Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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 each collection.
Intervention code [1] 256391 0
Not applicable
Comparator / control treatment
All participants take part in the overground and treadmill walking. The overground walking data act as the comparator treatment of the results obtained at the three 5-minutes collections on the treadmill walking.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 258338 0
There were alterations in some of the spatio-temporal characteristics on the treadmill walking compared to overground walking registered by the Motion Capture System (Qualisys AB). Cadence increased 3,8%, stride lenght and paretic limb step time decreased 5% and 4,9% respectively.
Timepoint [1] 258338 0
After 5 minutes of treadmill walking.
Primary outcome [2] 258339 0
There were alterations in some of the Kinematic characteristics on the treadmill walking compared to overground walking registered by the Motion Capture System (Qualisys AB).There were a increase of 26.8% in knee angle at initial contact, 9.7% and 14.3% in hip and knee amplitude respectively. There were a decrease of 61.4% in maximum knee stance extension and 24% in maximum ankle dorsiflexion in the stance fase.
Timepoint [2] 258339 0
After 5 minutes of treadmill walking.
Primary outcome [3] 258340 0
Hip amplitude, knee angle at initial contact and maximum knee stance extension were not significantly altered on the treadmill walking compared to overground walking registered by the Motion Capture System (Qualisys AB).
Timepoint [3] 258340 0
After 15 minutes of treadmill walking.
Secondary outcome [1] 264056 0
There were increases of 3.6% in cadence and 14% in knee amplitude on the treadmill walking compared to overground walking registered by the Motion Capture System (Qualisys AB). There were decreases of 5% in stride lenght, 6,1% in paretic limb step time and 27,3% in maximum dorsiflexion on the treadmill walking compared to overground walking registered by the Motion Capture System (Qualisys AB).
Timepoint [1] 264056 0
After 15 minutes of treadmill walking.
