  • Alignment of a prosthesis is defined as the position of the socket relative to the foot and any other intermediate components. During dynamic alignment the prosthetist, using subjective judgment and feed-back from the patient, aims to achieve the most suitable limb configuration for the best function and comfort. Until recently it was generally believed that a given patient could only be satisfied with a unique "optimum" alignment. Previous work carried out at the Bioengineering Unit, University of Strathclyde showed that several alignment configurations can be made to be equally acceptable to both the amputee and the prosthetist. The purpose of this study reported in this thesis was to investigate the effect of alignment variation on amputee gait. Ten active below-knee and above-knee amputees were dynamically aligned by three prosthetists several times. Markers were positioned on the defined locations on the prosthetic and sound side, and the body. Kinematic data were acquired using three cine cameras orthogonally arranged. Using a computer program from the acquired data stick diagrams, angle-time diagrams, angle-angle diagrams and temporal parameters were derived. Analysis of the results showed that various alignment configurations that were acceptable to the patient and the prosthetist resulted in appreciable variations in the gait patterns.
