Clinical Efficacy of Acupuncture and Paraffin Wax Therapy in the Treatment of Carpal Tunnel Syndrome

6. november 2026 opdateret af: letieunhat, The University of Health Sciences, VNU-HCM

The goal of this clinical trial is to learn if Paraffin wax therapy combined Electroacupuncture works to treat capal tunnel syndrome patients. It will also learn about the safety of Paraffin wax therapy combined Electroacupuncture. The main questions it aims to answer are:

  • To compare the improvement in symptoms and functional status among three treatment groups: electroacupuncture alone, paraffin wax therapy alone, and combined electroacupuncture-paraffin wax therapy in patients with carpal tunnel syndrome.
  • To identify adverse events associated with each treatment modality (electroacupuncture, paraffin wax therapy, and combined electroacupuncture-paraffin wax therapy) in patients with carpal tunnel syndrome.

Participants will:

  • Following the treatment sessions: 5 days per week, total 3 sessions.
  • To be examined by an investigator and answer some questions when admitted and after 3 treatment sesions.

Beskrivelse

Inclusion Criteria:

  • Presence of carpal tunnel syndrome symptoms within the median nerve distribution, lasting for at least 3 months, with a CTS-6 score more or equal to 12.
  • Confirmed primary carpal tunnel syndrome of mild-to-moderate severity via electrodiagnostic testing (electrodiagnostic neuromuscular study), corresponding to Bland grades 2-3.
  • No history of carpal tunnel release surgery and no indication for emergency/urgent surgical intervention.
  • Willingness to participate in the study and ability to fully comply with the treatment protocol.

Exclusion Criteria:

  • Secondary carpal tunnel syndrome or confounding neurological/rheumatological conditions: Polyneuropathy; cervical radiculopathy; brachial plexus injury; thoracic outlet syndrome; active rheumatoid arthritis or gout; uncontrolled hypothyroidism; prior wrist trauma or anatomical deformity.
  • Severe carpal tunnel syndrome (Bland grade more than or equal to 4): Thenar muscle atrophy; abductor pollicis brevis or opponens pollicis muscle strength < 4/5; or electrodiagnostic evidence of axonal damage.
  • Prior interventions: History of carpal tunnel release surgery; local corticosteroid injection or systemic corticosteroid use within the past 3 months; or treatment with electroacupuncture, paraffin wax therapy, or specialized physical therapy within 4 weeks prior to enrollment.
  • Local and dermatological contraindications: Open wounds, dermatitis, or active infection at the intervention site; paraffin allergy; loss of protective sensation or thermal (hot-cold) discrimination; severe peripheral vascular disease.
  • Implanted electronic devices and bleeding disorders: Implanted cardiac pacemaker, defibrillator, or other electronic medical devices; clinically significant coagulopathy or conditions compromising safety during electroacupuncture.
  • Uncontrolled cardiovascular conditions: Uncontrolled hypertension, defined as blood pressure more or equal to 180/110 mmHg upon re-measurement; unstable cardiovascular disease, uncontrolled arrhythmia, or decompensated heart failure.
  • Severe systemic comorbidities: Decompensated liver disease or hepatic disease with coagulopathy; chronic kidney disease (CKD) stage 4-5; uncontrolled diabetes mellitus or diabetic polyneuropathy; active malignancy or ongoing chemotherapy.
  • Other exclusion factors: Pregnant women; patients with acute illnesses, cognitive impairment, or inability to comply with the study protocol.

Intervention / Behandling
Eksperimentel: Electroacupuncture and Paraffin Wax Group

Participants in this group will receive both paraffin wax therapy and electroacupuncture following this order: Paraffin wax therapy - 10 minutes break - Electroacupuncture.

Electroacupuncture. Electroacupuncture: Acupuncture will be performed at the Dailang (PC7), Neiguan (PC6), Hegu (LI4), and Yangxi (LI5) acupoints until the deqi sensation is achieved. Following needle insertion, electrical stimulation will be delivered using an electroacupuncture device.

Paraffin wax therapy: Protocol according to Decision No. 3553/QD-BYT dated November 14, 2025, of the Ministry of Health, issuing "Technical Guidelines for Rehabilitation Procedure - Volume 1, Procedure 18 - Paraffin Wax Therapy".

Aktiv komparator: Paraffin Wax Group

Paraffin wax therapy group will do paraffin wax therapy only in 3 sessions

Foranstaltningsbeskrivelse
Tidsramme
Boston Carpal Tunnel Questionnaire's symptom severity scale
Tidsramme: Baseline (pre-intervention) and after 3 weeks

This questionnaire includes 11 items assessing symptom severity, each scored on a 5-point scale from 1 (mildest) to 5 (most severe).

Total raw score from 11 to 55, final score 1 to 5 (Final score = Raw score / 11). Higher score means greater symptom severity and worse impairment. A score of 1 indicates no symptoms, while a score of 5 indicates severe, constant symptoms.

Baseline (pre-intervention) and after 3 weeks
Functional Status Scale - BCTQ-FSS
Tidsramme: Baseline (pre-intervention) and after 3 weeks

This questionnaire includes 8 items assessing function. Each question score from 1 to 5 (1 = No difficulty, 5 = Cannot perform at all due to symptoms) Total raw score is from 8 to 40. Final score is 1 to 5 (Final score = raw score / 8). Higher score means greater functional disability and impairment. A score of 1.0 represents normal hand function, while 5.0 represents complete inability to perform basic tasks.

Tidsramme
Phalen, Tinel test
Tidsramme: Baseline (pre-intervention) and after 3 weeks

Phalen's Test: Positive if tingling, numbness, or pain in the median nerve distribution is reproduced or worsened within 60 seconds of maximal wrist flexion.

Tinel's Sign: Positive if tapping directly over the median nerve at the flexor retinaculum of the wrist elicits a sensation of tingling or an electric shock-like feeling radiating into the fingers.

Baseline (pre-intervention) and after 3 weeks
Muscle strength assessment
Tidsramme: Baseline (pre-intervention) and after 3 weeks

Arm Muscle strength assessment, scale from 0 to 5.

High Score (Grade 5): Normal muscle strength. The muscle can move the joint through its full range of motion against strong manual resistance applied by the examiner.

Low Score (Grade 0): Complete paralysis. No visible muscle contraction or movement occurs.

Baseline (pre-intervention) and after 3 weeks
Side effects
Tidsramme: periprocedurally

Unwanted side effects (or adverse events) of electroacupuncture, paraffin wax bath, and the combination of electroacupuncture and paraffin wax bath during the study period.
