Gluteus medius weakness and chronic low back pain

Gluteus medius weakness in chronic low back pain compared to healthy controls

Hip abductor weakness is often seen clinically in patients with chronic, non-specific low back pain (CNSLBP). The current study aimed to assess differences in gluteus medius, maximus and TFL strength between subjects with CNSLBP and healthy subjects.  Manual muscle tests were used to determine strength with the 1-5 strength scale. The authors found a significant difference in strength between the groups, particularly on the affected side in subjects with unilateral pain. There was also a significant correlation between unilateral low back pain and trendelenburg sign.

Although a small study by Kendall et al in 2010 found a reduction in LBP of 48% after 3 weeks of gluteus medius training, future studies should rigorously examine the effect of gluteus medius strengthening in this subgroup of CNSLBP patients and should include assessment via dynamometer.
