简要总结
This study compares the effectiveness of Gaze Stabilization Exercises and Optokinetic Training in improving dizziness, balance, and confidence in individuals with peripheral vestibular disorders.
详细描述
Peripheral vestibular disorders (PVD) commonly cause dizziness, postural instability, and decreased balance confidence, which increase the risk of falls and limit participation in daily activities. Vestibular rehabilitation is widely used to manage these symptoms. Among rehabilitation approaches, Gaze Stabilization Exercises (GSE) aim to improve vestibulo-ocular reflex function, while Optokinetic Training (OKT) promotes symptom habituation through visual motion stimulation. However, the comparative effectiveness of these two interventions remains unclear.
This study aims to compare the effects of GSE and OKT on dizziness severity, postural stability, and balance confidence in individuals with peripheral vestibular disorders. Participants will undergo intervention sessions three times per week for six weeks. Outcome measures will be assessed at baseline, mid-intervention (week 3), and post-intervention (week 6).
Primary and secondary outcomes will include the Dizziness Handicap Inventory (DHI), Dynamic Gait Index (DGI), and the Activities-specific Balance Confidence (ABC) Scale. Data will be analyzed using SPSS statistical software. It is hypothesized that both interventions will improve dizziness, balance, and confidence, though differences in effectiveness may exist between the two approaches.
The findings of this study are expected to contribute to evidence-based vestibular rehabilitation by identifying effective intervention strategies. The results may help clinicians design personalized rehabilitation programs aimed at reducing fall risk, improving functional mobility, and enhancing quality of life in individuals with peripheral vestibular disorders.

研究组 & 干预措施
Gaze Stabilization Exercises
Purpose:
Enhance gaze stability, postural control, and confidence in functional activities.
Description:
Week 1: Sitting, VOR x1 horizontal, fixate on near target - start gaze stability.
Week 2: Sitting, VOR x1 vertical, near/far target - increase head speed. Week 3: Standing, VOR x1 horizontal, fixate on target - improve upright balance.
Week 4: Standing, VOR x1 with busy background - challenge visual-vestibular interaction.
Week 5: Standing, VOR x2 horizontal/vertical - advanced gaze stabilization. Week 6: Standing, VOR x2 with busy background - integrate dynamic visual input.
干预措施: Gaze stabilization exercises (Procedure)
Optokinetic Training
Purpose:
Reduce visually induced dizziness, enhance balance, and improve confidence in daily activities.
Description:
Week 1: Horizontal stripes Week 2: Vertical motion Week 3: Real-world videos Week 4: Crowded/busy scenes Week 5: Moving environment + light movement Week 6: Provocative videos (spirals/crowded)
干预措施: Optokinetic training (Procedure)
