ELECTROMYOGRAPHY
Definition
Electromyography (EMG) is a
diagnostic procedure to assess the
health of muscles and the nerve
cells that control them (motor
neurons).
Uses
Clinical/ Biomedical application

Muscle detection

Muscle decomposition

Muscle processing

Muscle classification
Thus, this EMG paper
provides neurologists that to
analysis procedure

After exercising, our forearm muscle can
be stronger so that we can squeeze our
fist more tightly!!!


It is easy to figure out what is wrong with
muscle

It is not very expensive

It does not take space widely

It can not hurt patients

Our hypothesis was disproved and therefore, our results
shows that after exercising, forearm muscle became fatigue
and cannot squeeze tightly before doing exercise.
Technically, there are four stages muscle tension , lowest,
low, high, highest, and, in order to get accurate levels, we
have to squeeze our fists stronger and stronger. However,
we sometime, squeezed incorrectly at wrong stage.
Experiment average should be lower than control average
when we lift weight. If the results did not turn out as
expected, the experiment could have been repeated.

Psychologists employ EMG to intervene with
problems attributed to excessive psycho
physiological arousal.
Rehabilitation nurses and therapists treat
incontinence related to dysfunction of the pelvic
floor muscles with EMG feedback.
Physiatrists, orthopedists, and neurologists may be
interested in EMG procedures to enhance
diagnosis of movement disorders as well as
monitor the effects of medicines and surgical
interventions designed to impact muscle activity.
