Proprioception is the sensory response from muscles, tendons, and ligaments resulting from your actions and motions. Such as how fast one can move, how far one can stretch, how easy or hard executing a move while working out etc. These senses include:
- The senses of position and movement of our limbs and trunk
- The sense of effort.
- The sense of force.
- The sense of heaviness.
Proprioception involves receptors involved located in skin, muscles, and joints. Information about limb position and movement is not generated by individual receptors, but by populations of afferents.
Afferent signals generated during a movement are processed to code for endpoint position of a limb. The afferent input is referred to a central body map to determine the location of the limbs in space.
Experimental phantom limbs, produced by blocking peripheral nerves, have shown that motor areas in the brain are able to generate conscious sensations of limb displacement and movement in the absence of any sensory input.
In the normal limb tendon organs and possibly also muscle spindles contribute to the senses of force and heaviness.
Exercise can disturb proprioception, and this has implications for musculoskeletal injuries.
Proprioceptive senses, particularly of limb position and movement, deteriorate with age and are associated with an increased risk of falls in the elderly.
Most recently researches have offered more information available on proprioception giving a better understanding of the mechanisms underlying these senses as well as providing new insight into a range of clinical conditions
