Introduction: 

Low back pain (LBP) is the leading cause of disability worldwide (1). A growing body of research is demonstrating a correlation between myofascial pain, myofascial trigger points, weakness and altered recruitment patterns of the hip abductor musculature and LBP (2-10). This 2015 study by U.S. researchers demonstrates that chronic non-specific LBP was most strongly correlated with ipsilateral gluteus medius weakness and gluteal tenderness, and also correlated with ipsilateral erector and trochantric tenderness and greater strength of the contralateral tensor fascia latae. Human movement professionals working with individuals with LBP should consider assessing these issues and addressing any noted impairments as part of a comprehensive treatment plan.
