The aim of this study was to quantify the motor adaptations in the
frontal plane made by unilateral transtibial amputees (UTAs),
with special regard
to: (1) abduction/adduction moment at the hip and knee valgus moment in the
frontal plane; (2) pelvic and thorax obliquity; and (3) stride length and gait
speed. METHODS: 15 Males with unilateral transtibial amputation comprised the
subject group and 15 non-disabled individuals served as control group. Gait
analysis was performed using the VICON MOTION SYSTEM((R)) (Oxford Metrics,
Oxford, UK). RESULTS: In this study, UTAs walked with a reduced hip abductor
moment during the stance phase. At the knee joint, the valgus moment was reduced
in the prosthetic limb compared to the sound and the control limb. The thorax
range of motion in the frontal plane was increased on the prosthetic side,
compared with the non amputee subjects. CONCLUSION: Our findings suggest that
unilateral transtibial amputation patients walk with different motor control
strategies in the frontal plane compared with the non-disabled subjects. These
results suggest the need for specific training for this group of UTAs, focusing
on exercises to stabilize and strengthen the proximal muscles as well as
practicing balance and coordination in the coronal plane.
