Vertigo is a feeling of dizziness and a sensation of being off balance. In athletes, vertigo is a common side effect of concussion. While vertigo often resolves itself over time, persistent symptoms may need medical intervention. If you are an athlete suffering from vertigo, sports chiropractic care may offer the best solution.
Balance is defined as your ability to maintain your body’s center of mass over its base of support when standing or moving. Balance is a key component in any sport, protecting your from falls and injury while on the playing field. Sports trauma can affect the systems responsible for achieving and maintaining balance, leading to vertigo.
Three systems interact to help you achieve and maintain balance: The proprioceptors located in your muscles and tendons; the vestibular system located in your inner ear; and your brain’s cerebellum.
Information about your body’s position in space is continually being sent to your brain from proprioceptors in your muscles and tendons. Proprioceptors are specialized receptors, located on nerve endings throughout your body, found in tendons, joint capsules, muscles, and in your inner ear, that provide feedback about your body’s position relative to gravity.
During physical activity, proprioceptors detect changes in muscle tension, body position and force production, helping your brain make adjustments to maintain equilibrium.
There are three types of proprioceptors:
The vestibular system provides feedback about spacial orientation, motion and equilibrium via sensory receptors in your inner ear. When combined with visual feedback, the vestibular system helps you make adjustments to maintain balance. Without visual input, balance becomes more difficult.
During sports, your vestibular system kicks into high gear, giving specific feedback about acceleration, deceleration, and vertical movement when jumping or bounding. Without vestibular feedback, you would be unable to perform as an athlete.
Dizziness originates deep within the inner ear, where three fluid-filled canals (utricles) and two sac-like structures (saccules) interact. Within the canals, hair-like structures connected to nerves respond to fluid flowing past, relaying information about body position and motion. Tiny stones in the saccules move the hairlike structures when the body is in motion.
When you take a hard fall or collide with another player, the stones can become dislodged from the saccules and move into the canals, creating an eddy that changes the fluid flow across the hairs, resulting in misinformation to the brain and causing vertigo.
When your proprioceptors and vestibular system respond to changes in equilibrium, that information is sorted in your brainstem at the top of your spinal column, and sent to your cerebellum, where balance, posture and movement are coordinated and regulated. When signals are confused, as is the case with vertigo, balance is disrupted as your brain struggles to resolve the conflicting information.
Imagine if you became dizzy every time you made a sudden move during play. This can occur after a concussion, setting you up for a serious injury. A sports chiropractor works with you to help restore balance and reestablish spacial awareness.
Benign paroxysmal positional vertigo (BPPV) is the most common type of concussion, related to brainstem trauma. You may feel dizzy when turning your head or changing body positions.
At NYDNR, a sports chiropractor can help you overcome BPPV through exercises designed to move the tiny stones of your vestibular system out of the canals and back into the saccules, thus restoring balance. We use a combination of exercises and spinal adjustments to eliminate vertig. We also use CAREN (computer assisted rehabilitation environment) to improve vestibular feedback and restore equilibrium.
