Effectiveness of training somatosensation in the hand after stroke: A randomized controlled trial.

Funded Activity Summary

Stroke is a leading cause of death and disability, requiring provision of rehabilitation services to help minimize impairment and its impact on the ability to resume daily activities. The ability to feel textures and objects through touch and to know where one s limbs are in space are impaired in up to 85% of people who have suffered a stroke. People with this loss are handicapped by difficulties in exploring objects through touch and in performing everyday tasks that require grasp and manipulation of objects. Yet clinicians are either not treating the problem or are using methods without a sound theoretical basis and controlled evidence to support their application. We have systematically investigated optimal methods of sensory training across different sensory abilities using a series of single-subject experiments. Marked improvement in the ability to discriminate trained and related untrained texture stimuli and limb positions was achieved and maintained in most participants. These findings have provided the foundation for development a scientifically based and clinically focused sensory retraining program that has apparently excellent therapeutic potential. The purpose of the proposed study is to test the effectiveness of this scientifically based, clinical sensory retraining program in a broad group of stroke clients using the internationally recommended randomized controlled group design. The program will train a range of functionally important sensory discrimination tasks, i.e. texture discrimination, limb position sense and tactual object recognition, in clinical and home environments. Demonstration of clinically important and statistically significant training effects will provide the evidence necessary to recommend the introduction of the program into routine health service delivery. Investigation of patient characteristics that may impact on the ability to benefit from training will assist in the targeting of services to appropriate individuals.
