简要总结
Many people who use computers for long hours experience "cybersickness" (dizziness, nausea, blurred vision) because their eyes see movement on the screen but their body feels still. This study aims to see which type of eye and head exercises works best to fix this. We will compare Gaze Stabilization Exercises (head movements) against Oculomotor Exercises (eye movements). Forty-six computer users will perform these exercises for 4 weeks. We will measure their dizziness, vision, and quality of life before, during, and after the treatment.
详细描述
This is a single-blinded, randomized clinical trial. Participants (n=46) will be recruited from The University of Faisalabad. Inclusion criteria include screen time >6 hours/day, computer usage for at least 10 years, and a Simulator Sickness Questionnaire (SSQ) score between 20 and 40.
Group A (Intervention): Gaze Stabilization Exercises. Week 1: View X1 exercises. Week 2: View X2 exercises. Week 3: Gaze shift exercises. Week 4: Imaginary Target exercises. (3 sessions/week, 1 minute per exercise, 3 times each).
Group B (Active Comparator): Oculomotor Exercises. Week 1: Range exercises. Week 2: Saccadic exercises. Week 3: Pursuit exercises. Week 4: Vergence exercises. (3 sessions/week, 1 minute per exercise, 3 times each).
Outcomes: The primary outcome is the change in Dynamic Visual Acuity (LogMAR scale) and Cybersickness (SSQ score). The secondary outcome is Quality of Life (SF-36 questionnaire). Measurements will be taken at baseline, Week 2, and Week 4. Data will be analyzed using SPSS version 20.

盲法说明
The assessor measuring DVA, SSQ, and SF-36 will not know group allocation. Participants and exercise providers cannot be blinded due to the nature of the exercises.

研究组 & 干预措施
Oculomotor Exercises Group
Participants in this arm will receive Oculomotor Exercises for 4 weeks, 3 sessions per week. The protocol includes Range, Saccadic, Pursuit, and Vergence exercises. Each exercise is performed for 1 minute, repeated 3 times per session. Exercises target isolated eye movements without head motion to improve oculomotor control and reduce visual strain.
干预措施: Oculomotor Exercises (Behavioral)
Gaze Stabilization Exercises
Participants in this arm will receive Gaze Stabilization Exercises (GSE) for 4 weeks, 3 sessions per week. The protocol includes View X1, View X2, Gaze Shift, and Imaginary Target exercises. Each exercise is performed for 1 minute, repeated 3 times per session. Exercises target the vestibulo-ocular reflex (VOR) by coordinating head and eye movements to reduce sensory conflict.
