BACKGROUND: Trunk control impairment often accompanies multiple sclerosis (MS). Trunk stability is necessary for movements of extremities, as are selective trunk movements for normal gait. Measuring trunk function is thus of interest. METHODS: We examined the relationships between the Trunk Impairment Scale (TIS1.0 and TIS2.0) and the Berg Balance Scale (BBS), 5 sit-to-stand test (5STS), Timed Up and Go test (TUG), 10-m timed walk test (10TW), 2-min walk test (2MWT), Falls Efficacy Scale - International, and 12-item MS Walking Scale (MSWS-12) in 47 outpatients...

Parkinson's disease (PD) is a neurological disorder associated primarily with motor symptoms such as tremor, slowness of movement, and difficulties with gait and balance. Most patients take dopaminergic medication to improve their motor functions. Previous studies reported indications that such medication can impair higher cognitive functions (cf. dopamine overdose hypothesis). In the present study, we examined the effect of medication status on conflict adaptation. PD patients performed a Stroop task in which we manipulated the proportion of congruent and incongruent items, thereby allowing us to explore conflict adaptation...

The aims of this study were to identify static and dynamic balance with the addition of weighted vests for the rehabilitation of paraplegic patients. The study was conducted using weighted vest exercises with applied optimal weight ratios. Ten paraplegic patients who use custom orthosis were enrolled for experiments including static standing and dynamic gait with a weighted vest. We set weight ratios as 0%, 10%, and 15% of the patients' weight. A plantar pressure device was used for static balance tests for excursion and velocity of center of pressure and we identified dynamic balance through the tool of Timed Up and Go (TUG) test...

Preferred walking speed (PWS) reflects the integrated performance of the relevant physiological sub-systems, including energy expenditure. It remains unclear whether the PWS during over-ground walking is chosen to optimize one's balance control because studies on the effects of speed on the body's balance control have been limited. The current study aimed to bridge the gap by quantifying the effects of the walking speed on the body's center of mass (COM) motion relative to the center of pressure (COP) in terms of the changes and directness of the COM-COP inclination angle (IA) and its rate of change (RCIA)...

Restoring functional gait speed is an important goal for rehabilitation post-stroke. During walking, transferring of one's body weight between the limbs and maintaining balance stability are necessary for independent functional gait. Although it is documented that individuals post-stroke commonly have difficulties with performing weight transfer onto their paretic limbs, it remains to be determined if these deficits contributed to slower walking speeds. The primary purpose of this study was to compare the weight transfer characteristics between slow and fast post-stroke ambulators...

Motion capture setups are used in numerous fields. Studies based on motion capture data can be found in biomechanical, sport or animal science. Clinical science studies include gait analysis as well as balance, posture and motor control. Robotic applications encompass object tracking. Today's life applications includes entertainment or augmented reality. Still, few studies investigate the positioning performance of motion capture setups. In this paper, we study the positioning performance of one player in the optoelectronic motion capture based on markers: Vicon system...

BACKGROUND: In the 10 most populated countries in the world, Parkinson's disease (PD) affects more than 5 million individuals. Despite optimal treatment options already developed for the disease, concomitant involvement of other areas of health care plays an important role in complementing the treatment. From this perspective, dancing can be viewed as a non-drug alternative that can reduce falls by improving some motor skills, such as mobility, balance, gait, and posture, and can also improve the overall quality of life...
