Combined Effect of Insulin and Sodium Hyaluronate Injection Guided by Ultrasound in Carpal Tunnel Syndrome

Early Phase 1UnknownNCT04142411

Assiut University90 enrolled

Overview

Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy with involving compression of the median nerve in the carpal tunnel. The technique of perineural injection therapy (PIT) is now commonly used for peeling the nerve from surrounding soft tissue (called nerve hydrodissection), which may help to reduce neuro-inflammation, ischemic damage and allow impulse transmission. The objective of this study is to evaluate the efficacy of ultrasound guided insulin plus Sodium Hyaluronate injection in reducing symptoms caused by carpal tunnel syndrome.

In this randomized clinical trial, 90 patients with both a clinical and electromyographic diagnosis of mild to moderate carpal tunnel syndrome will be recruited from Assiut University Hospital (AUH). After obtaining written informed consent, patients will be randomized into three groups. Group A, patients will receive ultrasound-guided PIT with 10 IU of crystalline insulin; Group B, patients will receive ultrasound-guided PIT with 20 mg of Sodium Hyaluronate; Group C, patients will receive ultrasound-guided PIT with 10 IU of crystalline insulin and 20 mg of Sodium Hyaluronate. The primary outcome will be the Boston Carpal Tunnel Syndrome Questionnaire - Symptom Severity Scale at baseline, 1 month and 3 months post injection. All participants, investigator, outcomes assessor will be blinded (Triple blind)

Outcomes

Primary Outcomes

Boston Carpal Tunnel Syndrome Questionnaire - Symptom Severity Scale

Boston carpal tunnel syndrome questionnaire - SSS is patient-based questionnaire for measurement of CTS severity which include11 questions to evaluate the symptom severity. Each question ranges from 1 to 5 with a higher score indicating a higher degree of disability.
