Not Applicable
Completed
Conditions
Stroke
Gait, Hemiplegic
Interventions
Device: Ankle Assist Robot
Registration Number
NCT03767205
Lead Sponsor
Samsung Medical Center
Brief Summary

The aim of this study was to identify the assistance effect of Ankle Assist Robot v1 developed by Samsung Advanced Institute of Technology (Samsung Electronics Co, Ltd., Korea) by comparing

1. gait function during overground gait in three conditions (with robot-assist torque on/with robot-assist torque off/without robot)

2. the energy expenditure during treadmill gait in three conditions (with robot-assist torque on/with robot-assist torque off/without robot)

GroupInterventionDescription
stroke patientsAnkle Assist RobotAll participants perform overground walking and treadmill waking in three conditions (with robot-torque on/with robot-torque off/without robot).
Primary Outcome Measures
NameTimeMethod
Change on gait speed in different three conditions20minutes

All participants perform overground walking in different three conditions (with robot-torque on/with robot-torque off/without robot) to assess the change of gait speed using a motion analysis.

Secondary Outcome Measures
NameTimeMethod
Change on gait function in different three conditions (kinetic)20minutes

All participants perform overground walking in different three conditions (with robot-torque on/with robot-torque off/without robot) to assess the change of kinetic using a force plate.

Change on metabolic energy expenditure in different three conditions1 hour

All participants perform treadmill walking in different three conditions (with robot-torque on/with robot-torque off/without robot) to assess the change of metabolic energy expenditure using a portable cardiopulmonary metabolic system (Cosmed K4b², Rome, Italy).

Change on gait function in different three conditions (muscle activation)20minutes

All participants perform overground walking in different three conditions (with robot-torque on/with robot-torque off/without robot) to assess the change of muscle activation using a surface EMG.

Change on gait function in different three conditions (kinematic)20minutes

All participants perform overground walking in different three conditions (with robot-torque on/with robot-torque off/without robot) to assess the change of kinematic using a motion analysis.
