Brief Summary
Cervical spondylotic radiculopathy (CSR) is one of the most common manifestations of cervical spondylosis and is characterized by neck pain radiating to the upper extremities, sensory disturbances, restricted cervical range of motion, and functional disability. Conservative treatment is recommended as the first-line management for most patients, and electroacupuncture is widely used in Traditional Medicine to relieve pain and improve function. Cervical Huatuo Jiaji (EX-B2) acupuncture points are anatomically located adjacent to the cervical spinal nerve roots and may provide more targeted therapeutic effects than conventional meridian acupuncture points. Pulsed electromagnetic field (PEMF) therapy has also been used as an adjunctive physical modality to reduce pain and facilitate functional recovery. This randomized controlled trial aims to evaluate whether high-frequency electroacupuncture at cervical Huatuo Jiaji (EX-B2) points combined with PEMF therapy provides greater improvement in pain intensity, cervical function, and safety outcomes than conventional high-frequency electroacupuncture combined with PEMF therapy in patients with cervical spondylotic radiculopathy caused by cervical spondylosis. The primary outcome is pain intensity measured using the Visual Analog Scale (VAS). Secondary outcomes include cervical range of motion, Neck Disability Index (NDI), and treatment-related adverse events. Clinical outcomes will be assessed at baseline, after one week of treatment, and at the end of the two-week treatment period.

Outcome Measures
Primary Outcomes (1)
Change in neck pain intensity measured by the Visual Analog Scale (VAS)
Neck pain intensity will be assessed using a 100-mm Visual Analog Scale (VAS). Participants indicate their pain intensity by marking a point on a horizontal line anchored by "no pain" at 0 mm and "worst imaginable pain" at 100 mm. The score is determined by measuring the distance in millimeters from the "no pain" anchor to the participant's mark, yielding a possible score ranging from 0 to 100 mm. Higher scores indicate greater pain intensity and therefore a worse outcome. Changes from baseline in the VAS score at Day 7 and Day 14 will be compared between the two treatment groups.
Baseline (N0), Day 7 (N7), and Day 14 (N14)
Secondary Outcomes (3)
Change in functional disability measured by the Neck Disability Index (NDI)
Baseline (N0), Day 7 (N7), and Day 14 (N14)
Change in cervical range of motion (ROM)
Baseline (N0), Day 7 (N7), and Day 14 (N14)
Treatment-related adverse events
From the first treatment session until Day 14
Study Arms (2)
High-Frequency Electroacupuncture at Cervical Huatuo Jiaji (EX-B2) + PEMF
EXPERIMENTALParticipants receive high-frequency electroacupuncture (100 Hz) at bilateral cervical Huatuo Jiaji (EX-B2) points corresponding to the C4-C5, C5-C6, C6-C7, and C7-T1 spinal segments combined with pulsed electromagnetic field (PEMF) therapy. Treatment is administered once daily, Monday through Friday, for two consecutive weeks (10 treatment sessions).
Conventional High-Frequency Electroacupuncture (Meridian Points) + PEMF
ACTIVE COMPARATORParticipants receive high-frequency electroacupuncture (100 Hz) at conventional meridian acupuncture points on the affected side combined with the same pulsed electromagnetic field (PEMF) therapy. Treatment is administered once daily, Monday through Friday, for two consecutive weeks (10 treatment sessions).
Interventions
Pulsed electromagnetic field (PEMF) therapy is administered according to the standardized treatment protocol during each treatment session.
High-frequency electroacupuncture (100 Hz) is applied to conventional meridian acupuncture points on the affected side according to the standardized treatment protocol.
High-frequency electroacupuncture (100 Hz) is applied to bilateral cervical Huatuo Jiaji (EX-B2) acupuncture points at the C4-C5, C5-C6, C6-C7, and C7-T1 spinal segments using standardized stimulation parameters.
Eligibility Criteria
You may qualify if:

- Contraindications to acupuncture, including skin infection or ulceration at the acupuncture site, allergy to acupuncture needles, severe needle phobia, or psychiatric disorders preventing cooperation.
- Current treatment with strong analgesics (including paracetamol/codeine combinations, tramadol, or strong opioids) or other therapies that may interfere with study outcomes.
- Implanted cardiac pacemakers or other implanted electronic medical devices (e.g., neurostimulators, implantable cardioverter-defibrillators, or insulin pumps).
- Bleeding disorders or hematologic diseases affecting coagulation.
- Benign or malignant tumors involving the treatment area or systemic malignancy.
- Participation in another interventional clinical trial.
- Inability to communicate effectively in Vietnamese.
- Pregnant women or women with suspected pregnancy.
