Force Control of Elbow and Shoulder during Isometric Contraction in Hemiparetic Stroke Patients / 中国康复理论与实践

ABSTRACT

Objective To evaluate the ability of force control of elbow and shoulder during isometric contraction in patients with chronic stroke. Methods From January to December, 2015, 22 chronic stroke patients and 12 healthy people were measured the maximum force dur-ing shoulder abduction/adduction and elbow flexion/extension with instrument for measuring force of upper extremity. The coefficient of variation was calculated. Results The maximum force was less in the patients than in the healthy controls (t>2.349, P1.974, P<0.05), except those of elbow extension. Conclusion The force measure and the coefficient of varia-tion can reflect the force control in shoulder and elbow motion in stroke patients.
