Lumbar position sense acuity during an electrical shock stressor

摘要: Background Optimal motor control of the spine depends on proprioceptive input as a prerequisite for co-ordination and stability spine. Muscle spindles are known to play an important role in proprioception. Animal experiments suggest that increase sympathetic outflow can depress muscle spindle sensitivity. As may be influenced by modulation, we hypothesized state high activity during mental stress would affect output from back muscles leading alterations proprioception position sense acuity. The aim was investigate effect stress, this study response electrical shock stressor, acuity rotational axis lumbar
