May 4, 2026 updated by: Yaren Çelik, Gaziosmanpasa Research and Education Hospital

Contribution of an Ai Chi-Based Rehabilitation Program in Patients With Peripheral Unilateral Vestibular Dysfunction: A Randomized Prospective Single-Blind Study

This study aims to evaluate the effects of an Ai Chi-based rehabilitation program on balance, dizziness severity, and quality of life in patients with unilateral peripheral vestibular hypofunction. Participants will be randomly assigned to either a control group receiving standard home-based vestibular rehabilitation exercises or an intervention group receiving additional Ai Chi sessions. The intervention will be conducted over a 4-week period with a total of 10 sessions under the supervision of a certified therapist.

Detailed Description

Unilateral peripheral vestibular hypofunction is a clinical condition characterized by reduced vestibular function due to inner ear or vestibular nerve pathology. It presents with symptoms such as dizziness, imbalance, visual instability, and impaired postural control, significantly affecting functional independence and quality of life. Diagnosis is typically established by the otorhinolaryngology clinic and supported by vestibular function tests such as videonystagmography (VNG) and video head impulse testing (vHIT).

Vestibular rehabilitation is an evidence-based therapeutic approach aimed at promoting central compensation through mechanisms of adaptation, substitution, and habituation. These mechanisms contribute to the improvement of vestibulo-ocular reflex function, postural stability, and overall functional performance.

Ai Chi is an aquatic exercise program derived from Tai Chi and Qi Gong principles, consisting of slow, continuous, and controlled movements coordinated with breathing. The aquatic environment provides unique therapeutic properties such as buoyancy, hydrostatic pressure, and viscosity, allowing safe movement, reducing fall risk, and enhancing proprioceptive and sensory input. These features may support multisensory integration and facilitate central compensation in patients with vestibular dysfunction.

Although aquatic therapy has been increasingly used in rehabilitation, there is limited evidence regarding the effectiveness of Ai Chi specifically in patients with unilateral peripheral vestibular hypofunction. To the best of our knowledge, no randomized controlled study has specifically evaluated the effects of Ai Chi in this patient population.

In this randomized controlled study, participants will be allocated into two groups. Both groups will receive a standardized home-based vestibular rehabilitation program. In addition, the intervention group will participate in supervised Ai Chi sessions conducted in an aquatic environment over a 4-week period, consisting of a total of 10 sessions. All sessions will be delivered by a certified therapist, and adherence will be monitored using exercise logs.

Assessments will be performed at baseline, immediately after the intervention, and during the follow-up period by a blinded evaluator. The findings of this study are expected to contribute to the development of alternative rehabilitation strategies and provide additional evidence for the management of patients with vestibular disorders.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Ai Chi Group
Participants in this group will receive an Ai Chi-based aquatic exercise program in addition to standard home-based vestibular rehabilitation exercises. The Ai Chi program will be applied over 4 weeks with a total of 10 sessions under the supervision of a certified therapist.
Behavioral: Ai Chi-based exercise program
Ai Chi-based exercise program is a structured aquatic therapy approach consisting of slow, continuous, and controlled movements combined with breathing techniques. The program will be conducted in a pool environment over 4 weeks, with a total of 10 sessions delivered as group sessions under the supervision of a certified therapist. The exercises are designed to enhance balance, postural control, proprioceptive input, and multisensory integration, thereby supporting central compensation in patients with vestibular dysfunction.
Behavioral: Home-Based Vestibular Rehabilitation
Participants will receive a structured home-based vestibular rehabilitation program including gaze stabilization, head movement, balance, and postural control exercises. The program aims to promote vestibulo-ocular reflex adaptation, improve postural stability, and reduce dizziness-related symptoms. Participants will be instructed to perform the exercises regularly, and adherence will be monitored using exercise logs.
Active Comparator: Control Group
Participants in this group will receive standard home-based vestibular rehabilitation exercises without additional Ai Chi intervention.
Behavioral: Home-Based Vestibular Rehabilitation
Participants will receive a structured home-based vestibular rehabilitation program including gaze stabilization, head movement, balance, and postural control exercises. The program aims to promote vestibulo-ocular reflex adaptation, improve postural stability, and reduce dizziness-related symptoms. Participants will be instructed to perform the exercises regularly, and adherence will be monitored using exercise logs.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in balance performance assessed by Berg Balance Scale
Time Frame: Baseline, immediately after the 4-week intervention, and 2 months after the end of treatment
Change in balance performance will be assessed using the Berg Balance Scale (BBS). The BBS consists of 14 items scored from 0 to 4, with a total score ranging from 0 to 56. Higher scores indicate better balance performance. balance performance will be assessed using the Berg Balance Scale in participants receiving Ai Chi-based exercise program in addition to home-based vestibular rehabilitation, compared with participants receiving home-based vestibular rehabilitation alone.
Baseline, immediately after the 4-week intervention, and 2 months after the end of treatment

Secondary Outcome Measures
