A Clinical Trial Protocol to Compare the Effect of Dry Needling and Acupoint Dry Needling on Wrist Flexor Spasticity after Stroke

Background: Stroke is the leading cause of disability in adults worldwide, with spasticity after stroke being one of the more common complications. Dry needling (DN) has been demonstrated to decrease spasticity in stroke patients, although its effects on improving function remain unclear. The purpose of this study protocol is to compare the short-term effects of DN versus acupoint DN on wrist flexor spasticity and upper extremity function in patients with stroke.Methods: A double-blind, randomized clinical trial will be conducted to include patients with stroke and upper extremity spasticity and functional disability. Twenty-four patients with stroke will be randomly assigned to either the DN or acupoint DN (DNap) group. These groups will receive three DN sessions during a one-week period of the wrist flexor muscles or at the LI4 & TE5 acupoints, respectively. The primary outcome measure is the Modified Modified Ashworth Scale (MMAS) of spasticity. The secondary outcomes are the Fugl-Meyer Assessment of motor function (FMA) and the goniometry to assess the active and passive range of motion of the wrist. Data will be collected at baseline, immediately after the end of three sessions DN, and at a one-week follow-up visit.Discussion: The results of this comparative study will help to determine the more effective method for reducing spasticity and improving motor function in patients with stroke.
