One Leg Standing Test: A Quantification of the Neuromuscular System for Spine Research and Practice

Recurrent low back pain (LBP) is a common musculoskeletal problem, and there is a 24% to 87% recurrence rate within one year [1,2]. Those who have recovered from an episode of LBP demonstrated altered paraspinal muscle spindle afference and central processing of this sensory input for balance performance [3-5], altered proprioceptive postural control that might be caused by anticipation of postural instability, and less refined positional sense [6-8]. However, there is a lack of data to quantify altered kinematic and kinetic changes from postural coordination and balance performance in subjects with neuromuscular dysfunction.
