Proprioception
Proprioception is the body's ability to sense its position and movement within space, often referred to as a "sixth sense." It enables individuals to understand where their limbs are located, both when stationary and in motion, even with eyes closed. This sensory awareness stems from specialized receptors called proprioceptors, which are found in muscles, joints, tendons, and the inner ear, helping to relay information about body positioning to the brain. Proprioception operates on a subconscious level, facilitating quick muscle responses for coordinated movement, while also engaging with conscious awareness, particularly during activities that require precise body control, such as sports or dance.
The interplay between proprioception and kinesthesia—awareness of body movement—is crucial for effective motion and response. Proprioception plays a vital role in everyday life, influencing how individuals navigate their environment and interact socially. Challenges in proprioceptive processing can lead to difficulties in coordination and balance, often requiring rehabilitation to restore proper function. Overall, proprioception is an essential component of physical health and performance, underlying both routine tasks and complex athletic activities.

Proprioception
The sense of our body's positioning is known as proprioception. This may refer to the body's position in a stationary mode, knowing and feeling where the limbs are. It also refers to understanding our body in movement. Without this sensory knowledge, a person would not be able to determine the orientation of the body either in stillness or when moving. Proprioception comes into play also with the eyes closed, as even then there is a sense of where and how the body and its parts are located in relation to the self and to the broader spatial environment. Proprioception may be called a "sixth sense," since it is the ability to sense where the body is positioned.
Background
Proprioception. Proprioception is the capacity an individual possesses to sense the body's position and orientation. Where each body part is, where the body parts are when standing, walking, running, or dancing all form components of the proprioceptive sense. The three main components of proprioception include a sense of the joint's position, a sense of balance, and of body awareness.
Proprioceptors. Proprioceptors are also called stretch receptors. These receptors are found in joints, muscles, ligaments and tendons, and the inner ear. The muscle spindles of the arms and legs, and the Golgi tendon organ (found at the meeting point between muscle and tendon) are examples of proprioceptors. Their function is to send the brain messages about the body's position. The inner ear is a proprioceptor helping the orientation and balance of the body.
Proprioceptive System. The proprioceptive system is made up of a system of proprioceptors (receptor nerves). Somewhat like inner antennae picking up the slightest changes, as soon as the proprioceptors sense these alterations, the impulse to the brain is activated. The brain receives the information and a system is set up whereby the body is now "instructed" to do or move in a certain way. The muscles react to the instruction almost as a reflex, so fast is the coding that takes place.
Imagine having eyes closed and being instructed to touch a part of the body such as the lips or nose. The ability to do so, knowing where to place the hand or fingertip is a result of the sensory mode of proprioception. This applies likewise to moving to a designated spot or performing an action in this manner, first with eyes open and then with closed eyes. Being able to move the hands, arms, or legs in space without actually looking at them and knowing where they are relates to proprioception. Being able to sense the direction even without being able to see it, is related to this sensory perception.
Overview
Proprioception works on a subconscious level. The internal proprioceptors signal the brain as to what type of delicate or larger movements are required. The muscles contract or relax to facilitate the body's movement per the required task at hand. On another level, proprioception acts in conjunction with a conscious level of bodily perception and action. Through mental awareness and physically adjusting the body according to the situation or moving toward or away, the interplay between perception and decision occurs.
Proprioception and Kinesthesia. Proprioception and kinesthesia are terms that are often used interchangeably; however they possess certain important differences. The predominant way in which the two are not the same is the subconscious aspect of proprioception versus the conscious awareness associated with kinesthesia. The interaction between proprioception and kinesthetic awareness is an important one, especially when it comes to movement or sport activities.
Proprioception and Daily Life. Proprioception is an essential tool in daily life. Understanding the body and its spatial relationships and appropriately perceiving these relationships as a broader whole particularly pertaining to interactions is a necessary personal and social skill.
Proprioception Sensory Processing Challenges. Sensory processing challenges may be experienced by a child or adult, indicating a proprioceptive dysfunction or disorder. According to the theory of sensory integration, proprioceptive sense tells us about movement and body position (sensory-processing-disorder.com). When someone is unable to receive or interpret these internal bodily messages, this may be referred to as a proprioceptive dysfunction or disorder. This may manifest in a person appearing to be clumsy or uncoordinated. In addition, this may be coupled with sensory-seeking behavior as well as having difficulties grading movement, misjudging length or pressure. A further emotional sense of insecurity may be experienced by the inability to hold the body in a stable fashion.
Proprioception, Balance, Exercise, and Sport. Proprioception is inextricably connected to sporting activities. Eyeing the ball, being able to run with speed, performing an action without needing to look at the body part are all connected to proprioception and essential to exercise and sport. The body's sense of and ability to balance are crucial to movement, from dance to lifting weights.
Proprioception, Injury, and Rehabilitation. When someone is injured and the nerve fiber is damaged, this can affect proprioception in that area. This might manifest as the brain not receiving the information due to the proprioceptor no longer functioning or receiving an incorrect message. Rehabilitation is necessary to restore function of the muscle, joint, or ligament injured and to retrain the affected area to restore the sense. Balance is also an essential part of the rehabilitation process toward regaining proprioception, as well as re-establishing kinesthetic awareness.
Proprioceptive Medicine. Proprioceptive medicine is a system of muscle testing utilized in the fields of chiropractics and osteopathy. The testing is designed to identify and diagnose aspects of the nervous system and the state of sensory input and relation to muscle vulnerability or strength. The goal is to reach optimum muscle tone and health.
