Which level of the GMFCS represents the most severe involvement in a child with CP?

The Gross Motor Function Classification System (GMFCS) is used to describe the gross motor function of children with cerebral palsy (CP). It classifies individuals based on their mobility and the level of support they require.

Level 5 represents the most severe involvement among the classifications. Children at this level experience significant limitations in voluntary movements, requiring extensive support for all aspects of mobility. They are unable to maintain head and trunk control and rely heavily on others for assistance, indicating profound difficulties in movement and postural control.

In contrast, the lower levels, such as Levels 1 to 4, reflect varying degrees of mobility capabilities, from children who are fully independent in gross motor function (Level 1) to those who require some assistance but can still walk (Level 3 or Level 4). Therefore, Level 5 distinctly characterizes the highest severity of motor impairment in individuals with CP, highlighting the critical need for substantial assistance and adaptive measures in daily activities.
