How many neural input signals can be found in a large number of muscles during human locomotion?
4 - 5
motor neuron inputs
sensory inputs
reflex inputs
CPGs inputs
cerebellar inputs
What are the mechanisms that the brain uses to modulate muscle force?
What is a motor nucleus?
What is the RMS? what is its role?
What are some possible neuromuscular interfacing approaches?
What is a motor unit?
What is the sliding filament theory about?
What is EMG?
How can a surface EMG be best described?
What is Henneman´s size principle about?
what is the relationship between the size of the motor unit and the force it produces?
How can we extract individual motor unit from HD-sEMG signals?
What does Factor Analysis do? What is it for?
Why do we apply lowpass filters to the EMG signals?
During strength training, which effects can be observed?
what is active force? passive force?
What is the correlation between the MUAP amplitudes and MU recruitment thresholds within all MUs recruited in an isometric contraction? according to Henneman´s size principle
What is the neuromechanical delay?
What is the relationship between the neuromechanical delay and the rate of force development?
What are efferent and afferent impulses?
What is STA? What is it for?
What is the rate of force development?
What are the architectural or mechanical features affect muscle force production?
How can we determine the recruitment threshold of a MU?
What is a spinal reflex?
What does the AP shape of each MU look like?
What is the innervation number? How is it for human muscles?
What is the sarcomere structure?
What is the difference between fast and slow-twitch muscle fibers?
What can significantly influence the MUAP amplitude extracted from sEMG?
