Research on Clinical Safety and Effectiveness of Wearable Assistive Devices With Flexible Structure for Daily Life Support of Stroke Patients
A study testing Soft Wearable Robot in people with Stroke and Hemiplegia, run by Yonsei University at 1 site in South Korea.
Trial summary
Gait independence is a critical goal for stroke patients and significantly impacts their return to society. Due to hemiplegia, stroke patients often face walking difficulties. Compensatory approaches using lower limb assistive devices have shown promise in improving independent walking. Read more about this study

About this study
Gait independence is a critical goal for stroke patients and significantly impacts their return to society. Due to hemiplegia, stroke patients often face walking difficulties. Compensatory approaches using lower limb assistive devices have shown promise in improving independent walking. Wearable assistive devices, which minimize daily life restrictions, are gaining attention globally. Despite the availability of many imported rehabilitation assistive devices, their high cost and poor fit for East Asian patients highlight the need for domestic alternatives. In light of the global interest in robotics, there is a shortage of domestic research on advanced wearable robots. This study aims to clinically test and verify the effectiveness of a flexible, wearable robotic assistive device developed by Angel Robotics for stroke patients.
Read the detailed description
The study will enroll 20 participants, providing knee and hip assistance during overground walking adaptation training. Participants will undergo an initial assessment followed by three 30-minute sessions of training with a powered hip assistive device over two weeks. Post-intervention Assessment 1 will follow this training. Then, participants will undergo three 30-minute sessions of training with a powered knee assistive device over the next two weeks, followed by Post-intervention Assessment 2. Each participant will have nine visits in total, including three functional assessments and six adaptation training sessions. The schedule for subsequent visits will be arranged during the first visit. The familiarization process will be conducted two to three times per week, adjusted for participants' convenience, with each set of three visits completed within three weeks. Trained therapists will handle the attachment and adjustment of the powered assistive devices.
Assessments will be conducted at three points: before the first training session, after the third session, and after the sixth session. Measurements will be taken under three conditions: without the assistive device, with the assistive device but without power assistance, and with the assistive device and power assistance, in random order.
This study will evaluate the following: Gait speed using the 10-meter walk test, Walking distance using the 6-minute walk test, 3D gait analysis (Human body model) assessing kinetics and kinematics, Energy consumption, including oxygen rate (VO2/ml/min per kg of body weight) and oxygen cost (oxygen rate per walking speed in m/min), Lower limb strength and motor function, assessed by the Functional Ambulatory Category (gait independence), Berg Balance Test (balance ability), and Rivermead Mobility Index (motor ability), These evaluations will help determine the effectiveness of the wearable robotic assistive device in aiding the gait of stroke patients.

This study aims to enroll 20 participants who will receive assistance in flexion and extension of the knee and hip during overground walking adaptation training. Following the initial assessment, participants will undergo three 30-minute sessions of overground walking adaptation training with a powered hip assistive device over two weeks. After completing these sessions, Post-intervention Assessment 1 will be conducted. Then, participants will undergo three 30-minute sessions of overground walking adaptation training with a powered knee assistive device over two weeks, followed by Post-intervention Assessment 2. Each participant will have a total of nine visits, including three functional assessments and six adaptation training sessions. The first visit will involve scheduling subsequent visits. The familiarization process will occur two to three times per week, adjustable for participants' convenience, with each set of three visits completed within three weeks.

What is being measured
The primary outcome is the main question the study is designed to answer.
10-meter walking test
The 10 Meter Walk Test (10MWT) is a simple and commonly used assessment to evaluate walking speed. During the test, participants are instructed to walk a distance of 10 meters. The time is measured for the middle 6 meters, allowing the first and last 2 meters for acceleration and deceleration. This approach ensures a more accurate assessment of the participant's steady-state walking speed.
