| Summary: | Background: The gluteus medius (Gmed) plays a critical role in maintaining frontal plane
stability of the pelvis during functional activities, such as one-leg lifting. Side-lying hip abduction
(SHA) has been used as a dynamic test to evaluate Gmed function. However, the
abduction force of the lower leg against the floor is not controlled during SHA. Therefore, hip
abduction performance with contralateral adduction in the side-lying position (HAPCA) can be
proposed as an alternative method to assess performance of hip abduction. If the number of
HAPCA is related to the lateral pelvic shift distance, a new quantitative measurement for hip
abductor function may be presented.
Objects: This study aimed to investigate the relationship between the number of successful
HAPCA and the lateral pelvic shift distance during one-leg lifting.
Methods: Thirty healthy participants were recruited, and lateral pelvic shift distance was
measured during one-leg lifting test using two-dimensional analysis. The number of successful
HAPCA was counted when participants touched both target bars at the beat of a metronome.
Results: There was a negative correlation between the number of HAPCA and lateral pelvic
shift distance during one-leg lifting (r = –0.630, p < 0.05). The number of HAPCA accounted
for 39.7% of the variance in the lateral pelvic shift distance during one-leg lifting (F = 18.454,
p < 0.001).
Conclusion: The number of successful HAPCA is significantly correlated with lateral pelvic
shift distance during one-leg lifting. This finding suggests that HAPCA can be proposed as a
new measurement for hip abductor performance and more research is needed on its relationship
with hip abductor strength. |
