ELECTROMYOGRAPHY
Definition
Electromyography (EMG) is a
diagnostic procedure to assess the
health of muscles and the nerve
cells that control them (motor
neurons).

Hypothesis
After exercising, our forearm muscle
can be stronger so that we can
squeeze our fist more tightly!!!

Statements
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

Analysis & Conclusion
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.

Uses of EMG
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.
