EMG 1 investigates the properties of skeletal muscle. Students record the EMG data associated with the maximum clench strength for their dominant hand and non-dominant hand. The system records and displays both the raw and integrated EMG signals. Students compare clench strength between their two arms and listen to the sound of their EMG. It is also possible for students to perform a cross-group analysis.
To record maximum clench strength for right and left hands.
To observe, record, and correlate motor unit recruitment with increased power of skeletal muscle contraction
Optional: To listen to EMG sounds and correlate sound intensity with motor unit recruitment.
Tasks Performed by the Student
Record EMG from the dominant and non-dominant forearms.
Clench fist four times, squeezing harder each time to reach maximum clench strength with the fourth clench.
Optional: Listen to the sound of their EMG.
Raw and Integrated EMG signals can be overlapped for easy interpretation of the data.
Comparison between the dominant and non-dominant arms.
The students listen to the sound of motor unit recruitment.
