Effects of Peripheral Somatosensory Stimulation Through Mechanical Pressure on Lower Limb Muscle Strength in Stroke Survivors
Sponsor: Pedro Victor López Plaza
Summary
Somatosensory information is essential for the motor system because when the central nervous system stops receiving afferent signals, it cannot use information about the state of the affected body part to plan or adjust movement. This phenomenon is known as sensory deafferentation, and it significantly affects motor function. This principle offers an opportunity to observe changes in strength through a peripheral proprioceptive stimulus that activates the muscular system with the aim of increasing recruitment. This would justify the implementation of proprioceptive input in approaches focused on motor learning in movement disorders resulting from cortical lesions such as stroke.

Interventions
deep peripheral sensory stimulation
The proprioceptive stimulus will consist of intermittent mechanical pressure on the skin, localized at the neuromuscular motor points of the rectus femoris, vastus lateralis, and vastus medialis of the quadriceps. The tissue subjected to this precise pressure in areas of high neuromuscular innervation facilitates the stimulation of kinesthetic cortical sensitivity. The experimental group (EG) will be randomly and crosswise subdivided into two groups, so that both receive the intervention in two different modalities at two different times.
