Transverse rotation and longitudinal translation during prosthetic gait - a literature review

Improved technology allows for more accurate gaitanalysis to increase awareness of nonoptimized prosthetic gaitpatterns and for the manufacture of sophisticated prostheticcomponents to improve nonoptimized gait patterns. However,prescriptions are often based on intuition rather than rigorousresearch findings for evidence-based practice. The number ofstudies found in the literature that are based on prostheticresearch regarding transverse rotation and longitudinal translationis small when compared to topics regarding other types ofmovements. Some design criteria for prosthetic componentsdescribed in those studies that permit transverse rotation andlongitudinal translation can be found in current designs. However,little research has been conducted to establish their effectivenesson the gait parameters and residual limb. Thisliterature review is an investigation into these motions betweenthe socket and the prosthetic foot, with particular reference togait characteristics and prosthetic design criteria
