About this study

The purpose of this study is to compare the efficacy of combining a wrist orthosis with either ultrasound therapy or paraffin bath therapy in treating carpal tunnel syndrome patients.

Read the detailed description

The purpose of this exploratory study is to compare the combination of a wrist orthosis with either ultrasound therapy or paraffin bath therapy in the treatment of carpal tunnel syndrome patients. We hypothesized that ultrasound therapy might be more effective than paraffin therapy because it provides both thermal and nonthermal effects.

Being tested
ultrasound, paraffin therapy
Medical subject headings
Carpal Tunnel Syndrome

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ultrasoundDevice

    Patients in the ultrasound therapy group were treated with US therapy for 5 minutes each session, twice per week for 8 weeks.

  • paraffin therapyProcedure or surgery

    Patients in the paraffin therapy group were treated with the dip-and-wrap method of paraffin bath therapy in the hospital twice per week for 8 weeks. The temperature of the paraffin bath was maintained at approximately 55°C

What is being measured

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

  1. Functional Status Scale of the Boston Carpal Tunnel Syndrome Questionnaire

    All of the answers were scored from 1 to 5 according to the patient's clinical condition, such that 1 indicated no symptoms, and 5 indicated the most severe symptoms.

    Measured: 8 weeks

Secondary outcomes (6)
  1. Symptom Severity Scale of the Boston Carpal Tunnel Syndrome Questionnaire

    All of the answers were scored from 1 to 5 according to the patient's clinical condition, such that 1 indicated no symptoms, and 5 indicated the most severe symptoms.

    Measured: 8 weeks

  2. Pain Scale

    The pain VAS is a continuous scale comprised 10 centimeters (100 mm) in length. 0 indicate no pain, 100 indicate maximum pain.

    Measured: 8 weeks

  3. Difference of Monofilament Sensory Test (Before and After Treatment)

    The Semmes-Weinstein monofilament sensory test was measured by applying force-calibrated nylon filament to the fingertips with the wrist in a neutral supine position A weighted score from 1 to 5 was acquired according to each filament's calculated force . We recorded the scores from seven sample areas in each hand and summed the scores to analyze as a continuous variable.Higher score indicate decreased finger tip sensation with increased disesase severity.Total score range:7 -35.

    Measured: 8 weeks

  4. Difference in Palmar Pinch Power Test (Before and After Treatment)

    Palmar pinch strength was measured by pressing the thumb and the index finger tip against a standard dynamometer. This procedure was repeated 3 times measuring in kilograms, and a mean score was obtained. Higher score indicate better pinching strength, which indicate less disease severity. Score range: minimum :0 kilogram

    Measured: 8 weeks

  5. Difference in the Distal Sensory Latencies of the Median Nerve (Before and After Treatment)

    A standard distance (14 centimeter) was maintained between the stimulator and recording electrodes for the sensory nerve conduction studies. Increased distal latency indicate delay of nerve conduction, which imply poor disease progress.

    Measured: 8 weeks

  6. Difference in the Distal Motor Latencies of the Median Nerve (Before and After Treatment)

    Median motor nerve conduction and distal motor latency were measured by placing a stimulating electrode at the wrist and a recording electrode on the abductor pollicis brevis muscle 8 centimeter from the stimulus electrode. Increased distal latency indicate delay of nerve conduction, which imply poor disease progress.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing ultrasound and paraffin therapy in people with Carpal Tunnel Syndrome, run by Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation.

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 1 inclusion and 1 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: finished, as of the sponsor's last update on 24 Feb 2021. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Feb 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Functional Status Scale of the Boston Carpal Tunnel Syndrome Questionnaire (time frame: 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02278289, which also lists 1 linked publication.

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 24 Feb 2021.
