The effect of Hamstring and Calf Tightness on Static, Dynamic Balance and Mobility - A Correlation Study
Subscribe/Renew Journal
Objective: The study is intended to find correlation between calf tightness and hamstring. Tightness with static, dynamic stability and balance in adult population.
Method: 30 subjects between age group of 40-60 yr were selected. Tightness of calf and hamstring were measured. The calf tightness was measured by taking difference between active and passive dorsiflexion range. The hamstring tightness was measured by using AKET. Following outcome measures were taken to find the correlation with the tightness.
Outcome measures:
1) Functional Reach Test for static stability (Forward & Backward Reach)(FRT)
2) Time Up and Go test for mobility(TUG)
3) Berg Balance Scale for balance (BBS)
Study design: Experimental randomized clinical trial
Sampling technique: Purposive random sampling from adult population
Results: The data was analyzed by using Pearson correlation (2-tailed) technique. The hypothesis is accepted and thus it suggests that there is correlation between tightness, balance and mobility. Hamstrings and calf tightness shows highly positive correlation with TUG (r for hams and TUG = 9.45, r for calf and TUG =8.62) and highly negative correlation with FRT and BBS (r for hams and FRT, forward= -8.10, r for hams and FRT, backward = -7.75, r for hams and BBS = -7.06, r for calf and FRT, forward -9.62,r for calf and FRT, backward = -8.96, r for calf and BBS = -9.25).
Conclusion: Hamstrings and calf tightness shows highly positive correlation with mobility and highly negative correlation with static dynamic balance. Therefore the present study suggests that the correlation exists between tightness, static, dynamic balance and mobility.
