[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-thick lumbar pad, and a 6-cm-thick lumbar pad. The instruments used for measurement were used two accelerometers. The participants were asked to propel their wheelchairs, which had been equipped with two accelerometers, 30 times. [Results] The intensity of muscle movement with the 3-cm-thick lumbar pad was significantly lower than the intensities with no lumbar pad and the 6-cm-thick lumbar pad. The muscle intensity did not differ significantly between the no pad and 6-cm-thick lumbar pad conditions. [Conclusion] An appropriately thick backrest has good effects on upper arm and trunk muscles during wheelchair propulsion. In the future, we must consider the appropriate backrest thickness for providing wheelchair users with a comfortable wheelchair.

[Purpose] The purpose of this study was to show the effects of the wearing of tight jeans on lumbar and hip movements during trunk flexion. [Subjects] Twelve male subjects were recruited. [Methods] The lumbar flexion angle and hip flexion angle were measured using a dual inclinometer during trunk flexion, with and without tight jeans. [Results] The lumbar flexion angle significantly increased when wearing tight jeans compared to not wearing and wearing of general jeans. The hip flexion angle significantly decreased when wearing tight jeans compared to not wearing and wearing of general jeans. [Conclusion] We suggest that tight jeans might limit normal lumbar and hip movements. So, abnormal lumbar and hip movements induced by tight jeans may be a cause of low back musculoskeletal disorders.
