Muscular – Human

Record surface EMG data to investigate the properties of skeletal muscle. Record and display raw and integrated EMG signals; overlap the signals for better correlation of the data. Measure strength and repeat trials for motor unit recruitment, summation and fatigue. Use the reflex hammer transducer to study reflex response (neural control), or add the dynamometer to study handgrip strength profiles. Use the finger twitch transducer for threshold, summation, tetanus and fatigue analysis.

Design muscular biofeedback experiments by selecting different types of muscles and variations of contractions/activities relating to biofeedback that the subject will perform; measure changes in surface EMG with maximal contraction, as compared to baseline, incorporating different combinations of visual and auditory feedback (see BSL PRO Lesson H36).

Students can listen to the muscle activity through headphones and note the increase in sound intensity as grip strength is increased.

General-purpose Electrodes These pre-gelled disposable electrodes have a circular contact and are most suitable for short-term recordings, including surface EMG, ECG, EOG, etc. The small vinyl backing allows close electrode placement where necessary, and a slightly less firm adhesive allows "ouchless" removal. The electrodes incorporate liquid electrolyte gel and moderately-high chloride salt concentration for quick, accurate readings.…

Cloth Base Electrodes These disposable cloth base electrodes adhere well and are particularly useful for applications on non-conforming surfaces, such as facial EMG measurements. Due to hydrogel electrolyte concentration, these are also suitable for electrical stimulation studies. Electrodes have a circular contact on a square backing. The adhesive solid hydrogel ensures good contact, and the silver-silver chloride (Ag/AgCl)…

Headphones These wide response high-fidelity headphones are used for auditory stimulus (short tones or clicks) or to listen to physiological signals (like EMG) directly. The headphones are comfortable and lightweight and include a 2-meter cable so the Subject can be seated a comfortable distance from the acquisition unit. Simple Sensor connector interfaces with the “Analog Outport” port…

Finger Goniometer 35 mm - MP3X/45 SS24L is used to measure finger joint movement. The gauge mechanism in this single-axis goniometer allows for accurate measurement of polycentric joints. Telescopic endblocks compensate for changes in distance between the two mounting points as the limb moves.  One MP3X/45 channel is required for output. Use medical adhesive tape (TAPE2) to attach to the body. See…

Reflex Hammer Transducer - MP3X/45 The SS36L is a classic reflex hammer with a transducer attached to perform reflex measurements and record strike magnitude. Being able to measure the strength of impact allows students to take threshold measurements; that is, they can measure how much of an impact is needed to elicit a response. The SS36L uses a Taylor Hammer—the most…
