Evaluation of hip transfemoral amputees during isometric contraction in isokinetic dynamometer

The transfemoral amputation leads to a series of changes in functional biomechanics body that can interfere with daily life of the amputee can generate patterns of posture and gait to compensate for the loss of the limb. This study aims to evaluate and compare the responses of hip muscle during isometric transfemoral amputees, using an isokinetic dynamometer. The study included four volunteers, two amputees and two non-amputees. Evaluation was performed using an isokinetic dynamometer in isometric angles of 30 degrees and 60 with duration of 10 seconds. Each series had a total of six repetitions, counting three pushups and three extensions and an interval of 20 seconds for each repetition. It is observed that the amputated limb has a lower peak torque compared to the non-amputee, in flexion and extension of the hip 30 and 60 degrees. Because amputation, individuals have less muscle strength hip, which may impair daily activities such as walking, sitting and standing, up and down stairs.
