Evaluation of proprioception of wrist in the cases of the hemiplegia after cerebro vascular event (CVE) by using isokinetic system

Abstract

Objective: Evaluation of proprioception of the wrist in cases of hemiplegia after a Cerebro Vascular Event (CVE) using isokinetic systems and improving the proprioception with the aid of these systems. Materials and Methods: Seventy-five patients with hemiplegia after CVE and 50 healthy control subjects were included in this study. Assessments were made in the affected hand of the patient group and in the dominant hand of the control group by using a computed isokinetic dynamometer. Passive joint position sensation in the wrist was measured by using computerised isokinetic dynamometer as target angle 15° extension with 2°/sec angular velocity, 15° flexion with 2°/sec angular velocity and 20° extension with 45°/sec angular velocity. Three measurements were made for each target position in the patient and control groups. The average of three measurements were obtained (test 1, 2, 3). Results: There were statistically significant differences between groups in test 1, test 2 and test 3 with respect to failure rate of joint position sensation (p<0,05). Conclusion: Proprioception, especially sense of joint position, is necessary in daily activities such as grasping and releasing. The diagnosis of loss of proprioception is important for both the clinician and the patient, because this affects rehabilitation programme and can explain the failure of the patient's response to treatment.
