Comparison of muscle activity ratio in the GMp/TFL and GMm/QL among PD, PDE, and PDF
Variable | Muscle activity ratio | 95% CI | |||||
---|---|---|---|---|---|---|---|
PD | PDE | PD | PDE | ||||
GMp/TFL | 1.9 ± 1.3 | 0.9 ± 0.5 | 2.1 ± 1.5 | 1.3–2.5 | 0.7–1.1 | 1.4–2.7 | |
GMm/QL | 1.1 ± 1.0 | 0.9 ± 0.8 | 0.9 ± 0.7 | 0.7–1.6 | 0.6–1.2 | 0.6–1.2 |
Values are presented as mean ± standard deviation or number. GMp, posterior subdivision of gluteus medius; TFL, tensor fasciae latae; GMm, middle subdivision of gluteus medius; QL, quadratus lumborum; PD, pelvic drop exercise; PDE, pelvic drop exercise with an isometric hip extension of non-weight bearing leg; PDF, pelvic drop exercise with an isometric hip flexion of non-weight bearing leg; CI, confidence intervals.
