Biomechanics

Modular construction...extreme flexibility

MP systems offer features to support nearly every physiological recording scenario. The following advanced features apply to the application you selected.

If you don't see an Advanced Feature that interests you, please contact BIOPAC so we can identify the best solution for your particular need.

Actigraphy

Actigraphy noninvasively measures cycles of activity and sleep (rest) over days or even weeks, typically to assess sleep disorders and other sleep-related criteria. Use the Actigraphy Analysis licensed feature in AcqKnowledge® to record long-term accelerometer data of mobile subjects and then analyze sleep and activity patterns; correlate activity levels with GPS positioning for more detailed […]

Automated EMG Analysis

AcqKnowledge includes a number of powerful automated EMG analysis features, including Derive Average Rectified EMG Derive Integrated EMG Root Means Square EMG EMG Frequency & Power Analysis   Locate Muscle Activation Derive Average Rectified EMG   Derive Average rectified EMG (ARV) is defined as a time-windowed mean of the absolute value of the signal. ARV […]

Ergonomics Evaluation

Body position and posture can be analyzed over a wide range of static and dynamic conditions and these measurements can be used to determine the ergonomic characteristics of a specific work activity or environment. To reliably record head tilt with respect to the X-, Y- and Z-axes simultaneously, place a TSD109 accelerometer on the head. To […]

Gait Analysis

Simultaneously acquire up to 16 channels of gait-specific data, including heel-toe, goniometry, accelerometry and more. One setup might incorporate two channels for heel/toe strike timing, ten channels for EMG signals and four channels of goniometry data. When using a force plate, the six force and moment signals are sent directly from the force plate amplifier to […]

H-Reflex Methodology

The Hoffmann reflex (H-reflex) is an electrically induced reflex that bypasses the muscle spindle. H-reflex is a useful measure to assess modulation of monosynaptic reflex activity in the spinal cord. H-reflex studies can be set up multiple ways and users should determine the best approach for their required protocol; BIOPAC cannot recommend a “standard” approach […]

Interface With Imaging Equipment

The MP System can be synchronized with imaging systems (MRI, video capture, etc.). An imaging system can be used to trigger the recording or, alternatively, the MP System can be used to trigger the imager. With CAM-HFR-A and AcqKnowledge media tools, it’s possible to obtain synchronization within 1 video frame (10 ms) between physiological data […]

Isometric Contraction

Isolate a wide range of muscle groups and evaluate their isometric contraction characteristics for performance quantification. Configure the TSD121C hand dynamometer to measure handgrip force or a wide range of pulling forces. To measure pulling forces, secure the dynamometer to a fixed surface, then connect a tether between the dynamometer and the muscle group under investigation. […]

Isotonic Contraction

Examine muscle groups for isotonic performance by placing the TSD109 accelerometer on a target limb actively hoisting weights of specific sizes. The accelerometer records the precise time the weight moves, and the subsequent acceleration of that movement.

Range of Motion (ROM)

Use AcqKnowledge® to determine the velocity of motion occurring during physical activity. All parts of the body can be evaluated for range of motion. 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 plotting feature to inspect motion resulting from two […]
