L01 Electromyography I

Biopac Student Lab EMG
BSL EMG lesson I investigates the properties of skeletal muscle. Students record the EMG data associated with the maximum grip clench for their dominant hand and then do the same for their non-dominant hand. The system will record and display both the raw and integrated EMG signals. This lesson allows the students to compare the grip clench between their two arms and listen to the sound of their EMG. It is also possible for students to perform a cross group analysis.

Experimental Objectives

  1. To observe and record skeletal muscle tonus as reflected by a basal level of electrical activity associated with the muscle in the resting state.
  2. To record the maximum grip clench for the right and the left hand.
  3. To observe, record and correlate motor unit recruitment with the increased power of skeletal muscle contraction.
  4. To listen to EMG “sounds” and correlate sound intensity with motor unit recruitment.

Tasks Performed by the Student

BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL System station.

Mobita Advances Prestimulus EEG Research

The Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
