Leg amputation level linked to chronic back pain in veterans
NCT ID NCT07626294
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 300 adults with combat-related lower limb amputations to see how the level of amputation (below knee, above knee, or both legs) relates to chronic low back pain. Researchers will measure pain intensity, disability, and rehabilitation progress over time. The goal is to identify who is at higher risk for persistent back pain and improve care after limb loss.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Participants will include adult patients with combat-related lower limb amputations undergoing rehabilitation and prosthetic recovery. The study population will consist of individuals with unilateral transtibial amputation, unilateral transfemoral amputation, or bilateral lower limb amputation. Participants will be recruited from military rehabilitation and trauma centers specializing in post-amputation care. The study aims to evaluate the relationship between amputation level and chronic low back pain during long-term rehabilitation and prosthesis use.
