Brief summary
The aim of this study was to analyze the angular variables of the paretic lower limb and the spatial-temporal characteristics of overground and treadmill walking at different time intervals. A total of 17 individuals with chronic hemiparesis who walked on a treadmill took part in the study. After the first 5 minutes of treadmill walking there was a 3.8%increase in cadence, 26.8% in knee angle at initial contact, 9.7% and 14.3% in hip and knee amplitude respectively and a 5% decrease in stride length, 4,9% in paretic limb step time, 61.4% in maximum stance extension and 24% in maximum ankle dorsiflexion in the stance phase compared to overground walking. After 15 minutes of treadmill walking, cadence, knee amplitude, stride length, paretic limb step time and maximum dorsiflexion continued to differ from the overground condition, with increases of 3.6% and 14% and a decrease of 5%, 6.1% and 27.3%, respectively. Subjects with hemiparesis showed equivalence in most of the spatial-temporal and angular variables during overground walking and after 15 minutes of treadmill walking, suggesting that continuous exposure to a treadmill allowed for task repetition and approximation to the overground gait pattern.
Interventions
Evaluation of kinematic of the hemiparetic lower limb and apatial-temporal data of hemiparetic gait overground and on the treadmill with the same speed. The overground walking data was obtained first of all with patients walking on a 8-m long walkway. Then was assessed the treadmill walking during 15 minutes, wich was subdivided into three 5-minute collections. A three-minute rest period was allowed between each collection. The images on the treadmill condition were captured at the 4th minute of
