Anterior hip or groin pain is a common complaint for which people are referred
for physical therapy. We have observed that people with anterior hip pain often
walk in greater hip extension than people without anterior hip pain, and that the
pain is reduced when they walk in less hip extension. Therefore,
we investigated
anterior hip joint forces which may contribute to anterior hip pain and examined
the effect of end range hip extension on the anterior hip joint force during
gait. To do this, we used a 6 degree of freedom, three-dimensional
musculoskeletal model to estimate hip joint forces during gait. Within subjects,
the maximum anterior hip joint force for gait trials with the most hip extension
was compared to the anterior hip joint force for gait trials with the least hip
extension. The musculoskeletal model indicated that increasing the maximum end
range hip extension when walking results in an increase in the anterior hip joint
force when compared to walking in less hip extension. Walking in greater hip
extension may result in an increase in the anterior hip joint force, and thereby
contribute to anterior hip pain.
The findings of this study provide some evidence
supporting the use of gait modification to reduce anterior hip force when
treating people with anterior hip pain.
