The kinesthetic sense, the sense of position and movement of our limbs, has been the subject of speculation for more than 400 years. The present-day view is that it is signaled principally by muscle spindles, with a subsidiary role played by skin and joint receptors. The problem with muscle spindles as position sensors is that they are able to generate impulses in response to muscle length chan...

In the stationary hand, static joint-position sense originates from multimodal somatosensory input (e.g., joint, skin, and muscle). In the moving hand, however, it is uncertain how movement sense arises from these different submodalities of proprioceptors. In contrast to static-position sense, movement sense includes multiple parameters such as motion detection, direction, joint angle, and velo...

STUDY DESIGN A two-group experimental design with repeated measures on one factor was used. OBJECTIVES To investigate the role of paraspinal muscle spindles in lumbosacral position sense in individuals with and without low back pain. SUMMARY OF BACKGROUND DATA Proprioceptive deficits have been identified in patients with low back pain. The underlying mechanisms, however, are not well docume...

BACKGROUND Impaired cervical joint position sense and balance are associated with neck pain. Specific therapeutic exercise and manual therapy are effective for improving neck pain and functional ability but their effects on joint position sense and balance impairments remain uncertain. Changes in the joint position sense and balance may need to be addressed specifically. The primary objective i...
