Implementation of an On-Line lsokinetic Analysis System.

A cost effective and efficient means of obtaining torque, work, and power measurements for a large group of subjects was needed. As a solution to this problem, an Apple 111 microcomputer was interfaced to a Cybex II isokinetic dynamometer. This system provided instantaneous values for the three parameters listed above as well as additional options for filekeeping and data manipulation. Intraclass reliability coefficients for the parameters of torque, work, and power ranged from r = 0.991 to r = 0.999. It was concluded that a microcomputer support system is, in view of its time saving qualities and relative cost, an economical and efficient means of providing meaningful information for clinical analysis of patients.
