Spatio-temporal, kinematic and kinetics gait analysis in post-stroke individuals

Abstract

Objective: To analyze the spatio-temporal, kinematic and kinetic characteristics of gait in post-stroke individuals. The sample consisted of 16 individuals (10 from the Post-stroke group and 6 from the Control group). The analysis of gait variables, range of motion, moment and power of the ankle were obtained using Qualysis Track Manager®, with 10 cameras, filming a 5-meter course. Results: The Post-stroke group showed a speed approximately 50% lower than the Control group (p <0.0001). With respect to kinetics, the non-paretic side of ankle moment and power were higher than paretic side, but lower than control group. (p <0.05). In kinematics there was no intergroup difference. Conclusion: Changes in gait in the post-stroke period may have occurred due to muscle disuse on the paretic side, probably triggering the phenomenon of muscle plasticity, in which changes in the phenotypic expression of muscle fibers occur.
