About this study

Effectiveness of corticosteroid and 5% dextrose versus USG-guided ozone injections in patients with carpal tunnel syndrome: Three blind randomized studies

Read the detailed description

Patients who were diagnosed with moderate CTS by EMG after clinically diagnosing CTS in our hospital's PTR clinic will be included in our study. At the beginning of the study, based on the study conducted by Wu et al. (1) who evaluated the effectiveness of dextrose prolotherapy in the treatment of patients diagnosed with carpal tunnel syndrome, the minimum number of patients required for each group was determined as 20 with a mean pain VAS change of 20%, a significance level of 0.05 and a power analysis of 95%. Considering that there may be a 20% loss during the study, it was decided to include a total of 72 patients, at least 24 patients for each group.

Patients who meet the inclusion criteria and fill out the "Informed Volunteer Consent Form" will be numbered according to their application order to the PTR clinic and will be randomized into three groups of 24 people using the "Research Randomizer" computer program, with the first group being the Ozone Group (OG), the second group being the Dextrose Group (DG) and the third group being the Corticosteroid Group (SG). Initial evaluations of the participants will be made before the injection. Each patient will receive one session of perineural injection of 1 ml betamethasone dipropionate mixed with 1 ml physiological serum to the first group; 2 ml 5% dextrose to the second group; and 2 ml 10 pg/ml ozone to the third group. The solutions to be administered will be prepared by one person in syringes that are taped shut from the outside, and then applied with a 27-gauge needle by a specialist physician who has no role in the evaluation of the results of the randomization section, from the proximal entrance of the carpal tunnel (scaphoid-psiform plane) under ultrasound guidance. In addition, each patient will wear a wrist splint for 8 hours daily during the post-treatment follow-up period. Treatment follow-up evaluations will be evaluated blindly by another specialist physician who has no role in the randomization, outcome evaluation and injection. Pre-treatment Visual Analog Scale (Global Pain), Boston Carpal Tunnel Questionnaire (Symptom Severity Scale and Functional Status Scale), Ultrasound (Measurement of median nerve cross-sectional area at pisiform level), EMG (Distal motor latency and sensory nerve conduction velocity), Hand grip strength measurement test (Dynamometer), VAS, Boston Carpal Tunnel Questionnaire, Ultrasound, Hand grip strength measurement test at the 4th week, VAS, Boston Carpal Tunnel Questionnaire, Ultrasound, Hand grip strength measurement test at the 12th week and VAS, Boston Carpal Tunnel Questionnaire, Ultrasound, Hand grip strength measurement test at the 24th week.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ozon treatmentDrug

    Each patient will receive 2 ml 10 μg/ml ozon perineural injection into the median nerve under US guidance, for 1 session.

  • Steroid treatmentDrug

    Each patient will receive 2 ml:(1 ml betamethasone dipropionate+1ml saline) perineural injection into the median nerve under US guidance, for 1 session.

  • Dextrose 5%Drug

    Also called perineural dextrose injection

    Each patient will receive 2 ml %5 dextrose perineural injection into the median nerve under US guidance, for 1 session.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analog Scale(VAS)

    Global pain:The VAS used for pain assessment consists of a line drawn in the form a ruler,and numbers from 0 to 10(with 0 as ''no pain'' and 10 as ''unbearable pain'' ) were asked to score.

    Measured: This evaluation will be made and recorded at the baseline, at the 4th, 12th and 24th weeks after the procedure.

Secondary outcomes (4)
  1. Boston Carpal Tunnel Questionnaire

    symptom severity and functional status scale

    Measured: This evaluation will be made and recorded at the baseline, at the 4th, 12th and 24th weeks after the procedure.

  2. Electromyography

    Distal motor latency and sensory nerve conduction velocity

    Measured: This evaluation will be made and recorded at the beginning and at 24th weeks

  3. Dynamometer

    Hand grip strength measurement test

    Measured: This evaluation will be made and recorded at the baseline, at the 4th, 12th and 24th weeks after the procedure.

  4. Ultrasound

    Median nerve cross-sectional area measurement at the pisiform level

    Measured: This evaluation will be made and recorded at the baseline, at the 4th, 12th and 24th weeks after the procedure.
