Resumo(s)
The trunk and pelvis play crucial roles in gait dynamics. Post-stroke disabilities often limit gait function. Studying their postural orientation in healthy and post-stroke individuals can enhance rehabilitation strategies. Examine the postural orientation of the trunk and pélvis in the sagital plane during the initial contact to midstance phase of gait in post-stroke individuals compared to healthy individuals, identifying asymmetries within each group. A cross-sectional study with 16 participants. Kinematic data were gathered using a Qualysis® motion capture system and force platforms. Data analysis was performed with SPSS, using the Mann-Whitney, Fisher and Wilcoxon tests. The posyt-stroke group showed higher anterior pelvic tilt at initial contact of the ipsilesional limb, increased pelvic range of motion when the contralesional limb was in support, and greater asymmetry. The stroke group demonstrated significantly greater lumbar asymmetry at initial contact and diferences in range of motion between goups. The distance between T2 and T7 revealed no diferences between groups. Post-stroke group individuals exhibit increased anterior pelvic tilt and pelvic motion range during gait compared to healthy individuals. They also show greater asymmetry in pelvic and lumbar angles.
