2. Electromyography (EMG)is an electrodiagnostic medicine
technique for evaluating and recording the electrical activity
produced by skeletalmuscles

3. EMG is performed using an instrument called an electromyograph
to produce a record called anelectromyogram

4. • The signalscan be analyzed to detect medical abnormalities,
activation level, or recruitment order, orto analyze the
biomechanics of human oranimal Movement
• An electromyograph detects the electric potential generated by
musclecells

5. EMG electrodes

6. There are two main types ofEMG
electrodes:
Surface (orskin electrodes) and Inserted
electrodes
Inserted electrodes have further two
types:
1.Needle and
2. Fine wire electrodes.

7. Surface electrode measuresthe potential available
from the surface of theskin.
1.Metal Plate Electrodes
2.Suction Cup Electrodes or Welsh Cup Electrodes
3.Adhesive Type Electrodes
4 . M u l t i p o i n t Type Electrodes
5.Floating Electrodes
6. Ear Clips a n d Scalp Electrodes
