The Effects of Gait Performance and Brain Activity After Robot-assisted Gait Training (RAGT) On Patients With Lower Extremity Thermal Injury
A study testing robot assited gati training and conventional traiing in people with Gait Disorder, Sensorimotor, run by Hangang Sacred Heart Hospital.
Trial summary
Gait enables individuals to move forward and is considered a natural skill. Gait disturbances are very common in patients with burn injury. Major causes of gait disturbances are pain and joint contractures. Recent studies focused on the application of robot-assisted gait training (RAGT) for improving gait functions.

About this study
Official title: The Effects of Gait Performance and Brain Activity After Robot-assisted Gait Training (RAGT) On Patients With Lower Extremity Thermal Injury : a Prospective, Randomized, Single-blinded Study
Gait enables individuals to move forward and is considered a natural skill. Gait disturbances are very common in patients with burn injury. Major causes of gait disturbances are pain and joint contractures. Recent studies focused on the application of robot-assisted gait training (RAGT) for improving gait functions. This study aimed to elucidate the efficacy and investigate the mechanism of motor recovery after RAGT on patients with lower extremity burn. To investigate the clinical effects, the investigators compare the results of RAGT group to the results of matched conventional (CON) rehabilitation group.This single-blinded, randomized, controlled trial involved 40 patients with lower extremity burns. Patients were randomized into a RAGT or a CON group. SUBAR® (CRETEM, Korea) is a exoskeletal-robot with a footplate that assists patients to perform gait motions. RAGT enables training of automatically programmed normal gait pattern. Patients underwent 30 min of RAGT using SUBAR® and conventional exercise rehabilitation each for 30 min once a day for 5 days a week for 8 weeks. The CON group focused on gait training such as active range of motion (ROM) exercise, weight bearing training, manual lymphatic drainage, and hypertrophic scar care for 60 min once a day for 5 days a week for 8 weeks.A wearable functional near-infrared spectroscopy (fNIRS) device has been developed for studying cortical hemodynamics. Changes in cortical activity has not previously been documented in patients with burn injury. The primary outcome was the prefrontal cortical activity in the both groups. The walking-related cortical activity using an fNIRS device before and after 8 weeks training were measured. To evaluate functional recovery, functional ambulation category (FAC) scores and 6-minute walking test (6MWT) distances were measured. Numeric rating scale (NRS) was used to rate the degree of subjective pain during gait movement: 0 points were assigned when no pain was noted, and unbearable pain was assigned 10 points.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
robot assited gati trainingOther
SUBAR® (CRETEM, Korea) is a exoskeletal-robot with a footplate that assists gait movements. The patient's thigh length and lower leg length were measured before training, so that the SUBAR® can be adjusted to patient's size to ensure accurate training. During training, the therapist facilitated the treatment and stood by the patients' side to adjust the direction and speed. RAGT is programmed automatically, and it can be performed regularly over a long period. The patients received 30 min of robot-assisted training using SUBAR® once a day for 5 days a week for 8 weeks. Each training session lasted up to 40 min.
conventional traiingOther
Patients also received conventional exercise rehabilitation with the same duration and frequency. Conventional rehabilitation therapy, which consisted of active assistive knee exercises, knee stretching, patellar mobilization exercises, and quadriceps setting exercises, was performed every day throughout the rehabilitation period.
| Study group | Role | What they receive |
|---|---|---|
| robot assisted gait training | Experimental | RAGT enables training of automatically programmed normal gait pattern. Patients underwent 30 min of RAGT using SUBAR® and conventional exercise rehabilitation each for 30 min once a day for 5 days a week for 8 weeks. Receives: Other: robot assited gati training |
| conventioanl training | Active comparator | The conventional training group focused on gait training such as active range of motion (ROM) exercise, weight bearing training, manual lymphatic drainage, and hypertrophic scar care for 60 min once a day for 5 days a week for 8 weeks. Receives: Other: conventional traiing |
What is being measured
The primary outcome is the main question the study is designed to answer.
near infrared spectroscopy
The rest period before gait period served as a baseline reference for osyhemoglobin of PFC perfusion. Cortical activity was measured by evaluating relative changes in oxyhemoglobin level and deoxyhemoglobin level.
Measured: 8 weeks
Secondary outcomes (3)
numeric rating scale (NRS)
rate the degree of subjective pain during gait movement: 0 points were assigned when no pain was noted, and unbearable pain was assigned 10 points.
Measured: 8 weeks
functional ambulatory category
FAC was evaluated based on six scales. Scale 0 means that the patient cannot walk or can only walk with assistance of two people. Scale 5 means that the patient can walk independently.
Measured: 8 weeks
6 minutes walking test
Patients were instructed to walk as far as possible in 6 min
Measured: 8 weeks

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 18 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Sung Rakyum (82-2-2639-5900, sung6652@hallym.or.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
near infrared spectroscopy (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05988905, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2023.
