ELECTROMYOGRAPHY I
[attachment=36809]
EXPERIMENTAL OBJECTIVES
1)To observe and record skeletal muscle tonus as reflected by a basal level of electrical activity associated with the muscle in a resting state.
2)To record maximum clench strength for right and left hands.
3)To observe, record, and correlate motor unit recruitment with increased power of skeletal muscle contraction.
4)To listen to EMG “sounds” and correlate sound intensity with motor unit recruitment.
MATERIALS
BIOPAC electrode lead set (SS2LA/L)
BIOPAC disposable vinyl electrodes (EL503), 6 electrodes per Subject
BIOPAC electrode gel (GEL1) and abrasive pad (ELPAD) or Skin cleanser or alcohol prep
Optional: BIOPAC Headphones (OUT1 for MP3X or 40HP for MP45)
Biopac Student Lab System: software BSL 3.7.5 or above data acquisition unit MP36, MP35, MP30 (Windows only), or MP45
