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

Hypothesis

After exercising, our forearm muscle

can be stronger so that we can

squeeze our fist more tightly!!!

MaterialsBIOPAC electrode lead set (SS2L)

BIOPAC disposable vinyl electrodes (EL 503)

Computer system

BIOPAC student lab 3.7 for PC running Windows

BIOPAC acquisition unit (MP35/30)

BIOPAC wall transformer ( AC 100A)

BIOPAC serial cable (CBLSERA) or USB cable (USB1W) if using a USB port

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.
