Brief summary
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.
Interventions
DEVICENeuromuscular Activity Assessment
K-Pull dynamometer is an assessment tool used to quantify muscle strength. It uses traction through a non-elastic strap to facilitate isometric contractions. K-Myo (non-invasive EMG sensor) is an assessment tool used to detect muscle activation and tracking patient's improvement.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Muscle Strength | Through study completion, an average of 5 months | Average Peak Force refers to the average highest force output recorded during isometric contractions and represents the maximal strength generated by the muscle group being assessed (e.g., hip or knee flexors and extensors). Unit of Measure: Newton (N) |
| Average Muscle Activation | Through study completion, an average of 5 months | Average activation in the context of surface electromyography refers to the mean level of electrical activity detected from muscle fibers over a specific period. Unit of Measure: millivolt (mV) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Muscle Tone | Through study completion, an average of 5 months | Evaluated using the Modified Ashworth Scale. Unit of Measure: Scoring Options (0-4) // (higher scores - worse outcome) |
