Effect on Gait Pattern During Robot Assisted Gait Training (RAGT) of End-effector Type in Burn Patients

Обзор

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.

Подробное описание

Patients with burn injuries to the lower extremities experience gait dysfunctions due to pain or joint contractures, and gait asymmetry occurs due to complications on the affected side. The persisting gait asymmetry placed these patients at risk for potential negative consequences, such as loss of bone mineral density of the affected side, overuse injury on the unaffected side due to compensatory actions, compromised postural control, and gait inefficiencies. Early gait training through physical therapy is a pivotal strategy for enhancing patients' quality of life, functional outcomes and mitigating burn-related complications. The conventional physical therapy is instrumental in fostering an increased range of motion (ROM) and mitigating contractures following burns or skin grafts. Physical therapy centers on patients' positioning, ROM, muscles strength, endurance, balance, coordination, and respiratory rehabilitation.Previous studies using end-effector type RAGT for patients with gait disturbances have demonstrated that RAGT combined with conventional physiotherapy could significantly improved walking speed, gait performance, and motor power . 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).

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 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.

Вмешательства

• Другое robot assisted gait training
  Morning Walk® is a new end-effector type robot developed by Hyundai Heavy Industries and Taeha Mechatronics for lower limb rehabilitation in the patients with gait disturbance.The RAGT group received RAGT with robot training for 30 minutes and conventional physiotherapy for 30 minutes per session.
• Другое conventional gait training
  The control group received conventional physiotherapy for 60 minutes per session. Conventional physiotherapy consisted of 30 minutes of therapist-assisted gait and balance training and 30 minutes of strengthening exercises. The both group patients received five training sessions per week for 8 weeks (a total of 40 sessions).
