Description
EMG recordings are integral to the NeuroCom®, a division of Natus® Postural Evoked Response test (PER), which analyzes the automatic responses of a patient's gastrocnemius and tibialis muscles to an unexpected external balance perturbation.
- Stimulus: Toes up, toes down platform rotations at 25°/second or 50°/second through 2°, 4°, or 8° arc are standard. Additional backward and forward horizontal platform translations are standard on the EquiTest and SMART EquiTest systems.
- Electrodes: Active Surface Electrodes with built in amplification eliminate cable artifacts and enhance signal quality.
- Display: Real time display for monitoring electrode placement and data collection.
- Data review: Individual trials can be accepted or rejected prior to calculation of the rectified average.
- Data analysis: Interactive cursor routine for labeling waveforms. Absolute latencies, response amplitudes and area under the curve are calculated accordingly.
- Hard copy printout: Results are immediately available for inclusion in medical records.
