Dizziness
This month I would like to describe two conditions that provoke dizziness or unsteadiness and their treatment with physiotherapy. Everyone knows the sensation of unbalance when you had a glass of wine too much, but this article has nothing to do with our friend Rioja.
Our sense of balance is composed by 3 elements: The eyes: where is my body in space and how is it moving. The inner ear: detects gravity and back and forth motion. Sensory nerves: 1. pressure receptors in joints of the spine and lower extremities tell what part of your body is down. 2. muscle and joint sensory receptors (proprioception) tell what part of your body is moving or in what position it is.
3.The central nervous system (CNS) which processes all the information.
Dizziness appears when the CNS receives conflicting information. If the inner ear is involved we speak of Benign Paroxysmal Positional Vertigo (BPPV). There is an intense but brief sensation of spinning (vertigo) or unbalance after a change in head position such as lying down, turning in bed, looking up, or stooping. After about 30 seconds it ceases, when the head is still. This condition is due to dislodged crystals entering one of the semicircular balance canals of the inner ear. Epley “repositioning” treatment is usually curative. At home you can do Brandt-Daroff exercises to prevent it.
Cervical dizziness This term is reserved for cases where dizziness and unsteadiness are suspected to be of cervical origin and inadequate stimulation of neck receptors. If this valid information arrives at the CNS in a distorted way this can provoke a sensation of dizziness or loss of balance. Restoring normal function of the cervical spine, such as the treatment of short deep neck extensors, osteoarthritic joints or myofascial trigger points in the extensor muscles contribute to improve proprioception and resolve the dizziness. Dizziness and vertigo are conditions that can be related to serious pathology, so if your unbalance is different to the type mentioned in this article you should visit your ENT specialist or general physician.
