Prospective study evaluates gait and posture changes in Parkinson's disease with wearable technology, suggesting stimulation shows superior efficacy.

This study aims to investigate the effects of subthalamic stimulation and levodopa on gait and posture in individuals with Parkinson's disease.
Prospective study using wearable sensor technology to measure gait and posture in 33 subjects with PD.
Evaluated conditions included pre-operative and post-operative states at 6 months after STN-DBS surgery, both OFF/ON medication and stimulation.
Standardized response mean (SRM) values were calculated to assess treatment responsiveness.
Significant improvements were seen in gait parameters such as speed, stride length, and cadence following STN-DBS.
Stimulation showed superior enhancement of gait speed and stride length compared to levodopa, as indicated by SRM.
Postural parameters displayed minimal change after STN-DBS, indicating a need for further research into this area.

Cani et al. (2024) studied this question.
