Clinical trials

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.

This study aimed to investigate gait pattern and muscles power improvement of patient with gait disturbance caused by burns after end-effector type robot (Morning Walk®)-assited gait training (RAGT). This study randomly assigned 36 patients to one of two group : 30 minutes of Morning Walk® training with 30 minutes conventional physiotherapy (RAGT group) or 60 minutes of conventional physiotherapy (CON group). Five training sessions per week were given for 8 weeks. The primary outcomes were gait performance and muscles powers, which were assessed by the functional ambulation category (FAC) and the manual muscles test (MMT), respectively. The secondary outcomes included 6-minute walking test (6MWT), gait kinematic and spatiotemporal gait parameters. The results of this study is anticipated that the patients with gait disturbance receiving the RAGT might improve greater in gait performance and normal gait patterns that those trained with conventional physiotherapy.

Hands are the most frequent burn injury sites. Appropriate rehabilitation is essential to ensure good functional recovery. The aim of this study was to investigate the effects of EMG driven robotic rehabilitation on hand functions and skin characteristics of patients with nerve damage caused by burns. A randomized controlled, single blind trial recruited the patients with hand dysfunction after burn injury. The participants were randomly allocated to experimental group (EG) and control group (CG) for 5 days a week and totally 60 sessions for 12 weeks. The EG received robotic assisted hand training with the EMG-driven exoskeleton hand robot (Hand of Hope®.Rehab-Robotics Company) and conventional occupational therapy. The CG performed conventional occupational therapy, including hand range of motion (ROM) exercises and hand functional training twice a day for 12 weeks. Outcome measures were as follows: 10-point visual analog scale for pain, Jebsen-Taylor hand function test, grip strength, Purdue Pegboard test, joint ROMs, ultrasound measurement of scar thickness, and skin characteristics before and immediately after 12 weeks of treatment. There is still no established protocol for burn injury rehabilitation. The aim of this study was to investigate the effects of EMG driven robotic rehabilitation on hand functions and skin characteristics of patients with nerve damage and scarring caused by burns.

Joint contractures and nerve injuries are common after hand burns. Extracorporeal shock wave therapy (ESWT) is effective not only for the regeneration of various tissues, including scar tissues, but also for reducing pain and pruritus in patients with burns. Researchers have attempted to explore the effects of ESWT on hand dysfunction caused by nerve injury following burns. The investigators planned to evaluate the effects of ESWT (compared to sham stimulation) on hands with nerve injury and hypertrophic scars and thereby on hand function. The ESWT parameters were as follows: energy flux density, 0.05-0.30 mJ/mm2; frequency, 4 Hz; 1000 to 2000 impulses per treatment; and 12 treatments, one/week for 12 weeks. Outcome measures were as follows: 10-point visual analog scale for pain, Jebsen-Taylor hand function test, grip strength, Purdue Pegboard test, ultrasound measurement of scar thickness, and skin characteristics before and immediately after 12 weeks of treatment.
