NCT02650440

Brief Summary

The objective of this study is to compare the effects of novel versus standard locomotor training using a robotic gait orthosis (LT-RGO) after stroke. The hypothesis is that the novel LT-RGO protocol, by establishing a progressive decrease in gait velocity and guidance force, may facilitate greater motor recovery compared to the use of a standard protocol.

Outcome Measures

Primary Outcomes (1)

  • Functional Ambulation Scale (FAC)

    The Functional Ambulation Scale (FAC) assesses an individual's independence during gait and follows a six-level scale: 0 - Patient can not walk or ask for help from two or more people; 1 - Patient requires continuous support from a person who assists with weight and balance; 2 - Patient needs continuous or intermittent support from a person to help with balance and coordination; 3 - Patient required for a person without physical contact; 4 - Patient can walk independently on the floor, but requires help on stairs and ramps; 5 - Patient can walk independently. This study compared the gait independence by the FAC between the two Arms, after intervention as compared to baseline.

Study Arms (2)

Novel Protocol

EXPERIMENTAL

Progressive decrease of speed and guidance force on robotic gait training. Initial speed is 1.4 km/h and final speed is 1.0 km/h.

Procedure: Novel Protocol

Standard Protocol

EXPERIMENTAL

Progressive increase of speed and decrease of guidance force on robotic gait training. Initial speed is 1.4 km/h and final speed is 1.9 km/h.

Procedure: Standard Protocol

Interventions

All subjects performed robot-assissted LT-BWST 5 times a week for 6 weeks (30 minutes of training and 15 minutes of setup). Novel (discrete) robot-assisted LT-BWST used progressive decrease in speed. Both groups started the robot-assisted LT-BWST at the same speed of 1.4km/h. The body weight support started approximately at 40% of body weight for both groups and rapidly decreased each week. The guidance force was also progressively decreased for both groups so that the exoskeleton provided the least possible assistance to the subject.

Novel Protocol

All subjects performed robot-assissted LT-BWST 5 times a week for 6 weeks (30 minutes of training and 15 minutes of setup). Standard (rhythmic) robot-assisted LT-BWST used progressively increased speed each week. Both groups started the robot-assisted LT-BWST at the same speed of 1.4km/h. The body weight support started approximately at 40% of body weight for both groups and rapidly decreased each week. The guidance force was also progressively decreased for both groups so that the exoskeleton provided the least possible assistance to the subject
