Kinematic modifications after surgical correction of equinovarus foot deformity in chronic hemiplegic adults

Abstract

nertia during the pivot phase. The actual pivot phase required hree specific power phases in the transverse plane (A2T, 2T, H2T), which provided rotational power to displace the oG toward the new direction. The rotational power at the nkle appears to have been a result of a counter movement uring the deceleration phase, which resulted in an absorption 1T phase prior to the generation A2T phase. The timings of he transverse power peaks suggest that rotation was coming own the kinetic chain initiated from the hip. However, it is robable that the upper body segments lead the pivot [1]. The ipsilateral crossover turn did not require increased uscular demand during the turn phase, as there was no pivot hase suggesting the turn was a result of a fall rather than by ny active means. Because there was no pivot and the foot as rooted to the ground, to complete the crossover, an H3T eneration phase externally rotated the hip/pelvis toward the ew direction.
