The Mega ME-3000-P Muscle Testing System is an advanced multi-channel sEMG system for rapid and effective diagnosis of muscular dysfunction as part of a functional assessment. Muscle recruitment is observed during actual dynamic movement to clearly show patterns of inappropriate motor control that is the underlying cause of chronic pain in many patients. The patient can see graphical evidence of the muscle difficulty as therapy progresses and can observe improvement as it occurs. There is better patient compliance and motivation.

For conditions of movement dysfunction, sEMG is a versatile muscular analysis and diagnostic technique. Assessments can be performed on all of the surface skeletal muscles. Patients showing carpal tunnel syndrome, shoulder pain and lower back pain benefit remarkably well from sEMG testing. 

Some of the many conditions for which sEMG are effective are:

• Chronic pain
• Myofascial pain
• Repetitive Strain Injury

• The amplitude of the signal shows muscle recruitment and level of exertion. It shows muscles that are overactive when they should be quiet and shows compensatory movement patterns that must be corrected. 

• The frequency of the signal shows the level of metabolic fatigue. sEMG fatigue measurements are automatically compared with a normative data base. A dysfunctional muscle shows fast fatigue onset and slow recovery. This requires a modified program of therapy for good results. A sEMG assessment shows where muscle retraining is needed prior to muscle strengthening.

The rate of false positive diagnosis is very low - less than 5%. This is because of the detailed reporting which is generated and because the resulting therapy program can be regularly evaluated with sEMG and modified for optimum results. In patients showing good motivation for recovery, successful outcomes are better than 95%.
