Gait analysis of patients undergoing knee endoprosthesis: functional differences between tibia and femur resections.

With the improvement in survival of patients undergoing knee reconstructive surgeries, the functional parameter became widely studied heading optimize and minimize motor sequelae. In patients undergoing knee endoprosthesis, proximal tibial or distal femoral resections affect the functioning of the knee extensor mechanism, with possible repercussions on gait. Seventeen patients were selected, divided into two groups, undergoing distal femoral or proximal tibial resection, and gait analysis examination was performed.

Sydenham's chorea: clinical observations from a Brazilian movement disorder clinic.

We retrospectively evaluated the clinical and epidemiological characteristics of 100 patients suffering from Sydenham's chorea (SC). Our analysis revealed a recent, progressive decline in the number of new cases. Onset of SC was frequently reported between 7 and 12 years of age, being more frequent in females.
