| Introduction: Impaired postural control affects the safety and quality
of movements during daily life activities and physical exercises. One of the
effective factors on postural control is the muscle flexibility. Despite the
relative high incidence of hamstring shortness, no study has yet evaluated the
relationship between hamstring shortness and dynamic and static balances. The
aim of this study was to investigate the relationship between hamstring
shortness and dynamic and static balances in young healthy individuals. Materials and Methods: This cross sectional study was carried on 40 healthy
young subjects (20 cases with and 20 cases without the shortness of hamstring
as control). The 90-90 test was used to measure the hamstring length. To evaluate
the quality of balance control, subjects stood on a force plate and Biodex
system on one foot and level of displacement of centre of pressure was used as
an index of static and dynamic balances, with and without external
perturbation. Results: The comparison of mean and standard deviation of the
center of pressure displacement with and without external perturbation, showed
no significant difference between the two experimental and control groups. Conclusion: The results of present study showed that the hamstring
shortness does not significantly affect the static and dynamic postural balance
control. |
