Participants
We included 27 patients with transfemoral amputation (group A) and 33 asymptomatic subjects (control group) in this study. Patients’ mean age was 50.9 years (range, 28–73y). None used an assistive device during gait. Each patient’s prosthetic fitting and medical follow-up were done at the Centre d’Etudes et de Recherche pour l’Appareillage des Handicapés (CERAH). Residual limb length was measured by a physician between the anterosuperior iliac spine of the pelvis and the extremity of the
Comparison Between Groups
Figure 2 highlights the specific patterns of the pelvic motion of transfemoral amputees (group A). The 3 graphs show the comparison between subjects with and without amputation. The curves represent the evolution of pelvic angular position in the 3 planes of space during 1 gait cycle of a lower limb. On each graph, corridors (mean curve ±1 SD) are drawn. For asymptomatic subjects, we checked that curves are the same for gait cycles of right and left limbs. We chose to represent the mean curves
Discussion
This study sought to identify kinematic characteristics of upper-body motion for transfemoral amputees. Particularly, 1 purpose was to investigate simultaneously the relationships between the pelvic and the scapular girdles in the transverse plane and the torque transmitted through the lower limbs to the ground. To achieve this goal, the present work relied on a population of 27 transfemoral amputees and 33 asymptomatic subjects.
The first hypothesis was that the pelvis and the thorax exhibit
Conclusions
This study highlights the main characteristics of upper-body kinematics during the gait of people with transfemoral amputation. The analysis was conducted on a sample of 27 amputees and 33 asymptomatic subjects, which implies a good reliability of the results.
The conclusions that can be drawn concerning amputees compared with nonamputees are as follows: (1) the pelvis is globally less stable for transfemoral amputees, particularly in the sagittal plane; (2) pelvic tilt patterns are opposite;
