OBJECTIVE: Postural deformities such as camptocormia affect over 30% of Parkinson's disease (PD) patients, impairing balance, gait, and quality of life. This study evaluated a vibratory-feedback posture brace versus conventional exercises in PD. DESIGN: In this pilot randomised controlled trial, 28 individuals with idiopathic PD (Hoehn and Yahr stage 2 to 3) and stooped posture were assigned to either a 6-week daily exercise programme (Posture Exercise Group, n = 13) or a wearable brace (Sensor Brace Group, n = 15), worn around eight hours per day. The brace delivered vibration cues when forward flexion exceeded a set threshold. Primary outcomes were Craniovertebral and Cranio-Horizontal Angle (APECS R); the secondary was static balance (Tetrax R fall index). Group x time effects were analyzed using repeated-measures ANOVA (alpha 0.05). RESULTS: Groups were similar at baseline. At two weeks, only the sensor brace group showed significant improvement in Cranio-Horizontal Angle (approximately-2degree, p = 0.046), indicating a short-term, localized benefit. By 6 weeks, both groups had modest head posture improvements. Trunk Sagittal Angle and fall index showed no significant change. CONCLUSION: The sensor-based brace improved upper neck posture in the short-term and was well tolerated. Longer training or combined strategies may yield greater functional gains.
