Clinical Trial Summary

Quadriceps muscle strength is a key goal to be achieved in rehabilitation protocols for a variety of musculoskeletal conditions. Both cerebral and peripheral electrical stimulations can modulate motor brain areas involved in motor functions and has the potential to optimize muscle capacity. However, their effects on quadriceps function are lacking.

This study aims to investigate the effects of transcranial direct current stimulation (tDCS) and peripheral electrical stimulation (PES) on quadriceps strength in healthy subjects.

Intervention

Device:
• Cerebral stimulation
Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation (NIBS) technique that has been investigated for the management of various health conditions. However, its ergogenic effect still has controversial results.
• Peripheral stimulation
Peripheral electrical stimulation (PES) activates a complex neural network involving a series of neurotransmitters and receptors capable of promoting segmental and extrasegmental analgesia. Moreover, recent evidence has shown that PES can activate brain motor areas such as primary motor cortex.
