Robot-assisted gait training (RAGT) improves the gait ability of children with cerebral palsy, and can provide treatment plans and guidelines through changed records of various gait variables. There is a lack of concrete explanations or arguments for gait speed, weight support ratio, support force, joint angle, etc. that can be set in the RAGT system, and intervention intensity for an appropriate intervention program has not been presented. Therefore, in this study, we would like to suggest clinically effective interventions for children with cerebral palsy in the second stage of the gross motor function classification system (GMFCS) by identifying gait variables according to differences in gait speed during RAGT.

Inclusion Criteria:

• Patients 4-12 years old diagnosed with cerebral palsy
• Children who have not received botulinum toxin treatment or surgery within 3 months
• Children in stage 2 of the gross motor function system
• Children who can express pain, fear, or discomfort on their own

Exclusion Criteria:

• Severe lower extremity contracture and fracture
• Bone instability
• Osteoporosis
• Severe bones grow disproportionately
• Unhealed skin lesions on the lower extremities (thromboembolic disease)
• Thromboembolic disease
• Cardiovascular instability
• Mild scoliosis with a Cobb's angle of more than 20 degrees

I plan to decide after the study is over.
