Biomechanics – BME

The Student Lab System has a comprehensive ability to monitor gait and other mechanical responses. The system works with goniometers, accelerometers and heel-toe strike transducers. Biopotential signals such as EMG can be synchronously recorded. Use the hand dynamometer and accelerometer to measure isotonic and isometric performance. Goniometers are available for evaluating one or two degrees of freedom from the same joint (e.g. wrist flexion/extension and radial/ulnar deviations). Use the X/Y display mode to monitor motion resulting from two degrees of freedom. Use electrical analogs to model mechanical systems, demonstrate principles of biomechanical resonance or inertial navigation (acceleration, velocity and position), or convert gravity vectors into associated angles.

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.…

Goniometers & Torsiometers - MP3X/45 Dual-axis devices provide simultaneous measurements around two orthogonal rotational axes and single output devices measure axial rotation about a single plane. Use with MP3X or MP45 unit. SS20L and SS21L dual-axis goniometers measure limb angular movement (e.g., wrist flexion/extension and radial/ulnar deviations). SS22L and SS23L single-axis torsiometers measure forearm pronation/supination. SS24L single-axis goniometer measure joint movement…

Accelerometers - MP3X Tri-axial Accelerometers connect directly to the MP3X unit to provide three outputs, each simultaneously measuring accelerations in the X, Y, and Z directions, requiring no additional amplification. One input channel is required for each output—three input channels are required to measure each axis simultaneously. The accelerometers have a frequency response which extends from DC to…

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…

Hand Dynamometer - MP3X Use this lightweight, ergonomically designed hand dynamometer to measure grip; clench force range 0-50 kgf. Use in isolation or combine with EMG recordings for in-depth studies of muscular activity. The isometric design improves experiment repeatability and accuracy, and simple calibration makes the device very easy to use. Transducer provides direct readings in kilograms or pounds. When…

Heel/Toe Strike Transducer - MP3X/46/45 Use this transducer to record heel and toe strike activity as the subject walks. The SS28LA uses two force sensitive resistors (FSR); typically, one FSR is attached to the sole of a shoe at the heel and the other FSR is attached at the toes. The FSRs indicate the precise pressure placed on the heel…
