Abstract

The goal of this research was to measure the correlation between hip flexor extensibility, arabesque height, and lower back pain; specifically, whether a tight iliopsoas group restricts range of motion and correlates with lower back pain in dancers. Through a series of non-invasive measurements, the rectus femoris and iliopsoas group were tested for range of motion and general extensibility. The measurements were as follows: Patrick’s Test, Thomas’s Test, Modified Thomas Test, and prone hip hyperextension. Each subject also completed a pre-screening form to assess degree of lower back pain. The outcomes of the measurements were analyzed to find a possible correlation between hip flexor extensibility, hip hyperextension (arabesque height), and lower back pain.
