To determine if spine stability would be affected by the competing demands of simultaneous challenged ventilation and supporting a hand-held load.Subjects were their own controls in a repeated measures design where a single task was repeated, once in a different condition, in a random order.Muscle stiffness influences spine stability. The same muscles that contribute to spine stability assist in challenged...
Quantifying the stability of the spinal column offers a perspective on the effectiveness of the motor control strategy to ensure a stable spine-and minimize the risk of injury from experiencing an unstable event. There are essentially three energy based methods of calculating a stability index for the lumbar spine. All three methods involve mathematical manipulation of an 18x18 Hessian matrix. The...
