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