Reflex sympathetic dystrophy: the clinician's perspective
1Department of Physical Therapy, University of Mississippi Medical Center, Jackson, USA.
Summary
Reflex sympathetic dystrophy (RSD) involves peripheral inflammation, spinal neuron sensitization, and supraspinal influences. Understanding these etiological factors is key to developing effective measurement and "hands off" treatment strategies for RSD.
Area of Science:
- Neuroscience
- Pain Management
- Physiology
Background:
- Reflex sympathetic dystrophy (RSD) is a complex condition with debated etiology.
- Existing theories categorize RSD causes into peripheral, spinal, and supraspinal mechanisms.
Purpose of the Study:
- To review and categorize current theories on the etiology of reflex sympathetic dystrophy (RSD).
- To propose measurement and treatment strategies targeting the different etiological levels of RSD.
Main Methods:
- Review of existing literature on reflex sympathetic dystrophy (RSD) etiology.
- Categorization of theories into peripheral, spinal, and supraspinal pathways.
- Proposal of diagnostic (static and stress tests) and therapeutic strategies.
Main Results:
- Peripheral pathophysiology involves inflammatory responses, axon reflexes, and neuropeptide release.
- Spinal mechanisms include sensitized nociceptive neurons due to chronic pain.
- Supraspinal influences are linked to physical-emotional diathesis and autonomic arousal.
Conclusions:
- RSD etiology is multifactorial, involving peripheral, spinal, and supraspinal components.
- Integrated measurement techniques (static and stress tests) are needed for comprehensive assessment.
- A 'hands off' treatment approach addressing pain, sensory thresholds, vasomotor function, and motion is suggested.
