The purpose of this study is to evaluate the reliability (intra-rater and inter-rater) of the K-Pull dynamometer and the K-Myo non-invasive electromyography sensor (assessing neuromuscular activity) in the evaluation of the lower limbs in children with cerebral palsy.

Specific objectives include:

• Examining differences in neuromuscular activity among children with CP classified at functional levels I to III on the GMFCS scale.
• Deriving conclusions from the correlation between electromyographic activity, muscle tone, and generated muscle strength.
• Assessing the applicability of neuromuscular activity assessment devices in clinical settings.

Inclusion Criteria:

• children with spastic type cerebral palsy (CP),
• aged between 5 and 16 years,
• classified at GMFCS levels I to III,
• voluntary motor control,
• ambulatory, with or without the use of mobility aids,
• can understand and execute verbal commands.

Exclusion Criteria:

• have previously undergone interventions that affect neuromuscular performance (such as surgery or botulinum toxin injections)
• have sustained an injury,
• demonstrate a low level of compliance.

Children with cerebral palsy, aged 5 to 16 years, classified at GMFCS levels I to III based on specific inclusion and exclusion criteria to ensure the reliability and feasibility of traction dynamometry and surface electromyography assessment.
