Dizziness among patients with whiplash-associated disorder:: A randomized controlled trial

Objective: To investigate whether vestibular rehabilitation for patients with whiplash-associated disorder and dizziness had any effect on balance measures and self-perceived handicap. Design: Randomized, controlled trial. Subjects: Twenty-nine patients, 20 women and 9 men, age range 22-76 years. Methods: The patients were randomized to an intervention group or a control group. The intervention comprised vestibular rehabilitation. All patients were assessed at baseline, after 6 weeks and after 3 months with 4 different balance measures and the Dizziness Handicap Inventory. Results: After 6 weeks, the intervention group showed statistically significant improvements compared with the control group in the following measures: standing on one leg eyes open (p = 0.02), blindfolded tandem stance (p = 0.045), Dizziness Handicap Inventory total score (p = 0.047), Dizziness Handicap Inventory functional score (p = 0.005) and in Dizziness Handicap Inventory physical score (p = 0.033). After 3 months, the intervention group showed statistically significant improvements compared with the control group in the following measures: standing on one leg eyes open (p = 0.000), tandem stance (p = 0.033) and Dizziness Handicap Inventory physical score (p = 0.04). Conclusion: Vestibular rehabilitation for patients with whiplash-associated disorder can decrease self-perceived handicap and increase postural control.
