Abstract

Abstract: Objective To investigate the efficacy of a single session of extracorporeal shock wave therapy (ESWT) in alleviating triceps surae muscle tone and improving lower limb motor function in elderly patients with Parkinson’s disease. Methods From December 2024 to December 2025, 50 elderly patients with Parkinson’s disease and elevated triceps surae muscle tone at the First Affiliated Hospital of Nanjing Medical University were enrolled in this study. They were randomly allocated into a research group (n=25) and a control group (n=25). The research group received a single session of ESWT applied to the bilateral triceps surae muscles, while the control group received a single session of sham stimulation. Before the intervention and within 10 minutes after intervention, the Modified Ashworth Scale (MAS) for ankle dorsiflexion, the 10-Meter Walk Test (10MWT), and the Timed Up and Go test (TUGT) were assessed. Simultaneously, surface electromyography signals were recorded. The root mean square (RMS) value of the triceps surae at rest was used to evaluate changes in electrophysiological muscle activity. Results The MAS grade for ankle dorsiflexion, 10MWT speed, and TUGT time significantly improved in the research group than those in the control group (P＜0.001). Furthermore, the resting RMS of the medial gastrocnemius (P=0.026), lateral gastrocnemius (P=0.008), and soleus muscles (P=0.003) significantly reduced. Conclusions A single session of ESWT demonstrates an immediate effect in alleviating triceps surae muscle tone in elderly patients with Parkinson’s disease. It can effectively improve peri-ankle muscle tone and enhance functional mobility related to sit-to-stand and walking.
