Proprioception is essential for joint function and through which individual can detect body parts movement in space. Central nervous system can consciously and unconsciously adjust joint position with this information. Aim of present study is to investigate effect of balance training on unstable platform with tilting, translation and combined motion on knee joint position sense in active young males. 39 healthy active male participated in this experimental study and were divided in to four homogeny groups. Training on unstable platform with tilting motion group (n=10), Training on unstable platform with translating motion group (n=10), combined training group (n=10) and control group (n=9). The training groups performed 45 minutes exercises program for 8 weeks, three times a week and the control group continued with their normal workout routines. Errors in repositioning of knee joint in 30, 45 and 60⁰ angles (active and passive) was measured by Biodex system 3, before and after training period. Data was analyzed by using one way ANOVA test (P≤0/05). Although after 8 weeks, errors in repositioning of knee joint in 30, 45 and 60⁰ angles (active and passive) decreased in training groups but this difference was not significant (P≤0/05).Balance training on unstable platform (tilting, translating or combined of these two type of perturbation) alone cannot have a big effect on knee joint position sense in active young male.
