Abstract 

Objective

The purpose of this study was to investigate correlation during concurrent measurement among three knee joint position sense (JPS) measures in sitting position and between two measures in standing position.

Methods

Isokinetic dynamometer, electrogoniometer, and two dimensional (2D) video analysis were used for measuring knee JPS. The JPS was measured both in sitting and standing positions. All three measures were employed concurrently to measure knee JPS in sitting position; however, only the electrogoniometer and 2D video analysis were concurrently used in the standing position. The knee JPS was recorded in sitting position at 15°, 30°, and 45° and in standing at high, mid and low knee flexion positions.

Results

The results of the study suggest excellent correlation (0.94–0.98) between the electrogoniometer and 2D video analysis measures in standing position. In sitting position, good to excellent correlation (0.63–0.92) was found between the isokinetic dynamometer and electrogoniometer; however, fair to good correlation was found between 2D video analysis and either of the two measures (electrogoniometer [0.52–0.57] and isokinetic dynamometer [0.41–0.63].

Conclusion

Either 2D video or an electrogoniometer may be used to measure JPS in standing position; however, in sitting position 2D video should not be used if the camera is required to be placed at 10° from the plane of motion.
