Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Participants must be medically diagnosed with unilateral carpal tunnel syndrome (with confirmative electrodiagnostic findings).
  • Full understanding of written and spoken Spanish (language).
  • Participants must freely consent to participate.
  • The presence of positive Phalen and Tinel sign.
  • The presence of carpal tunnel syndrome signs and symptoms

Exclusion criteria

Exclusion Criteria:

  • The lack to meet inclusion criterions, the presence of cognitive impairment, tumors, cancer, recent (affected) upper limb surgery or trauma, pregnancy, metabolic neuropathy, obesity ( over 30), participants who are not employed, deformities of the (affected) upper limb, recent skin injuries or infections (in the affected upper limb), inflammatory conditions or flu type symptoms, allergy to gabapentin, allergy to ibuprofen arginine, and also: participants must not be (during the present investigation) under any type of pain reducing treatment (conservative, homeopathic, invasive or not invasive).
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Study arms

  • Experimental
    Median nerve neural mobilization

    Non 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.

    Other: Median nerve neural mobilization

  • Active comparator
    Ibuprofen arginine

    Oral 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.

    Drug: Ibuprofen Arginine

  • Active comparator
    Gabapentin

    Oral 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.

    Drug: Gabapentin

  • No intervention
    Control group

    Waiting 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.

Interventions

What researchers measure

Primary outcomes

  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.

    Time frame: 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. 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).

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

Other outcomes

  1. Work Status at baseline

    This measure is performed through the employed participant (full-time or part-time) answering in a dichotomous manner (yes or no) the question: "Do you currently work?"

    Time frame: Measured immediately before the application of the first treatment

  2. Work Status post treatment

    This measure is performed through the employed participant (full-time or part-time) answering in a dichotomous manner (yes or no) the question: "Do you currently work?"

    Time frame: Measured immediatly after the application of the last treatment.

  3. Change in Work Task (Job Type)

    This measure is performed through the employed participant (full-time or part-time) answering in a dichotomous manner (yes or no) the question: "Did you change your job type or task?"

    Time frame: Measured immediatly after the application of the last treatment.

  4. The Tampa Scale for Kinesiophobia-17 (TSK-17)

    The Tampa Scale for Kinesiophobia-17 (TSK-17) is a 17-item questionnaire designed to assess the fear of movement and re-injury (kinesiophobia). Items are rated on a 4-point Likert scale (ranging from "strongly disagree" to "strongly agree"), yielding a total score that reflects the severity of pain-related fear avoidance beliefs. It's a widely used and vailidaded clinical and research instrument. The standard total score range for the Tampa Scale for Kinesiophobia (TSK-17) is 17 to 68. It is calculated by summing 17 items, each scored 1-4, with four items reverse-scored. Higher scores indicate greater fear of movement

    Time frame: Changes from baseline (measured immediately before the application of the first treatment), and at 60 minutes after the application of the last treatment.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2019 to primary completion in Nov 2019, 3 months.

Of 28 non-industry phase 4 interventional studies under Carpal Tunnel Syndrome, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 19. This study's 3 months is below that.

Counting every sponsor, half of 28 studies reached it within 7 months; a quarter within 3 and three quarters within 19.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 10, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
