Increasing functional communication through relaxation training and neuromuscular feedback.

The following research examined the effects of behavioural relaxation training and biofeedback on ataxic tremor of an adult with acquired brain injury. The participant was taught relaxation techniques before biofeedback was introduced. Once he was proficient in relaxation, these skills were then used as a foundation for biofeedback training. Specific skills, facilitating the use of a letter board, were taught when the participant was able to relax the appropriate musculature to criterion. The results demonstrated that the participant learned how to significantly decrease the severity of tremor. As a result, he became more proficient at communicating via his letter board. Collateral effects were increased attempts at communication and fewer episodes of anger.
