Three Systems Causing Your Dizziness Post-concussion dizziness affects 50-80% of patients and involves three disrupted systems working together: your vestibular system (inner ear), cervical proprioception (neck position sensors), and autonomic nervous system (blood pressure regulation). Understanding which system drives your dizziness guides effective treatment (Mucha et al., 2014). Your brain integrates information from all three systems to maintain spatial orientation. When one system sends inaccurate data, you feel off-balance. When two or three systems malfunction simultaneously, as happens in concussion, the dizziness becomes debilitating. The good news: each system responds to targeted rehabilitation. Identifying your primary dizziness driver accelerates recovery. Vestibular System Dysfunction Benign paroxysmal positional vertigo (BPPV) affects 10-25% of concussion patients. Calcium crystals in your inner ear (otoconia) dislodge from the utricle into the semicircular canals during impact. These displaced crystals create false rotation signals when you change head position, producing brief intense spinning (vertigo) lasting 15-60 seconds. BPPV responds to repositioning maneuvers (Epley or Semont) performed by a trained provider. One to three sessions resolve symptoms in 80-90% of cases. This is the most treatable cause of post-concussion dizziness. Vestibular hypofunction occurs when the inner ear or vestibular nerve sustains direct damage from concussion forces. Your affected ear sends weaker signals than the healthy side, creating asymmetry your brain interprets as motion. This produces constant unsteadiness rather than positional spinning. Vestibular rehabilitation therapy (VRT) retrains your brain to compensate for asymmetric input. Gaze stabilization exercises, balance training, and habituation drills systematically improve vestibular function over 4-8 weeks. Cervicogenic Dizziness Your cervical spine contains the highest density of proprioceptive sensors in your body. These sensors continuously report head position to your brain, providing essential data for balance and spatial orientation. Concussion forces damage these sensors through cervical joint strain, muscle injury, and ligament sprain. Cervicogenic dizziness produces a vague unsteadiness, lightheadedness, and feeling of spatial disorientation. It worsens with sustained head positions and improves with cervical movement. Turning your head, looking up, or maintaining a fixed gaze for extended periods typically provokes symptoms. This is the most commonly missed cause of persistent post-concussion dizziness. Patients receive vestibular treatment without improvement because the cervical proprioceptive component goes unaddressed. Address cervicogenic dizziness with targeted neck mobility exercises that restore proprioceptive accuracy. Neck Exercises for Dizziness Reduction Cervical mobility work retrains proprioceptive pathways and reduces cervicogenic dizziness: JME 1 Slow cervical rotation provides high-quality proprioceptive input recalibrating position sense. JME 5 Controlled rotation with body awareness retrains cervical-vestibular coordination. JME 14 Chin tuck addresses suboccipital dysfunction affecting upper cervical proprioception. JME 22 Wide rotation challenges proprioceptive accuracy through increased range of movement. Supporting Exercises for Balance Recovery JME 3 Lateral flexion addresses cervical segments providing lateral balance information. JME 38 Shoulder mobility reduces upper body tension patterns affecting cervical proprioception. JME 150 Thoracic rotation supports spinal mobility reducing compensatory cervical loading. JME 166 Shoulder elevation releases tension patterns contributing to cervical proprioceptive distortion. Autonomic Dizziness Concussion frequently disrupts autonomic nervous system regulation of blood pressure and heart rate. When you stand from sitting, your body should increase heart rate and constrict blood vessels within seconds to maintain cerebral blood flow. Post-concussion autonomic dysfunction delays this response, allowing a temporary drop in brain blood flow that causes lightheadedness. Autonomic dizziness worsens with positional changes (lying to sitting, sitting to standing), prolonged standing, hot environments, dehydration, and after meals. It differs from vestibular dizziness because it improves when you sit or lie down. Management includes hydration (2-3 liters daily), graduated exercise to retrain autonomic responsiveness, compression garments for prolonged standing, and slow positional transitions. Most patients recover normal autonomic function within 2-4 weeks with active management. How to Identify Your Dizziness Type Spinning vertigo triggered by position changes (rolling in bed, looking up, bending over) = likely BPPV. Brief episodes (under 60 seconds) with specific head positions. Vague unsteadiness worsened by head movements and neck positions = likely cervicogenic. Improves with gentle neck movement, worsens with sustained positions. Lightheadedness when standing or with prolonged upright posture = likely autonomic. Improves immediately when sitting or lying down. Constant unsteadiness with motion sensitivity = likely vestibular hypofunction. Worsens in visually busy environments and with head movement. Many patients have multiple dizziness types simultaneously. Effective treatment addresses all contributing mechanisms rather than focusing on one. Start dizziness-reducing mobility work with simplmobility's programs that address the cervical component of post-concussion balance problems. FAQ How long does dizziness last after concussion? 50-60% of patients recover within 2 weeks. 80-90% recover within 2-3 months. BPPV resolves fastest (often with a single treatment session). Cervicogenic and vestibular dizziness typically take 4-8 weeks of targeted rehabilitation. Persistent dizziness beyond 3 months requires comprehensive evaluation. Does lying down help concussion dizziness? Lying down helps autonomic dizziness (lightheadedness from blood pressure drops) but not vestibular or cervicogenic types. BPPV often worsens when lying down and rolling over. If lying down consistently helps, your dizziness likely has an autonomic component requiring hydration and graduated exercise. Should I avoid movement when dizzy after concussion? Gentle controlled movement helps more than avoidance. Movement provides the sensory input your vestibular and proprioceptive systems need to recalibrate. Avoid rapid, unpredictable movements, but maintain slow, controlled head and neck movements multiple times daily. When should I see a specialist for post-concussion dizziness? If dizziness doesn't improve after 2-3 weeks, prevents return to normal activities, involves true spinning vertigo, or causes falls or near-falls. A vestibular physical therapist identifies the specific dizziness mechanism and provides targeted treatment. References Mucha, A., et al. (2014).
