Ultium™ Biomechanics Research System

With the world’s best EMG technology at its core, the Ultium-EMG sensor system is a multi-modal, wireless electronic signal portal.
The full-featured EMG sensor samples up to 4,000 times per second, synchronizes in real-time, and demonstrates the lowest baseline noise with the fewest native artifacts of any similar technology.

Sophisticated advances in technology resulted in the patent-pending “SmartLead” system, which transforms the EMG device into an intelligent sensor that delivers virtually any type of biometric and physiological data, from any type of hardware, with the flexibility to accurately capture the most interesting aspects of human movement.


Symmetry & Coordination Tests

Symmetry & Coordination Tests

These various tests allow for the comparison of affected and unaffected sides. Display the EMG and histogram statistics for unilateral, bilateral, multi joint and symmetrical movements. Evaluate the neuromuscular coordination and compare innervation deficiencies between right and left sides.

Average Activation Patterns

Average Activation Patterns

Assess repeated movement sequences and exercises while creating averaged and time normalized EMG patterns. Analyze the typical innervation structure of movements.

EMG Standard Analysis

EMG Standard Analysis

The new Ultium-EMG uses a universal protocol for all kinds of EMG setups. View basic amplitude parameters in selected analysis periods. Use standard graphs and histograms designed for general analysis questions.

Feedback Training

Feedback Training

Use the bar graph display of signals to provide precise training of dysfunctional muscle groups with both acoustic and optical automatic training assistance.

Gait Analysis

Gait Analysis

The protocol for this analysis was designed for unilateral and bilateral investigation of EMG gait patterns in functional walking and running activities. View typical activity characteristics and coordination of muscle groups during walking/running while analyzing left/right, pre/post test comparisons.

Template Training

Template Training

Use background templates for biofeedback training. Create EMG/angle/force templates using the healthy side. Use biofeedback and motor learning concepts to confirm the accuracy of performance.

Patented Innovations

At the heart of Noraxon’s biomechanics platform are patented and FDA-approved technologies that power world-class
data capture. The result is reliable, repeatable and pure data that enables the precise study of human movement.
