• Description:
  Low back pain (LBP) represents a significant secondary disability among persons with lower-limb amputation. Substantial biomechanical evidence suggests altered and asymmetric movements and muscular control strategies that could alter the mechanics of the spine during amputee gait and locomotion. Spine biomechanics (e.g., loading and stability) are largely influenced by passive mechanical properties of the spine and surrounding trunk musculature. Viscoelastic tissues of the passive spine can develop altered mechanical properties in response to changing loading patterns, rates, and magnitudes. Alterations in amputee gait and locomotion could therefore lead to musculoskeletal imbalances, contributing to further reductions in mobility and causing pain. The goal of the present study was to quantify alterations and/or asymmetries in passive trunk stiffness among unilateral lower-limb amputees (LLAs), using multi-directional trunk perturbations.
