| Research Abstract |
1. Relationship between balance function and ambulatory ability in elderly and hemiplegia
We assessed the walking ability and balance function using maximum walking speed (MWS), functional reach test (FR) and timed up & go test (TUG), and also evaluated the postural sway using a stabilimeter, in 25 young and 24 older normal adults. Compared with young adults, older adults exhibit worse postural balance and bigger postural sway. We found significant relationships among MUS, FR and TUG in older adults. The results of this study showed that the walking ability in the elderly was affected by the static and dynamic balance functions.
Thirty six post-stroke patients who could walk and 37 age-matched healthy individuals were recruited. We measured the change of center of foot pressure (COP) and MWS. The relationships between the static balance function and degree of paresis, ADL or the ambulatory ability were examined. The static balance function in hemiplegia was inferior compared to healthy individuals. Significant relationships between the static balance function and the ambulatory function or ADL were seen in hemiplegia. This study suggests that the static balance function influences ambulatory ability and ADL in hemipegia.
2. Evaluation of dynamic balance function using stepping-in-place on stabilimeter Stepping-in-place (free step, 100 steps per minute and maximum step) on a stabilimeter were conducted for 66 healthy subjects, and the change of COP, floor reaction force, a walking cycle were measured. The postural sway and the variation of COP and floor reaction force,became larger in the maximum step compared with the free step. The postural sway and the variation became larger with aging. The stance phase became shorter and the swing phase became longer with aging. It was suggested that the method in this study was applicable to evaluation of the dynamic balance function.
