BIOFEEDBACK

what is biofeedback?

informs user about physiological or bomechanical processes

what is peak amplitude

highest egg activity during muscle contraction

what is contraction latency

time it takes to reach peak amplitude

what is return latency

from peak amplitude o resting or baseline level

what is hold capacity

time during consistent EMG amplitude

what is threshold

goal level of activity set by clinician

what are the physiological effects

provides myoelectrical activity feedback to user for activity modifcation/ training

neuromuscular facilitation

inhibition

coordination

what is the neuromuscular facilitation?

combats arhtrogenic muscle inhibition (normal muscle function inhibited due to pain and swelling)

with a reduction in AMI, the muscles ability to generate force will increase

what could we use BIOFEEDBACK for?

hemiplegia

quad strengthening

headache

pelvic floor disorders

chronic pain disorders

TMJ disorders

what are adverse effects?

skin reaction from electrodes

responses to cardiovascular and strengthening exercises: dyspnea, fatigue, angina, other cardiac related

over exertion of targeted muscles

what are the application parameters?

ensure clean, sterile surface and skin

determine appropriate electrode location

establish baseline resting activity and peak amplitude

set threshold at or above peak amplitude

assess outcome
