The vestibular system:
- controls balance
- controls posture
- regulates locomotion and other movements
- provides conscious awareness of orientation in space
- provides conscious awareness of visual fixation in motion
Balance can be impaired by:
- altered gravity
- exposure to unusual motion
When balance is impaired, normal movement is affected, as well as motivation, concentration, and memory.
An estimated 2 million adults suffer from chronic dizziness or difficulty with balance. It particularly affects people aged 65 or older.
