Running footstrike pattern effect on lower extremity work in an individual with transtibial amputation.

Asymmetrical loading favoring the intact limb during running has been associated with increased prevalence of reported knee pain and potential risk factors of knee osteoarthritis in that limb for patients with amputation. Footstrike pattern alterations have been suggested to help alleviate some overloading of the knee, but little is known about how it affects the rest of the limb. The purpose of this case study was to evaluate the effect of footstrike pattern on the distribution of loading throughout the lower extremities during submaximal running of an individual with transtibial amputation (TTA).

Assessments of trunk postural control within a fall-prevention training program for service members with lower limb trauma and loss.

Background: Trunk postural control (TPC) is critical in maintaining balance following perturbations (i.e., avoiding falls), and impaired among persons with lower extremity trauma, contributing to elevated fall risk.

Do Gait and Functional Parameters Change After Transtibial Amputation Following Attempted Limb Preservation in a Military Population?

Background: Surgical attempts at lower limb preservation after trauma may be complicated by pain and gait disturbances, which can impact the activity level of a military service member. It is unclear how later transtibial amputation (TTA) might affect patients who elect this option after attempts at limb preservation.

Questions/purposes: The purposes of the study were to compare preamputation and postamputation (1) the numeric rating scale for pain and pain medication use; (2) self-reported activity level, Four Square Step Test (FSST) results, and assistive device use; and (3) spatiotemporal variables measured with instrumented gait analysis in individuals who elected TTA after multiple attempts at limb preservation.
