Hamstring Kas Kısalığının Diz Eklemi Proprioseptif Duyusuna Etkisi

Abstract

The effect of hamstring muscle shortening sense of proprioception was investigated in this study. 61 healthy subjects participated in our study. Subjects with hamstring tightness were randomly divided into two groups (Group 1 and Group 2) and subjects without hamstring tightness were included in Group 3. Passive static stretching exercises were applied to first group 5 days per week for 6 weeks, 30 seconds for 6 repetitions each day. The subjects in the second and third group were assessed without any intervention. Subjects' hamstring muscle length measurement was evaluated with active knee extension method, proprioception (the active joint position sense and coordination) tests with Monitored Functional Squat System tool at first day, 3 and 6 weeks. The first group of active knee extension values in 3rd and 6th weeks were significantly increased according to other groups' values (p <0.05). When the groups were compared in terms of active joint position sense, there was no significant difference intra-group inter-group values in 3rd and 6th weeks (p> 0.05). The significant increase was seen the coordination values of subjects in all groups, while no difference was seen between in the groups. Based on these results, it was observed that hamstring muscles shortening did not affect to the sense of knee joint proprioception. Owing to improvement in coordination sense that did not mention previous studies about proprioception for all groups, it was concluded that coordination was a proprioceptive skill easily learned and it could be useful to prefer primarily for proprioception studies.
