Abstract

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.
In this pilot randomised controlled trial, 28 individuals with idiopathic PD (Hoehn & Yahr stage 2-3) 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®); the secondary was static balance (Tetrax® fall index). Group × time effects were analyzed using repeated-measures ANOVA (α = 0.05).
Groups were similar at baseline. At two weeks, only the sensor brace group showed significant improvement in Cranio-Horizontal Angle (~-2°, 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.
The sensor-based brace improved upper neck postüre in the short-term and was well tolerated. Longer training or combined strategies may yield greater functional gains.
