Study summary

Patients diagnosed with mild and moderate idiopathic CTS will be randomly divided into three groups. Patients who received 15 sessions of peloid therapy along with a home exercise program will constitute the first group. The second group will consist of patients who receive 15 sessions of paraffin bath and a home exercise program. Patients who were given only a home exercise program will be included in the third group. "Patients will be evaluated in detail in terms of clinical examination and outcomes three weeks after the end of treatment and again at three months.

Read the detailed description

Carpal tunnel syndrome (CTS) is the most common compression neuropathy caused by entrapment of the median nerve in the carpal tunnel. There are 2 methods for the treatment of CTS: conservative and surgical. Conservative treatment is mostly applied in patients with mild and moderate CTS. In this study, we aim to evaluate the efficacy of peloid therapy and kinesiobanding technique, which are conservative treatment methods. Patients will be evaluated in terms of pain, functional/symptom status, hand-finger strength, median nerve ultrasonography measurements.

Patients who were evaluated by detailed clinical examination and medical history according to the inclusion and exclusion criteria were given written informed consent and assigned to one of the three treatment groups using block randomization. Basic sociodemographic information (age, gender, body mass index, employment status, education level, marital status,etc) and clinical data (dominant hand, duration of symptoms, comorbidities, hand to be treated, Tinel/Phalen sign, pain intensity, baseline electrophysiological parameters) will be recorded. The first group will consist of patients who have received peloid therapy at 45 degrees for a total of 15 sessions of 20 minutes, 5 days a week for 3 weeks with a home-based exercise program. The second group is a program consisting of adults who receive a total of 15 sessions of 20 minutes, paraffin bath treatment and home exercise program, 5 days a week for 3 weeks. Patients who only received home-based exercise program will be included in the 3rd group. During the treatment period, patients will be allowed to take only paracetamol for pain, if necessary, except for the medications they use continuously for comorbid reasons.

All groups were evaluated by a blinded assessor based on examination findings (Tinel/Phalen tests), pain intensity (VAS), hand grip strength (HGS), finger pinch strength (FGS), the Turkish version of the Boston Carpal Tunnel Questionnaire, the 4-Question Neuropathic Pain Questionnaire (DN4),Quick DASH Score, and ultrasound measurements (median nerve cross-sectional areas [CSA]) at the proximal insertion of the carpal tunnel (at the level of the scaphoid and pisiform bones and the distal wrist crease), both after treatment (three weeks/W3) and at three months post-treatment (W12).

What researchers measure

Primary outcomes

  1. VAS pain

    A 10 cm long line is drawn, this line is divided into 10 intervals of 10 mm width, 0: no pain and 10: the most severe pain is explained, and the patient is asked to mark the value corresponding to the resting pain and the pain during movement on the scale.

    Time frame: baseline, week 3 and week 12

  2. The Boston Carpal Tunnel Syndrome Questionnaire

    The Turkish version of the Boston Carpal Tunnel Questionnaire score. It is used to evaluate the symptom severity and functionality of the patients. BCTQ is a questionnaire consisting of 2 parts: symptom severity scale (SSS) and functional status scale (FSS). Each item in both sections has 5 different answers that score between 1 and 5. The mean score is obtained by dividing the total score by the number of questions and ranges from 1 to 5, with a higher score indicating severe symptom.

    Time frame: baseline, week 3 and week 12

Secondary outcomes

  1. Hand grip strength

    Following the definitions outlined in the literature, HGS will be measured using Jamar hand dynamometers. The patients will be asked to squeeze the dynamometer three times with maximum strength, allowing 30-60 seconds of rest between each attempt. The average force (in pounds/kg) will then be recorded.

    Time frame: baseline, week 3 and week 12

  2. Finger pinch strength

    Following the definitions outlined in the literature, FGS will be measured using Baseline pinch dynamometers. The patients will be asked to squeeze the dynamometer three times with maximum strength, allowing 30-60 seconds of rest between each attempt. The average force (in pounds/kg) will then be recorded.

    Time frame: baseline, week 3 and week 12

  3. Douleur Neuropathique 4

    The DN4 is a short and simple screening test designed to help distinguish neuropathic pain from other types of pain, such as nociceptive pain. Neuropathic pain is assessed with four questions. The first two questions are based on the patient interview and the other two questions are based on the clinical examination.

    Time frame: baseline, week 3 and week 12

  4. Quick DASH Score

    The purpose of the QuickDASH is to use 11 items to measure physical function and symptoms in people with any or multiple musculoskeletal disorders of the upper limb. The QuickDASH is a widely used reference of self-reported disability.

    Time frame: baseline, week 3 and week 12

  5. Ultrasonographic evaluation of the median nerve

    Ultrasonographic evaluation of the median nerve will be performed with a LA2-14A transducer /superficial linear probe (Samsung). The cross-sectional areas (CSA) of the median nerve at the proximal inlet of the carpal tunnel will be recorded. To identify the entrance of the carpal tunnel, measurements will be taken at the level of the distal wrist crease, at the scaphoid and pisiform bones. The assessments were conducted with the patients seated, facing the clinician, with their elbow bent at approximately 90˚, forearm in a supine position, and fingers in a semiflexed posture. Measurements were obtained using the manual tracing feature of the ultrasound device, excluding the hyperechoic nerve sheathThe CSA (mm2) will be determined. The average of the three measurements will be recorded.

    Time frame: baseline, week 3 and week 12
