Computer-Assisted Evaluation of Hand and Arm Function After Thermal Injury

Abstract

Comprehensive care of the burned upper extremity requires accurate and complete evaluation of function, including two-point discrimination, active and passive range of motion, and grip strength. These evaluations, when performed serially during a course of therapy, are time-consuming and manpower-intensive. We tested the utility and accuracy of a commercially available computer-assisted impairment evaluation system when used to automate and standardize measurement of upper-extremity function. The function of 80 upper extremities was evaluated with both the conventional and the computer-assisted methods. The time required to perform a complete examination with each method was recorded, and measurements of grip strength and total active motion made with both methods were compared. Complete upper-extremity evaluation required an average of 20.3 minutes with the computer-assisted method, compared to 62.9 minutes with conventional means. Measurements of extremity function with computer-assisted and conventional methods had correlation coefficients of 0.984 for grip strength and 0.996 for total active motion. The computer-assisted impairment evaluation system was found to be a useful and accurate adjunct in the acute and rehabilitative management of burned upper extremities.
