Study summary

In the present investigation the pain reduction effects of a physiotherapy technique combined with gabapentin and ibuprofen arginine will be compared to those produced by an ibuprofen arginine (only) 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 (group 1) the pain reduction effects produced by the application of a non invasive and non pharmacological median nerve neural mobilization (physiotherapy treatment) combined with a pharmaceutical oral gabapentin treatment versus (group 2) median nerve neural mobilization (physiotherapy treatment) combined with a pharmaceutical oral ibuprofen arginine treatment, to those effects produced by (group 3) ibuprofen arginine (only) treatment. 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 2 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 signs.
  • 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 and oral gabapentin

    Median nerve neural mobilization, non pharmaceutical, non invasive, physiotherapy technique; which consists of a passive and repetitive upper limb movement that seeks to induce median nerve gliding and incursions against surrounding connective tissue. Subjects will be treated 5 days per week during a total time lapse of 2 weeks. Additionally, subjects will be treated with a Gabapentin 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 2 weeks.

    Other: Median nerve neural mobilization · Drug: Gabapentin 300mg

Subjects will be treated 5 days per week during a total time lapse of 2 weeks. Additionally, subjects will be treated with an ibuprofen arginine maximum dose of 1200 mg per day, subdivided in 3 intakes of 400 mg each 8 hours during a time lapse of 2 weeks.

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. 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.
