Changes in abdominal muscle thickness measured by ultrasound are not associated with recovery in athletes with longstanding groin pain associated with resisted hip adduction

Abstract

There was no association between changes in abdominal muscle resting thickness and relative thickness during lower extremity tasks, and change in self-reported sports restriction after a period of physical therapy in athletes with longstanding groin pain associated with resisted hip adduction. Although this study was designed as a single-cohort longitudinal study, the data suggest that the intervention described can change TA resting thickness. The intervention did not influence abdominal muscle relative thickness during lower extremity tasks
