BRIEF REVIEW: Hip & Lumbar Range of Motion and Lower Back Pain


Most musculoskeletal injury is multifaceted, with biomechanics, i.e. the way we move, one potential aspect that may lead to the occurrence of either a gradual-onset or acute-onset injury. It is thought that suboptimal biomechanics (tightness, weakness, impaired motor control etc.) in certain areas of the body may lean to increased mechanical load in other areas. 

The prevalence of lower back pain in judo athletes has been reported to be as high as 62% (1). The sport requires a high volume of rapid rotation, particularly into internal rotation of the hip of the supporting leg. Decreased hip rotation range of motion has been associated with lower back pain in adolescent judoka (2), as well as in other rotational sports such as golf (3). The aim of this study was to determine a link between hip, as well as lumbar spine range of motion and back pain in adult judo athletes 


62 judo athletes aged between 18-40 years (average age 25) with an average of 16 years judo experience, were grouped according to whether (29) or not (33) they had experienced ongoing lower back pain over the previous 6 months. The back pain group reported an average of 31/100 in terms of pain levels. All athletes underwent measurement of hip internal rotation and external rotation, as well as lumbar flexion and extension.


Athletes with lower back pain had on average 7 degrees less passive and active internal rotation on their non-dominant side, 8 degrees less lumbar flexion and 6 degrees less lumbar extension that the non-lower back pain controls.


Given the correlation between lack of hip range of motion and lower back pain in this cohort there may be a role for screening of this area in judo athletes, and where necessary, including interventions to optimise this quality in strength and conditioning programs and warm-up routines. 

The reduced lumbar range of motion may be causative of the back pain seen in these subjects, but may also have been caused by fear avoidance, muscle guarding, and impaired motor control secondary to their pain. Therefore, judo athletes experiencing lower back pain should have the condition investigated to identify the likely cause.
