| Annotation | The neuropsychological, sensorimotor, speed and balance contributions to a new test of choice stepping reaction time (CSRT) were investigated, and determined whether this new test is an important predictor of falls in older people. 477 retirement village residents in Sydney, Australia aged 62 to 95 took the test, which required them to step into one of four panels that were illuminated in random order. Multiple regression analysis revealed that poor performance in Part B of the Trail Making Test (TMT, a neuropsychological test) and impaired quadriceps strength, simple reaction time, sway with eyes open on a complaint surface, and maximal balance range were the best predictors of increased CSRT. Those with a history of falls had a significantly increased CSRT compared with non-fallers. Impaired CSRT was a significant and independent predictor of falls, as were two complementary sensory measures (visual contrast sensitivity and lower limb proprioception). Of these measures, CSRT was the most important in predicting falls. The inclusion of CSRT in the model excluded measures of strength, central processing speed and balance, because these could not provide non-redundant information for the prediction of falls. (RH). |
