed a significant improvement in the FAI, from 12.9 ± 10.4 to 17.85 ± 12.4 (p < 0.00001); in the EuroQol, from 57.51 ± 19.96 to 66.36 ± 18.87 (p < 0.00001); in the mini-Zarit, from 2.49 ± 1.75 to 2.06 ± 1.67 (p = 0.0002); and in the Barthel index, from 66.42 ± 12.67 to 84.81 ± 23.70 (p < 0.001). CONCLUSION: Patients who received a rehabilitation program by the CSRT have an improvement in their social participation, and their informal caregivers have a reduction in their burden.

OBJECTIVE: To assess the impact of cognitive Dual Task (DT) during walking on the energy cost of walking (Cw) in individuals with subacute stroke. The secondary objective was to determine whether there is an association between the Cw and cortical activity of the prefrontal area. METHODS: Any individual with stroke localized in the temporal-parietal regions and able to walk without human assistance was included. Cw and prefrontal cortical activity, recorded by fNIRS, were measured during simple task walking activity and cognitive dual task during walking. RESULTS: Nineteen individuals with stroke (age = 67.7 ± 9.6 yrs) were included. The cognitive DT during walking resulted in an increase in Cw of 23.1%; 95%CI [13.1%; 34.5%]. The increase in Cw in cognitive DT was correlated with the Cw for the single task walking activity (r = 0.48, p < 0.01) as well as the predominance of cortical activity of the prefrontal area in the contralesional hemisphere (r = -0.33, p < 0.01). CONCLUSION: There is an increase in Cw during the cognitive DT. This increase is even more significant, as the Cw of the single task walking activity is high, and the cortical activity of the prefrontal areas predominates in the contralesional hemisphere.

OBJECTIVE: To evaluate the validity and test-retest reliability of physical activity trackers (accelerometer, multisensor, smartphone, pedometer) for estimating energy expenditure during walking in individuals with stroke. DATA SOURCES: Webline, MEDLINE, Scopus, ScienceDirect, Bielefeld Academic Search Engine, and Wiley Online Library databases from 1980 to November 2020. STUDY SELECTION: The inclusion criteria were studies that examined the validity of portable physical activity trackers for estimating energy expenditure in individuals with stroke during walking activities compared to indirect calorimetry. DATA EXTRACTION: This systematic review was reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the methodological quality of the included studies was determined with the Quality Assessment of Diagnostic Accuracy Studies. The study selection was made by 2 blind observers. DATA SYNTHESIS: We screened 3677 articles; 3647 were excluded after duplicate removal and title and abstract review. Thirty articles were included for full-text analysis. Eight articles met the inclusion criteria (184 individuals with stroke) and were included in the data synthesis and meta-analysis. For all monitors, activities, and placements, the overall level of correlation with indirect calorimetry was 0.34 (95% confidence interval [CI], 0.23-0.44). After subgroups analysis, we showed that type and placement have no effect on the level of validity. Test-retest reliability was high, with intraclass correlation equal to 0.89 (95% CI, 0.76-0.95). CONCLUSIONS: Portable physical activity monitors provided a low correlation with indirect calorimetry during walking in individuals with stroke. It seems essential to pursue studies to improve their validity in this population.

Background and objective: Duration of rehabilitation and active participation are crucial for gait rehabilitation in the early stage after stroke onset. Virtual reality (VR) is an innovative tool providing engaging and playful environments that could promote intrinsic motivation and higher active participation for non-ambulatory stroke patients when combined with robot-assisted gait training (RAGT). We have developed a new, fully immersive VR application for RAGT, which can be used with a head-mounted display and wearable sensors providing real-time gait motion in the virtual environment. The aim of this study was to validate the use of this new device and assess the onset of cybersickness in healthy participants before testing the device in stroke patients. Materials and Methods: Thirty-seven healthy participants were included and performed two sessions of RAGT using a fully immersive VR device. They physically walked with the Gait Trainer for 20 min in a virtual forest environment. The occurrence of cybersickness, sense of presence, and usability of the device were assessed with three questionnaires: the Simulator Sickness Questionnaire (SSQ), the Presence Questionnaire (PQ), and the System Usability Scale (SUS). Results: All of the participants completed both sessions. Most of the participants (78.4%) had no significant adverse effects (SSQ < 5). The sense of presence in the virtual environment was particularly high (106.42 ± 9.46). Participants reported good usability of the device (86.08 ± 7.54). Conclusions: This study demonstrated the usability of our fully immersive VR device for gait rehabilitation and did not lead to cybersickness. Future studies should evaluate the same parameters and the effectiveness of this device with non-ambulatory stroke patients.

OBJECTIVE: To evaluate the association between self-selected walking speed (Sfree), oxygen consumption at Sfree (Vo2free), the oxygen cost of walking (Cw) at Sfree, and mobility independence and independence for activities of daily living in individuals poststroke. DESIGN: Cross-sectional study. SETTING: Hospital. PARTICIPANTS: Individuals with stroke who were able to walk without human assistance were included. We included 90 individuals (N=90; mean age, 63.5±14.0y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Cw was captured during walking from measurements of Sfree and Vo2free. We assessed mobility independence based on the modified Functional Ambulation Classification (mFAC) and independence in activities of daily living by the Barthel Index (BI). Multiple linear regression analyses were performed to evaluate the independence of Cw, Vo2free, and Sfree from the determination of BI and mFAC among the various characteristics of the population (age, stroke delay, body mass index, motor function, spasticity). RESULTS: We reported Cw=0.36 mL/kg/m (interquartile range [IQR]=0.28 mL/kg/m), Sfree=0.60±0.32 m/s, Vo2free=11.2 mL/kg/min (IQR=1.8 mL/kg/min). The multiple linear regression analyses showed that Cw and Sfree were independently associated with the BI (P<.01) and the mFAC (P<.01) scores. Vo2free was not found to be an explanatory variable of functional independence (P>.05). CONCLUSIONS: Cw was independently associated with functional independence. This association appears to be primarily determined by Sfree and not Vo2free, underscoring the importance of evaluating and acting on Sfree to improve the functional independence of individuals with stroke.

Objective: To explore the validity of energy expenditure estimates using the SenseWear Armband during a sequence of four daily living activities in patients post-stroke. Method: Patients with stroke who were able to walk during 6 min without human assistance were asked to wear the SenseWear Armband on the non-paretic arm while performing transfers, a manual task, walking, and walking up and down stairs. The energy expenditure estimated using the SenseWear Armband was compared to the energy expenditure calculated from oxygen consumption, measured by a portable indirect calorimeter (Metamax 3B). The mean of energy expenditure was pooled for each task. Accuracy was explored by mean bias (MB) of Bland-Altman analysis and root mean square error (RMSE), agreement by 95% of limits of agreement (95%LoA) and coefficient of correlation (r). Results: Thirty-eight participants (65.7 ± 13.5 years) were included. The SenseWear Armband globally underestimated energy expenditure, MB = 9.77 kcal for the whole sequence. RMSE were large, accounting for 15% to 41% of the measured energy expenditure. Agreement was low with r < 0.70 and 95%LoA from 42% to 93% of the measured energy expenditure. Conclusions: This study reported a global underestimation and a low level of agreement of the energy expenditure estimated by SenseWear Armband in four daily living activities in patients after stroke.

BACKGROUND: Health professionals need valid devices to assess a stroke individual's ability to walk. The aim was to evaluate the validity of the estimation of the walked distance by wearable devices and the impact of the sensor's position in stroke individuals. METHODS: Post-stroke patients able to walk without human assistance were equipped with several wearable devices: pedometers, Actigraph, and Sensewear Armband placed according to the manufacturers' recommendations. Participants walked for 6 min at a comfortable speed wearing all sensors at the same time. We analyzed the validity of sensor-estimated distances according to their position using Bland-Altman analysis, root-mean-square error, and coefficient of correlation. RESULTS: In total, 35 individuals were included (mean age = 65 ± 15 years). The best estimations were given by the Actigraph worn on the unaffected ankle (mean bias (MB) = 22.6 ± 32.4 m; p = 0.37) and by the pedometer worn on the unaffected hip (MB = 20.5 ± 24.6 m; p = 0.46). The other sensors and positions provided large estimation errors over 95 m (p < 0.05). CONCLUSION: This study led to a recommendation of a pedometer worn on the unaffected hip or an Actigraph worn on the unaffected ankle to get a valid estimation of the distance walked by stroke individuals.
RESUMEN
OBJECTIVE:: To explore the validity of the Actigraph and the influence of the placement of the sensor when estimating the active energy expenditure in four common daily activities (transfers, manual task, walking in overground and walking up and down stairs) in stroke survivors. DESIGN:: Cross-sectional study. SETTING:: Department of Physical Medicine and Rehabilitation. SUBJECTS:: A total of 46 subjects affected with stroke sequelae were wearing the Actigraph on three different locations-ankle, hip and wrist on the non-affected side-and performed four tasks: transfers, manual task, walking on flat ground and walking up and down stairs. MAIN MEASURES:: The values of active energy expenditure estimated by the Actigraph were compared to those measured by a portable breathing gas exchange analyzer Metamax3B. The accuracy and agreement between Actigraph and Metamax values were analyzed with mean bias, root mean square error, correlation coefficient and Bland-Altman plots for each task and each sensor location. RESULTS:: The mean bias between the Metamax and Actigraph placed on wrist, hip and ankle were, respectively, MD = 1.16 kcal (%MD = 3%), MD =-20.44 kcal (%MD =-58%) and MD = 17.64 kcal (%MD = 50%). The agreement with the Metamax was poor in general regardless of the sensor location and type of task ( r = 0.12-0.58). CONCLUSION:: This study found large differences and a poor agreement between the active energy expenditure as measured by the Actigraph and the Metamax according to the location of the sensor and the type of task performed by the subject.

Work-related upper extremity disorders (WRUEDs) are highly prevalent and costly. Development of fatigue is thought to be one of the causes of WRUEDs. Perceived fatigue can be assessed with the Borg CR Scale® (Borg CR10). The objective was to validate the Borg CR10 for the evaluation of shoulder perceived fatigue during lifting tasks. Seventy adults in working age performed three rhythmic lifting tasks with two loads (15% and 30% of maximal voluntary contraction). Using generalized repeated-measures ANOVA (Generalized Estimating Equations), statistically significant Task and Load effects (p < 0.001), as well as Task × Load interaction effects (p < 0.0001) were observed on Borg CR10, without any influence of sex. The Borg CR10 is a valid tool to assess shoulder perceived fatigue as it can discriminate between tasks of different difficulty levels in term of complexity, height, and resistance, regardless of sex.

Increased physical activity has been demonstrated as a relevant treatment after a stroke, with positive effects on impairment recovery, activity limitation, social participation and quality of life. Furthermore, PA is now recommended as part of the stroke recovery pathway, starting during inpatient care and extending through rehabilitation and community integration. The purpose of this presentation is to describe how current technologies may facilitate a continuity of care for stroke survivors. We present a synthesis of 8 studies that we have conducted to date to assess and monitor the activity level of post-stroke patients at home. The results of these studies show that home rehabilitation of post-stroke patients requires the use of individualized monitoring criteria to optimize patient care. To encourage the patient to increase his level of moderate physical activity and reduce his sedentary time, it would be recommended to propose a regularly monitored and structured program.

The electromyography (EMG) cocontraction index (CCI) given by the antagonistic/agonistic Root Mean Square (RMS) amplitude ratio of the same muscle is a qualified biomarker used for spastic cocontraction quantification and management in cerebral palsy children. However, this normative EMG ratio is likely subject to a potential source of errors with biased estimates when measuring the gastrocnemius plantar flexors activity. Due to the uneven distribution of electrical activity within the muscle volume, cocontraction levels can be misestimated, if EMGs are obtained from the sole traditional bipolar sensor location recommended by SENIAM. This preliminary study, on 10 healthy children (mean age 10 yr), investigated whether surface EMG detected proximally and distally via two pairs of bipolar electrodes, within the medial gastrocnemius (MG), provides a significant difference in CCI estimates during non-dynamic (isometric dorsiflexion) and dynamic (swing phases of gait) conditions. Gait cycles were extracted from Inertial Measurement Unit sensors. Medial gastrocnemius activity was greater distally than proximally during plantar flexion when it acts as an agonist (~24±18%) and it was greater proximally during dorsiflexion (~23±9%) when it is acting as an antagonist. As a direct consequence, CCI estimates from the conventional sensor location were significantly different (~36%) from the CCIs computed by considering broader MG regions. This difference arose in all subjects during isometric efforts and in two of 10 healthy children during the swing phase of gait who presented cocontraction patterns ( [Formula: see text]). EMG bipolar sampling encompassing proximal and distal gastrocnemius muscle regions may reduce bias in CCI computation and provide a more representative and accurate cocontraction index that is especially important for comparisons to the diseased state.

Background: Stroke causes psychological disorders and cognitive impairments that affect activities of daily living and quality of life. Physical activity (PA) in stroke recovery is beneficial. The benefits of PA on quality of life after stroke are less documented. The aim of the study was to evaluate the effect of a home-based PA incentive program at home in post-stroke patients in the subacute phase on quality of life. Methods: This is a prospective, randomized, single-blind, and monocentric clinical trial. Eighty-three patients were randomly assigned to either an experimental group (EG; n = 42) or to a control group (CG; n = 41). The experimental group followed a home-based PA incentive program for 6 months. Three incentive methods were used: daily monitoring with an accelerometer, weekly telephone calls, and home visits every three weeks. Patients were evaluated before intervention (T0) and after intervention (T1) at 6 months. The control group was a non-intervention group receiving usual care. The outcome was the quality of life with the EuroQol EQ-5D-5L evaluated at baseline and 6 months post-intervention. Results: The mean age was 62.2 years ± 13.6 with a post-stroke time of 77.9 ± 45.1 days. The mean values of the utility index (EQ-5D-5L) in the control group and experimental group at T1 were 0.721 ± 0.207 and 0.808 ± 0.193, respectively (p = 0.02). Discussion: Our study shows a significant difference in the Global QOL index (EQ-5D-5L) between the two groups of subacute stroke patients after 6 months of the individualized coaching program, which combined home visits and weekly telephone calls.

BACKGROUND: The increased energy cost of walking (Cw) for stroke patients affects the walking function and walking independence of stroke patients. However, its impact on quality of life (QoL) has never been studied. OBJECTIVE: Assess the association between Cw and QoL for post-stroke individuals in the year following hospital discharge. METHOD: Thirty-seven individuals with stroke were included. QoL was assessed by the EuroQol-5 Dimensions on the day after hospital discharge (T0), at six months (T1) and at one year after hospital discharge (T2). Concomitant an evaluation of Cw, mood disorders (HADS), fatigue, independence in activities of daily living and the presence of a family caregiver was performed. The association between QoL and the different covariates was analyzed using multiple regression analysis. RESULTS: At T2, data from 29 individuals were analyzable. Multiple regression analyses showed Cw had a significant influence on the QoL at T1 (coeff -0.42 (-0.71 to -0.12), P = .008) and T2 (coeff -0.49 (-0.71 to -0.26), P < .001). HADS score was the only other variable to significantly impact variances of QoL at T0, T1 and T2. Moreover, we showed that Cw at T0 explained 29% of variances of QoL at T1 and 42% at T2. CONCLUSION: Cw appears to be an independent factor in the QoL of individuals with stroke at six months and one year after hospital discharge. In addition, the initial Cw and HADS are predictive of QoL at one year highlighting the importance of early interventions in these two dimensions to improve QoL over the long term.
RESUMEN
Autonomic imbalance in stroke is characterized by increased sympathetic activity and reduced vagal nerve activity. Physical activity could be a strategy to counteract autonomic control impairments after a stroke. The aim of the study was to evaluate the effect on heart rate variability of a 6-month coaching program in a home setting in subacute stroke patients. Eighty-four stroke patients participated in the study. They were randomly assigned to the experimental group or the control group. The intervention was a coaching program, consisting of physical activity, home visits and a weekly phone call. Patients were evaluated after hospital discharge (T0) and at the end of the 6-month period (T1). Heart rate variability measures were recorded in the supine and orthostatic positions. Time and frequency domain values were treated using Kubios. Distance on 6 minutes walking test (6MWT), Barthel and motricity index and modified functional ambulation categories were evaluated. No effects were found on time and frequency domain values in the supine and orthostatic positions in either group. Walking distance on 6MWT increased significantly between T0 and T1 in experimental group (377 ± 141-448 ± 140 m; P < 0.02) with no effects in control group (373.6 ± 150.6-394.6 ± 176.4 m). No other functional effects were found. A coaching program in a home setting had no effect on heart rate variability, probably due to time of recovery and exercise intensity. Future research is needed to understand the lack of changes in heart rate variability by physical activity in subacute stroke patients.

BACKGROUND: The integration of oxygen cost into the accelerometer's algorithms improves accuracy of total energy expenditure (TEE) values as post-stroke individuals walk. Recent work has shown that oxygen cost can be estimated from specific prediction equations for stroke patients. OBJECTIVE: The objective is to the validity of the different oxygen cost estimation equations available in the literature for calculating TEE using ActigraphGT3x as individuals with stroke sequelae walk. METHOD: Individuals with stroke sequelae who were able to walk without human assistance were included. The TEE was calculated by multiplying the walking distance provided by an ActigraphGT3x worn on the healthy ankle and the patient's oxygen cost estimated from the selected prediction equations. The TEE values from each equation were compared to the TEE values measured by indirect calorimetry. The validity of the prediction methods was evaluated by Bland-Altman analysis (mean bias (MB) and limits of agreement (LoA) values). RESULTS: We included 26 stroke patients (63.5 years). Among the selected equations, those of Compagnat and Polese obtained the best validity parameters for the ActigraphGT3x: MBCompagnat = 1.2 kcal, 95% LoACompagnat = [-12.0; 14.3] kcal and MBPolese = 3.5 kcal, 95% LoAPolese = [-9.2; 16.1] kcal. For comparison, the estimated TEE value according to the manufacturer's algorithm reported MBManufacturer = -15 kcal, 95% LoAManufacturer = [-52.9; 22.8] kcal. CONCLUSION: The Polese and Compagnat equations offer the best validity parameters in comparison with the criterion method. Using oxygen cost prediction equations is a promising approach to improving assessment of TEE by accelerometers in post-stroke individuals.

BACKGROUND: Stroke is the leading cause of acquired disability in France. While 90% of patients recover the ability to walk, it is often limited with a steady speed of approximately 0.7 m/s. This limitation of walking activity is partly related to a decrease in strength associated with more or less significant spasticity. In particular, it seems that the strength of the dorsiflexor muscles is directly related to walking speed. We hypothesise that a protocol based on gestural repetition targeted at the ankle during the subacute phase potentiates the recovery of motor control, improving walking activity, and participates in recovering better social participation. METHODS: An estimated total of 60 patients with subacute stroke will be recruited to participate in this multicentre, interventional, prospective, randomised controlled trial. All participants will benefit from conventional rehabilitation. In addition, the experimental group will take part in an ankle isokinetic rehabilitation programme for 6 weeks (at least 25 sessions). The control group will receive the same duration of conventional rehabilitation. The primary outcome measure will be a 10-m walking speed at post-intervention. Secondary outcomes will include social participation, walking spatio-temporal parameters, and dorsiflexor strength. Outcome measurements will be taken at baseline, immediately after treatment (6 weeks), then at 6 months and 1 year of follow-up. DISCUSSION: This study aims to provide scientific evidence that a protocol based on an early over-solicitation of the ankle dorsiflexor muscles to promote their "awakening" can serve to achieve a more effective walking activity, which in turn encourages social participation following discharge from the hospital. This protocol should also help optimise physical medicine and rehabilitation practices: the more systematic use of the isokinetic dynamometer as a technique associated with, and integrated into the conventional rehabilitation protocol would allow an objective evaluation of the rehabilitation benefits and should increase the rehabilitation gain in central nervous system disorders. TRIAL REGISTRATION: Limoges University Hospital is the sponsor of this research (Unique Protocol ID: 87RI18_0010) This research is supported by the French Ministry of Health (PHRC 2020-A03328-31) and is conducted with the support of DGOS (PHRC interregional - GIRCI SOHO). The study protocol was approved by the French Human Subjects Protection Review Board (Comité de Protection des Personnes Nord-Ouest III) on February 23, 2021. The trial was registered in the ClinicalTrials.gov registry ( NCT04800601 ) on March 16, 2021.

Foot drop is a common disability in post-stroke patients and represents a challenge for the clinician. To date, ankle foot orthosis (AFO) combined with conventional rehabilitation is the gold standard of rehabilitation management. AFO has a palliative mechanical action without actively restoring the associated neural function. Functional electrical stimulation (FES), consisting of stimulation of the peroneal nerve pathway, represents an alternative approach. By providing an FES device (Bioness L-300, BIONESS, Valencia, CA, USA) for 6 months to a post-stroke 22-year-old woman with a foot drop, our goal was to quantify its potential benefit on walking capacity. The gait parameters and the temporal evolution of the speed were collected with a specific connected sole device (Feet Me®) during the 10-m walking, the time up and go, and the 6-minute walking tests with AFO, FES, or without any device (NO). As a result, the walking speed changes on 10-m were clinically significant with an increase from the baseline to 6 months in AFO (+0.14 m.s-1), FES (+0.36 m.s-1) and NO (+0.32 m.s-1) conditions. In addition, the speed decreased at about 4-min in the 6-minute walking test in NO and AFO conditions, while the speed increased in the FES conditions at baseline and after 1, 3, and 6 months. In addition to the walking performance improvement, monitoring the gait speed in an endurance test after an ecological rehabilitation training program helps to examine the walking performance in post-stroke patients and to propose a specific rehabilitation program.

AIM: To test the validity of Borg's 6-20 rating of perceived exertion scale in assessing the exertion intensity over a multi-activity session in young and older adults.Materials and methods: This cross-sectional study included 56 healthy participants. All participants underwent a single session of activities including working on a computer, treadmill walking, biking, and treadmill running. RESULTS: Results showed a non-significant correlation between the overall perceived exertion and energy expenditure in young people (Rho=-0.05, p=0.75) and in older adults (Rho=-0.05, p=0.78) for the whole session. However, results showed that older adults perceived significantly higher exertion compared to young people while working on a computer, walking and running, whereas they presented lower energy expenditure while resting and working on a computer. CONCLUSIONS: Combining the perceived exertion method with other commonly used methods to estimate exercise intensity would be recommended for older adults.

BACKGROUND: The oxygen cost of walking (Cw) represents the energy expenditure involved in walking, which is a major concern when quantifying physical activity in stroke. Recent studies have reported that Cw may be estimated accurately with a prediction equation using the self-self-selected walking speed (Sfree). RESEARCH QUESTION: To evaluate the validity of Cw estimates according to different modalities of Sfree measurements (10-m walking test, 6-minute walking test, GaitRite system). METHODS: Twenty-one stroke individuals in subacute phase who were able to walk without human aid were included. Cw was estimated from the walking speed measured during a 10-m walking test, a 6-minute walking test and a recording on a GaitRite system. The values of the Cw estimates were compared to those measured by a respiratory gas exchange analyzer (Metamax3b). RESULTS: The findings showed that there is no significant difference between the Cw measured by Metamax3b and the Cw estimates regardless of the modalities used to measure Sfree (Fvalue = 0.02; pvalue = 0.99). The mean bias between Cw measured by the Metamax3b and those estimated using the different Sfree measurement modalities was less than 2.5 % of the mean Cw value. Test retest reliability was excellent with an intraclass correlation coefficient higher than 0.95. SIGNIFICANCE: in stroke survivors who are able to walk independently without human aid, the use of a 10-m walking test, a 6-minute walking test or a GaitRite recording can be considered validated for estimating Cw.

BACKGROUND: The current coronavirus disease (COVID-19) pandemic makes it difficult to obtain physical therapy in rehabilitation centres, particularly for persons with multiple sclerosis (pwMS), who are a population at high risk, since viral infections may contribute to MS exacerbations and relapses. Active video games could be a way to maintain physical therapy at home as part of the rehabilitation. The aim of this review is to summarise the current best evidence for the effectiveness of home-based active video games on gait and balance, user compliance, feasibility and safety for pwMS. METHODS: We searched for studies in five databases (PubMed, Scopus, Cochrane, CINAHL and Science direct) up to October 2020. Selection of studies, extraction of data and methodological quality assessment through the PEDro scale were made independently by two authors and discussed with a third author. RESULTS: Nine studies were included in this systematic review. We found significant improvements in balance; results were mixed concerning mobility, physical activity and gait. Home-based active video games are feasible and safe, with good compliance and adherence. The methodological quality of the studies was moderate (PEDro scale: 5.3 ± 2). CONCLUSION: Overall, home-based active video games were found safe and effective improving static and dynamic balance in pwMS. Compliance was good, probably because it is a motivating and enjoyable training. Active video games can be a relevant alternative for physical rehabilitation at home in pwMS. Future studies should follow more rigorous methodological standards (larger sample sizes, more randomised controlled trials) to improve the quality of evidence and include cost-effectiveness in the analysis.
