Summary

Cerebral Palsy (CP) is a complex neurodevelopmental disorder caused by early brain injury, leading to motor impairments such as muscle weakness, stiffness, and gait instability, which impact daily functioning. Gait training is crucial for improving mobility and independence in children with CP. Recently, robotic gait training (RAGT) devices, such as exoskeletons, have been explored as a rehabilitation tool. Although widely studied in adults, evidence of the effectiveness of RAGT in children with CP is limited. Preliminary studies have shown promising results in improving motor function and gait in children, yet more research is needed to validate its clinical efficacy comprehensively. This study aims to assess the impact of exoskeletal RAGT on daily activities, motor function, balance, and walking in adolescents with CP.

Detailed description

Cerebral Palsy(CP) is a complex disorder caused by brain lesions that affect muscle tone, posture, movement, and gait. It is a neurodevelopmental, non-progressive disease caused by brain injury before the age of 3(1). The damaged brain results in persistent disability throughout childhood and beyond. Cerebral Palsy is characterized by motor impairment that results in decreased muscle strength in certain muscles, causing muscle weakness, stiffness, contractures, and fatigue(2, 3). These features lead to decreased coordination between the muscles required to perform motor skills, which prevents the heel strike during gait(4), resulting in decreased motor control of body segments, decreased stride length, and increased gait instability, all of which contribute to poor gait quality(5, 6). Gait training, one of the main rehabilitation goals to improve the quality of life for children with Cerebral Palsy, aims to improve standing, walking, running, and hopping motor skills to help them live independently(7, 8). Various types of robotic gait training devices have been developed to treat children with Cerebral Palsy. They are categorized into two types, exoskeleton and end-effector, depending on their principle of operation. The exoskeleton type moves joints such as hip, knee, and ankle joints to match the gait cycle. On the other hand, the end-effector type moves the foot by moving the footplate on which the body is supported(9). Robot-assisted gait training (RAGT), an emerging area of rehabilitation, was initially developed for adults using driven gait orthoses (DGOs)(10, 11). Since the 21st century, several studies have reported that robot-assisted gait training improves walking performance in people with stroke or spinal cord injury. One systematic literature review reported that it is effective for the above conditions, but there is insufficient evidence for traumatic brain injury or Parkinson's disease(12, 13). The robotic gait training device Lokomat (Hocoma, AG, Volketswil, Switzerland) has released a pediatric version of the gait training robot(14-16) to start gait training for children around four years of age. The usability of robotic gait training has been tested in the neurorehabilitation of pediatric diseases over the past several years. It was recently found that robotic gait training is a safe intervention method for children(17, 18). However, there is currently a significant lack of evidence regarding the clinical effectiveness of robotic gait training for various pediatric patient populations. A recent study conducted at a university hospital reported improvements in gross motor function, gait speed, and endurance with reduced energy expenditure following robotic gait training (Angel-legs, ANGEL ROBOTICS Co., Ltd., Seoul, Korea) for three children with cerebral palsy (ages 9, 13, and 16). Additionally, for two children with ataxic cerebral palsy (ages 11 and 12), combining conventional intensive rehabilitation therapy with robotic gait training led to reported improvements in gross motor function, functional balance, and walking ability(20). However, there is still a lack of evidence on robotic gait training for various pediatric diseases, and no studies have been conducted to demonstrate its effectiveness through various evaluations. Therefore, we aimed to investigate the effects of exoskeleton robotic gait training on activities of daily living, gross motor function assessment, balance, and walking ability in adolescents with Cerebral Palsy.

Type	Name	Description
DEVICE	Powered Exoskeleton Gait Training	A trained medical professional will adjust the exoskeleton to fit each participant and tailor the program(sit to stand, stand to sit, standing balance and weight shift, walk in place, walk forward) according to their physical condition and specific needs. Based on each participant's walking ability, appropriate safety devices (such as crutches, canes, or a harness) will be used during the intervention.
