Whiplash associated syndrome is one of the neck disorders that is accompanied by several chronic symptoms. Balancing problems arising from common disorders and dizziness are considered as manifestations that are time-consuming to evaluate and treat. The present study aims to investigate the effect of vestibular-balance rehabilitation using a test that can be used for differential diagnosis of these lesions by comparing dizziness handicap inventory (DHI) and Smooth Pursuit Neck Torsion (SPNT) scores.This was an analytical cross-sectional study with a two-stage design. Forty patients with whiplash-associated disorders were randomly divided into control and intervention groups. SPNT test and DHI evaluation were performed for both groups. For twenty people selected randomly in the intervention group, vestibular-balance rehabilitation was performed during 12 sessions. Finally, the SPNT and DHI tests were performed again to examine and compare the results.The results of this study showed that there was a statistically significant difference between the scores of smooth pursuit neck torsion gain in the SPNT test, the total score of DHI, the functional components of this questionnaire between the control and intervention groups after the implementation of the rehabilitation, and the differences in the physical, functional, and emotional components of the questionnaires of the control and intervention groups after rehabilitation exercises.Vestibular-balance rehabilitation exercises can be an effective treatment for dizziness and improving the quality of life of a person suffering from whiplash-associated disorder, followed by the reduction in dizziness caused by disability.
