PURPOSE Differences in gross mechanical efficiency between experienced and inexperienced wheelchair users may be brought about by differences in propulsion technique. The purpose of this experiment was to study changes in propulsion technique (defined by force application, left-right symmetry, intercycle variability, and timing) and gross mechanical(More)
OBJECTIVE Investigation of the effect of visual feedback on effective hand rim wheelchair force production and the subsequent effect on gross mechanical efficiency. DESIGN Ten subjects in an experimental group and 10 subjects in a control group practised three weeks (3.wk(-1), i.e., a pre-test and 8 trials) on a computer-controlled wheelchair ergometer.(More)
BACKGROUND To evaluate the effect of a 7-week low-intensity hand rim wheelchair training on the submaximal metabolic cost, mechanical efficiency and propulsion technique in able-bodied participants. METHODS Participants were randomly divided over an experimental group (n=14) and a control group (n=7). The experimental group received 7 weeks wheelchair(More)
OBJECTIVE To evaluate the effect of body weight-supported gait training on restoration of walking, activities of daily living, and quality of life in persons with an incomplete spinal cord injury by a systematic review of the literature. METHODS Cochrane, MEDLINE, EMBASE, CINAHL, PEDro, DocOnline were searched and identified studies were assessed for(More)
This article is considered relevant because: 1) car driving is an everyday and safety-critical task; 2) simulators are used to an increasing extent for driver training (related topics: training, virtual reality, human-machine interaction); 3) the article addresses relationships between performance in the simulator and driving test results--a relevant topic(More)
OBJECTIVE To assess changes in physical capacity and its determinants in persons with a spinal cord injury. DESIGN Prospective cohort study. Measurements at the start of active rehabilitation (t1), 3 months later (t2), at discharge (t3), and 1 year after discharge (t4). SETTING Eight rehabilitation centers in The Netherlands. PARTICIPANTS A total of(More)
By studying exercise and performance in hand-cycling in both activities of daily living and in Paralympic sport settings, new insights can be gained for rehabilitation practice, adapted physical activity, and sports. This review looks into the pros and cons of hand-cycling in both rehabilitation and optimal sports performance settings as suggested from the(More)
Those with lower limb disabilities are often dependent on manually propelled wheelchairs for their mobility, in Europe today some 3.3 million people. This implies a transfer from leg to arm work for ambulation and all other activities of daily living (ADL). Compared to the legs, arm work is less efficient and more straining, and leads to a lower physical(More)
OBJECTIVE To investigate the effect of different wheelchair stroke patterns on efficiency and propulsion technique (force application and timing). DESIGN Inexperienced, able-bodied subjects were randomly divided into two velocity groups (1.11 m/sec [n = 13] and 1.39 m/sec [n = 11]). An external (medium) load was set at 0.23 N/kg. Subjects performed four(More)
OBJECTIVE To identify different life satisfaction trajectories in the period between the start of active spinal cord injury (SCI) rehabilitation and 5 years after discharge, and to find predictors for distinguishing between trajectories. The hypotheses were that different life satisfaction trajectories would be identified and that demographic, lesion,(More)
