BACKGROUND AND PURPOSE Although there has been extensive research on the effectiveness of repetitive transcranial magnetic stimulation (rTMS) to improve patients' motor performance after experiencing chronic stroke, explicit findings on the coupling of different rTMS protocols are meager. We designed this sham-controlled randomized study to investigate the(More)
Degeneration in the neuromuscular system due to aging can affect daily activities that need to be controlled by bimanual coordination with both hands. However, little is known about the influence of aging on grip strength and bimanual coordination control between hands. The purpose of this study was to investigate the influence of aging on the maximum grip(More)
The purpose of this study is to register the 3D image from computed tomography (CT) and magnetic resonance (MR) and therefore to integrate the information of hard and soft tissue. The slices with maximum areas detected from both 3D data sets were used as the corresponding slices to calculate the parameters of scale, rotation and translation for 3D data(More)
We developed a mobility detection system to analyze pressure changes over time during side-turns in 29 healthy volunteers (17 males and 12 females) with a mean age of 46.1 ± 19.64 years (ranging from 23 to 86 years) in order to determine the effect of gender, age, and BMI on performance during bed postural change. Center of gravity (COG) location, peak(More)
The role of the vertebral body's rotation and the loading conditions of the brace has not been clearly identified in adolescent idiopathic scoliosis. This study aimed to implement a finite element (FE) model of C-type scoliotic spines to investigate the influence of different loading conditions on variations of Cobb's angle and the vertebral rotation. The(More)
PURPOSE The purpose of this study was to investigate the correlation of kinematic variables with quality of trunk control in poststroke patients. METHODS This cross-sectional study included stroke subjects with mild to moderate motor deficit corresponding to Brunnstrom stages 3-4. Trunk functional performance was measured using bed mobility monitor(More)
BACKGROUND AND OBJECTIVE Studies have already investigated vestibulo-ocular reflex (VOR) responses in elderly subjects, mostly at low frequencies (<1 Hz) during passive head turns, or continuous active head turns in a rotational chair. However, natural head movements usually occur at frequencies above 1 Hz and at varying rates, rather than at continuously(More)
OBJECTIVE We investigated the training effects of interlimb force coupling training on paretic upper extremity outcomes in patients with chronic stroke and analyzed the relationship between motor recovery of the paretic hand, arm and functional performances on paretic upper limb. DESIGN A randomized controlled trial with outcome assessment at baseline and(More)
BACKGROUND AND OBJECTIVE Ankle motion and proprioception in multiple axis movements are crucial for daily activities. However, few studies have developed and used a multiple axis system for measuring ankle motion and proprioception. This study was designed to validate a novel ankle haptic interface system that measures the ankle range of motion (ROM) and(More)
