The Effect of a Ankle Assist Robot on Gait Function and Cardiopulmonary Metabolic Efficiency in Stroke Patients

Samsung Medical Center45 enrolled

Overview

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)

Interventions

Ankle Assist RobotDEVICE

1. overground walking in three conditions (with robot-torque on/with robot-torque off/without robot). During overground walking, gait function was measured using motion analysis, sEMG, and force plate 2. treadmill waking in three conditions (with robot-torque on/with robot-torque off/without robot). During treadmill walking, the metabolic energy expenditure was measured using a portable cardiopulmonary metabolic system (Cosmed K4b², Rome, Italy).

Outcomes

Primary Outcomes

Change on gait speed in different three conditions

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.

Time frame: 20minutes

Secondary Outcomes

Change on gait function in different three conditions (kinematic)

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.

Time frame: 20minutes

Change on gait function in different three conditions (kinetic)

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.

Time frame: 20minutes

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

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.

Time frame: 20minutes

Change on metabolic energy expenditure in different three conditions

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).

Time frame: 1 hour
