<i>Background:</i> Participating in regular physical activity is an important part of healthy aging. There increased risk for inactivity associated with aging and the becomes greater adults who have a chronic disease. However, there limited information on current levels older even less those diseases. <i>Objective:</i> Our primary objective was to determine proportion achieved recommended amount weekly (≥1,000 kcal/week). The secondary objectives were identify...
To examine the reliability and validity of Activities-specific Balance Confidence (ABC) scale among individuals with stroke.Descriptive measurement study using a 4-week test-retest design. Data were collected at tertiary rehabilitation centre form community-dwelling sample ambulatory older adults who sustained one stroke least 1 year prior to study. During first session, total (n = 77) completed ABC as well Berg Scale (BBS) gait speed. The 24), subset larger data set, again 4 weeks...
The purpose of this study was to identify factors that predict an individual's subjective quality life (QoL) after having a lower limb amputation.Cross-sectional descriptive design.A total 415 unilateral, above knee (27.0%) and below (73.0%) amputees with average age 61.9 years (SD = 15.7) who had lost their related vascular (53.0%) or non-vascular (47.0%) etiology.Medical chart review, questionnaires (Frenchay Activities Index, Interpersonal Support Evaluation List, the Center for...
Background and Purpose— More than 70% of individuals who have a stroke experience upper limb deficits that impact daily activities. Increased amount therapy has positive effects; however, practical inexpensive methods are needed to deliver this increase in therapy. Methods— This was multi-site single blind randomized controlled trial determine the effectiveness 4-week self-administered graded repetitive supplementary program (GRASP) on arm recovery stroke. 103 inpatients with were...
Background The literature suggests that stroke is a major risk factor for falls, but there lack of prospective, controlled studies which quantify fall-risk after stroke. purpose this study was to compare the rates, location and predictors among individuals recently discharged home from rehabilitation age sex matched controls. Methodology/Principal Findings A sample 80 people with 90 controls received baseline assessments balance, mobility balance confidence. Falls were recorded prospectively...
A simple computationally efficient closed-form model has been developed to determine the pull-in voltage of a cantilever beam actuated by electrostatic force. The approach is based on linearized uniform approximate nonlinear pressure and load deflection under pressure. includes due fringing field capacitances derived from Meijs Fokkema's highly accurate empirical expression for capacitance VLSI on-chip interconnect. verified comparing results with published experimentally 3D finite element...
Abstract Background and Purpose. Walk tests provide essential outcome information when assessing ambulation of individuals with lower-limb amputation a prosthetic device. Existing have limitations such as ceiling effects or insufficient challenge. The objective this study was to assess the reliability validity data for clinical measure basic mobility, L Test Functional Mobility (L Test). Subjects. For methodological study, 93 people unilateral amputations (74% transtibial, 26% transfemoral;...
The Spinal Cord Injury Rehabilitation Evidence (SCIRE) is a synthesis of the research evidence underlying rehabilitation interventions to improve health people living with SCI. SCIRE covers comprehensive set topics and in this issue we present six papers relevant SCI clinicians (SCI inpatient practices, gait strategies, upper extremity reconstructive surgery, spasticity treatments, cardiovascular bone health). used systematic well-defined protocol assess synthesize evidence. Each article was...
Background and Purpose Many people with stroke have a low level of satisfaction community reintegration. Although previous studies focused on the effect physical factors reintegration, psychological factors, such as balance self-efficacy, has been ignored. The purpose this study was to determine contribution self-efficacy reintegration in older adults chronic stroke. Subjects A sample 63 community-dwelling (50 years age or older) (onset 1 year more) participated study. Methods This involved...
Nonexperimental methodological study.To determine the interrater and intrarater reliability validity of using observational risk-screening guidelines to evaluate dynamic knee valgus.A deficiency in neuromuscular control hip has been identified as a key risk factor for noncontact anterior cruciate ligament (ACL) injury postpubescent females. This can manifest itself valgus alignment during tasks involving flexion. There are currently no scientifically tested methods screen clinic or on...
Purpose: To describe current practices for manual wheelchair (MWC) skills training in Canadian rehabilitation centers. Methods: An online survey was sent to practice leaders occupational (OT) and physical therapy (PT) at 87 Responses were solicited from individuals who could report about facilities with least 10 beds designated rehabilitation. Thirty-four questions asked about: (1) demographics, (2) components of MWC training, (3) amount (4) use validated programs (5) perceived barriers...
Mobility impairments are the third leading cause of disability for community-dwelling Canadians. Wheelchairs and scooters help compensate these challenges. There limited data within last decade estimating prevalence wheelchair scooter use in Canada.The aims this study were: (1) to estimate Canada (2) explore relevant demographic characteristics users.This was a secondary analysis cross-sectional national survey.The Canadian Survey on Disability (2012) collected from individuals aged 15 years...
Abstract Background and Purpose. Confidence in a person's balance has been shown to be an important predictor of social activity among people with lower-limb amputations. The purposes this study were describe confidence transtibial or transfemoral amputations compare whose due vascular nonvascular causes. Subjects Methods. A survey sample 435 community-dwelling individuals from 2 regional clinics was conducted. consisted unilateral (26.7%) (73.3%) who lost their limb for (53%) (47%) reasons....
Chronic conditions could negatively affect the quality of life older adults. This may be partially due to a relative lack physical activity. We examined whether activity mediates relationship between different chronic and several health outcomes that are important The data were taken from Canadian Community Health Survey (cycle 1.1), cross-section survey completed in 2001. Only respondents who 65 years or included our study (N = 22,432). Utilities Index Mark 3 (HUI3) was used measure overall...
