Measurement of Kinesthetic Sensitivity by Joint Angle Reproduction and Threshold for Lifted Weights

Abstract

Abstract Thirty college women were given 24 trials on a joint position reproduction task for the right arm and 24 trials on a joint position reproduction task for the right leg. Split half reliability, interindividual variability, and intra-individual variability were computed for each task. The reliability for the arm positioning was .860 and for the leg positioning .892. For both tasks, the intra-individual variability was greater than the interindividual variability. The relationship between the two tasks was negligible. The difference limen for lifted weights was determined for the right hand and the right foot. The first day the subjects were given two descending and two ascending series of comparison weights on each task. Two weeks later they were retested. The test-retest reliabilities were low (.225 for the right hand and .440 for the right foot).
