Sagittal Spinopelvic Parameters in Patients With Lower Extremity Amputation

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to investigate the relationship between sagittal spinopelvic parameters and low back pain and quality of life in individuals with lower extremity amputation.

Detailed Description
-----------------
Low back pain is one of the secondary health problems that negatively affect functionality, independence and quality of life in individuals with lower extremity amputation. The prevalence of low back pain was reported to be higher in individuals with lower extremity amputation (52-89%) than in the non-amputee population (12-45%). Although the etiology of low back pain is multifactorial, changing anatomy and biomechanics after lower extremity amputation and maintaining daily activities are often associated with the development of low back pain. Postural imbalance, which is one of the musculoskeletal disorders of the spine that contributes to low back pain, is considered to cause additional load on the spinal structures.
