Abstract:

Objective To investigate the current trend of non-drug therapy for gait abnormality of Parkinson's disease.

Methods The clinical trials about non-drug therapy for gait abnormality of Parkinson's disease were retrieved from the clinical trial registration platform ClinicalTrials.gov, from inception to October 25th, 2022. The records were screened by two researchers independently, and the registration time, registration count, sample sizes, interventions, primary outcome measurements and study design, etc., were summarized and analyzed, according to the PICOS principle.

Results A total of 218 eligible records were included. The registration count increased in recently years. Almost all of the trials (93.6%) were with a relatively small sample size less than 100, mainly 21 to 30 cases. The major intervention approach was the neuromodulation technique, however, virtual reality and robot-assisted gait training were coming to use in recent years. The primary outcome measurements were the clinical scales, the questionnaires and the exercise examinations. Randomized parallel controlled trials were the most (111, 50.9%).

Conclusion The number of non-drug therapy for gait abnormality of Parkinson's disease increased year by year. The new technologies such as virtual reality and robot-assisted gait training may be used more in the future.
