Line 68:

The central nervous system distinguishes between muscle spindle impulses generated by muscle stretch and by fusimotor activity, which may further indicate the prominent role of these receptors in kinaesthesia <ref name=”5”></ref>.

==The sense of effort==

Traditionally, the sense of effort, force, and heaviness have been regarded as to be generated by signals of central origin associated with motor commands. The senses of effort, force, and heaviness are distinct, has proprioceptive sensations, since they are always associated with motor commands. Kinaesthetic sensations can arise in passive limbs. Recent developments have given the centrally generated sense of effort a greater contribution to position sense. Fortier and Basset (2012) mention that the current hypothesis is that when “spindles are activated through the fusimotor system, they no longer contribute to position sense and the effort signal generated by the motor command provides the additional positional information”, and that “future experiments should concentrate on identifying the central sites of origin of the effort sensation, determining the effect of sense of effort on position sense, and assessing the interaction between peripheral and central systems.” <ref name=”2”></ref> <ref name=”5”></ref> <ref name=”7”></ref>
