About this study

Official title: Pain Reduction and Changes in Upper Limb Function Produced by Physiotherapy, Ibuprofen Arginine, Gabapentin and the Absence of Treatment, in Carpal Tunnel Syndrome

In the present investigation the pain reduction effects of a physiotherapy technique will be compared to those produced by two different pharmaceutical treatments and also by the absence of treatment, in subjects who suffer the signs and symptoms of carpal tunnel syndrome.

Read the detailed description

The present randomized clinical trial will perform a comparison of the pain reduction effects produced by the application of a non invasive and non pharmacological median nerve neural mobilization (physiotherapy treatment), to those effects produced by an oral ibuprofen arginine pharmacological treatment, an oral gabapentin pharmacological treatment and the lack of treatment in subjects diagnosed with carpal tunnel syndrome. Additionally, effects over the functionality of the affected upper limb will be evaluated and compared. Subjects will be invited to participate and randomly allocated to 4 different groups.

Study groups in NCT04025203
Study groupRoleWhat they receive
Median nerve neural mobilizationExperimentalNon pharmaceutical, non invasive, physiotherapy technique; which consists of a passive and repetitive upper limb movement that seeks to induced median nerve gliding and incursions against surrounding connective tissue. Subjects will be treated 5 days per week during a total time lapse of 4 weeks.
Receives: Other: Median nerve neural mobilization
Ibuprofen arginineActive comparatorOral tablet pharmaceutical treatment. Participants will be treated with a maximum of 1200 mg per day, subdivided in 3 intakes of 400 mg each 8 hours during a time lapse of 4 weeks.
Receives: Drug: Ibuprofen Arginine
GabapentinActive comparatorOral capsule pharmaceutical treatment. Participants will be treated with a maximum of 600 mg per day, subdivided in 2 intakes of 300 mg each 12 hours during a time lapse of 4 weeks.
Receives: Drug: Gabapentin
Control groupNo interventionWaiting list control group. Participants that belong to the no intervention arm will be assigned to a waiting list to receive treatment. The participants will not receive treatment for carpal tunnel syndrome during a time lapse of 4 weeks. After this period of time, participants will begin the best treatment available.

What is being measured

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

  1. Distal upper limb pain

    Assessed through the visual analog scale (VAS). The VAS is a psychometric response scale. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured.The VAS is the most frequently used method to assess pain intensity. The scale will be displayed as a horizontal 10-cm line labelled at each end by descriptors such as 'no pain' (the minimum and best outcome possible) and 'worse pain ever' (maximum and worst outcome possible). The participant will mark the line to indicate pain severity and it is simply quantified by measuring the distance in centimeters from 0 (no pain) to the patient's marked rating.

    Measured: Changes from baseline (measured immediately before the application of the first treatment) and 40 minutes after the application of the last treatment.

Secondary outcomes (1)
  1. Upper limb function

    Assessed through the QuickDASH questionary, which is a shortened version of the 30-item DASH (Disabilities of the Arm, Shoulder and Hand) instrument.The instrument administered to the participants will be a self-report questionnaire, that will rate the difficulty and interference of daily life on a 5 point Likert scale. At least 10 of the 11 items must be completed for a score to be calculated and the scores range from 0 (no disability) to 100 (most severe disability).

    Measured: Changes from baseline (measured immediately before the application of the first treatment) at 40 minutes after the application of the last treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Median nerve neural mobilization, Ibuprofen Arginine and Gabapentin in people with Carpal Tunnel Syndrome, run by Francisco Unda Solano at 1 site in Venezuela.

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 5 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 10 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Venezuela. Whether a site is taking part right now should be confirmed with that site. See every site.

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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Distal upper limb pain (time frame: Changes from baseline (measured immediately before the application of the first treatment) and 40 minutes after the application of the last treatment.). 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 NCT04025203, which also lists 22 linked publications.

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 10 Dec 2025.
