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

- 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.

Experimenteel: 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". |

Boston Carpal Tunnel Questionnaire's symptom severity scale
Tijdsspanne: 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
Tijdsspanne: 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. |

Phalen, Tinel test
Tijdsspanne: 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
Tijdsspanne: 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. |
