Proprioception: Peripheral Inputs and Perceptual Interactions
- 796 Downloads
Much emphasis has been placed on the specific role of specific inputs from muscle, joint and cutaneous afferents in the detection of movement. However, particularly for the hand, multiple inputs from the moving part are likely to be important. This chapter reviews some recent studies which examine the co-operative interaction between the various proprioceptive channels. Proprioceptive control of movement must also take account of the length of the various limb segments, a variable which is independent of muscle lengths and joint angles. Evidence is presented that body image can be affected by the tonic discharge of non-muscle receptors.
