Effect of system tilt and seat-to-backrest angles on load sustained by shoulder during wheelchair propulsion.
This study determined the effect of system tilt angle (STA) and seat-to-backrest angle (SBA) changes on the load sustained by the shoulder during manual wheelchair propulsion. Fourteen elderly participants (mean +/- standard deviation age 68.2 +/- 5.2 years) were recruited. Combinations of three STAs (0 degrees , 5 degrees , and 10 degrees ) and three SBAs (95 degrees , 100 degrees , and 105 de...
متن کاملThe effects of backrest thickness on the shoulder muscle load during wheelchair propulsion
[Purpose] This study investigated the optimal thickness of the wheelchair backrest for lumbar load and increased comfort. [Subjects] Fifteen healthy people participated. [Methods] The study examined three randomized backrest conditions: no pad; a 3-cm-thick lumbar pad; and a 6-cm-thick lumbar pad. The location of the lumbar pad was standardized at the mid-lumbar level (L3). Participants were in...
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 کاملBiomechanics of manual wheelchair propulsion in elderly: system tilt and back recline angles.
OBJECTIVE To investigate the effects of the system tilt and back recline angles on the biomechanics of wheelchair propulsion for a group of older, disabled patients. It was hypothesized that increasing both the system tilt and backrest recline angles would have a positive effect on the biomechanical efficiency of manual wheelchair propulsion. DESIGN Three kinetic variables were estimated duri...
متن کاملA study on effects of backrest thickness on the upper arm and trunk muscle load during wheelchair propulsion
[Purpose] The purpose of this study was to investigate the effects of the thickness of a wheelchair backrest provided for support and comfort on upper arm and trunk muscle load during wheelchair propulsion by using accelerometers. [Subjects and Methods] The Fourteen healthy participants were enrolled in this study. The study compared effects of three backrest conditions including no pad, a 3-cm...
