Walking Training With Partial Body Weight Support on Static and Dynamic Surfaces in Stroke Survivers

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is evaluate the effects of walking training with partial body weight support on static (floor) and dynamic (treadmill) surfaces in individuals with hemiparesis due to stroke. For this purpose, two training protocols will be employed in three experimental groups: G1 will do the walking training with partial body weight support on static surfaces and G2 will do the walking training with partial body weight support on dynamic surfaces

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Static surface<br>The subjects will do the walking training with partial body weight support on static surface. The will be submitted to three weekly training sessions of approximately 45 minutes each , for six weeks , totaling 18 sessions | Procedure: Static surface<br>* During all session time the subject will walk on the floor with partial body weight support. This protocol will be repeated in all sessions.<br>* Other names: floor walking training;|
| Active Comparator: dynamic surface<br>The subjects will do the walking training with partial body weight support on dynamic surface. The will be submitted to three weekly training sessions of approximately 45 minutes each , for six weeks , totaling 18 sessions | Procedure: Dynamic surface<br>* During all session time the subject will walk on the treadmill with partial body weight support. This protocol will be repeated in all sessions.<br>* Other names: Treadmill Training;|

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from Baseline in the gait velocity | Speed at which subjects walked measured by the 10 meters test | Baseline, immediately after and six weeks after training cessation. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Distribution of body weight | Body weight Distribution measured while subjects are in a static position on two force platforms. | Baseline, immediately after and six weeks after training cessation. | 
| Functional independence | a score was assigned for each everyday activity, according to the amount of assistance required to perform it. Measured by a clinical scale (Functional Independence Measure Scale. | Baseline, immediately after and six weeks after training cessation. | 
| Lower limb recovery | Measured by a clinical scale (Fulgy Meyer). | Baseline, immediately after and six weeks after training cessation. | 
| Endurance | Measured by the 6 minutes walking test | Baseline, immediately after and six weeks after training cessation. |
