Long-term effects of auditory feedback training on relearned symmetrical body weight distribution in stroke patients. A follow-up study
Department of Physical Therapy, Karolinska Institute, Huddinge, Sweden
Long-term effects of auditory kinetic feedback on relearned symmetrical body weight distribution while rising and sitting down were studied in stroke patients. Thirty patients were re-tested on average 33 months after having trained with and without auditory feedback. Body weight distribution on the legs was measured with two force plates. At re-test there was a decrease from 48% to 39% of body weight distribution (%BWD) on the paretic leg in rising and in sitting down in the patients in the auditory feedback group (p < 0.001). In the control group the decrease was from 44 to 39% BWD on the paretic leg (p < 0.05) in rising and from 44 to 42% BWD (n.s.) in sitting down. The symmetrical body-weight distribution, acquired after auditory feedback training, was not consistent over time. Movement time, however, was significantly reduced in the auditory feedback group (p < 0.05). Possible reasons for the findings are discussed.
