Figure 5.

Group bar graphs of gluteus medius electromyography (EMG) onset and peak latency. For gluteus medius onset latency (top 4 graphs), there were significant (P < 0.001) main effects of Myelopathy, Pull Magnitude, Stance, and Predictability. For gluteus medius peak latency (bottom 4 graphs), there was a significant (P < 0.001) Pull Magnitude × Stance interaction and main effects (P ≤ 0.002) of Myelopathy, Magnitude, Stance, and Predictability. PwDCM, people with degenerative cervical myelopathy; SW, shoulder width.
