Hemiparesis resulting in functional limitation of an upper extremity is common among stroke survivors. Although existing evidence suggests that increasing intensity rehabilitation therapy results better motor recovery, limited available on the efficacy virtual reality for rehabilitation.In this pilot, randomized, single-blinded clinical trial with 2 parallel groups involving patients within months, we compared feasibility, safety, and using Nintendo Wii gaming system (VRWii) versus...
Gait performance is affected by neurodegeneration in aging and has the potential to be used as a clinical marker for progression from mild cognitive impairment (MCI) dementia. A dual-task gait test evaluating cognitive-motor interface may predict dementia older adults with MCI.To determine whether associated incident MCI.The Brain Study an ongoing prospective cohort study of community-dwelling that enrolled 112 MCI. Participants were followed up 6 years, biannual visits including neurologic,...
Background. Recent studies highlight the importance of compensatory stepping to preserve stability, and spatial temporal demands placed on control this reaction. Age-related changes in could greatly influence risk falling. The present study compares, healthy elderly young adults, characteristics responses unpredictable postural perturbations.
Background. Lateral falls are common in older adults and associated with an elevated risk of hip fracture, compared other directions. Although rapid stepping movements can play important functional role maintaining balance, control lateral is a complex demanding motor task. This study examined whether there age-related differences the behavior used to recover from loss balance. Methods. Rapid reactions were evoked healthy, active young (aged 20–30 years; \(\mathrm{N}\ =\ 10\) ) 65–73...
Objective. The aim of this study was to establish the efficacy a therapeutic intervention based on functional electrical stimulation (FES) therapy improve reaching and grasping function after severe hemiplegia due stroke. Methods. A total 21 subjects with acute stroke were randomized into 2 groups, FES plus conventional occupational physiotherapy (FES group) or only (control 5 days week for 12 16 weeks. third group 7 chronic (at least months poststroke) received (chronic pre—post training...
Background. One of the more pervasive effects aging is loss cutaneous sensation, which appears to correlate with impaired postural control and increased risk falling. This study examined potential for compensating destabilizing reduced sensitivity by placing a raised edge underneath perimeter plantar foot surface, so as facilitate sensation from stability boundaries base support. Methods. The main experiment involved 14 healthy older adults (aged 65–73) selected because they were known,...
Healthy young adults (n = 39) were asked to perform four different secondary cognitive tasks during quiet unperturbed stance, in order investigate the influence of physiological arousal and attention distraction on control spontaneous postural sway. During each task, activity was quantified terms center-of-pressure displacement, leg-muscle activation, ankle hip rotation. Arousal monitored via skin conductance, questionnaires used assess state anxiety. Respiratory trunk movements also...
There is little information about the quality of gait in years following stroke. Long-term changes mobility, using global indices function, suggest a decline well after initial rehabilitation. However, mobility do not reveal more specific walking competency or underlying gait-specific impairment.The authors used cross-sectional design with measures (velocity and symmetry) to investigate whether deterioration occurs over long term poststroke.Data were abstracted from standardized database...
Background. Although the consequences of spinal cord injury (SCI) within and peripheral nervous system have been studied extensively, influence SCI on supraspinal structures during recovery remains largely unexplored. Objective. To assess temporal changes in cortical sensorimotor representations beginning subacute phase following determine if an association exists between plastic areas movement postinjury. Methods. Functional magnetic resonance imaging (fMRI) was used to study 6 patients for...
and objective. In spite of the challenges, engaging in exercise programs very early after stroke may positively influence aerobic capacity stroke-related outcomes, including walking ability. The objective this study was to evaluate feasibility adding cycle ergometer training conventional rehabilitation determine effects on capacity, ability, health-related quality life.A prospective matched control design used. All participants performed a graded maximal test semi-recumbent ergometer,...
Maintaining and controlling postural balance is important for activities of daily living, with poor being predictive future falls. This study investigated eyes open closed standing posturography elderly adults to identify differences determine appropriate outcome measure cut-off scores prospective faller, single-faller, multi-faller, non-faller classifications. 100 older (75.5 ± 6.7 years) stood quietly then while Wii Balance Board data were collected. Range in anterior-posterior (AP)...
Background. Cognitive benefits obtained from exercise in healthy populations support the idea that aerobic and resistance training (AT+RT) would confer benefit for poststroke recovery. However, there is little evidence regarding effectiveness of such programs. Objective. To evaluate effects a 6-month program AT+RT on cognition consecutively enrolled patients with motor impairments ≥10 weeks poststroke. Methods. Outcomes were measured before after 6 months 41 patients. Cognition was by...
A new paradigm is emerging in which mobility and cognitive impairments, previously studied, diagnosed, managed separately older adults, are fact regulated by shared brain resources. Deterioration these mechanisms normal aging neurodegeneration increases the risk of developing dementia, falls, fractures. This requires an integrated approach to measuring both domains. We aim identify a complementary battery existing tests cognition community-dwelling adults that enable assessment...
Little information exists about longitudinal changes in spatiotemporal gait asymmetry during rehabilitation, despite it being a common goal. Objectives. To describe over rehabilitation and examine relationships with other poststroke impairments.Retrospective chart reviews were conducted for 71 stroke inpatients. Admission discharge measures of symmetry, velocity, motor impairment, mobility balance extracted change scores calculated. Relationships between symmetry investigated Spearman...
