Round-Sharp Needle for Limb Spasms After a Stroke: Study Protocol for a Randomized Controlled Trial.

Abstract

Objective: Stroke can cause limb spasticity, and numerous clinical studies have demonstrated that acupuncture is an effective treatment for this condition. The round-sharp needle, a type of acupuncture needle, has been reported to shorten treatment durations and reduce the number of clinic visits compared to traditional filiform needles, the conventional acupuncture. However, clinical trial research on its efficacy remains limited. Therefore, this clinical trial is designed to investigate the short-term effects and safety of round-sharp needle therapy in treating post-stroke limb spasticity.

Methods and analysis: This research protocol outlines a randomized, single-blind, prospective, single-center pilot clinical trial to be conducted at Hubei Provincial Hospital of Traditional Chinese Medicine, scheduled to commence after completion of clinical trial registration. After the recruitment phase, eligible patients meeting the inclusion criteria will be randomly assigned to one of two groups: the round-sharp needle group (3 times per week) or the filiform needle group (5 times per week). The treatment will last for two weeks, with evaluation criteria including surface electromyography (sEMG), the Modified Ashworth Scale (MAS), the Fugl-Meyer Assessment (FMA), the Modified Barthel Index (MBI), and a safety assessment of acupuncture.

Conclusion: This clinical trial investigates the safety and efficacy of using round-sharp needles to treat post-stroke limb spasticity, with the results expected to provide further evidence for the future clinical application of this therapy.
