Significant impact of joint restrictions on Δsagittal plane average positive hip power and pelvic list. In the sagittal plane we see increases in a subject averaged (N = 15) restricted limb Δaverage positive hip powers in the restricted-ank condition compared to the restricted-knee and restricted-a + k conditions. Error bars are mean ± s.e.m. In the frontal plane of the unrestricted limb we saw a decreased b subject averaged (N = 15) Δaverage positive hip power values in all conditions. Error bars are mean ± s.e.m. c subject averaged (N = 15) pelvic list was shifted upward in the swing phase in the restricted-knee and restricted-a + k conditions when compared to the when the knee was immobilized to accomplish foot circumduction without increasing frontal plane hip power. Black hatched lines were used for data calculated on the restricted limb in one of the three restricted conditions. Asterisks indicate a statistically significant difference (post-hoc paired t-test with Bonferroni correction for multiple comparison, p < 0.05)
