Lower Extremity Dynamometry Assessment in Neurotypical Children

The purpose of this study is to assess the reliability (intra-rater and inter-rater) and criterion validity (using a Cybex isokinetic dynamometer as the reference) of the K-Pull (traction) dynamometer for evaluating lower limb function in children with neurotypical development.

Analysis of Neuromodulation as a Complementary Treatment to Evidence-based Clinical Intervention in Subjects With Musculoskeletal Pathology of the Lower Limb: a Double-blind Randomized Clinical Trial

This project aims to analyze the use of neuromodulation within a treatment protocol for musculoskeletal conditions of the lower limb, as well as to determine the difference between two and three sessions per week. Study participants will be divided into four intervention groups: the first will receive two sessions per week for a period of six months, while the second will receive three sessions per week for the same period. The treatment protocol will consist of therapeutic physical exercise focused on the muscles and joints of the lower limb, stretching of the involved muscles, and neuromodulation of the nerve root of the lumbosacral plexus, which innervates the affected structures. The third and fourth intervention groups will receive the same treatment as mentioned above, but without neuromodulation. The third group will receive three sessions per week, while the second group will receive two sessions per week. Two different types of measurement variables will be used: objective variables will be used to measure range of motion and muscle strength. Subjective variables will also be used through validated questionnaires, covering physical activity, health-related quality of life, lower limb function, and a visual analog scale for pain perception.

Muscle Activity of the Gastrocnemius and Soleus Muscles by Surface Electromyography.

This cross-sectional, comparative study aims to evaluate and compare the surface electromyographic (sEMG) activity of the gastrocnemius (medial and lateral) and soleus muscles during static and dynamic contraction tasks. Participants will perform three tests-resting state, isometric, concentric, and eccentric contraction, and dynamic gait-with bilateral measurements. A subgroup analysis will examine muscle activity variations based on foot posture, using the Foot Posture Index (FPI). The study uses the validated mDurance® sEMG system to obtain objective data under controlled lab conditions. The findings will enhance understanding of the functional role of each muscle and could inform rehabilitation and injury prevention strategies.
