Methods: Thirty-eight individuals with Parkinson’s disease were included in this study and were divided into “PD–Neck Vibration” and “PD–Sham” groups. Vibration at 80 Hz was applied to the neck muscles for 10 minutes. All participants were assessed with the Retropulsion Scale, 3-Meter Backward Walking Test (3MBWT), limits of stability, postural sway, and subjective fear of falling. Measurements were performed in both groups before and after the intervention. Results: Significant improvements were observed in the intervention group in the Retropulsion Scale, 3MBWT, right way limits of stability, and postural sway on foam with eyes open (p<0.001, p<0.001, p=0.041, p=0.027). In between-group analysis, the pre–post differences in the Retropulsion Scale and the 3-Meter Backward Walking Test were significantly higher in the intervention group compared to the sham group (p<0.001). These findings indicate that the intervention is particularly effective on reactive and dynamic balance as well as functional mobility. Conclusion: The significant differences in retropulsion and 3-meter backward walking between the groups suggest that the intervention may particularly target posterior postural stability, balance, and functional mobility. This effect may be associated with the increased proprioceptive input and enhanced postural stability resulting from the “lengthening” illusion created by vibration on the muscle spindles.
