About this study

In clinical practice, carpal tunnel syndrome (CTS) is the common disease of peripheral neuropathy and usually happened to female, mid-age population, overweight persons, and those who overused their hands for work or production. Some research claimed this might be correlated to anatomical characteristics such as the longer anteroposterior diameter or smaller cross section area of the wrist. Preliminary symptoms often start with sensory domain (pain, tingling, paresthesia and especially night awakening due to symptoms mentioned above) and then progress to motor domain (thenar muscle atrophy and clumsiness) if left untreated.

Depending on the severity, patient's willingness and convenience, there are many options for CTS. For those whose symptoms are mild to moderate, conservative therapies are usually the first choice, including physiotherapies, local injection and night splints. Local steroid is proven to be effective to relieve the symptoms of CTS shortly up to 3 months. However, the effects will decline gradually and repetitive injections is suggestive. The patients with severe symptoms which comprise thenar muscle atrophy will be advised to receive decompression surgery.the surgery can alleviate the illness with high success rate up to 70%. Unfortunately, there are still patients who will relapse or undergo side effects, for example, finger weakness.

In recent years, acupuncture researches focused on CTS intervention have been outgrowing and promising. Whereas, there are still lack of evidence which stands for the therapeutic effects comparing with local steroid injection. This limits the built-up of suspect mechanism of acupuncture intervention for CTS.

This is a preliminary, randomized and single-blinded study which started since 2016 and last for a year. The investigators utilize ultrasound to guide the depth of needle penetration which prevents unnecessarily tissues injury such as artery or dry needle injury. This procedure also guarantees the needles lie directly on the upper surface of the median nerve. One group will receive electrical stimulation and another won't. The investigators use electromyography, cross-section area of median nerve, visual analog scale, Boston Carpal Tunnel Syndrome Questionnaire, six-item scale, The disabilities of the arm, shoulder and hand score and Jamar grip dynamometer as outcome measurements. The results gathered from two experimental groups will be compared with the data from the control group whose participants only receiving local steroid injection once in the first week. The participants are all above 18 years old and complain of illness for a least 3 months without any surgery or local injection for a least 1 year. The investigators set up strict exclusive criteria and sample size estimation is 70.

Study groups in NCT02870673
Study groupRoleWhat they receive
Injection of Shincort 0.5 ml and Xylocaine 0.5ml mixtureActive comparatorIn the first week of recruitment, this group will receive the local injection around the distal wrist crease with mixture of Shincort Inj(10mg/ml) 0.5 ml and xylocaine(20mg/ml) 0.5 ml only one time. The ultrasound-guided procedure is performed by the orthopedic physician.
Receives: Drug: SHINCORT; Drug: XYLOCAINE
sham electroacupunctureExperimentalIn this group, the participants receive acupuncture treatment and only 2 minutes electrical stimulation. Each needle insertion depth and position are confirmed by the ultrasound. The procedure makes sure that needle pin is directly placed on the median nerve and prevent nerve penetration. Then the electrical stimulator is connected to the needles as cathode and anode and is turned on to the intensity which can induce thenar muscle contraction or reach the upper limit of the participant. After 2 minutes, the stimulator will turn off spontaneously and the participant will not be informed. The whole course will cost 20 minutes after needles are pulled out. Every participant is asked to receive 1 treatment per week in the consecutive 3 months(total 12 times).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. pain assessed on visual analog scale

    Measured: 24 weeks

  2. Boston Carpal Tunnel Syndrome Questionaire

    Measured: 24 weeks

  3. The 6-item CTS symptoms scale

    Measured: 24 weeks

  4. cross sectional area(CSA) of the median nerve

    CSA of the median nerve below the distal wrist crease which is measured by the ultrasound(transverse view )

    Measured: 24 weeks

  5. hand grip power

    Jamar Hand grip Dynamometer as the measuring tool

    Measured: 24 weeks

  6. The Disabilities of the Arm, Shoulder and Hand (DASH) Score

    Measured: 24 weeks

  7. compound muscle action potential(CMAP)

    The CMAP is a summated voltage response from the individual muscle fibre action potentials and measured in millivolts (mV).

    Measured: 24 weeks

  8. Wrist-palm sensory nerve conduction velocity(Wrist-palm SNCV)

    Wrist-palm SNCV (m/s) = distance between stimulation site 1 and site 2 (mm)/[latency wrist- latency palm(ms)].

    Measured: 24 weeks

  9. motor nerve conduction velocity(MNCV)

    MNCV (m/s) = distance between stimulation site 1 and site 2 (mm)/[latency site 2 - latency site 1 (ms)].

    Measured: 24 weeks

  10. sensory nerve action potential(SNAP)

    The sensory nerve action potential (SNAP) is obtained by electrically stimulating sensory fibres and recording the nerve action potential at a point further along that nerve.

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing SHINCORT, XYLOCAINE and electroacupuncture in people with Carpal Tunnel Syndrome, run by Taipei Medical University Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact You-Jen Tang, MD (+886932182791, 9502060@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pain assessed on visual analog scale (time frame: 24 weeks). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2016.
