Outcome Measures

Primary Outcomes (6)

  • Pressure Paın Threshold Measurement

    The pressure pain threshold (PPT), the minimum amount of pressure at which the pressure sensation changes to pain, is measured with an electronic algometer (median nerve, ulnar nerve and radial nerve, C5-C6 zygapophyseal joint level (proximal), and tibialis anterior). Participants are asked to report when the sensation changes from pressure to pain. The mean of the three trials is calculated (with a 30 s rest interval in between).

  • Boston Carpal Tunnel Questionnaire - Symptom Severity Scale

    Boston Carpal Tunnel Questionnaire - Symptom Severity Scale is an 11-item questionnaire used to assess symptom severity in individuals with CTS. Each item is scored from 1 to 5. Scores range from 1 (no symptoms) to 5 (worst symptoms). The patient's symptom severity score is the average score of 11 items.

  • Boston Carpal Tunnel Questionnaire - Functional Status Scale

    Boston Carpal Tunnel Questionnaire - Functional Status Scale is an 8-item questionnaire used to assess the functional status of patients with CTS. Each item is scored from 1 to 5. Scores range from 1 (no functional deficit) to 5 (worst possible function). The patient's functional status score is the average of all 8 items.

    [at the beginning of the study] [At the end of 6 weeks] [3 months later]

  • Pain Catastrophising Scale

    The Catastrophising Pain Scale (PCS) is used to measure catastrophising in response to pain through 13 statements with four possible options from 1 "never" to 4 "always". Higher scores indicate greater catastrophised pain.

    [at the beginning of the study] [At the end of 6 weeks] [3 months later]

  • Tampa Kinesiophobia Scale

    It is a 17-question scale. The scale has a 4-point Likert scale (1= Strongly disagree, 4= Strongly agree). After reversing items 4, 8, 12 and 16, a total score is calculated. The person receives a total score between 17-68. A high score on the scale indicates a high level of kinesiophobia.

    [at the beginning of the study] [At the end of 6 weeks] [3 months later]

  • Numerical Rating Scale

    Patients rate the current pain intensity from 0 ("no pain") to 10 ("worst possible pain").

Interventions

This technique is utilized to decrease, or normalize, the body's response to particular sensations.

Group 1 (desensitisation)Group 2 (desensitisation and pain neuroscience education)

PNE is an educational intervention aiming to alter a patient's beliefs and cognitions regarding their pain experience.

Group 2 (desensitisation and pain neuroscience education)

Model Details: After determining the predominant pain phenotype in patients with CTS, patients with mixed type (neuropathic and nosiplastic pain phenotype) will be randomly divided into two groups. One group (Group 1) will receive desensitisation and the other group (Group 2) will receive desensitisation and pain neuroscience education.
