Efficacy of Mirror Therapy for Complex Regional Pain Syndrome in Post-Stroke Patients
Efficacy of Mirror Therapy for Complex Regional Pain Syndrome in Post-Stroke Patients
The goal of this clinical study is to evaluate the effectiveness of mirror therapy in treating complex regional pain syndrome (CRPS) in patients after stroke using clinical assessments, electrophysiological evaluations, and ultrasonographic measurements by comparing pre- and post-treatment outcomes.
The main questions it aims to answer are:
Does mirror therapy lead to improvements in clinical outcomes in post-stroke patients with CRPS when assessed before and after treatment? Does mirror therapy reduce pain, improve motor function, and enhance functional independence based on clinical assessments? Does mirror therapy reduce swelling (edema) in the affected limb as measured by ultrasonographic evaluations? Does mirror therapy lead to changes in sympathetic nervous system function as assessed by electrophysiological evaluations?
Researchers will compare mirror therapy to sham mirror therapy (a similar procedure without therapeutic effect) to determine its effectiveness.
Participants will:
Be randomly assigned to either a mirror therapy group or a control group Receive conventional rehabilitation therapy and contrast bath treatment for 4 weeks Receive either mirror therapy or sham mirror therapy for 20 minutes daily Be evaluated before and after treatment using clinical scales, electrophysiological tests, and ultrasonographic measurements.
Complex regional pain syndrome (CRPS) is a challenging complication following stroke, characterized by pain, edema, autonomic dysfunction, and impaired motor function. It significantly affects rehabilitation outcomes and quality of life. Despite various treatment approaches, optimal management remains difficult. Mirror therapy has emerged as a non-invasive rehabilitation technique that provides visual feedback and may influence cortical reorganization and pain modulation. Additionally, it may have effects on autonomic function, particularly the sympathetic nervous system.
This prospective, randomized, single-blind study was conducted in the inpatient Physical Medicine and Rehabilitation clinic of Başakşehir Çam and Sakura City Hospital between October 2022 and October 2023. Patients with post-stroke CRPS who met the inclusion criteria were enrolled and randomly assigned to either a mirror therapy group or a control group. Both groups received a standardized conventional rehabilitation program and contrast bath therapy. The intervention group additionally received mirror therapy, while the control group received sham mirror therapy.
The aim of the study was to evaluate the clinical effectiveness of mirror therapy in post-stroke CRPS through a multidimensional approach. Clinical status, functional outcomes, electrophysiological parameters related to sympathetic nervous system function, and ultrasonographic measurements of soft tissue changes were assessed before and after the intervention period.
This study provides comprehensive evaluation of mirror therapy effects by combining clinical assessments with objective electrophysiological and imaging-based measurements. The findings are expected to contribute to the understanding of the role of mirror therapy in the management of CRPS after stroke and to support its use as an accessible and complementary rehabilitation approach.
