چکیده
[Purpose] The purpose of this study was to compare kinematic data regarding the head, trunk, and pelvis strategies used by individuals with hemiplegia when crossing over obstacles of different heights. [Subjects and Methods] Nine adults with hemiplegia from stroke (7 males and 2 females) participated in this study. A motion analysis system with six infrared cameras was used to measure the kinematic data of the head, trunk, and pelvis while the subjects crossed over obstacles of different heights. Repeated measures ANOVA analysis was performed to compare the resulting kinematic data. [Results] An increase in the magnitude of the kinematic data of the head, trunk, and pelvis of the hemiparetic stroke patients was observed when the height of the obstacles, which they crossed over, increased. [Conclusion] This study described the kinematic strategies, with regard to the head, trunk, and pelvis, used by hemiplegic patients crossing over obstacles of different heights. The results indicate that these kinematic strategies primarily change when the obstacle height was 20% of the height of the subjects.

Key function for obstacle crossing in hemiplegic persons with varied degrees of spasticity
[Purpose] To evaluate various key functions related to obstacle crossing motions in hemiplegic people based on the paralysis degree. [Subjects and Methods] Thirty-seven patients with maintenance-stage hemiplegia who could independently ambulate outdoors were included. Subjects' crossing movements were measured using obstacles with heights of 10%, 20%, and 30% of the trochanter length. The relat...

متن کاملObstacle crossing in 7-9-year-old children with Down syndrome.
This study aimed to investigate obstacle crossing in 7-9-year-old children with Down syndrome (DS). Fifteen children with DS, age- and gender-matched with 15 typically developing (TD) children, were recruited to walk and cross obstacles with heights of 10%, 20% and 30% of their leg lengths. End-point and kinematic variables of obstacle crossing were obtained using a three-dimensional motion ana...
متن کاملUnderstanding inconsistent step-length asymmetries across hemiplegic stroke patients: impairments and compensatory gait.
BACKGROUND In hemiplegic gait, step length typically differs in magnitude between paretic and nonparetic sides. However, the direction of step-length asymmetry varies across stroke patients. OBJECTIVE The study sought to understand directional variations in step-length asymmetry in terms of asymmetries in forward foot placement relative to the trunk and trunk progression. METHODS A total of...
متن کاملKinematic Analysis of the Upper Limb Motor Strategies in Stroke Patients as a Tool towards Advanced Neurorehabilitation Strategies: A Preliminary Study
Advanced rehabilitation strategies of the upper limb in stroke patients focus on the recovery of the most important daily activities. In this study we analyzed quantitatively and qualitatively the motor strategies employed by stroke patients when reaching and drinking from a glass. We enrolled 6 hemiparetic poststroke patients and 6 healthy subjects. Motion analysis of the task proposed (reachi...
