Shoulder abduction

1. Shoulder abduction increases intermuscular coherence in humans (F = 22.4, p = 0.0007).

   “there was a significant effect on IMC due to shoulder posture in the alpha-band ( F = 22.4 , p = 0.0007 ), beta-band ( F = 44.6 , p = 5 × 1 0 - 5 ), and gamma-band ( F = 57.9 , p = 4 × 1 0 - 6 )”

   Intermuscular coherence during arm movement changes significantly with shoulder abduction and age, but not with limb dominance
