Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Walking is considered one of the most important activities in daily life, as it is essential for activities of daily living and social participation. Children with Gross Motor Function Classification System (GMFCS) levels I, II, and III show potential for walking, and around 75% of CP children are ambulatory. However, abnormalities in neural control and muscle weakness contribute to several gait characteristics such as slow velocity, decreased stride length, increased stance phase percentage, and increased peak ankle dorsiflexion and knee flexion, and peak hip extension moments. Consequently, this gait pattern contributes to postural instability and increased fall risk in children with CP, among others.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study design is a two-arm randomized clinical trial, single-center and single-blind (evaluators). The sample will be recruited at the Hospital General de Vic, and the study will be conducted at the Universitat de Vic - Universitat Central de Catalunya (UVic-UCC).

Study Groups

Treadmill training
The treadmill training would be 10 sessions over 2 weeks with 30 minutes for each session (5-min warm-up; 20 min gait training; 5-min cool-down). During the sessions, treadmill speed will be maintained at 60 to 80% of the maximum speed established on an exertion test. The child will walk at 60% maximum speed in the first and final five minutes and 80% in the middle 20 minutes.
Treadmill training
The RAM870A of the Medisoft treadmill will be used. Two treadmill training sessions will be held before the onset of the intervention to familiarize the children with the equipment. During these two sessions, the treadmill training and speed will be set according to the following procedures: the ground walking speed of each child will be determined through the baseline 6MWT, then the training velocity will be set at 50% of the maximum ground speed established during the 6MWT and increased gradually based on the tolerance of each child (i.e., no complaint of fatigue, heart rate not exceeding 70% of the maximum heart rate, and a lack of gait shuffling, buckling or dragging steps more than 5 seconds during walking).
Virtual reality
Infants in the TTVR group will perform gait training on the treadmill simultaneously with virtual reality.
Treadmill training with virtual reality
The virtual environment will be composed of obstacles, different paths, and narrow and deviated corridors. Walking through this environment will require the infant to coordinate walking behaviour and adjust the length, height, and width of steps to negotiate the obstacles on the television screen placed at the infant's eye level in front of the treadmill. The speed, orientation, size, frequency of appearance, and shape of the obstacles will be manipulated according to individual performance following a standardized protocol. The virtual system will provide visual and auditory feedback on the success or failure of the activity to enhance motor learning. In addition, the characteristics of the environment (e.g., visibility, configuration, and distractions) will be adjusted to increase the complexity of the training.
