Brief Summary:
This study aimed to assess correlations between muscle tone, stabilization of the trunk and the upper extremity, and parameters of hand/wrist motor coordination in post-stroke patients and neurologically healthy subjects with lower back pain.
Detailed Description:
A Luna electromyography (EMG) (EGZOTech) was used to measure muscle tension, and a manual electronic dynamometer (EH 101) was used for grip strength measurement (error of measurement, 0.5 kg/lb). A Hand Tutor device (composed of a safe and comfortable glove equipped with position and motion sensors, and the Medi Tutor (TM) software was used to measure the range of passive and active movement, as well as the speed/frequency of movement. The Hand Tutor glove was worn on the hand of the directly affected side in stroke patients and on the dominant extremity in patients with pain syndrome. Surface electrodes (single-use 55' and '40 mm; ECG Electrodes; limited liability company and limited partnership (Sorimex), Poland were affixed to the subject's body according to the SENIAM (Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles) procedure on the transverse abdominal, multifidus, and supraspinal muscles (on the side directly affected in stroke patients, and on the dominant side in patients with back pain syndrome). Before each exercise, the subject was instructed on how the exercise should be done.
The examination 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 upper limb was stabilized at the subject's body (adduction in the humeral joint, elbow flexion in the intermediate position, wrist and hand free).
In each of the starting positions, after putting the glove on, the range of passive movement in the radial-carpal joint (flexion and extension) and fingers (global flexion and extension) was measured. Then the subject made active movement in the same order. Finally, 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 speed or frequency tests.
First, the range of passive movement in the radial-carpal joint (flexion and extension) and fingers (global flexion and extension) was measured in each position (sitting or supine) using the Hand Tutor Device. Then the subject made active movements in the same order. Finally, the subject was asked to make moves as quickly and in as full a range as possible. The measurement of grip strength with a dynamometer was performed in both positions (sitting or supine) after the range of motion and speed/frequency tests. The reaction of the examined multifidus, transverse abdominal, and supraspinatus muscles (tension values reported in microvolts (µV) was also assessed during each of the exercise tasks using the surface electrodes (i.e., during movement of the wrist and during movement of the fingers).
