Residual limb pain: An evidence-based review

Area of Science:

• Medical Science
• Rehabilitation Medicine
• Pain Management

Background:

• Acquired limb loss affects over 1.5 million individuals in the US, with incidence rates exceeding 175,000 annually.
• A significant portion of amputees (25-50%) experience persistent residual limb pain, phantom limb pain, or phantom limb sensation.
• The prevalence of limb loss is projected to double in the next 30 years, highlighting an increasing public health concern.

Purpose of the Study:

• To explore the potential etiologies of residual limb pain, phantom limb pain, and phantom limb sensation.
• To review a variety of treatment options for managing post-amputation pain and sensory issues.
• To provide practitioners with insights for approaching the clinical management of these conditions.

Main Methods:

• Literature review of studies on acquired limb loss.
• Analysis of research on the pathophysiology of post-amputation pain.
• Compilation of current treatment strategies for residual and phantom limb pain.

Main Results:

• Identified multifactorial etiologies for post-amputation pain, including neuropathic and musculoskeletal factors.
• Summarized diverse treatment modalities ranging from pharmacological interventions to physical and psychological therapies.
• Highlighted the complexity and varied presentation of pain and sensory disturbances after limb loss.

Conclusions:

• Effective management of residual and phantom limb pain requires a comprehensive understanding of underlying causes.
• A multidisciplinary approach integrating various treatment strategies is often necessary for optimal patient outcomes.
• Further research is warranted to refine treatment protocols and improve quality of life for individuals with limb loss.
