Kinetic and Kinematic Analysis of Gait in a Patient with Transtibial Amputation: A Case Study

Transtibial amputation involves the loss of the ankle joint, distal tibia, and fibula, while preserving the knee joint. For this type of amputation, a prosthesis is required to replace the missing limb for the patient to continue their daily activities. However, some patients experience poor prosthetic adaptation, leading to gait abnormalities. A case study was conducted on a patient with left transtibial amputation to evaluate the kinetics and kinematics using baropodometry, accelerometry, and electromyography, aiming to identify potential anomalies experienced by the patient during short walking periods. Static baropodometry analysis indicated that the patient had a greater distribution of body weight on the forefoot, resulting in a forward body displacement and instability. The overall symmetry index was below normal values, indicating differences in gait between the left and right foot. Additionally, the muscle coactivation index was above normal values, indicating excessive muscle contraction and consequently poor muscle coordination.
