[Purpose] The purpose of this study was to investigate the influence of the rotational axis position of a reclining wheelchair's back support on fluctuations in the shear force applied to the buttocks while the back support is reclined. [Subjects] The subjects were 12 healthy adult men. [Methods] The shear force applied to the buttocks was measured using a(More)
Our previous single-pulse transcranial magnetic stimulation (TMS) study revealed that excitability in the motor cortex can be altered by conscious control of walking relative to less conscious normal walking. However, substantial elements and underlying mechanisms for inducing walking-related cortical plasticity are still unknown. Hence, in this study we(More)
PURPOSE The purpose of this study was to investigate the mechanism of the fluctuation in the shear force applied to the buttocks. METHOD The subjects were 11 healthy adult men without leg or trunk diseases. The amount of force applied to the buttocks was measured by using a force plate, and a pressure and shear force sensor was used to measure the timing(More)
To explore the effects of qualitative or quantitative changes in walking on motor cortical excitability, a transcranial magnetic stimulation procedure was used to examine the alterations of motor-evoked potential (MEP) amplitude following walking. Eight healthy participants completed a series of two walking tasks on a treadmill at 2 km/h. The ratio of the(More)
[Purpose] The purpose of this study was to investigate the effect of the timing of leg support elevation on the horizontal force acting on the buttocks in a reclining wheelchair. [Subjects and Methods] The participants were 17 healthy men. Two experimental conditions were tested: the leg-down and leg-up conditions. The back support was reclined at(More)
OBJECTIVE The purpose of this study was to investigate the most suitable site and method to effectively generate isometric hip flexion torque (torque value) using transcutaneous electrical or magnetic stimulation. DESIGN Eleven healthy volunteers underwent torque value and pain degree measurements during magnetic stimulation of the iliopsoas using three(More)
PURPOSE The purpose of this study was to investigate the influence of the distance between the position of the rotation axis of the back support and hip joint on the changes in the shear force applied to the buttocks. STUDY DESIGN Repeated-measures design. METHODS The subjects were 11 healthy adult men without leg and/or trunk diseases. The shear force(More)
PURPOSE The purposes of this study were to construct a real-time acceleration gait analysis system equipped with software to analyse real-time trunk acceleration during walking and to examine the intra-rater and inter-rater reliabilities of the this system. METHODS This system has been comprised of an accelerometer, an acceleration amplifier, a(More)
BACKGROUND Studies have not been conducted to investigate the influence of the height of the rotational axis of a wheelchair's back support on the shear force applied to the buttocks during the reclining motion. OBJECTIVES The purpose of this study was to investigate the influence of the difference in the rotational axis position of back support in the(More)
Purpose: The purpose of this study was to investigate how the influences of leg support elevation on the horizontal force acting on the buttocks in a reclining wheelchair changes in various rotational axis positions of the back support. Materials and methods: The participants were 13 healthy men. The horizontal force was measured using a force plate on the(More)
