Overall stability index

1. Phase 1 angle-torque slope coefficient is associated with overall stability index in humans (r = 0.619).

   “a significant positive relationship was observed between OSI and the slope coefficient of phase 1 at baseline (r = 0.619; P = 0.042).”

1. Early rate of torque development is associated with overall stability index in humans (r = -0.601).

   “A significant relationship was also observed in the older (r = -0.601; p = 0.050) but not the younger (r = -0.132; p = 0.698) females between RTD50 and OSI.”
