Complex Regional Pain Syndrome-Reflex Sympathetic Dystrophy.

Area of Science:

• Pain Medicine
• Neurology
• Rehabilitation Medicine

Background:

• Complex Regional Pain Syndrome-Reflex Sympathetic Dystrophy (CRPS/RSD) is a challenging clinical syndrome affecting a single extremity.
• Its etiology remains unknown, with peripheral changes often being more pronounced.
• Currently, no universally accepted diagnostic criteria or laboratory tests exist, relying solely on clinical presentation.

Purpose of the Study:

• To outline the clinical presentation and diagnostic considerations for CRPS/RSD.
• To discuss the current limitations in understanding the condition's pathophysiology and treatment.
• To emphasize the importance of a functional restoration approach in managing CRPS/RSD.

Main Methods:

• Diagnosis is based on clinical suspicion, considering disproportionate pain and disability, delayed recovery, and prominent autonomic changes.
• The nature of pain (sympathetically maintained or independent) is considered.
• Treatment is empiric, utilizing symptomatic techniques and focusing on rehabilitation.

Main Results:

• Clinical suspicion is key for diagnosis due to lack of objective criteria.
• The role of the sympathetic nervous system in CRPS/RSD is unclear (cause or effect).
• Psychological changes are likely secondary to the condition.

Conclusions:

• Immediate, aggressive, interdisciplinary functional restoration is the primary treatment goal for CRPS/RSD.
• Analgesic techniques may be necessary to facilitate patient compliance with rehabilitation.
• Comprehensive, functional restoration in an interdisciplinary setting is recommended.
