Mediolateral center-of-mass RMS acceleration

Thoracic kyphosis is associated with mediolateral center-of-mass RMS acceleration in humans (r = 0.492).

“greater thoracic kyphosis with greater pelvic ML COM RMS acceleration (r = 0.492).”

Posterior pelvic tilt is associated with mediolateral center-of-mass RMS acceleration in humans (r = -0.654 to -0.522).

“greater posterior pelvic tilt was associated with greater ML COM RMS acceleration of the head, pelvis, and whole body (r = -0.654 to -0.522)”

Older age is associated with mediolateral center-of-mass RMS acceleration in humans (Cohen's d = 0.83–1.96).

“Older adults had greater ML COM RMS acceleration in the head, thorax, pelvis, and whole body (all p ≤ 0.022; Cohen's d = 0.83–1.96)”
