Creepy effects of prolonged static flexion on sub-regional lumbar spine motion during manual lifting

With recent developments in the resolution with which spine skin-surface motion is tracked, the opportunity presented itself to calculate the effects of creep deformation on spine motion during manual lifting across smaller sub-regions of the lumbar spine. Study results demonstrated that lumbar spine range of motion during manual lifting was unaffected by soft tissue creep deformation; however, the repeated, intermittent lifting performed during the recovery portion of the experiment inhibited creep deformation recovery after 30 minutes.
