Optimal application of the N-k table as an exercise device for knee extension*

, : Optimal application of the N-k table as an exercise device for knee extension*. Journal of Orthopaedic and Sports Physical Therapy 8(4): 189-192

The purpose of this study was to determine the optimal position of the N-K table* resistance arm relative to the exercise arm which might best match the biomechanics of the knee extensor musculature and serve to improve the use of the N-K table in rehabilitation of the injured or painful knee. First, torque-position relationships were derived for the knee extensors of six subjects using a computer controlled dynamometer (KinlCom). section sign Next, relative torque-position relationships were established for four different N-K table resistance arm offsets using the dynamometer (KinlCom) as a robotic device to push the exercise arm of the N-K table through the range of motion while recording the torque. Different torque position relationships were recorded when the offset was 10, 55, 80, or 100 O from the exercise arm. The 55 O offset appeared optimal for most knee extension exercises. However, other resistance arm offsets tested could be useful in rehabilitation of specific knee problems. J Orthop Sports Phys Ther 1986;8(4):189-192.
