This study aims to examine the clinical effectiveness of gait training using wearable robots in patients with impaired gait function after burn injury. The participants were chronic patients who underwent split-thickness skin grafting or burns of more than 50% of the lower extremities and still had impaired gait dysfunction 6 months later. Eligible participants were aged over 18 years and had a Functional Ambulation Category (FAC) score of 3 or higher. Physiotherapy was performed on a one to one basis by qualified physiotherapists for 1 hour per day, 5 days a week Monday through Friday, for 12 weeks. Assessments were carried out before and immediately after the 12-week training period. Physical ability were assessed using the functional ambulatory category(FAC) scale, the 6-Minute Walk Test (6MWT), and the visual analogue scale (VAS). Spatiotemporal gait parameters-including gait speed, cadence, and step length-and sagittal joint kinematic parameters for the hip, knee, and ankle during stance and swing phases were measured during gait analysis. Pulmonary function test such as forced vital capacity (FVC), 1-s forced expiratory volume (FEV1), and carbon monoxide (DLco). The highest maximal expiratory pressure (MEP) and maximal inspiratory pressure (MIP) value were evaluated.
Regaining a mobility level post-surgery that comes close to the patient's previous mobility as a baseline is the goal. It is commonly accepted that conventional physiotherapy after burn injury has a positive impact on muscle strength, range of motion, pain or gait performance which all impact patient mobility. Wearable robots that assist walking centered on the hip joint of the lower extremities are appearing. This wearable robot is a positive effect in terms of increased energy efficiency and posture during walking. This study aims to examine the clinical effectiveness of gait training using wearable robots in patients with impaired gait function after burn injury. The participants were chronic patients who underwent split-thickness skin grafting or burns of more than 50%of the lower extremities and still had impaired gait dysfunction 6 months later. Eligible participants were aged over 18 years and had a Functional Ambulation Category (FAC) score of 3 or higher. This study excluded patients with fourth-degree burns (involving muscles, tendons, and bone injuries), severe communication disorders because of intellectual impairment and psychological problems. The specific exclusion criteria were as follows. Patients with body types that prevent them form wearing the robot, such as a height of 4.59 feet (140cm) or 5.91 feet (185cm) or more, or severe obesity with a BMI of 35 or more. Patients with heart and circulatory conditions that may affect gait training. Patients at a high risk of falling during gait training, owing to severe dizziness and having experienced a fall within the preceeding 2 month.Physiotherapy was performed on a one to one basis by qualified physiotherapists for 1 hour per day, 5 days a week Monday through Friday, for 12 weeks.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

The wearable robot (WIRobotics Inc) is a wearable robot designed to provide assistive torque and resistive torque for hip movement. It is worn around the waist and thighs and weight approximately 1.6 kg. The main body and actuation parts are not located at the hip joints and back to avoid restricting body movements and to facilitate movement even in cramped spaces. Physiotherapy was performed on a one to one basis by qualified physiotherapists for 1 hour per day, 5 days a week Monday through Friday, for 12 weeks.

functional ambulatory category
Participants were rated on a six-point scale based on the level of physical assistance required for walking, regardless of whether an assistive device was used.
Time frame: 12 weeks
6-Minute Walk Test (6MWT)
conducted according to standardized guidelines, on a 20-meter walking course. Patients were instructed to walk as far as possible in 6 min.
Time frame: 12weeks
visual analogue scale (VAS)
rate the degree of subjective pain during gait movement (0 points : when no pain was noted, and 10 points : when unbearable pain was noted).
Time frame: 12 weeks
sagittal joint kinematic parameters for the hip, knee, and ankle during stance and swing phases
the total range of motion of hip, knee, and ankle during one gait cycle
Time frame: 12 weeks

Started May 2025 (actual). Primary completion is estimated for Nov 2026, 18 months after the start.
Of 210 non-industry interventional studies with no phase under Burns, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 38. This study's planned 18 months is close to that.
Counting every sponsor, half of 239 studies reached it within 15 months; a quarter within 6 and three quarters within 38.
