The influences of restricted compensatory movement on activation pattern of gluteal muscles during unilateral weight-bearing exercise

Abstract

We investigated changes in lateral pelvic tilt and activity of the gluteal muscles during one-leg standing with and without pressure biofeedback. Seventeen participants performed one-leg standing tests with pressure biofeedback (the threshold was set to the minimum change in pressure) and without biofeedback (standard one-leg standing). The lateral pelvic tilt was significantly lower in one-leg standing with pressure biofeedback than in standard one-leg standing (p < .05). In addition, gluteus medius and gluteus maximus activity was significantly greater during one-leg standing with pressure biofeedback than during standard one-leg standing (p < .05). Based on our results, restriction of compensatory movement can be used to increase activity of gluteal muscles when performing unilateral weight-bearing exercise such as one-leg standing.
