Comparison Of The Efficacy Of Interfascial Hydrodissection With A Mixture Of Lidocaine And Physiological Saline Solution With 10% Dextrose In Patients With Chronic Neck Pain

Objective: This study aimed to investigate the effects of fascial hydrodissection with 10% dextrose or lidocaine-saline on pain, neck functions, and quality of daily life in patients with chronic neck pain due to resistant myofascial trigger points in the upper trapezius muscle unresponsive to conservative treatments, and to determine whether one solution is superior to the other. Materials and Methods: This study is designed as prospective, comparative clinical study. The first group will be applied interfascial hydrodissection with 10% dextrose, and the second group with lidocaine-saline. All participants will be instructed in self-massage and stretching exercises to perform at home to support treatment efficacy. Interventions will be performed under ultrasound guidance, targeting the specified interfascial plane. Evaluations will be conducted at baseline, at 10 minutes post-treatment (VAS, ROM), and at 1-month and 3-month follow-ups (VAS, ROM, NDI, SF-12). Data will be statistically analyzied by comparing pre- and post-treatment measurements.
