neuro anatomy of dizziness 10.1 vestibular rehab: intro to maintain postural orientation somatic system: proprioceptive input via golgi tendons and jnt receptors vision: clarity if sight, field of vision, visual processing centers in brain cerebellum, muscles & jnts: gives us info & react to info to allow us to maintain stability vestibular system & cervico-ocular reflex: vital info for orientation dizziness: differential dx questions to ask is the issue arising from the eyes? brain? ears? heart? metabolic system? msk system? PTs only treat, cervical jnt issues, vestib system or proprioceptive msk system everything else requires interdisciplinary approach to dx dizziness. what is it? dizziness affects 20-30% of ppl PT: understand what pt may mean by dizziness bc its vague pt could mean room is spinning, lightheadedness or blurry vision>>loss of balance or feeling weak in the legs dizziness encompasses various sensations of alerted body orientation or position 1st goal: question pt to determine what they mean exactly by complaining of dizziness dizziness. the prob ask subjective questions 6 categories: 1. vertigo of central 2. vertigo of peripheral pathology 3. 4. dizziness due to presyncope cardiovascular or other etiology, 5. disequilibrium, 6. nonspecific or multifactorial vertigo: abnormal sensation of motion -can occur in absence of motion or when a motion is sensed inaccurately ex: room spinning : vertigo of peripheral cause of inner ear central pathologY: caused by damage to CNS peripheral: damage to structures of inner ear or CN determine if we can tx or refer out disequilibrium: sensation of impending fall or need to obtain external assistance for proper locomotion ^ sometimes described as tilt of floor or sense of floating -sensation originated from inner ear, other motion sensors or CNS presyncope: lightheadedness, feeling like youre gonna blackout; consciousness preserved most common cause of syncope or presyncope: sudden drop in BP symptoms: lightheadedness, general weakness, warmth, diaphoresis, nausea, palpitations, blurry vision presyncope includes cardiac and non cardiac etiologies role to PT determine type of dizziness/vertigo refer, tx or independent dx PTs have ability to assess for & tx BPPV, cervicogenic dizziness, or msk impairment summary dizziness is a vague complaint with vestibular issues being the most prevalent cause key subjective questions will facilitate differential diagnosis and direct assessment
