Filter frequency selection for manual wheelchair biomechanics.
Wheelchair locomotion is an important form of mobility for many individuals with spinal cord injury. However, manual wheelchair propulsion can lead to upper-limb pain and can be very inefficient. This has led investigators to apply biomechanics to the study of wheelchair use. The objectives of this study were (1) to determine the frequency content of the motion of both hands during two speeds o...
متن کاملBiomechanics of Pediatric Manual Wheelchair Mobility
Currently, there is limited research of the biomechanics of pediatric manual wheelchair mobility. Specifically, the biomechanics of functional tasks and their relationship to joint pain and health is not well understood. To contribute to this knowledge gap, a quantitative rehabilitation approach was applied for characterizing upper extremity biomechanics of manual wheelchair mobility in childre...
متن کاملThe effect of seat position on wheelchair propulsion biomechanics.
This study examined the effect of seat position on handrim biomechanics. Thirteen experienced users propelled a wheelchair over a smooth level floor at a self-selected speed. Kinetic and temporal-distance data were collected with the use of an instrumented rim and a motion analysis system. A custom-designed axle was used to change the seat position. We used repeated measures analysis of varianc...
متن کاملA fundamental model of quasi-static wheelchair biomechanics.
The performance of a wheelchair system is a function of user anatomy, including arm segment lengths and muscle parameters, and wheelchair geometry, in particular, seat position relative to the wheel hub. To quantify performance, researchers have proposed a number of predictive models. In particular, the model proposed by Richter is extremely useful for providing initial analysis as it is simple...
متن کاملInfluence of trunk flexion on biomechanics of wheelchair propulsion.
. Propulsion styles that are characterized by high stresses may influence the susceptibility of manual wheelchair users (MWCU) to upper limb injury. An experimental, crosssectional study was designed to compare physiological and biomechanical characteristics of wheelchair propulsion in two groups of MWCU—a trunk flexion propulsion style group (FG) and a non-trunk flexion propulsion style group ...
