Sung PS, et al. - This study aimed to investigate the symmetry index for limb support patterns in right limb–dominant older adults with and without low back pain (LBP). They recognized an asymmetrical gait pattern in patients with LBP, as they demonstrated a longer double-limb support pattern due to a possible pain avoidance strategy. Subjects with no LBP showed a symmetrical pattern for limb support in the stance phase. Clinicians were suggested to consider asymmetric limb support patterns of gait modification similar to the subjects with no LBP when developing rehabilitation strategies for patients with LBP.
