Pain Reduction Produced by Different Treatments in Carpal Tunnel Syndrome

December 3, 2025 updated by: Francisco Unda Solano

Pain Reduction Produced by Physiotherapy, Ibuprofen Arginine, and the Absence of Treatment, in Carpal Tunnel Syndrome

Pain reduction effects of the median nerve neural mobilization technique (a physiotherapy treatment) will be compared to those produced by a pharmaceutical treatment and the absence of treatment, in subjects who suffer carpal tunnel syndrome.

Detailed Description

The present randomized clinical trial will perform a comparison of the pain reduction effects produced by the application of median nerve neural mobilization (non invasive and non pharmaceutical physiotherapy treatment), to the pain reduction effect produced by an oral ibuprofen treatment or the lack of treatment (waiting list control group) 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 3 different groups.

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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
Manual therapy maneuver performed in the upper limb.
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.
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
Oral tablets
Other Names:
  • Spedifen
  • FASPIC

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
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.
Changes from baseline (measured immediately before the application of the first treatment) and 40 minutes after the application of the last treatment.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Upper limb function
Time Frame: Changes from baseline (measured immediately before the application of the first treatment) and at 40 minutes after the application of the last treatment.
Assessed through the Quick- Disabilities of the Arm, Shoulder and Hand (Quick- DASH) questionary, which is a shortened version of the 30-item Disabilities of the Arm, Shoulder and Hand (DASH) 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).
Changes from baseline (measured immediately before the application of the first treatment) and at 40 minutes after the application of the last treatment.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Work Status at baseline
Time Frame: Measured immediately before the application of the first 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?"
Measured immediately before the application of the first treatment
Work Status post treatment
Time Frame: Measured immediatly after the application of the last 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?"
Measured immediatly after the application of the last treatment.
Change in Work Task (Job Type)
Time Frame: Measured immediatly after the application of the last treatment.
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?"
Measured immediatly after the application of the last treatment.
Tampa Scale for Kinesiophobia-17 (TSK-17
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.
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.
Changes from baseline (measured immediately before the application of the first treatment), and at 60 minutes after the application of the last treatment.
