Psychometric properties of wearable technologies to assess post-stroke gait parameters: A systematic review.

BACKGROUND: Wearable technologies using inertial sensors are an alternative for gait assessment. However, their psychometric properties in evaluating post-stroke patients are still being determined. This systematic review aimed to evaluate the psychometric properties of wearable technologies used to assess post-stroke gait and analyze their reliability and measurement error. The review also investigated which wearable technologies have been used to assess angular changes in post-stroke gait. METHODS: The present review included studies in English with no publication date restrictions that evaluated the psychometric properties (e.g., validity, reliability, responsiveness, and measurement error) of wearable technologies used to assess post-stroke gait. Searches were conducted from February to March 2023 in the following databases: Cochrane Central Registry of Controlled Trials (CENTRAL), Medline/PubMed, EMBASE Ovid, CINAHL EBSCO, PsycINFO Ovid, IEEE Xplore Digital Library (IEEE), and Physiotherapy Evidence Database (PEDro); the gray literature was also verified. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) risk-of-bias tool was used to assess the quality of the studies that analyzed reliability and measurement error. RESULTS: Forty-two studies investigating validity (37 studies), reliability (16 studies), and measurement error (6 studies) of wearable technologies were included. Devices presented good reliability in measuring gait speed and step count; however, the quality of the evidence supporting this was low. The evidence of measurement error in step counts was indeterminate. Moreover, only two studies obtained angular results using wearable technology. SIGNIFICANCE: Wearable technologies have demonstrated reliability in analyzing gait parameters (gait speed and step count) among post-stroke patients. However, higher-quality studies should be conducted to improve the quality of evidence and to address the measurement error assessment. Also, few studies used wearable technology to analyze angular changes during post-stroke gait.

Physical therapy for the management of global function, fatigue and quality of life in amyotrophic lateral sclerosis: systematic review and meta-analyses.

OBJECTIVES: To critically evaluate the effectiveness of physical therapy interventions in improving global function, quality of life and fatigue in individuals with amyotrophic lateral sclerosis (ALS). DESIGN: Systematic review and meta-analyses. DATA SOURCES: MEDLINE, EMBASE, Cochrane Library (CENTRAL) and Physiotherapy Evidence Database (PEDro) were searched through 31 January 2023. ELIGIBILITY CRITERIA: We included randomised clinical trials (RCTs) that compared physical therapy interventions that act on global function, fatigue and quality of life in individuals with ALS with any other non-physiotherapeutic methods and techniques, placebo or non-intervention. The primary outcome measure was the evaluation of global function. Secondary outcomes were quality of life, fatigue and adverse events. DATA EXTRACTION AND SYNTHESIS: Two independent authors used a researcher-developed extraction form and the Rayyan software to search, screen and code included studies. The risk of bias was assessed using the PEDro scale. Meta-analyses were conducted employing random effects. Outcomes were succinctly presented in Grading of Recommendations, Assessment, Development and Evaluation evidence profiles. RESULTS: Our searches identified 39 415 references. After study selection, three studies were included in the review. Such studies involved 62 participants with a mean age of 54.6 years. In the evaluated trials, 40 were male, while 22 participants were female. Regarding the type of onset of the disease, 58 participants had spinal onset of ALS, and four had bulbar. CONCLUSIONS: Physical therapy intervention may improve the global function of individuals with ALS in the short term; however, clinically, it was inconclusive. In terms of quality of life and fatigue, physical therapy intervention is not more effective than control in the short term. Adverse events are not increased by physical therapy intervention in the short term. Due to significant methodological flaws, small sample sizes, wide CIs and clinical interpretation, our confidence in the effect estimate is limited. PROSPERO REGISTRATION NUMBER: CRD42021251350.

Physical therapy for muscle strengthening in individuals with amyotrophic lateral sclerosis: A protocol for a systematic review and meta-analysis.

INTRODUCTION: People with Amyotrophic Lateral Sclerosis (ALS) can present initially muscle weakness, which is a debilitating symptom that may be improved by engaging in muscle strengthening activities. Currently, the effects of motor interventions for muscle strengthening in people with ALS are unclear. This review intends to analyze the effects of motor interventions for muscle strengthening in individuals with ALS. METHODS AND ANALYSIS: Randomized, non-randomized, and quasi-experimental clinical trials assessing individuals with ALS of both sexes, aged 18 years or older, who have received motor interventions for muscle strengthening considering all practices that can lead to increased strength, endurance, power and muscular hypertrophy will be included. No restriction on language, location, or publication date will be applied. MEDLINE, EMBASE, Cochrane Library (CENTRAL), SPORTDiscus, and Physiotherapy Evidence Database (PEDro) databases will be searched. The US National Institutes of Health Ongoing, ClinicalTrials.gov, and the reference lists of included studies will also be searched. Two reviewers will independently screen titles and abstracts and extract data from included studies. The methodological quality of the included studies will be assessed by the PEDro scale and the certainty of the evidence by the GRADE approach. Disagreements will be resolved by a third researcher. Findings will be presented in text and table formats. A meta-analysis will compare the effects of motor interventions for muscle strengthening versus placebo or other interventions.

Physical therapy for the management of motor symptoms in amyotrophic lateral sclerosis: protocol for a systematic review.

INTRODUCTION: The prescription of an intervention plan can be challenging for the physical therapist, considering clinical phenotypes, individual prognosis and the rapid, progressive and deteriorating nature of amyotrophic lateral sclerosis (ALS). In this context, therapeutic exercises (eg, resistance and aerobic exercises) for patients with ALS remain controversial and may influence the treatment plan. Therefore, this review aims to critically assess whether physical therapy interventions are effective for improving functional capacity, quality of life and fatigue of individuals with ALS. METHODS AND ANALYSIS: Studies will be selected according to eligibility criteria, and language, geographical area or publication date will not be restricted. Four databases will be used: MEDLINE, EMBASE, Cochrane Library (CENTRAL) and Physiotherapy Evidence Database (PEDro). Searches will also be conducted on ClinicalTrials.gov and references from included studies. We plan to conduct the searches between October and December 2022. Two independent authors will examine titles and abstracts and exclude irrelevant studies and duplicates. We will assess the quality of studies and quality of evidence, and disagreements will be resolved with a third researcher. The findings will be presented in the text and tables; if possible, we will perform meta-analyses. ETHICS AND DISSEMINATION: No ethical approval is required because this study does not involve human beings. We will publish our findings in peer-reviewed journals.

Impact of physiotherapy with telerehabilitation on caregivers of patients with neurological disorders: A systematic review protocol.

Introduction: Caregivers are essential during and after rehabilitation but exhibit intense physical and mental burdens due to responsibilities, resulting in stress, irritability, depression, anxiety, pain, and financial distress. Telerehabilitation offers several remote health services that improve time, engagement, and physical and mental health care access. Thus, we outlined a systematic review protocol to evaluate the impact of telerehabilitation on the burden, stress, pain, and quality of life of caregivers of patients with neurological disorders. Methods: Searches will be conducted in Ovid MEDLINE, Pubmed, Scopus, Web of Science, Embase, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, and PsycINFO databases. Clinical trials evaluating the burden, stress, pain, and quality of life of caregivers of patients with neurological disorders using telerehabilitation will be included without publication date or language restriction. Two reviewers will independently select studies from titles, abstracts, and reference lists. The quality of evidence and risk of bias will be assessed according to Cochrane recommendations. Results: This systematic review to be developed will evaluate the impact of telerehabilitation on the burden, stress, pain, and quality of life of caregivers of patients with neurological disorders. Discussion: Caregivers, especially of patients with neurological disorders, need more attention since the overload, stress, duties with other personal responsibilities, and low remuneration may impact the quality of life. Therefore, they need intervention, especially physical therapy via telehealth, which values the time of caregivers and may change their perception of health and quality of life.

Remote versus face-to-face home-based exercise programme in people with amyotrophic lateral sclerosis: protocol for a randomised clinical trial.

INTRODUCTION: Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease with variable and complex clinical manifestations that requires a multidisciplinary approach. However, face-to-face treatment in this population may experience barriers, such as difficulty accessing physical therapists or other professionals. As a result, strategies (eg, telerehabilitation) emerged to facilitate treatment and physical therapy monitoring. This study aims to evaluate the effects of remote versus face-to-face home-based exercise programmes on clinical outcomes and treatment adherence of people with ALS. METHODS AND ANALYSIS: This is a single-blind randomised clinical trial protocol that will include 44 people with clinical diagnosis of ALS at any clinical stage and aged between 18 and 80 years. Participants will be randomised into two groups after face-to-face evaluation and perform a home-based exercise programme three times a week for 6 months. A physical therapist will monitor the exercise programme once a week remotely (phone calls-experimental group) or face-to-face (home visits-control group). The primary outcome measure will be functional capacity (Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised). Secondary outcomes will include disease severity (Amyotrophic Lateral Sclerosis Severity Scale), fatigue (Fatigue Severity Scale), pain (Visual Analogue Scale and body pain diagram), adverse events and adherence rate. Outcomes will be initially evaluated face-to-face and revaluated remotely every 2 months and 1 month after interventions. Linear mixed models will compare outcome measures between groups and evaluations (α=5%). ETHICS AND DISSEMINATION: This study was approved by the research ethics committee of Hospital Universitário Onofre Lopes/Universidade Federal do Rio Grande do Norte (no. 3735479). We expect to identify the effects of an exercise programme developed according to ALS stages and associated with remote or face-to-face monitoring on clinical outcomes using revaluations and follow-up after interventions.

Effects of respiratory physiotherapy in patients with amyotrophic lateral sclerosis: protocol for a systematic review of randomised controlled trials.

INTRODUCTION: Respiratory muscle weakness and ventilatory failure are common complications in patients with amyotrophic lateral sclerosis (ALS) and may lead to death. Respiratory physiotherapy may improve lung function in this population. This study aims to investigate the effects of respiratory physiotherapy on lung function, cough efficacy and functional status of patients with ALS. METHODS AND ANALYSIS: A protocol was published on the International prospective register of systematic reviews (PROSPERO). The research will cover randomised controlled trials, with no language or publication date restriction, available in the following databases: MEDLINE/PubMed, EMBASE, Cochrane Library, Web of Science and Physiotherapy Evidence Database. The research question will be answered using a search strategy adapted for each database. Searches in databases will be conducted from January 2021 to December 2022. Two authors using the Cochrane risk of bias tool for randomised trials V.2 and Grading of Recommendations, Assessment, Development and Evaluations, respectively, will assess risk of bias and quality of evidence independently. According to the results obtained, data will be reported as a meta-analysis or a narrative report. ETHICS AND DISSEMINATION: No previous ethical approval is required for this publication since data used are already published. Results of this review will be disclosed via peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42021251842.

Existing predictive methods applied to gait analysis of patients with diabetes: study protocol for a systematic review.

INTRODUCTION: Type 2 diabetes can lead to gait abnormalities, including a longer stance phase, shorter steps and improper foot pressure distribution. Quantitative data from objective methods for evaluating gait patterns are accurate and cost-effective. In addition, it can also help predictive methods to forecast complications and develop early strategies to guide treatments. To date, no research has systematically summarised the predictive methods used to assess type 2 diabetic gait. Therefore, this protocol aims to identify which predictive methods have been employed to assess the diabetic gait. METHODS AND ANALYSIS: This protocol will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol (PRISMA-P) statement. Electronic searches of articles from inception to January 2022 will be performed, from May 2021 to 31 January 2022, in the Web of Science, MEDLINE, Embase, IEEE Xplore Digital Library, Scopus, CINAHL, Google Scholar, APA PsycInfo, the Cochrane Library and in references of key articles and grey literature without language restrictions. We will include studies that examined the development and/or validation of predictive methods to assess type 2 diabetic gait in adults aged >18 years without amputations, use of assistive devices, ulcers or neuropathic pain. Two independent reviewers will screen the included studies and extract the data using a customised charting form. A third reviewer will resolve any disagreements. A narrative synthesis will be performed for the included studies. Risk of bias and quality of evidence will be assessed using the Prediction Model Risk of Bias Assessment Tool and the Transparent Reporting of a multivariable prediction model for Individual Prognosis or Diagnosis. ETHICS AND DISSEMINATION: Ethical approval is not required because only available secondary published data will be analysed. The findings will be disseminated through peer-reviewed journals and/or presentations at relevant conferences and other media platforms. PROSPERO REGISTRATION NUMBER: CDR42020199495.

Rate of torque development of paretic lower limb is an excellent predictor of walking speed in chronic stroke individuals.

BACKGROUND: Walking speed discriminates levels of functionality in stroke survivors, but its relationship with neuromuscular parameters remains unclear. We aimed to (1) verify relationships between walking speed, peak torque, and rate of torque development in individuals with chronic stroke and (2) investigate whether adjusting the predictive model for assistive device use and lower limb motor function improves its accuracy. METHODS: Twenty-nine stroke survivors (time post-stroke ≥6 months) were assessed for walking speed, motor function, torque of knee extensors, and rate of torque development. Hierarchical multiple regression was conducted to infer the contribution of assistive device use and lower limb motor function in the proportion of variance in walking speed explained by neuromuscular parameters. Adequacy of regression models was verified using Shapiro-Wilk test and visual inspection of histograms. FINDINGS: Rate of torque development measures presented higher coefficients of determination (R2 = 0.399-0.457) than peak torque (R2 = 0.333). However, no differences were observed between correlation coefficients (P > 0.05). When adjusted for assistive device use and lower limb motor function, coefficients of determination of all neuromuscular parameters were improved (P < 0.05). Regression models showed good adequacy. INTERPRETATION: Peak torque and rate of torque development from knee extensors are adequate predictors of walking speed in stroke survivors. Adjusting predictive models for assistive device use and lower limb motor function increases predictive capacity. These findings may have repercussions for assessing chronic stroke individuals and developing treatment strategies.

Predictive factors of functional independence in basic activities of daily living during hospitalization and after discharge of stroke patients.

Objective: The aim of this study was to identify the predictive factors of functional independence in the basic activities of daily living during hospitalization, on the 10th and 28th day after stroke.Methods: A total of 433 patients (204 men and 229 women) took part. Functional independence data were collected using the Step 1 from an instrument called Stepwise. Analysis was conducted by logistic regression.Results: Due to the OR values below 1.0 we can verify that the age of 59 years or less and the presence of physiotherapy in the hospital were protective factors of functional independence. Other predictive factors were the number of stroke risk factors (bathing: OR = 0.4; p = .005, transfer: OR = 0.487; p = .025), the amount of medication used before stroke (bathing: OR = 1.7; p = .013), sex (grooming: OR = 1.6; p = .026); type of stroke (continence: OR = 2.2; p = .003-10th day; OR = 1.9; p = .013-28th day), previous strokes (eating: OR = 0.5; p = .036).Conclusions: According to the results, the risk of impaired functional independence decreased in bathing and eating and increased for dressing, grooming and transfer during clinical recovery suggesting the need for greater therapeutic intervention in different basic activities of daily living.

Effects of exergames training on postural balance in patients who had a chronic stroke: study protocol for a randomised controlled trial.

INTRODUCTION: Exergames training, as an additional therapy to standard care, has been widely used for motor recovery after patients who had a stroke, and it is a valuable and positive tool in the rehabilitation of this population. This study describes a single-blind randomised clinical trial that will aim to investigate the effects of exergames training on postural balance in patients with chronic stroke. METHODS AND ANALYSIS: Forty-two individuals with chronic stroke (>6 months), aged 20-75 years, will be randomised into two groups: the experimental group, which will be subjected to an exergames protocol, and control group, which will undergo a kinesiotherapy protocol. Both protocols are based on postural balance. The intervention will consist of 40-minute sessions two times per week for 10 consecutive weeks. The volunteers will be evaluated before the treatment, at the end of the interventions and 8 weeks thereafter. The primary outcome will be postural balance (Berg Balance Scale, Functional Reach Test, Timed Up and Go test and Centre of Pressure variables) and secondary outcomes will include gait (6 m timed walk and Kinovea Software), cortical activation patterns (electroencephalography Emotiv EPOC), functional independence (Functional Independence Measure), quality of life (Stroke-Specific Quality of Life Scale) and motivation (Intrinsic Motivation Inventory). ETHICS AND DISSEMINATION: This protocol was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (number 3.434.350). The results of the study will be disseminated to participants through social networks and will be submitted to a peer-reviewed journal and scientific meetings. TRIAL REGISTRATION NUMBER: Brazilian Registry of Clinical Trials (RBR-78v9hx).

Game therapy a new approach to treat women facing mixed urinary incontinence: A study protocol.

AIMS: To describe a pelvic floor muscle training (PFMT) isolated and associated with game therapy (PFMT + GT) for women facing mixed urinary incontinence (MUI) during climacteric period. METHODS: To standardize a randomized controlled clinical trial intervention, a protocol was created, in an attempt to decrease women's symptomatology generated by MUI, through pelvic floor and abdomino-loin-pelvic muscles strength, and endurance. This study protocol will be composed of 32 volunteers, divided into two groups of 16. They will perform PFMT isolated or PFMT + GT, twice a week during 8 weeks. Interventions will last 40 minutes and will be divided into warming (5 minutes), training (30 minutes), and 5 minutes will be composed of resting time between exercises (1 minute each). Isolated PFMT sessions will be performed through four modalities of exercises: diaphragmatic, bridge, abdominal (plank), and pelvic mobility. PFMT + GT training will be carried out by using Wii Fit Plus games, such as Lotus Focus, Penguin Slide, Basic Step, and Hula Hoop from Wii equipment. Assessments will occur before, after, and 1 month after interventions. Vaginal manometry, 1-hour Pad Test, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and Patient Global Intervention (PGI) will be used to evaluate the sample. CONCLUSIONS: It is expected greater increase on pelvic floor muscle (PFM) strength, endurance, vaginal pressure for PFMT + GG. Moreover, it is supposed that PFMT + GT volunteers present better treatment adherence due to games motivational inclusion.

Effects of Load Addition During Gait Training on Weight-Bearing and Temporal Asymmetry After Stroke: A Randomized Clinical Trial.

OBJECTIVE: The aim of the study was to evaluate the effects of adding load to restrain the nonparetic lower limb during gait training on weight-bearing and temporal asymmetry after stroke. DESIGN: Thirty-eight subjects were randomized into treadmill training with load (5% of body weight) on the nonparetic limb (experimental group) and treadmill training without load (control group). Interventions lasted 30 mins/d for 2 wks (9 sessions). Both groups performed home-based exercises and were instructed to increase the use of paretic limb in daily life situations. Ground reaction force was obtained by a force plate during standing position (static) and gait (dynamic). Temporal gait parameters were assessed by a motion system analysis. Outcome measures were evaluated at baseline, posttraining, and after a 40-day follow-up. RESULTS: The experimental group increased static ground reaction force of the paretic limb at posttraining (P = 0.037) and the control group increased dynamic ground reaction force of the paretic limb at posttraining (P = 0.021), both with maintenance at follow-up. Neither group showed a change in the swing time symmetry ratio after training (P = 0.190). CONCLUSIONS: Treadmill training associated with behavioral strategies/home-based exercises seemed to be useful to minimize weight-bearing asymmetry, but not to improve temporal gait asymmetry. Load addition did not show additional benefits.

Effects of motor imagery training of Parkinson's disease: a protocol for a randomized clinical trial.

BACKGROUND: Gait disorders in individuals with Parkinson's disease (PD) may be associated with alterations in the motor control system and aggravated by psychoemotional and cognitive issues. Therapeutic strategies aimed at self-perception and motor regulation seem to be promising. Motor imagery (MI) has been shown to be one of these strategies, but there is still no clear evidence of its applicability in this population. The aim of this trial is to determine the effects of motor-imagery training on the gait and electroencephalographic activity of individuals with PD. METHODS/DESIGN: The sample will consist of 40 individuals, aged between 45 and 75 years, in the mild and moderate phase of the disease, with the ability to generate voluntary mental images. They will be assessed for cognitive level, degree of physical disability, mental-image clarity, kinematic gait variables, electroencephalographic activity and mobility. Next, subjects will be randomly assigned to an experimental group (EG) and a control group (CG). The EG will perform motor imagery and gait, while the CG will only engage in gait exercises. Twelve training sessions will be conducted lasting up to 90 min each, three times a week, for 4 weeks. The subjects will be reassessed on the kinematic variables of gait, electroencephalographic activity and mobility at 1, 7 and 30 days after the final training session. DISCUSSION: The results may provide an important advance in neurological rehabilitation where an easy-access and low-cost intervention may help to improve gait, electroencephalographic activity and mobility in individuals with PD.

Effects of inclined treadmill training on functional and cardiovascular parameters of stroke patients: study protocol for a randomized controlled trial.

BACKGROUND: Treadmill training has been widely used for gait recovery after stroke. Gait re-establishment is one of the main objectives of rehabilitation programs after stroke, aiming to acquire more functional patterns and increase walking speed, along with improvement in cardiovascular function. The aim of this study is to evaluate the effects of a treadmill gait training protocol on functional and cardiovascular variables in patients with chronic stroke. METHODS: A single-blind randomized clinical trial will be conducted. The sample will consist of 36 patients, who will be allocated in three groups: control group (n = 12), experimental group 1 (n = 12), and experimental group 2 (n = 12). The intervention will occur for 6 consecutive weeks, three times a week, 30 min each session, in all groups. The control group will perform a treadmill gait training without inclination, experimental group 1 will perform a treadmill gait training with anterior inclination of 5%, and experimental group 2 will perform a treadmill gait training with anterior inclination of 10%. All participants will be assessed for sample characterization measures, gait speed, functional capacity, systemic arterial blood pressure, heart rate, peripheral oxygen saturation, exercise capacity, neuromuscular torque, and quality of life. Evaluations of outcome measures will occur at the end of the interventions (post-training) and after 1 month and 1 year after the end of the interventions (short- and long-term follow-up). Statistical analysis will be performed descriptively and inferentially. Alpha equals 5% will be considered for inferential analysis. Mixed analysis of variance with repeated measures will be used to compare outcome measures between groups and between baseline, post-training, and follow-up. Normality test (Shapiro-Wilk) and subsequently t test (or Mann-Whitney) will be used to compare groups during the same training session. DISCUSSION: It is believed that treadmill training, especially treadmill training with anterior inclination, may result in improved exercise capacity in patients with stroke, reduced blood pressure and heart rate values, and an improvement in functional parameters with increased gait speed, functional capacity, quadriceps muscle torque, and quality of life.

Effects of constraint-induced movement therapy for lower limbs on measurements of functional mobility and postural balance in subjects with stroke: a randomized controlled trial.

Abstrato Background: Constraint-induced movement therapy (CIMT) is suggested to reduce functional asymmetry between the upper limbs after stroke. However, there are few studies about CIMT for lower limbs. OBJECTIVE: To examine the effects of CIMT for lower limbs on functional mobility and postural balance in subjects with stroke. METHODS: A 40-day follow-up, single-blind randomized controlled trial was performed with 38 subacute stroke patients (mean of 4.5 months post-stroke). Participants were randomized into: treadmill training with load to restraint the non-paretic ankle (experimental group) or treadmill training without load (control group). Both groups performing daily training for two consecutive weeks (nine sessions) and performed home-based exercises during this period. As outcome measures, postural balance (Berg Balance Scale - BBS) and functional mobility (Timed Up and Go test - TUG and kinematic parameters of turning - Qualisys System of movement analysis) were obtained at baseline, mid-training, post-training and follow-up. RESULTS: Repeated-measures ANOVA showed improvements after training in postural balance (BBS: F = 39.39, P < .001) and functional mobility, showed by TUG (F = 18.33, P < .001) and by kinematic turning parameters (turn speed: F = 35.13, P < .001; stride length: F = 29.71, P < .001; stride time: F = 13.42, P < .001). All these improvements were observed in both groups and maintained in follow-up. CONCLUSIONS: These results suggest that two weeks of treadmill gait training associated to home-based exercises can be effective to improve postural balance and functional mobility in subacute stroke patients. However, the load addition was not a differential factor in intervention.
