Assessment of proprioception is valuable for identifying proprioceptive deficits. There are several methods to assess the prop-rioception. Joint position sense can be assessed in weight bearing (WB) and non weight bearing (NWB) position of the limb whose joint is to be tested. Aim and Objectives: To find out the difference in joint position sense in NWB and in WB positions in normal subjects. Material and Methods: 40 normal healthy subjects between the age group of 20 to 25 years were selected.

Right knee joint proprioception at 30 0 knee flexion was measured using non weight bearing and weight bearing methods by active test with epsilateral active limb matching response. The knee joint position sense was measured by universal Goni-ometer. Average of 3 response angle was taken as the final reading. Two assessment procedures were compared with Mann-Whitney Test. Position sense accuracy was measured as a relative error. The relative error was calculated as an arithmetic difference between test and response positions. A measure of variability of individual observation was calculated by SD and coefficient of variation Results: Present study shows that there is a significant difference in two assessment procedures while testing joint
