Proprioceptive system: Difference between revisions - VR & AR Wiki

Line 76:

The central nervous system receives input from several sources like the somatosensory system, the vestibular system, and the visual system. The somatosensory system is composed by several types of receptors, like mechanoreceptors, thermoreceptors, pain receptors, and proprioceptors. The integration of proprioceptive signals by the central nervous system is still not completely understood, despite several studies on the subject matter. The traditional views are changing and some propose that the sense of position and movement results from integrating multiple sources of proprioceptive information within the central nervous system, and not just from muscle spindles <ref name=”5”></ref>.

==Effect of exercise==

The effect of exercise in the sense of position remains controversial to explain, and further research is necessary. Some studies suggest a decline of the sense of velocity and position sense after an isometric contraction exercise protocol. Indeed, there is a common feeling of awkwardness and clumsiness after intense exercise that is not only muscle weakness, but also a lesser certainty about the placement of the fatigued limbs in the absence of vision <ref name=”2”></ref> <ref name=”5”></ref>.

There is also the suggestion that the effort that is required to maintain the position of a limb against the force of gravity is the element that provides the positional cue, although some studies contradict this sense of effort hypothesis. Moreover, data supports the view that muscle spindle would be responsible for the sense of movement, not being sensitive to exercise disruption <ref name=”5”></ref>.
