Aging, balance, and proprioception
Balance is inevitably affected by aging. As we age, there’s a decrease in the functioning of several systems that are closely related: the visual system, the vestibular system in the inner ear, as well as the proprioceptive system.
Proprioception is intimately linked to balance. It is a function, conscious and unconscious, by which we perceive the different parts of our body in space, allowing us to keep our balance even when we have our eyes closed or move in the dark. Muscles, bones, tendons and joint components play an essential role in proprioception by sending signals to our nervous system, allowing us to coordinate our movements.
In addition to aging, other factors can affect proprioception and, with it, balance:
- Injuries affecting muscles and different parts of the joints (sprains, torn ligaments, tendonitis, etc.);
- Diseases that affect joint health (osteoarthritis, inflammatory arthritis, etc.);
- Sedentary lifestyle caused by a lack of physical activity.
