| Objective (Aim) | Comparison between CRP and TRV chair | Comparative study of the efficacy of the canalith repositioning procedure versus the vertigo treatment and rehabilitation chair | Repositioning chairs in benign paroxysmal positional vertigo: implications and clinical outcome | Reposition chair treatment improves subjective outcomes in refractory benign paroxysmal positional vertigo |
| Type of study | Prospective | Prospective | Prospective | Prospective |
| Type of BPPV | Lateral and posterior canalolithiasis + multi-canals | Unilateral posterior BPPV | Posterior canalolithiasis/ cupulolithiasis, Lateral cupulolithiasis + multi-canals | All types of refractory BPPV |
| Conclusion | TRV chair is more effective in treating multi-canals BPPV | Number of treatment sessions for successful repositioning is lower in TRV chair than in the CRP. | The EO and TRV chairs are highly valuable assets in diagnosis and management of BPPV. | Patients with refractory BPPV improved significantly by TRV chair. |
