Motion sickness is a common sensory–vestibular disorder, leading to symptoms such as nausea, dizziness, headache, fatigue, postural instability, and reduced functional performance. These symptoms arise due to sensory conflict between visual, vestibular, and proprioceptive inputs, particularly during travel and virtual reality exposure. Physiotherapy approaches such as Gaze Stability Exercises (GSE) and Vestibular Habituation Exercises (VHE) have shown promising outcomes in reducing motion sensitivity and improving balance. Neck Postural Stability Exercises (NPSE) further enhance cervical proprioception and neuromuscular control, contributing to better sensory integration.

This study aims to compare the effectiveness of Gaze Stability Exercises and Vestibular Habituation Exercises administered along with Neck Postural Stability Exercises in reducing symptoms of motion sickness.

An experimental randomized controlled trial design will be employed, comprising 32 participants aged 18–38 years with moderate level motion sickness. Participants will be randomly allocated into two groups based on predefined inclusion and exclusion criteria. Group A will receive Gaze Stability Exercises plus Neck Postural Stability Exercises, while Group B will receive Vestibular Habituation Exercises plus Neck Postural Stability Exercises. The intervention protocol will be administered four sessions per week for three weeks. Outcome measures including MSAQ, SSQ, and NDI will be recorded at baseline and post-intervention following controlled VR exposure. Statistical analysis will be conducted using appropriate methods to determine the significance of findings.

The study intends to propose a cost-effective, safe, non-pharmacological, and evidence-based physiotherapeutic approach for the management of motion sickness. Ethical considerations will be strictly followed, and written informed consent will be obtained from all participants prior to study initiation.
