Electromyography Assessment

An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, or recruitment order or to analyze the biomechanics of human movement.

Electromyography (EMG)

EMG provides information about how the muscles work during contraction and used to see how each muscle acts and how it contributes to the movement Electromyogram (EMG) is a device that is used to record the electrical activity of muscles. When muscles are active, they produce an electrical current. This current is usually proportional to the level of the muscle activity. EMG can be used to detect abnormal electrical activity of muscle that can occur in many diseases and conditions, including muscular dystrophy, inflammation of muscles, pinched nerves, peripheral nerve damage (damage to nerves in the arms and legs), amyotrophic lateral sclerosis (ALS), myasthenia gravis, disc herniation, and others. Our Noraxon DTS EMG System is specially designed for both clinical and biomechanical applications and its wireless feature enable GSA specialists to perform EMG measurements without any limitations.

Why Noraxon DTS?

The Desktop Direct Transmission System (DTS) for EMG and other biomechanical sensors directly transmits data from the electrode or sensor site to a desktop receiver. This direct transmission concept greatly simplifies the arrangement of EMG measurements by eliminating the need to arrange cable connections between the EMG electrodes and EMG amplifier. The small light weight probes are also beneficial for small subjects like children.


Symmetry and 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:
Clinicians can assess repeated movement sequences and exercises while creating averaged and time normalized EMG patterns. Analyze the typical innervation structure of movements.

EMG Standard Analysis:
The DTS uses 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:
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:
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/posttest comparisons. Symmetry, timing and curve characteristics are summarized.
