Tasapainoaisti, also known as the sense of balance, is the perception of the body's orientation and movement in space. It is a complex sensory system that involves the interplay of several components, primarily the vestibular system located in the inner ear, vision, and proprioception. Proprioception is the sense of the relative position of one's own parts of the body and strength of effort being employed in movement.

The vestibular system, consisting of the semicircular canals and otolith organs, is crucial for detecting head movements and gravitational forces. The semicircular canals are sensitive to rotational movements, while the otolith organs (utricle and saccule) detect linear acceleration and the pull of gravity. Information from the vestibular system is transmitted to the brain, where it is integrated with visual and proprioceptive input to create a coherent sense of balance.

Vision plays a significant role by providing information about the surrounding environment and helping to maintain stability. Proprioceptors, found in muscles, tendons, and joints, send signals to the brain about the position and movement of the body's limbs. This constant feedback loop allows for rapid adjustments to posture and movement, preventing falls and enabling coordinated actions.

Disruptions to the balance system can lead to symptoms such as dizziness, vertigo, unsteadiness, and nausea. These issues can arise from various causes, including inner ear infections, head injuries, certain medications, or age-related changes. Maintaining good balance is essential for performing everyday activities safely and efficiently, from walking and standing to participating in sports and other physical endeavors.
