Improved symptoms of complex regional pain syndrome after novel lymphatic treatment and interdisciplinary pain management

Introduction: Complex regional pain syndrome (CRPS) is a pain syndrome with no singular mechanism and no specific cure. The aim of this case report is to study the impact of Lymphatic Enhancement Technology (LET) treatment on CRPS-related symptoms. Methods: A 51 year-old female presented with a chief complaint of severe, refractory ankle pain and CRPS related to a tibial and fibular fracture sustained three years earlier. The patient completed twelve cognitive behavioral therapy sessions over a 4-week period, and eleven physical therapy sessions over a four-month period, six of which utilized LET. Results: Pain and swelling were largely unchanged with interdisciplinary treatment before the introduction of LET. A within-session change of 37.5% in pain intensity and 87.5% in ankle girth was observed immediately after the first application of LET. Three months after beginning LET treatment, the patient maintained a 43.8% improvement in pain intensity and 100% improvement in measurements of lower extremity girth and ankle range of motion. No side effects or adverse events were associated with the LET treatment. Conclusion: Swelling, pain, and mobility loss are common symptoms and features of CRPS. LET is a novel, non-invasive treatment that appears to be quite safe and effective for improving pain, swelling, and mobility loss related to CRPS.
