Electromyography (EMG) (Korean)

In this experiment, students will explore the electrical activity of skeletal muscle by recording a human electromyogram (EMG). The EMG of both voluntary and evoked muscle activity, and nerve conduction velocity will be investigated.

Students will be able to:

• Record EMG during voluntary muscle contractions, and investigate how contractile force changes with increasing demand
• Examine the activity of antagonist muscles and the phenomenon of coactivation
• Record EMG responses evoked by stimulating the median nerve at the wrist
• Measure nerve conduction velocity from the responses evoked by nerve stimulation at the wrist and the elbow
