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.\n\nThe 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.\n\nParticipants 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.\n\nThe 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.",[62,63],"Low Back Pain","Amputation",[65,66,67,68,69,70,71,72],"Chronic low back pain","Combat-related amputation","Amputation level","Transtibial amputation","Transfemoral amputation","Bilateral amputation","Prosthesis use","Rehabilitation","NOT_YET_RECRUITING","2026-05-30",{"date":76,"type":77},"2026-06-04","ACTUAL",{"date":79,"type":57},"2026-09-15",{"date":79,"type":57},{"name":5,"class":6},1]
