This study will be an evaluation of the efficacy and safety of acupuncture for cervical spondylotic radiculopathy. The main questions it aims to answer are 1. Does acupuncture improve the pain intensity among patients with cervical spondylotic radiculopathy? 2. Does acupuncture treat cervical spondylotic radiculopathy safely? Researchers will compare acupuncture to sham acupuncture to see if acupuncture could improve symptoms among patients with cervical spondylotic radiculopathy. Experimental and control groups will be treated with 6 weeks of acupuncture or sham-acupuncture respectively. Patients were followed up at 1 month, 3 months, 6 months after treatment to record outcome, any disease progression, adverse events, and so on.
