Conditions
Interventions
In this study, we apply STIMPOD NMS 460 to generate Non-invasive PRF (pulsed radiofrequency). Non-invasive PRF will generate alternating current, which induce electromagnetic field. Electromagnetic fi

Inclusion criteria
Inclusion criteria: 1. Age 18-60 years old 2. had symptoms of CTS at least 3 months 3. were diagnosed by electrophysiologic test and classified as mild or moderate degree CTS (AAEM minimonograph#26) Mild CTS: prolonged (relative or absolute) sensory or mixed NAP distal latency (orthodromic, antidromic, or palmar) with or without SNAP amplitude below the lower limit of normal. Moderate CTS: abnormal median sensory latencies as above, and (relative or absolute) prolongation of median motor distal latency.
Exclusion criteria
Exclusion criteria: 1. had underlying metabolic disorder such as diabetes mellitus, thyroid disease, kidney disease 2. Inflammation of joints in hand and wrist such as rheumatoid arthritis 3. had condition mimicking CTS such as cervical radiculopathy, polyneuropathy, proximal median neuropathy, or ulnar neuropathy 4. Previous fracture around wrist and hand or wrist-hand deformity that effect hand function 5. had a thenar hypotrophy or APB weakness or intolerable pain/numbness 6. were diagnosed by electrophysiologic test and classified as severe degree CTS (AAEM minimonograph#26) 7. Previous CTS surgical release, wrist surgery or corticosteroid injection 8. had a cardiac pacemaker, implanted defibrillator, implanted metallic or electronic device 9. Pregnancy

| Functional Status Scale (FSS) Thai version Boston questionnaire at 2, 3, 6 and 12-week follow-up FSS has 8 questions.Each question on a scale of 1 to 5 points.A final score is the sum of the individual scores.A higher score indicates that the symptoms of CTS interfere ADL more than a lower score.,Pain score at 2, 3, 6 and 12-week follow-up Numeric Rating Scale (NRS) ,Electrophysiologic parameter of median nerve at 6-week follow-up Electrodiagnosis study,Semmes-Weinstein Monofilament (SWMF) at 6-week follow-up The sensibility testing with Semmes-Weinstein monofilament on palmar side of all distal fingers. Assessor will record the smallest size monofilament, which the participant indicates a correct response | — |
