The Association Between Amputation Level and Chronic Low Back Pain After Combat-Related Amputation

Patients with combat-related lower limb amputations frequently experience chronic low back pain during long-term rehabilitation and prosthetic use. Altered biomechanics, asymmetric loading, gait disturbances, and changes in spinal alignment after limb loss may contribute to the development of persistent back pain. The severity and characteristics of low back pain may vary according to the level of amputation. The LEVEL-BACK Study is a prospective observational study designed to evaluate the relationship between amputation level and chronic low back pain after combat-related amputation. Participants with different levels of lower limb amputation will undergo clinical assessment of low back pain intensity, functional limitations, prosthesis use, and rehabilitation outcomes during follow-up. The goal of the study is to improve understanding of how amputation level influences chronic low back pain after combat-related limb loss and to identify patients at increased risk for persistent spinal pain during rehabilitation.
