proprioceptivas

Proprioceptivas refers to the proprioceptive system, which provides the central nervous system with information about the position and movement of the body. This sensory system allows a person to know where limbs are without looking and to monitor the effort and direction of movements. Proprioceptivas is closely linked to proprioception, kinesthesia and body schema.

The sensory input comes from specialized receptors called proprioceptors. The main types are the muscle spindles, which detect changes in muscle length and velocity; the Golgi tendon organs, which sense muscle tension; and various joint and cutaneous receptors that monitor joint position and movement. The primary afferent fibers carry signals to the spinal cord, where pathways diverge to reach the brain. Conscious proprioception primarily travels via the dorsal column-medial lemniscus pathway to the thalamus and cortex, while unconscious proprioception reaches the cerebellum through spinocerebellar tracts, contributing to automatic coordination of movement.

Functionally, proprioceptivas supports posture, balance, and coordinated motor control. It informs motor commands about limb position, allows precise adjustments during movement, and contributes to motor learning by updating internal models of the body in space. Proprioceptive information is essential for activities ranging from standing still to complex athletic maneuvers and fine motor tasks.

Clinical relevance includes proprioceptive deficits resulting from neuropathies, stroke, spinal cord injury, or degenerative conditions. Such deficits can impair balance, coordination and gait. Assessment commonly involves tests of joint position sense and kinesthetic awareness, such as limb repositioning tasks or balance evaluations, sometimes complemented by Romberg or cerebellar tests. Rehabilitation often focuses on restoring proprioceptive feedback through targeted sensorimotor training.
