If you’ve had a lower limb amputation, you may be living with more than one kind of pain. A new study suggests that treating them all the same way could be part of the problem.
Researchers at the University of Colorado Anschutz have uncovered a significant gap in the assessment and management of post-amputation pain. Their research indicates that pain following a lower limb amputation is not a singular, uniform condition but comprises various distinct experiences that vary with activity level and prosthetic design.
The study, published in the journal PM&R, analyzed 83 adults with unilateral above-knee and below-knee limb loss. Participants shared their pain levels both at rest and during real-world activities to accurately represent daily life challenges.
Three Types of Pain, Three Different Patterns
Most study participants experienced multiple types of pain. The researchers categorized them into three groups:
-
Phantom Limb Pain – pain felt in the missing part of the limb.
-
Residual Limb Pain – pain in the remaining limb.
-
Musculoskeletal Pain – back, hip, or joint pain resulting from altered walking mechanics.
Each type responded differently to physical activity, a distinction that gets lost when clinicians rely on a single overall pain score.
Musculoskeletal pain increased significantly during walking and daily movement in people using prosthetic sockets, suggesting that improvements in gait and load distribution may help alleviate this pain. Residual limb pain was closely associated with difficulty completing daily tasks and reduced quality of life among socket prosthesis users—highlighting the impact of socket pressure on overall well-being. Meanwhile, phantom limb pain showed a more variable pattern and did not consistently increase with activity, particularly in individuals using osseointegrated prostheses.
Socket vs. Bone-Anchored Prostheses
The study also compared individuals with traditional socket prostheses to those with bone-anchored limb systems, finding differences in pain experiences in both intensity and response to activity.
This distinction is important for treatment. Socket users with increased pain during activity might benefit from gait adjustments or prosthetic fit changes—interventions that may not be needed for someone primarily affected by phantom limb pain.
The Problem With a Single Pain Score
Lead author Eric J. Earley, Ph.D., assistant research professor of orthopedics at the CU Anschutz School of Medicine, argued that distinguishing pain types is essential. Treating all post-amputation pain as a single category may cause clinicians to miss the actual source of the problem.
Danielle Melton, M.D., the senior author of the study and a professor of physical medicine and rehabilitation, as well as co-director of amputation medicine and rehabilitation at CU Anschutz's Osseointegration and Limb Restoration Program, highlighted that untreated or poorly managed pain can restrict mobility, delay returning to work, disturb sleep, and greatly diminish quality of life. This underscores an urgent need for more accurate, personalized treatment strategies.
One way to help you and your healthcare provider determine what type of pain you’re experiencing is to keep a symptom journal.
What This Means for Amputee Care
The researchers recommended that clinicians assess each type of pain separately. A more thorough evaluation may help guide precise prosthetic adjustments, gait-centered physical therapy, targeted treatments for phantom limb pain, and rehab for musculoskeletal strain.
Dr. Melton observed that, for many patients, pain influences their ability to remain active and independent. She added that a more thorough pain assessment could result in better treatment choices and enhance daily functioning for individuals living with limb loss.
