In a Presidential System, the head of state and head of government tends to be the same person. In a Parliamentary System, minority groups can form third, fourth, and fifth parties and have much more influence in government than in a Presidential System where third parties are marginalized (many complexities here).
Electromyography (EMG) uses small needle electrodes to measure the electrical currents in a muscle as it contracts. While an EMG canât definitively diagnose metabolic disease, it can be used to rule out a number of other types of neuromuscular disease that cause similar patterns of weakness.
Why is an EMG test ordered? An EMG lab may be ordered for patients who experience numbness, tingling, pain, weakness, or muscle cramping. Nerve conduction studies and EMGs are types of tests that the spine physician may use to diagnose symptoms.
