Abstract

Background: Single leg stance (SLST) and Single leg squat (SLSQ) are functional tests that are commonly used to evaluate hip abductor performance. The previous studies found that SLST and SLSQ testing in person with hip abductor weakness may not always exhibit the lateral pelvic drop. There are a few studies regarding the relationship between hip muscle strength and lateral pelvic drop during SLST and SLSQ that were still unclear.


Objective: To investigate the relationship between each hip abductor muscle (HABD) strength and pelvic obliquity angle (PO), Thoracic obliquity angle (TO) during SLST and SLSQ.


Methods: Fifty healthy males and females, aged 20.6±1.4 years, were measured HABD strength including gluteus maximus (GMax), gluteus medius (GMed) and tensor fascia latae (TFL) by hand-held dynamometer (HHD). Kinematic data were collected by using motion analysis system during SLST and SLSQ.


Results: During SLST, there were only significant correlations (p<0.05) between GMax and TO (r=   -0.397), TFL and TO (r= -0.393), but there was no significant correlation between HABD strength and TO during SLSQ.


Conclusion: There was no significant correlation between three HABD strength and PO during SLST and SLSQ. It was possible that the HABD strength of all participants in the current study may be similar.
