Electromyography (EMG)

electromyogram-(EMG)
PropertiesDetails
SFDA Classification Class IIb
Purpose of UseMonitor and record the electrical activity of the muscles.
Work Location & End-UserWork location: hospital wards
End-User: Doctor
Parts & Accessories• computer
• battery
• Electrodes and wires

Pickup types:
• Superficial: more widely used and more extensive in capturing electrical signals
Consists of:
small metal disc
Made of silver chloride

• needle
Consists of:
A very thin wire is inserted into the muscle
Insulated metal conducts electricity on one side and exposed on the other
his problems:
The muscle may be involuntarily tightened as a result of pain, which leads to inaccuracy
OperationThe current is sent through the nerve and then the signal from the muscle contraction is measured
After the signal received from the electrodes is amplified it is displayed on the computer

Connection:
Patient head > Electrodes > Amplification > Recording > Signal display

Device information is taken by:
muscle capacity
muscle succession
The fibers that make up the muscle
Common ProblemsThe need to replace the consumable parts
Malfunction of the electrode connections and the electrical circuit
Faulty signal pickup may occur due to noise from ambient light and electrical appliances

Problem solving:
Signal amplification
Noise removal through filtration
