Objective: To evaluate the components for vocational rehabilitation program including the strengths and job simulation, and to provide the data of the upper extremity strengths for a successful return to work.
Method: Sixty normal untrained subjects(male 30, female 30) were examined for the grip and pinch strengths using Jamar dynamometer and Preston pinch gauge, and the strengths of five simulated tasks using work simulation of Cybex 6000 Testing and Rehabilitation System(Cybex, Division of Lumex, inc., USA).
Results: The values during the tasks were significantly different in males compared to females(p＜0.01). Strengths of the right upper extremity by Jamar dynamometer, Preston pinch gauge, gripping device, T-handle(radial direction), and flutted knob(radial direction) were significantly different compared to the left(p＜0.01). Grip strengths between Jamar dynamometer and gripping device of Cybex were highly correlated(p＜0.01). All the measured values were significantly correlated with both weight and height(p＜0.01).
Conclusion: The results of this study can be used as a baseline data for the vocational rehabilitation in patients with a disability of upper extremity.
