Abstract
INTRODUCTION: Stiff neck is a condition mainly characterised by persistent pain and limited neck movement, which can substantially impact patients' daily lives during acute episodes. Accordingly, rapid pain relief and restoration of normal activities are the main needs of patients during doctor visits. This study aims to assess the immediate efficacy of acupuncture combined with active exercises in rapidly relieving pain and improving movement disorders within 10 min in patients with acute stiff neck (ASN). METHODS AND ANALYSIS: This randomised controlled clinical trial is being conducted at a single centre in China. 120 participants diagnosed with ASN will randomly be assigned in a 1:1:1 ratio to one of three groups: the acupuncture combined with active exercise group (group A), sham acupuncture combined with active exercise group (group B) and active exercise only group (group C). Each participant will undergo a single 10 min session. The primary outcome is the effective rate at 10 min of treatment. Secondary outcomes include the effective rate at other time points (0-1, 2, 4, 6 and 8 min), Visual Analogue Scale score and cervical range of motion. The intention-to-treat analysis will include all randomised participants. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of the Second Affiliated Hospital of Yunnan University of Chinese Medicine (2022-009). Written informed consent will be obtained from all participants before randomisation. The findings of this study will be disseminated through publication in a peer-reviewed journal and presentation at conferences. TRIAL REGISTRATION NUMBER: ChiCTR2200066997.
