Protocol for strength testing and rehabilitation of the upper extremity.

The development of the upper body table (UBXT) provided trunk and pelvis stabilization, necessary for accurate testing of the strength (and power) of the upper extremity with the Cybex II(R) lsokinetic Dynamometer; however, a standard protocol for set-up and testing did not immediately exist in 1979. During treatment of patients with upper extremity problems, Sportclinic, Providence Medical Center, Seattle, Washington, developed a complete protocol for rehabilitation and testing with the Cybex II and the UBXT, using fast speeds, a 90-foot-pound torque scale, and special adaptations of equipment and procedure. The objectives of the protocol were to increase accuracy in testing and decrease the chance of injury to the patient J Orthop Sports Phys Ther 1983;4(4):229-235.
