Summary

This study aimed to assess how stabilization of the trunk and the upper extremity can change the parameters of hand/wrist motor coordination and grip strength in dominant and non-dominant paretic upper limb, in post-stroke patients and neurologically healthy subjects.

Detailed description

The examination of the dominant and non-dominant paretic hand consisted of two motor tasks, carried out in two different starting positions: sitting and lying down (supine). During the first examination, the subject sat on the therapeutic table (without back support), feet resting on the floor. The upper limb was examined in adduction of the humeral joint, with the elbow bent in the intermediate position between pronation and supination of the forearm, with free wrist and the hand. In the supine position, the affected upper limb was stabilized at the subject's body (adduction in the humeral joint, elbow flexion in the intermediate position, wrist and hand free). The Hand Tutor device and an electronic hand dynamometer were used for the measurements. In each of the starting positions, after putting the glove on (using the Hand Tutor Device), the subject was asked to make moves as quickly and in as full a range as possible. Finally, the measurement of grip strength with a dynamometer was performed in both analyzed starting positions, after completing the range of motion and frequency tests.
