Mobility, functionality and functional mobility: A review and application for canine veterinary patients. Vet J 2024; 305:106123. [PMID: 38642699 DOI: 10.1016/j.tvjl.2024.106123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 04/15/2024] [Accepted: 04/16/2024] [Indexed: 04/22/2024]
Abstract
Mobility is an essential aspect of a dog's daily life. It is defined as the ability to move freely and easily and deviations from an animals' normal mobility capabilities are often an indicator of disease, injury or pain. When a dog's mobility is compromised, often functionality (ability to perform activities of daily living [ADL]), is also impeded, which can diminish an animal's quality of life. Given this, it is necessary to understand the extent to which conditions impact a dog's physiological ability to move around their environment to carry out ADL, a concept termed functional mobility. In contrast to human medicine, validated measures of canine functional mobility are currently limited. The aim of this review is to summarise the extent to which canine mobility and functionality are associated with various diseases and how mobility and functional mobility are currently assessed within veterinary medicine. Future work should focus on developing a standardised method of assessing functional mobility in dogs, which can contextualise how a wide range of conditions impact a dog's daily life. However, for a true functional mobility assessment to be developed, a greater understanding of what activities dogs do on a daily basis and movements underpinning these activities must first be established.

Parallel-Forms Reliability and Minimal Detectable Change of the Four Telerehabilitation Version Mobility-Related Function Scales in Stroke Survivors. Arch Phys Med Rehabil 2024:S0003-9993(24)00059-5. [PMID: 38307318 DOI: 10.1016/j.apmr.2024.01.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 11/25/2023] [Accepted: 01/15/2024] [Indexed: 02/04/2024]
Abstract
OBJECTIVE To investigate the parallel-forms reliability, minimal detectable change with 95% confidence interval (MDC95), and feasibility of the 4 telerehabilitation version mobility-related function scales: Fugl-Meyer Assessment-lower extremity subscale (Tele-FMA-LE), Berg Balance Scale (Tele-BBS), Tinetti Performance Oriented Mobility Assessment-Gait subscale (Tele-POMA-G), and Rivermead Mobility Index (Tele-RMI). DESIGN Reliability and agreement study and cross-sectional study. SETTING Medical center. PARTICIPANTS Stroke survivors' ability to independently walk 3 meters with assistive devices, age of ≥18 years for participants and their partners, stable physical condition, and absence of cognitive impairment (N=60). INTERVENTIONS Not applicable. MAIN OUTCOMES MEASURES Parallel-forms reliability and MDC95 of Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI. RESULTS No significant differences (P>.05) were observed among the mean scores of the telerehabilitation version and face-to-face version mobility-related function scales. Intraclass correlation coefficients (ICCs) indicated good reliability for most scales, with Tele-FMA-LE, Tele-BBS, and Tele-RMI scores achieving values of 0.81, 0.78, and 0.84. Tele-POMA-G scores demonstrated moderate reliability (ICC=0.72). Weighted kappa (κw) showed good-to-excellent reliability for most individual items (κw>0.60). The MDCs of the Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI were 5.84, 8.10, 2.74, and 1.31, respectively. Bland-Altman analysis showed adequate agreement between tele-assessment and face-to-face assessment for all scales. The 5 dimensions affirm the robust feasibility of tele-assessment: assessment time, subjective fatigue perception, overall preference, participant satisfaction, and system usability. CONCLUSIONS The study demonstrates good parallel-forms reliability, MDC, and promising feasibility of the 4 telerehabilitation version mobility-related function scales (Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI) in survivors of stroke.

Abstract
BACKGROUND Turning may be particularly challenging for stroke patients leading to decreased mobility and increased functional restriction. Timed up and go instrumentation using a simple technology in the clinical context could allow for the collection of both traditional and potentially more discriminatory variables in turning ability. AIM Determine whether the speed turning metrics obtained by a single inertial sensor are suitable for differentiating between stroke patients with varying levels of mobility and disability. DESIGN Cross-sectional study. SETTING Outpatients setting. POPULATION Chronic stroke patients. METHODS A total of 48 chronic stroke patients and 23 healthy controls were included. Stroke patients were divided in two groups based on the total iTUG score: an impaired mobility (> 20 seconds) and an available mobility (<20 seconds) group. All subjects performed an instrumented Timed Up and Go (iTUG) wearing a single IMU sensor on the lower back. Time of subcomponents of the timed up and go test and kinematic parameters of turning were quantified. Other clinical outcomes were: 10 meters walk test, Functional Ambulation Categories Scale (FAC), the Rivermead Mobility Index (RMI), Modified Rankin Scale and the Saltin-Grimby Physical Activity Level Scale (SGPALS). RESULTS There were significant differences (P<0.01) in iTUG phases and turning speeds among groups. Low to strong significant correlations were found between measures derived from the turning speeds and clinical measures. The area under the curve (AUC) of Receiver Operating Characteristic (ROC) turning speeds was demonstrated to be able to discriminate (AUC: 0.742-0.912) from available to impaired stroke patients. CONCLUSIONS This study provides evidence that turning speeds during timed up and go test are accurate measures of mobility and capable of discriminating stroke patients with impaired mobility from those with normal mobility. CLINICAL REHABILITATION IMPACT The turning metrics are related to impairment and mobility in chronic stroke patients; hence they are important to include during clinical evaluation and may assist in creating a customized strategy, assess potential treatments, and effectively organize recovery.

Association between participation self-efficacy and participation in stroke survivors. BMC Neurol 2022; 22:361. [PMID: 36138370 PMCID: PMC9494797 DOI: 10.1186/s12883-022-02883-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 05/10/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Most stroke survivors face restrictions in functional disability and social participation, which can impede their recovery and community reintegration. Participation self-efficacy refers to survivors' confidence in using strategies to manage participation in areas including community living and work engagement. This study aimed to assess the association between participation self-efficacy and participation among stroke survivors. METHODS This study adopted a cross-sectional correlational design with a convenience sample of 336 stroke survivors recruited from five hospitals in China. Participation self-efficacy was measured using the Chinese version of the Participation Strategies Self-Efficacy Scale (PS-SES-C) and participation measured using the Chinese version of the Reintegration to Normal Living Index (RNLI-C). The association between participation self-efficacy and participation was examined using multiple regression analysis with adjustment for potential confounders. RESULTS Participants had a mean age of 69.9 ± 11.5 years, with most (81.6%) having an ischaemic stroke, and more than half (61.6%) a first-ever stroke. After adjustment for potential confounders, every 10-point increase in the PS-SES-C total score was significantly associated with an average 1.3-point increase in the RNLI-C total score (B = 1.313, SE = 0.196, p < 0.001). CONCLUSIONS This study demonstrates that participation self-efficacy is significantly associated with participation among Chinese community-dwelling survivors of a mild or moderate stroke. This suggests that rehabilitation programmes for stroke survivors may be more effective if they incorporate participation-focused strategies designed to enhance self-efficacy. (229 words).

Abstract
INTRODUCTION Studies show that stroke survivors encounter physical and psychological limitations that restrict their participation in social and community activities. Systematic reviews have yielded inconclusive evidence regarding the effectiveness of different interventions intended to support stroke survivors' social participation. Recent advances in virtual reality technology may offer promising solutions, although the optimal approach to enhance social participation among stroke survivors is yet to be determined. This trial aims to develop and evaluate the effectiveness of a social participation-focused virtual reality (SP-VR) intervention on the physical, psychological and social outcomes of community-dwelling stroke survivors with physical disabilities. METHODS AND ANALYSIS A two-arm randomised, controlled, assessor-blind clinical trial will be conducted with 250 stroke survivor-caregiver dyads recruited from three acute and one rehabilitation hospitals, and three stroke nurse-led clinics. Participants will be survivors of a first or recurrent stroke within 6 months of stroke onset and able to remain in a sitting position without support, and their primary caregivers. Eligible participants will be randomly allocated to receive the SP-VR intervention or usual care which includes conventional physical therapy services. The intervention group will receive a newly developed 6-week novel custom-made SP-VR application comprising two sessions weekly. Three SP-VR modules will cover key aspects of survivors' social health needs, namely functional rehabilitation, social participation, and social interaction and recreation. The primary outcome for stroke survivors is social participation, and secondary outcomes include depressive symptoms, participation self-efficacy, physical function, functional mobility and social support. User satisfaction will be evaluated among both survivors and caregivers. Data will be collected in person at baseline, immediately after, and 3 months postintervention. ETHICS AND DISSEMINATION Ethical approval has been obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Research Ethics Committee (Ref. No.: 2019.676). Study results will be disseminated through peer-reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER ChiCTR2100050850.

Abstract
Brain network analysis can offer useful information to guide the rehabilitation of post-stroke patients. We applied functional network connection models based on multiplex-multilayer network analysis (MMN) to explore functional network connectivity changes induced by robot-aided gait training (RAGT) using the Ekso, a wearable exoskeleton, and compared it to conventional overground gait training (COGT) in chronic stroke patients. We extracted the coreness of individual nodes at multiple locations in the brain from EEG recordings obtained before and after gait training in a resting state. We found that patients provided with RAGT achieved a greater motor function recovery than those receiving COGT. This difference in clinical outcome was paralleled by greater changes in connectivity patterns among different brain areas central to motor programming and execution, as well as a recruitment of other areas beyond the sensorimotor cortices and at multiple frequency ranges, contemporarily. The magnitude of these changes correlated with motor function recovery chances. Our data suggest that the use of RAGT as an add-on treatment to COGT may provide post-stroke patients with a greater modification of the functional brain network impairment following a stroke. This might have potential clinical implications if confirmed in large clinical trials.

A Co-creation Centre for Accessible Rehabilitation Technology. FRONTIERS IN REHABILITATION SCIENCES 2022; 2:820929. [PMID: 36188853 PMCID: PMC9397706 DOI: 10.3389/fresc.2021.820929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 12/13/2021] [Indexed: 12/02/2022]
Abstract
Background: The prevalence of disabling conditions is increasing globally. Rehabilitation improves function and quality of life across many conditions, particularly when applied intensively. The limited workforce, however, cannot deliver evidence-based intensive rehabilitation. By providing individuals with the tools for self- rehabilitation, technology helps bridge the gap between evidence and practise. Few people, however, can access rehabilitation technology. Barriers such as cost, training, education, portability and poor design stand in the way of equitable access. Our group of engineers and researchers have established a centre dedicated to developing accessible technology through close, frequent engagement with users and industry. Methods: The centre employs a co-creation model, coupling engineering and science with user experience and industrial partnerships to develop accessible technology and associated processes. Due to the complexity and size of the challenge the initial focus is stroke. Recruited through a medical charity, participants, with a wide range of disabilities, use prototype and commercial technology during an 8-week rehabilitation programme with supervision from health professionals. The centre includes de-weighting systems, neurostimulation, virtual reality, treadmills, bespoke rehab games, communication apps, powered exercise equipment and gamified resistance equipment. Standard outcome measures (International Classification of Functioning, Disability and Health) are recorded before, during, immediately after, and 3 months after the intervention and used in combination with an interview to design the initial rehabilitation programme, which is reviewed fortnightly. Qualitative methods (surveys and interviews) are used to capture personal experiences of the programme and individual technology and an advisory group of stroke survivors help interpret outcomes to feed into the technology design process. Ethical approval has been granted for a pilot cohort study with stroke survivors, which is currently underway (01/09/2021–31/12/2021) investigating acceptability and feasibility, due to report findings in 2022. Discussion: Through partnerships, research collaborations and a co-creation model a new centre dedicated to the development of accessible rehabilitation technology has been launched and currently undergoing acceptability and feasibility testing with stroke survivors. The centre, through its close engagement with users and industry, has the potential to transform the way rehabilitation technology is developed and help revolutionise the way rehabilitation is delivered.

Abstract
BACKGROUND SUBAR is a new ground walking exoskeletal robot. The objective of this study is to investigate SUBAR-assisted gait training's effects in patients with chronic stroke. METHODS This preliminary study is a prospective randomized controlled trial. Thirty adults were enrolled 6 months after the onset of stroke with functional ambulation category scores ≥ 3. Patients were randomly assigned to receive robot-assisted gait training (SUBAR group, n = 15) or conventional physiotherapy (control group, n = 15). All patients received a total of 10 treatment sessions of 30 minutes each for 3 weeks. Before and after the 10-treatment sessions, patients were evaluated. The primary outcome is the 10 meter walk test and the secondary outcomes were the functional ambulation category scale, the Motricity Index-Lower, Modified Ashworth Scale (MAS), timed up and go, Rivermead Mobility Index, Berg Balance Scale (BBS), and gait analysis. RESULTS In the SUBAR group, MAS and step length were significantly improved between pre- and posttreatment measurements (Δmean ± SD: -1.1 ± 1.6 and 5.5 ± 7.6, P = .019 and .016, respectively). The SUBAR group improved the stride length and step length of the affected limb but not significantly. The control group had significant improvements in the BBS, MAS, and stride length between pre- and posttreatment measurements (Δmean ± SD: 3.5 ± 4.6, -0.8 ± 1.5, and 6.5 ± 9.5; P = .004, .031, and .035, respectively). The BBS improved more in the control group than in the SUBAR group. There were no other differences between the SUBAR group and the control group. CONCLUSION Our results suggest that SUBAR-assisted gait training improved gait parameters in patients with chronic stroke. However, there was no significant difference in most outcome measures compared to conventional physiotherapy. Further research is warranted to measure the effects of SUBAR-assisted gait training.

Factors Associated with Post-Stroke Depression in Chinese Stroke Survivors. J Stroke Cerebrovasc Dis 2021; 30:106076. [PMID: 34507255 DOI: 10.1016/j.jstrokecerebrovasdis.2021.106076] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 08/05/2021] [Accepted: 08/16/2021] [Indexed: 11/24/2022] Open
Abstract
OBJECTIVES To explore the relationship between participation self-efficacy, sociodemographic and clinical characteristics, and post-stroke depression in stroke survivors and provide insights into the development of rehabilitation programmes. MATERIALS AND METHODS A cross-sectional descriptive study was conducted with 336 participants recruited from five hospitals in Kunming, China. Measures included the Chinese version of the Participation Strategies Self-Efficacy Scale (PS-SES-C), Geriatric Depression Scale (GDS), modified Barthel Index, Rivermead Mobility Index (RMI), Reintegration to Normal Living Index (RNLI), and the Social Support Questionnaire (SSQ6). Logistic regression analyses were performed using SPSS 25.0. RESULTS Nearly half (44.6%) of the sample was found to have depression. The mean participation self-efficacy score of stroke survivors with depression was significantly lower than that of those without depression. Logistic regression analyses suggested that participation self-efficacy is a constant and major factor negatively associated with depression, with every 10-pt increase in the PS-SES-C score associated with decreased odds of depression (p<0.001). Other features associated with depression prevalence to varying degrees included education level, marital status, pre-morbid financial role in family, stroke symptom severity, history of heart disease, frequency of stroke, lesion side, stroke type, and use of assistive aids. CONCLUSIONS Participation self-efficacy is negatively associated with depression in stroke survivors. Rehabilitation programmes might consider incorporating interventions aimed at boosting participation self-efficacy in order to promote positive recovery outcomes among survivors.

Abstract
BACKGROUND Mobility is a major determinant of social participation after stroke and the relationship between the two may be mediated by participation self-efficacy. OBJECTIVE To investigate the hypothesis that participation self-efficacy mediates the association between mobility and social participation among stroke survivors. METHODS A secondary data analysis of a cross-sectional study aiming to validate the Chinese version of the Participation Strategies Self-Efficacy Scale was conducted. Three hundred and thirty-six stroke survivors were recruited. With mobility as the predictor variable and social participation as the outcome, path analysis was utilized to assess the mediating effect of participation self-efficacy on the association between the two factors. RESULTS Mobility was significantly associated with social participation (B=2.773, p<0.001) and participation self-efficacy (B=6.060, p<0.001). After adjusting for mobility, participation self-efficacy was significantly associated with social participation. The association between mobility and social participation was mediated by participation self-efficacy. CONCLUSIONS When aiming to improve stroke survivor community reintegration, interventions targeted at boosting participation self-efficacy must be considered given its beneficial mediatory effect on mobility and social participation.

Characteristics of rectus femoris activation and rectus femoris-hamstrings coactivation during force-matching isometric knee extension in subacute stroke. Exp Brain Res 2021; 239:2621-2633.

Abstract
The spectral properties of surface electromyographic (EMG) signal in the rectus femoris (RF) and the coactivation in the medial hamstrings (MH) were investigated in 45 stroke subjects (22 ± 12 days post-onset) and 30 age-matched healthy controls who performed unilateral knee extensions at maximum effort (100% MVC) and during 5-s force-matching tasks (10, 30, 50% MVC). The spectral properties were obtained through a power spectrum analysis based on Fast Fourier Transform. The coactivation was measured as the MH amplitude (%max) and MH/RF amplitude ratio. Force variability was expressed as the coefficient of variation. Both knee extensors and flexors were weaker in the paretic leg than the non-paretic and control legs (p < 0.001). A significantly higher relative power in the 5-13 and 13-30 Hz bands was found in the paretic than the non-paretic leg across all force levels (p ≤ 0.001) without changes in the 30-60 and 60-100 Hz bands or the mean and median frequencies. Regarding the antagonist coactivation, MH amplitude in the paretic leg was higher than in the non-paretic leg (submaximal levels, p < 0.0001) and the control leg (all force levels, p = 0.0005) with no differences between legs in the MH/RF ratio. The steadiness of the knee extension force was not related to the spectral properties of the agonist EMG or antagonistic coactivation. Greater coactivation was associated with weaker paretic knee flexors (p ≤ 0.0002). The overall results suggest variably altered agonist activation and antagonistic coactivation over the range of isometric knee extension contractions in subacute stroke.

Abstract
PURPOSE To examine the psychometric properties of a Chinese version of the Participation Strategies Self-Efficacy Scale (PS-SES) among stroke survivors. METHODS The PS-SES was translated into Chinese. A cross-sectional descriptive study was conducted with 336 stroke survivors recruited from the neurology departments of five hospitals in China. Reliability, concurrent validity, and construct validity of the scale were determined. RESULTS The Chinese version of the PS-SES (PS-SES-C) showed good internal consistency and test-retest reliability, with a Cronbach's α of 0.98 and an intraclass correlation coefficient of 0.79. There was a moderate to strong positive correlation between the PS-SES-C and Chinese version of the General Self-Efficacy Scale (r = 0.59, p < .001), positive correlations between the PS-SES-C and Chinese versions of the Modified Barthel Index (r = 0.59, p < .001), Rivermead Mobility Index (r = 0.70, p < .001), and Reintegration to Normal Living Index (r = 0.70, p < .001), and a negative correlation between the PS-SES-C and National Institutes of Health Stroke Scale (r = -0.63, p < .001). Known-group validity and factorial validity were also supported. CONCLUSIONS The PS-SES-C is a reliable and valid instrument for assessing self-efficacy in managing the participation of Chinese stroke survivors.Implications for rehabilitationSelf-efficacy significantly predicts activity and participation in stroke survivors and is a major outcome measure in many stroke rehabilitation programmes.The translated Chinese version of the Participation Strategies Self-efficacy Scale is a valid and reliable tool to evaluate stroke survivors' self-efficacy in managing participation.The Chinese version of the Participation Strategies Self-efficacy Scale can be used to assess stroke recovery among the Chinese population in clinical and research settings.

Abstract
BACKGROUND Many studies have demonstrated positive effects of virtual reality (VR) and robot-assisted gait training (RAGT) on balance, gait skills, functional capacity, active participation, and motivation in stroke patients, previously. However, the effects of VR augmented RAGT on dual-task performance which requires simultaneous use of motor and cognitive parameters have not been investigated. AIM To primarily investigate the effects of virtual reality (VR) augmented robot-assisted gait training (RAGT) on dual-task performance and secondarily, functional measurements in chronic stroke patients. DESIGN A randomized, single-blind trial. SETTING Inpatient rehabilitation center. POPULATION The study included 30 chronic stroke patients aged between 40-65 with the level of ≥3 from Functional Ambulation Classification and ≥24 from the Standardized Mini Mental State Examination. METHODS Fifteen patients in the study group received VR augmented RAGT and 15 patients in the control group received only RAGT during 12 sessions (six weeks). All patients received neurodevelopmental therapy in addition to their treatments, simultaneously. To evaluate dual-task performance, motor and cognitive tasks were given in addition to the 10 Meter Walk (first motor task), and durations were recorded in seconds. Functional measures such as Functional Gait Assessment, Rivermead Mobility Index, Berg Balance Scale, Fall Activity Scale International, and the Functional Independence Measure for gait, mobility, balance, fear of falling, and independence in daily living activities were also applied, consecutively. RESULTS The mean age of the study population was 57.93±5.91. After the treatment, single and dual-task gait speeds and cognitive dual-task performance increased in the study group (P<0.05), while no change was observed in the control group (P>0.05). No significant difference was detected between the groups in terms of all assessments after the treatment (P>0.05). CONCLUSIONS This study demonstrated that VR augmented RAGT improved dual-task gait speeds and dual-task performance of chronic stroke patients; however, there were no difference between the two groups after the treatment. Although functional improvements were determined with VR combined RAGT approach, it was not superior to RAGT only treatment. CLINICAL REHABILITATION IMPACT The results of current study suggest the simultaneous use of VR as an adjunct therapy method to the functional training to obtain functional gains in ambulant patients with chronic stroke.

Abstract
OBJECTIVE To compare oxygen consumption and energy expenditure (EE) of the activities of daily living (ADL) in people with multiple sclerosis (PwMS) and healthy subjects. DESIGN Cross-sectional observational study. SETTING Outpatient care facilities. PARTICIPANTS Twenty-four moderately impaired PwMS and 21 healthy controls (N=45). INTERVENTION Not applicable. MAIN OUTCOME MEASURES Oxygen consumption, EE rate, and total EE assessed by portable open-circuit spirometry during the accomplishment of a comprehensive set of 14 ADL. Body composition was also assessed with bioelectrical impedance analysis. Body cell mass was used to normalize metabolic rates between groups. RESULTS PwMS exhibited significantly higher oxygen consumption than controls in transfer and mobility tasks (walking with stairs: +10.4%, P=.04; without stairs: +15.2%, P=.002; driving: +10.4%, P=.04) and higher EE rates for walking (+13.6%, P=.01). ADL completion took significantly longer in PwMS. Consequently, when total EE to complete each ADL was considered, PwMS used significantly more energy in 10 of the 14 ADL. Of these, "climb stairs" and walking with or without stairs showed the largest differences (+100%, +99.5%, +79.3%, respectively; all P values<.0005), followed by "dressing" (+48.8%; P=.002), "laundry" (+41.7%; P=.007), and "shopping" (+40.1%; P=.003). CONCLUSIONS Moderately disabled PwMS display oxygen consumption and EE rates during ADL that are comparable to those of matched healthy subjects, except for the activities that involve walking. Although metabolic rates were not different for the majority of ADL, PwMS showed higher total EE to complete the same activities at a comparable work intensity, which may contribute to the burden of "real-life" tiredness and fatigue typically described in this population. Importantly, the subjective Modified Fatigue Impact Scale score significantly correlated to EE and oxygen consumption of selected ADL, such as "make a bed," "driving," "clean surfaces," and "climb stairs." The joint employment of open-circuit spirometry during ADL and body composition analysis allows an accurate metabolic characterization of PwMS, who frequently complain of fatigue.

Treadmill training augmented with real-time visualisation feedback and function electrical stimulation for gait rehabilitation after stroke: a feasibility study. BMC Biomed Eng 2020; 1:20. [PMID: 32903355 PMCID: PMC7422553 DOI: 10.1186/s42490-019-0020-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Accepted: 07/11/2019] [Indexed: 11/16/2022] Open
Abstract
Background Stroke rehabilitation often uses the motor relearning concept that require patients to perform active practice of skill-specific training and to receive feedback. Treadmill training augmented with real-time visualisation feedback and functional electrical stimulation may have a beneficial synergistic effect on motor recovery. This study aims to determine the feasibility of this kind of enhanced treadmill training for gait rehabilitation among patients after stroke. A system for dynamic visualisation of lower-limb movement based on 3-dimentional motion capture and a computer timed functional electrical stimulation system was developed. Participants received up to 20-min enhanced treadmill training instead of their over-ground gait training once or twice a week for 6 weeks at Coathill hospital, Lanarkshire, United Kingdom. Number of training sessions attended, and training duration were used to assess feasibility. Ankle kinematics in the sagittal plane of walking with and without functional electrical stimulation support of the pre-tibial muscles were also compared and used to confirm the functional electrical stimulation was triggered at the targeted time. Results Six patients after stroke participated in the study. The majority of participants were male (5/6) with a age range from 30 to 84 years and 4/6 had left hemiplegia. All participants suffered from brain infarction and were at least 3 months after stroke. Number of training sessions attended ranged from 5 to 12. The duration of training sessions ranged from 11 to 20 min. No serious adverse events were reported. The computerised functional electrical stimulation to the pre-tibial muscles was able to reduce plantarflexion angle during the swing phase with statistical significance (p = 0.015 at 80%; p = 0.008 at 90 and 100% of the gait cycle). Conclusions It is safe and feasible to use treadmill gait training augmented with real-time visual feedback and computer-controlled functional electrical stimulation with patients after stroke in routine clinical practice. Trial registration NCT03348215. Registered 20 November 2017.

Abstract
Introduction: The de Morton Mobility Index (DEMMI) is a unidimensional clinical instrument proven reliable and valid for measuring mobility in the elderly, but its responsiveness has not been evaluated when applying the methodology recommended by COSMIN.Purpose: To evaluate the responsiveness and the predictive validity of the DEMMI.Materials and methods: Elderly people, referred for municipality-based rehabilitation, were consecutively included. Eight hypotheses regarding the relationship between the change scores in the DEMMI and other functional measures of mobility were tested by assessing the participants before and after rehabilitation. Three months after completing the rehabilitation, the participants' functional status was evaluated.Results: 250 elderly people (mean age 85 years, 63% women) were included. The change scores in the DEMMI and the other measures correlated (r = 0.422 to 0.547), but only three out of the eight hypotheses were confirmed. A DEMMI score of less than 48 and less than 67 can predict inability of ambulating close to the participant's residence and using public transport, respectively.Conclusions: We found a moderate responsiveness and a high predictive validity of the DEMMI score. The DEMMI appears to be an appropriate instrument for monitoring change in mobility and predicting functional status among elderly patients undergoing rehabilitation.Implications for rehabilitationThe de Morton Mobility Index (DEMMI) is a clinical instrument for measuring mobility.This study shows that the DEMMI was responsive to change in mobility and predicted disability among a diverse group of elderly individuals referred to rehabilitation after hospital discharge.The DEMMI is applicable as an outcome measure in trials investigating the effect of rehabilitation and for clinical decision-making concerning geriatric rehabilitation.

Abstract
BACKGROUND The benefits of engaging informal carers or family in the delivery of therapy intervention for people with stroke have not been well researched. OBJECTIVES To assess the effectiveness of a home-based carer-assisted in comparison to hospital-based therapist-delivered therapy for community-dwelling stroke survivors. METHODS An assessor blinded randomised controlled trial was conducted on 91 stroke survivors (mean age 58.9±10.6 years, median time post-onset 13.0 months, 76.5% males) who had completed individual rehabilitation. The control group received hospital-based group therapy delivered by physiotherapists as out-patients and the test group was assigned to a home-based carer-assisted therapy. Targeted primary outcomes were physical functions (mobility, balance, lower limb strength and gait speed). A secondary outcome index was health-related quality of life. An intention-to-treat analysis was used to evaluate outcomes at week 12 of intervention. RESULTS Both therapy groups improved significantly in all the functional measures; mobility (p < 0.01), balance (p < 0.01), lower limb strength (p < 0.01), gait speed (p < 0.05), and in the quality of life score (p < 0.05) at trial completion. No statistical differences were found between the two groups in any outcome indices (all p > 0.05). CONCLUSIONS The home-based carer-assisted therapy is as effective as the hospital-based therapist-delivered training in improving post-stroke functions and quality of life.

Abstract
PURPOSE The aim of this study is to evaluate the properties of the Leg Activity measure according to COnsensus-based Standards for the selection of health Measurement INstruments. METHOD Participants were assessed at baseline, one day, 6 weeks and 12 weeks, following treatment for leg spasticity with botulinum toxin and physical interventions. RESULTS In stage 1, 64 participants were recruited to evaluate the initial psychometric properties of Leg Activity measure. In stage 2, 100 additional participants were recruited, to evaluate the scaling properties. Total sample of 164 participants was used. Construct validity was supported for "passive function", "active function" and "impact on quality of life". Cronbach's alpha was 0.86, 0.97 and 0.87 respectively for the scales. Item level test-retest agreement ranged from 91-97% (Kappa 0.75-0.95). Following treatment for spasticity (n = 64), the Leg Activity measure "passive function" and "impact on life" scales were responsive to change. Principal components analysis confirmed the constructs and a unidimensional Rasch Partial Credit Model was subsequently established for each scale. Transformation to an interval scale was achieved. Using the ordinal-to-interval conversion tables, parametric statistical analysis may be used. CONCLUSION The study provides support for the Leg Activity measure being valid, reliable and responsive.Implications for rehabilitationThe Leg Activity measure is the only published self-report measure in the current literature that addresses passive and active function as well as impact on quality of life, of the paretic leg in a comprehensive manner.The initial evaluation of Leg Activity measure psychometric properties, in relation to the COnsensus-based Standards for the selection of health Measurement INstruments checklist and Medical Outcomes Trust Quality Criteria, supports its measurement properties for clinical and research use.The Leg Activity measure as a valid, reliable and responsive tool for the evaluation of treatment in leg spasticity including condition specific (spasticity) quality-of-life.

Abstract
OBJECTIVES: To investigate immediate changes in walking performance associated with three implicit motor learning strategies and to explore patient experiences of each strategy. DESIGN: Participants were randomly allocated to one of three implicit motor learning strategies. Within-group comparisons of spatiotemporal parameters at baseline and post strategy were performed. SETTING: Laboratory setting. SUBJECTS: A total of 56 community-dwelling post-stroke individuals. INTERVENTIONS: Implicit learning strategies were analogy instructions, environmental constraints and action observation. Different analogy instructions and environmental constraints were used to facilitate specific gait parameters. Within action observation, only videotaped gait was shown. MAIN MEASURES: Spatiotemporal measures (speed, step length, step width, step height) were recorded using Vicon 3D motion analysis. Patient experiences were assessed by questionnaire. RESULTS: At a group level, three of the four analogy instructions ( n = 19) led to small but significant changes in speed ( d = 0.088 m/s), step height (affected side d = 0.006 m) and step width ( d = -0.019 m), and one environmental constraint ( n = 17) led to significant changes in step width ( d = -0.040 m). At an individual level, results showed wide variation in the magnitude of changes. Within action observation ( n = 20), no significant changes were found. Overall, participants found it easy to use the different strategies and experienced some changes in their walking performance. CONCLUSION: Analogy instructions and environmental constraints can lead to specific, immediate changes in the walking performance and were in general experienced as feasible by the participants. However, the response of an individual patient may vary quite considerably.

Abstract
OBJECTIVES To assess acceptability and feasibility of trial processes and the Rehabilitation Training (ReTrain) intervention including an assessment of intervention fidelity. DESIGN A two-group, assessor-blinded, randomised controlled trial with parallel mixed methods process and economic evaluations. SETTING Community settings across two sites in Devon. PARTICIPANTS Eligible participants were: 18 years old or over, with a diagnosis of stroke and with self-reported mobility issues, no contraindications to physical activity, discharged from National Health Service or any other formal rehabilitation programme at least 1 month before, willing to be randomised to either control or ReTrain and attend the training venue, possessing cognitive capacity and communication ability sufficient to participate. Participants were individually randomised (1:1) via a computer-generated randomisation sequence minimised for time since stroke and level of functional disability. Only outcome assessors independent of the research team were blinded to group allocation. INTERVENTIONS ReTrain comprised (1) an introductory one-to-one session; (2) ten, twice-weekly group classes with up to two trainers and eight clients; (3) a closing one-to-one session, followed by three drop-in sessions over the subsequent 3 months. Participants received a bespoke home-based training programme. All participants received treatment as usual. The control group received an exercise after stroke advice booklet. OUTCOME MEASURES Candidate primary outcomes included functional mobility and physical activity. RESULTS Forty-five participants were randomised (ReTrain=23; Control=22); data were available from 40 participants at 6 months of follow-up (ReTrain=21; Control=19) and 41 at 9 months of follow-up (ReTrain=21; Control=20). We demonstrated ability to recruit and retain participants. Participants were not burdened by the requirements of the study. We were able to calculate sample estimates for candidate primary outcomes and test procedures for process and health economic evaluations. CONCLUSIONS All objectives were fulfilled and indicated that a definitive trial of ReTrain is feasible and acceptable. TRIAL REGISTRATION NUMBER NCT02429180; Results.

Improvements in force variability and structure from vision- to memory-guided submaximal isometric knee extension in subacute stroke. J Appl Physiol (1985) 2017; 124:592-603.

Abstract
We examined changes in variability, accuracy, frequency composition, and temporal regularity of force signal from vision-guided to memory-guided force-matching tasks in 17 subacute stroke and 17 age-matched healthy subjects. Subjects performed a unilateral isometric knee extension at 10, 30, and 50% of peak torque [maximum voluntary contraction (MVC)] for 10 s (3 trials each). Visual feedback was removed at the 5-s mark in the first two trials (feedback withdrawal), and 30 s after the second trial the subjects were asked to produce the target force without visual feedback (force recall). The coefficient of variation and constant error were used to quantify force variability and accuracy. Force structure was assessed by the median frequency, relative spectral power in the 0-3-Hz band, and sample entropy of the force signal. At 10% MVC, the force signal in subacute stroke subjects became steadier, more broadband, and temporally more irregular after the withdrawal of visual feedback, with progressively larger error at higher contraction levels. Also, the lack of modulation in the spectral frequency at higher force levels with visual feedback persisted in both the withdrawal and recall conditions. In terms of changes from the visual feedback condition, the feedback withdrawal produced a greater difference between the paretic, nonparetic, and control legs than the force recall. The overall results suggest improvements in force variability and structure from vision- to memory-guided force control in subacute stroke despite decreased accuracy. Different sensory-motor memory retrieval mechanisms seem to be involved in the feedback withdrawal and force recall conditions, which deserves further study. NEW & NOTEWORTHY We demonstrate that in the subacute phase of stroke, force signals during a low-level isometric knee extension become steadier, more broadband in spectral power, and more complex after removal of visual feedback. Larger force errors are produced when recalling target forces than immediately after withdrawing visual feedback. Although visual feedback offers better accuracy, it worsens force variability and structure in subacute stroke. The feedback withdrawal and force recall conditions seem to involve different memory retrieval mechanisms.

Abstract
BACKGROUND Stroke is a major cause of long-term disability in adults. Several systematic reviews have shown that a higher intensity of training can lead to better functional outcomes after stroke. Currently, the resources in inpatient settings are not always sufficient and innovative methods are necessary to meet these recommendations without increasing healthcare costs. A resource efficient method to augment intensity of training could be to involve caregivers in exercise training. A caregiver-mediated exercise programme has the potential to improve outcomes in terms of body function, activities, and participation in people with stroke. In addition, caregivers are more actively involved in the rehabilitation process, which may increase feelings of empowerment with reduced levels of caregiver burden and could facilitate the transition from rehabilitation facility (in hospital, rehabilitation centre, or nursing home) to home setting. As a consequence, length of stay might be reduced and early supported discharge could be enhanced. OBJECTIVES To determine if caregiver-mediated exercises (CME) improve functional ability and health-related quality of life in people with stroke, and to determine the effect on caregiver burden. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (October 2015), CENTRAL (the Cochrane Library, 2015, Issue 10), MEDLINE (1946 to October 2015), Embase (1980 to December 2015), CINAHL (1982 to December 2015), SPORTDiscus (1985 to December 2015), three additional databases (two in October 2015, one in December 2015), and six additional trial registers (October 2015). We also screened reference lists of relevant publications and contacted authors in the field. SELECTION CRITERIA Randomised controlled trials comparing CME to usual care, no intervention, or another intervention as long as it was not caregiver-mediated, aimed at improving motor function in people who have had a stroke. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials. One review author extracted data, and assessed quality and risk of bias, and a second review author cross-checked these data and assessed quality. We determined the quality of the evidence using GRADE. The small number of included studies limited the pre-planned analyses. MAIN RESULTS We included nine trials about CME, of which six trials with 333 patient-caregiver couples were included in the meta-analysis. The small number of studies, participants, and a variety of outcome measures rendered summarising and combining of data in meta-analysis difficult. In addition, in some studies, CME was the only intervention (CME-core), whereas in other studies, caregivers provided another, existing intervention, such as constraint-induced movement therapy. For trials in the latter category, it was difficult to separate the effects of CME from the effects of the other intervention.We found no significant effect of CME on basic ADL when pooling all trial data post intervention (4 studies; standardised mean difference (SMD) 0.21, 95% confidence interval (CI) -0.02 to 0.44; P = 0.07; moderate-quality evidence) or at follow-up (2 studies; mean difference (MD) 2.69, 95% CI -8.18 to 13.55; P = 0.63; low-quality evidence). In addition, we found no significant effects of CME on extended ADL at post intervention (two studies; SMD 0.07, 95% CI -0.21 to 0.35; P = 0.64; low-quality evidence) or at follow-up (2 studies; SMD 0.11, 95% CI -0.17 to 0.39; P = 0.45; low-quality evidence).Caregiver burden did not increase at the end of the intervention (2 studies; SMD -0.04, 95% CI -0.45 to 0.37; P = 0.86; moderate-quality evidence) or at follow-up (1 study; MD 0.60, 95% CI -0.71 to 1.91; P = 0.37; very low-quality evidence).At the end of intervention, CME significantly improved the secondary outcomes of standing balance (3 studies; SMD 0.53, 95% CI 0.19 to 0.87; P = 0.002; low-quality evidence) and quality of life (1 study; physical functioning: MD 12.40, 95% CI 1.67 to 23.13; P = 0.02; mobility: MD 18.20, 95% CI 7.54 to 28.86; P = 0.0008; general recovery: MD 15.10, 95% CI 8.44 to 21.76; P < 0.00001; very low-quality evidence). At follow-up, we found a significant effect in favour of CME for Six-Minute Walking Test distance (1 study; MD 109.50 m, 95% CI 17.12 to 201.88; P = 0.02; very low-quality evidence). We also found a significant effect in favour of the control group at the end of intervention, regarding performance time on the Wolf Motor Function test (2 studies; MD -1.72, 95% CI -2.23 to -1.21; P < 0.00001; low-quality evidence). We found no significant effects for the other secondary outcomes (i.e. PATIENT motor impairment, upper limb function, mood, fatigue, length of stay and adverse events; caregiver: mood and quality of life).In contrast to the primary analysis, sensitivity analysis of CME-core showed a significant effect of CME on basic ADL post intervention (2 studies; MD 9.45, 95% CI 2.11 to 16.78; P = 0.01; moderate-quality evidence).The methodological quality of the included trials and variability in interventions (e.g. content, timing, and duration), affected the validity and generalisability of these observed results. AUTHORS' CONCLUSIONS There is very low- to moderate-quality evidence that CME may be a valuable intervention to augment the pallet of therapeutic options for stroke rehabilitation. Included studies were small, heterogeneous, and some trials had an unclear or high risk of bias. Future high-quality research should determine whether CME interventions are (cost-)effective.

Abstract
INTRODUCTION The Rehabilitation Training (ReTrain) intervention aims to improve functional mobility, adherence to poststroke exercise guidelines and quality of life for people after stroke. A definitive randomised controlled trial (RCT) is required to assess the clinical and cost-effectiveness of ReTrain, which is based on Action for Rehabilitation from Neurological Injury (ARNI). The purpose of this pilot study is to assess the feasibility of such a definitive trial and inform its design. METHODS AND ANALYSIS A 2-group, assessor-blinded, randomised controlled external pilot trial with parallel mixed-methods process evaluation and economic evaluation. 48 participants discharged from clinical rehabilitation despite residual physical disability will be individually randomised 1:1 to ReTrain (25 sessions) or control (exercise advice booklet). Outcome assessment at baseline, 6 and 9 months include Rivermead Mobility Index; Timed Up and Go Test; modified Patient-Specific Functional Scale; 7-day accelerometry; Stroke Self-efficacy Questionnaire, exercise diary, Fatigue Assessment Scale, exercise beliefs and self-efficacy questionnaires, SF-12, EQ-5D-5L, Stroke Quality of Life, Carer Burden Index and Service Receipt Inventory. Feasibility, acceptability and process outcomes include recruitment and retention rates; with measurement burden and trial experiences being explored in qualitative interviews (20 participants, 3 intervention providers). Analyses include descriptive statistics, with 95% CI where appropriate; qualitative themes; intervention fidelity from videos and session checklists; rehearsal of health economic analysis. ETHICS AND DISSEMINATION National Health Service (NHS) National Research Ethics Service approval granted in April 2015; recruitment started in June. Preliminary studies suggested low risk of serious adverse events; however (minor) falls, transitory muscle soreness and high levels of postexercise fatigue are expected. Outputs include pilot data to inform whether to proceed to a definitive RCT and support a funding application; finalised Trainer and Intervention Delivery manuals for multicentre replication of ReTrain; presentations at conferences, public involvement events; internationally recognised peer-reviewed journal publications, open access sources and media releases. TRIAL REGISTRATION NUMBER NCT02429180; Pre-results.

Abstract
OBJECTIVE To evaluate the objective and subjective functional effectiveness of tibial nerve neurotomy (TNN) in post-stroke spastic equinovarus foot (SEF). METHODS In an open study, 23 hemiplegic patients were assessed immediately before TNN and then 5months after TNN. The main outcome measure was the Lower Limb Function Assessment Scale (LL-FAS), which provided an ecologic assessment of impairments in standing and walking (i.e. kinematic abnormalities) and their impacts on activities of daily living. Patients were also assessed for global clinical impression of change, fear of falling, neuromotor impairments, spatiotemporal and video gait parameters and walking capacities. RESULTS TNN had a very marked effect on the level of spasticity and the range of motion in dorsiflexion (p<10(-3)). These changes resulted in better foot positioning when standing and walking (particularly in stance), which was perceived very favorably by the patients. There was a clear, patient-perceived improvement in activities performed when standing and walking (LL-FAS (p<0.01)), the global clinical impression of change (p<10(-3)) and the fear of falling (p=0.022) that was not revealed by conventional, objective measurements (New Functional Ambulation Classification, Rivermead Mobility Index). CONCLUSION TNN is an effective treatment for post-stroke SEF; it is associated with a patient-reported improvement in standing and walking abilities during activities of daily living. Further research must now assess the long-term subjective efficacy of TNN.

Abstract
The aim of this study was to evaluate the effects of Kinesio Tape (KT) application to quadriceps muscles on isokinetic muscle strength, gait, and functional parameters in patients with stroke. Twenty-four patients were allocated into KT and control groups. All patients participated in the same conventional rehabilitation program 5 times/wk for 4 wk. In addition, KT was applied to quadriceps muscles bilaterally to the patients in the KT group. Compared with baseline, peak torque levels increased significantly in both groups (all p < 0.05). However, change levels were significantly higher in the KT group than the control group at 60 degrees/second angular velocity (AV) in extension (p = 0.04) and 60 and 180 degrees/second AV in flexion (both p = 0.02) on the paretic side. Moreover, the change levels were more prominent in the KT group at 60 and 180 degrees/second AV in extension (p = 0.03 and p = 0.04, respectively) on the nonparetic side. Gait, balance, mobility, and quality of life values improved significantly in both groups (all p < 0.05), yet the change levels between the groups did not reach significance (p > 0.05). KT application to quadriceps muscles in addition to conventional exercises for 4 wk is effective on isokinetic but not functional parameters.

Abstract
Background Even though Swedish national guidelines for stroke care (SNGSC) have been accessible for nearly a decade access to stroke rehabilitation in out-patient health care vary considerably. In order to aid future interventions studies for implementation of SNGSC, this study assessed the feasibility and acceptability of study procedures including analysis of the context in out-patient health care settings. Methods The feasibility and acceptability of recruitment, observations and interviews with managers, staff and patients were assessed, as well as the feasibility of surveying health care records. Results To identify patients from the the hospitals was feasible but not from out-patient care where a need to relieve clinical staff of the recruitment process was identified. Assessing adherence to guidelines and standardized evaluations of patient outcomes through health care records was found to be feasible and suitable assessment tools to evaluate patient outcome were identified. Interviews were found to be a feasible and acceptable tool to survey the context of the health care setting. Conclusion In this feasibility study a variety of qualitative and quantitative data collection procedures and measures were tested. The results indicate what can be used as a set of feasible and acceptable data collection procedures and suitable measures for studying implementation of stroke guidelines in an out-patient health care context.

Caregiver-mediated exercises with e-health support for early supported discharge after stroke (CARE4STROKE): study protocol for a randomized controlled trial. BMC Neurol 2015; 15:193. [PMID: 26452543 PMCID: PMC4600217 DOI: 10.1186/s12883-015-0440-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2015] [Accepted: 09/25/2015] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Several systematic reviews have shown that additional exercise therapy has a positive effect on functional outcome after stroke. However, there is an urgent need for resource-efficient methods to augment rehabilitation services without increasing health care costs. Asking informal caregivers to do exercises with their loved ones, combined with e-health services may be a cost-effective method to promote early supported discharge with increased functional outcome. The primary aim of the CARE4STROKE study is to evaluate the effects and cost-effectiveness of a caregiver-mediated exercises program combined with e-health services after stroke in terms of self-reported mobility and length of stay. METHODS An observer-blinded randomized controlled trial, in which 66 stroke-patients admitted to a hospital stroke unit, rehabilitation center or nursing home are randomly assigned to either 8 weeks of the CARE4STROKE program in addition to usual care (i.e., experimental group) or 8 weeks of usual care alone (i.e., control group). The CARE4STROKE program is compiled in consultation with a trained physical therapist. A tablet computer is used to present video-based exercises for gait and gait-related activities in which a caregiver acts as an exercise coach. Primary outcomes are the mobility domain of the Stroke Impact Scale and length of stay. Secondary outcomes are the other domains of the Stroke Impact Scale, motor impairment, strength, walking ability, balance, mobility, (Extended) Activities of Daily Living, psychosocial functioning, self-efficacy, fatigue, health-related quality of life of the patient as well as the experienced strain, psychosocial functioning and quality of life of the caregiver. An economic evaluation will be conducted from the societal and health care perspective. DISCUSSION The main aspects of the CARE4STROKE program are 1) increasing intensity of training by doing exercises with a caregiver in addition to usual care and 2) e-health support. We hypothesize this program leads to better functional outcome and early supported discharge, resulting in reduced costs. TRIAL REGISTRATION The study is registered in the Dutch trial register as NTR4300, registered 2 December 2013.

Variability, frequency composition, and complexity of submaximal isometric knee extension force from subacute to chronic stroke. Neuroscience 2014; 273:189-98. [PMID: 24840274 DOI: 10.1016/j.neuroscience.2014.05.018] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2014] [Revised: 05/09/2014] [Accepted: 05/10/2014] [Indexed: 11/27/2022]
Abstract
We examined changes in the variability, frequency composition, and complexity of force signal from subacute to chronic stage of stroke during maintenance of isometric knee extension and compared these parameters between chronic stroke and healthy subjects. The sample included 15 healthy (65±8 years) and 23 chronic stroke subjects (65±14 years, 6-112 months post-stroke) of whom 10 (64±15 years) were also examined 11-22 days post-stroke (subacute stage). The subjects performed isometric knee extension at 10%, 20%, 30%, and 50% of peak torque for 10s (two trials each). Coefficient of variation (CV) was used as a measure of force variability. The median frequency and relative power in the 0-3, 4-6, and 8-12 Hz bands were obtained through a power spectrum analysis of the force signal. The signal complexity was quantified using the sample entropy (SampEn). The longitudinal analysis revealed a significant decrease in CV from subacute to chronic stage across all contraction levels (P<0.001) but no significant changes in the frequency and entropy parameters. Comparison between the chronic stroke and control subjects revealed no significant difference in CV across the force levels (P>0.05) but significantly decreased median frequency (P<0.01), with the relative power increased in 0-3 Hz band and decreased in 4-6 and 8-12 Hz bands in both paretic and non-paretic legs (P<0.001). SampEn was also significantly decreased in chronic stroke, bilaterally (P<0.001). These results indicate a shift toward lower frequencies and a less complex physiological process underlying force control in chronic stroke. The overall results suggest the improvement in force variability from subacute to chronic stroke but without normalization in the frequency composition and complexity of the force signal. Thus, disordered structure of the force signal remains a marker of impaired motor control long after stroke occurrence despite apparent recovery in force variability.

Abstract
Background Responsiveness refers to a measurement tool’s ability to detect change in performance over time. The aim of the review was to summarise studies of responsiveness of lower limb physical performance measures during inpatient care after stroke. Methods A systematic literature review was conducted. Prospective studies that included participants with a diagnosis of stroke, were commenced in the acute or subacute phase of inpatient care and included a measure of a lower limb physical performance were included in this review. Results Twenty-one studies met these inclusion criteria. A variety of measures were investigated including the Berg Balance Scale, various timed walking tests and the Rivermead Mobility Index. Ten of the included studies had small sample sizes (50 participants or less), 2 studies used a convenience sample rather than consecutive recruitment and 5 studies excluded potential participants with poor physical abilities at baseline. Responsiveness varied between and within studies but was generally large, Effect Size (ES) or Standardised Response Mean (SRM) > 0.8. Measures displaying large responsiveness included the twelve-minute walk test (SRM 1.90) and the Modified Rivermead Mobility Index (SRM 1.31) when re-measured at four weeks after stroke, and the Berg Balance Scale (ES 1.11) and Postural Assessment Scale for Stroke Patients (ES 1.12) when re-measured at approximately six months after stroke. Conclusion Studies conducted to date have generally found physical performance measures after stroke to have large responsiveness i.e., to be able to detect changes. Further investigation of the responsiveness of measurement tools after stroke in larger prospective cohort studies is required.

Abstract
Purpose To systematically review the psychometric properties of outcome measures used in stroke self-management interventions (SMIs) to (1) inform researchers, clinicians and commissioners about the properties of the measures in use and (2) make recommendations for the future development of self-management measurement in stroke. Methods Electronic databases, government websites, generic internet search engines and hand searches of reference lists. Abstracts were selected against inclusion criteria and retrieved for appraisal and systematically scored, using the COSMIN checklist. Results Thirteen studies of stroke self-management originating from six countries were identified. Forty-three different measures (mean 5.08/study, SD 2.19) were adopted to evaluate self-SMIs. No studies measured self-management as a discreet concept. Six (46%) studies included untested measures. Eleven (85%) studies included at least one measure without reported reliability and validity in stroke populations. Conclusions The use of outcome measures which are related, indirect or proxy indicators of self-management and that have questionable reliability and validity, contributes to an inability to sensitively evaluate the effectiveness of stroke self-SMIs. Further enquiry into how the concept of self-management in stroke operates, would help to clarify the nature and range of specific self-management activities to be targeted and aid the selection of existing appropriate measures or the development of new measures.

Abstract
Critical illness can lead to muscle wasting, functional decline and long-term disability. This is well described subjectively in the literature; however, to date, objective measures have proved elusive. This narrative review aims to explore the objective measurement tools available to assess intensive care unit-acquired weakness, to review the psychometric properties of these tools and to show current practice and the obstacles we face in the development of new measurement scales.

Abstract
BACKGROUND Recovery after acute stroke is expected to continue for a long time but is most rapid during the first few days after onset. Because the cost of hospital care is rising constantly, there is increasing pressure from various administrative bodies to reduce the duration of hospital stay. To select the optimal level of care for elderly patients with stroke-related disability, it is important to be aware of adequate discharge destinations and to have reliable predictors for the length of institutional stay (LOS) (ie in hospital or nursing home). PURPOSE The purpose of the study was to find feasible prognostic indicators for the LOS, to be used 5 days after acute stroke, in persons 65 years and older. METHODS One hundred fifteen consecutive persons, 65 years and older, were assessed 5 days poststroke for the following: consciousness (Glasgow Coma Scale), language (aphasia/no aphasia), perceptual (Cancellation Tasks and Block Test), emotional (lability/no lability), energy and drive (Montgomery-Åsberg Depression Scale), mental (Mini-Mental State Examination), somatosensory (normal/impaired), and urinary (continent/incontinent) functions; mobility (Rivermead mobility index [RMI]); activities of daily living (Barthel Index); and side of hemiplegia or hemiparesis. In addition, previous living arrangements (alone vs with another person), stroke characteristics, and demographic information were documented. Length of institutional stay was recorded 5 days to 3 months poststroke onset. RESULTS Multiple regression survival analyses showed that the factors with the greatest positive impact on short LOS, 5 days poststroke, were the following: no previous stroke; Glasgow Coma Scale ≥ 13 (mild brain injury); and RMI ≥ 4 points, corresponding to the ability to rise from a chair in less than 15 seconds and stand there for 15 seconds with or without an aid. CONCLUSIONS In addition to medical appraisal, the RMI ≥ 4 points, a quickly performed test, can be used to predict short LOS for persons with stroke as early as 5 days after stroke onset.

Abstract
BACKGROUND AND PURPOSE A general hypothesis is that pain following stroke (PFS) causes disabilities. However, the clinical implication of PFS on other disabilities after stroke and vice versa has not been fully investigated. The aims of this observational study were to analyze the correlation between PFS and other disabilities at different time points after stroke, whether PFS can be a predictor of coming disabilities and whether other disabilities can be predictors of coming PFS. METHODS Patients with a first-ever stroke were assessed initially (n = 109), and at 3 (n = 95) and 18 months (n = 66) after stroke for PFS, mobility, self-care as well as touch, proprioceptive, muscle tone, and movement functions. RESULTS PFS was correlated to impaired upper extremity movement function on all occasions, while the correlations between PFS and other disabilities varied across the three occasions. Initial PFS and PFS at 3 months did not independently predict coming disabilities. Initial mobility limitation independently predicted PFS at 3 months and impaired touch function, initially and at 3 months, independently predicted PFS at 18 months. No other disabilities independently predicted coming PFS. CONCLUSIONS The present results do not support the hypothesis that PFS causes other disabilities. Our results indicate that PFS is correlated to other disabilities; however, no ultimate conclusions can be drawn on causality. PFS was not a predictor of coming disabilities, while some disabilities were predictors of coming PFS.

Abstract
We tested the hypothesis that force variability and error during maintenance of submaximal isometric knee extension are greater in subacute stroke patients than in controls and are related to motor impairments. Contralesional (more-affected) and ipsilesional (less-affected) legs of 33 stroke patients with sufficiently high motor abilities (62 ± 13 yr, 16 ± 2 days postinjury) and the dominant leg of 20 controls (62 ± 10 yr) were tested in sitting position. After peak knee extension torque [maximum voluntary contraction (MVC)] was established, subjects maintained 10, 20, 30, and 50% of MVC as steady and accurate as possible for 10 s by matching voluntary force to the target level displayed on a monitor. Coefficient of variation (CV) and root-mean-square error (RMSE) were used to quantify force variability and error, respectively. The MVC was significantly smaller in the more-affected than less-affected leg, and both were significantly lower than in controls. The CV was significantly larger in the more-affected than less-affected leg at 20 and 50% MVC, whereas both were significantly larger compared with controls across all force levels. Both more-affected and less-affected legs of patients showed significantly greater RMSE than controls at 30 and 50% MVC. The CV and RMSE were not related to the Fugl-Meyer motor score or to the Rivermead Mobility Index. The CV negatively correlated with MVC in controls but only in the less-affected leg of patients. It is concluded that isometric knee extension strength and force control are bilaterally impaired soon after stroke but more so in the more-affected leg. Future studies should examine possible mechanisms and the evolution of these changes.

Abstract
Background. Several studies have examined determinants related to post-stroke fatigue. However, it is unclear which determinants can predict an increase in poststroke fatigue over time. Aim. This prospective cohort study aimed to identify determinants which predict an increase in post-stroke fatigue. Methods. A total of 250 patients with stroke were examined at inpatient rehabilitation discharge (T0) and 24 weeks later (T1). Fatigue was measured using the Fatigue Severity Scale (FSS). An increase in post-stroke fatigue was defined as an increase in the FSS score beyond the 95% limits of the standard error of measurement of the FSS (i.e., 1.41 points) between T0 and T1. Candidate determinants included personal factors, stroke characteristics, physical, cognitive, and emotional functions, and activities and participation and were assessed at T0. Factors predicting an increase in fatigue were identified using forward multivariate logistic regression analysis. Results. The only independent predictor of an increase in post-stroke fatigue was FSS (OR 0.50; 0.38–0.64, P < 0.001). The model including FSS at baseline correctly predicted 7.9% of the patients who showed increased fatigue at T1. Conclusion. The prognostic model to predict an increase in fatigue after stroke has limited predictive value, but baseline fatigue is the most important independent predictor. Overall, fatigue levels remained stable over time.

Abstract
PURPOSE To assess the inter-rater reliability, internal consistency and convergent validity of the Modified Rivermead Mobility Index (MRMI) in a mixed neurological population. METHOD The MRMI was scored for 30 consecutive patients (mean age 54.5+/-15.6 years) by two individual testers. Reliability was examined using intraclass correlation coefficients (ICC3,1) and Bland and Altman plots; internal consistency reliability using Cronbach's alpha (alpha) and convergent validity using Spearman's correlation coefficient (rho) test to compare the MRMI to the 10-m walk test as a gold standard of mobility. As the majority of patients had bilateral deficits, the MRMI was measured and added independently for both sides. RESULTS The inter-rater reliability was excellent: ICC (95% CI)=0.93(0.86, 0.96). The Bland and Altman plots contained most data points and there was perfect agreement between raters bilaterally in 27% of cases, with a difference of one point in 60% of cases on the left and 63% of cases on the right. Internal consistency was good at alpha=0.72 (Rater 1) and 0.80 (Rater 2). The Spearman rho between MRMI and the 10-m walk test was high at 0.86. CONCLUSIONS The MRMI was shown to have high levels of reliability in a mixed neurological population but we recommend that its psychometric properties are further investigated to establish the true clinical utility of this measure.

Abstract
OBJECTIVE To investigate validity and reliability of the Functional Gait Assessment (FGA) (German version) as a measure for balance abilities during walking in subacute stroke patients. DESIGN Cohort study. SETTING Inpatient rehabilitation center. PARTICIPANTS Ambulatory subjects (N=28) at a maximum of 6 months after stroke participated in this study. One direct observer and 2 video observers rated the FGA. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Performance of the FGA was video recorded and directly rated. For testing concurrent validity of the FGA, subjects also completed testing in the Berg Balance Scale, fast walking speed, the Functional Ambulatory Category, the Rivermead Mobility Index, and the Barthel Index. Intrarater reliability, interrater reliability, and concurrent validity of the FGA were analyzed. RESULTS Intrarater (intraclass correlation coefficient=.97) and interrater reliability (intraclass correlation coefficient=.94) were almost perfect for total scores. Reliability of single items varied between substantial and almost perfect values. Analysis revealed significant correlations between the FGA and other measures of gait and balance functions between Spearman rho values of .71 and .93. The FGA differs significantly between levels of gait ability (Functional Ambulatory Category) (P< or =.01). CONCLUSIONS Almost perfect intrarater and interrater reliability for total FGA scores and good concurrent validity were shown in this study. Therefore, the FGA (German version) can be used as a reliable and valid tool to assess functional gait performance of patients in subacute stages after stroke.

Abstract
Objective: To identify psychometrically robust and clinically feasible measures of walking and mobility in people with neurological conditions Data sources: MEDLINE, CINAHL, EMBASE, PEDro and AMED. Review methods: Independent reviewers selected and extracted data from articles that assessed the reliability, validity, sensitivity to change or clinical utility of measures of walking and mobility in adult neurological conditions. Measures with ‘good’ psychometrics and 9/10 clinical utility scores were recommended. Results: Seventeen measures were selected. Of these, the 5-m and 10-m walk tests, six-minute walk test, High Level Mobility Assessment Tool (HiMAT) and the Rivermead Mobility Index (RMI) reached the required standards and are usable in clinical practice. None of the recommended measures assessed wheelchair mobility. The least frequently assessed property was sensitivity to change. Further measures could be recommended if the minimal detectable change were demonstrated. Conclusion: The 5-m, 10-m and six-minute walk test, High Level Mobility Assessment Tool and the Rivermead Mobility Index are psychometrically robust measures of walking and mobility and are feasible for use in clinical practice.

Abstract
Background Most patients who suffer a stroke experience reduced walking competency and health-related quality of life (HRQoL). A key factor in effective stroke rehabilitation is intensive, task-specific training. Recent studies suggest that intensive, patient-tailored training can be organized as a circuit with a series of task-oriented workstations. Primary aim of the FIT-Stroke trial is to evaluate the effects and cost-effectiveness of a structured, progressive task-oriented circuit class training (CCT) programme, compared to usual physiotherapeutic care during outpatient rehabilitation in a rehabilitation centre. The task-oriented CCT will be applied in groups of 4 to 6 patients. Outcome will be defined in terms of gait and gait-related ADLs after stroke. The trial will also investigate the generalizability of treatment effects of task-oriented CCT in terms of perceived fatigue, anxiety, depression and perceived HRQoL. Methods/design The multicentre single-blinded randomized trial will include 220 stroke patients discharged to the community from inpatient rehabilitation, who are able to communicate and walk at least 10 m without physical, hands-on assistance. After discharge from inpatient rehabilitation, patients in the experimental group will receive task-oriented CCT two times a week for 12 weeks at the physiotherapy department of the rehabilitation centre. Control group patients will receive usual individual, face-to-face, physiotherapy. Costs will be evaluated by having each patient keep a cost diary for the first 24 weeks after randomisation. Primary outcomes are the mobility part of the Stroke Impact Scale (SIS-3.0) and the EuroQol. Secondary outcomes are the other domains of SIS-3.0, lower limb muscle strength, walking endurance, gait speed, balance, confidence not to fall, instrumental ADL, fatigue, anxiety, depression and HRQoL. Discussion Based on assumptions about the effect of intensity of practice and specificity of treatment effects, FIT-Stroke will address two key aims. The first aim is to investigate the effects of task-oriented CCT on walking competency and HRQoL compared to usual face-to-face physiotherapy. The second aim is to reveal the cost-effectiveness of task-oriented CCT in the first 6 months post stroke. Both aims were recently recommended as priorities by the American Hearth Association and Stroke Council. Trial registration This study is registered in the Dutch Trial Register as NTR1534.

Abstract
BACKGROUND Overground gait training forms a major part of physical therapy services for chronic stroke patients in almost every setting. Overground gait training refers to physical therapists' observation and cueing of the patient's walking pattern along with related exercises, but does not include high-technology aids such as functional electrical stimulation or body weight support. OBJECTIVES To assess the effects of overground physical therapy gait training on walking ability for chronic stroke patients with mobility deficits. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched March 2008), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2008), MEDLINE (1966 to May 2008), EMBASE (1980 to May 2008), CINAHL (1982 to May 2008), AMED (1985 to March 2008), Science Citation Index Expanded (1981 to May 2008), ISI Proceedings (Web of Science, 1982 to May 2006), Physiotherapy Evidence Database (http://www.pedro.org.au/) (May 2008), REHABDATA (http://www.naric.com/research/rehab/) (1956 to May 2008), http://www.clinicaltrials.gov (May 2008), http://www.controlled-trials.com/ (May 2008), and http://www.strokecenter.org/ (May 2008). We also searched reference lists of relevant articles, and contacted authors and trial investigators. SELECTION CRITERIA Randomised controlled trials comparing overground physical therapy gait training with a placebo intervention or no treatment for chronic stroke patients with mobility deficits. DATA COLLECTION AND ANALYSIS Pairs of authors independently selected trials. Three authors independently extracted data and assessed quality. We contacted study authors for additional information. MAIN RESULTS We included nine studies involving 499 participants. We found no evidence for a benefit on the primary variable, post-test gait function, based on three studies with 269 participants. Uni-dimensional performance variables did show significant effects post-test. Gait speed increased by 0.07 metres per second (95% confidence interval (CI) 0.05 to 0.10) based on seven studies with 396 participants, timed up-and-go (TUG) test improved by 1.81 seconds (95% CI -2.29 to -1.33), and six-minute-walk test (6MWT) increased by 26.06 metres (95% CI 7.14 to 44.97) based on four studies with 181 participants. We found no significant differences in deaths/disabilities or in adverse effects, based on published reports or personal communication from all of the included studies. AUTHORS' CONCLUSIONS We found insufficient evidence to determine if overground physical therapy gait training benefits gait function in patients with chronic stroke, though limited evidence suggests small benefits for uni-dimensional variables such as gait speed or 6MWT. These findings must be replicated by large, high quality studies using varied outcome measures.
