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.
Electrodiagnostic medicine studies diseases of the nerves and muscles. The EMG test your doctor has recommended studies if your muscles and nerves are working right. You can have problems with your muscles and nerves in only one part of your body or throughout your body. The EMG doctor examines you to decide what tests to do.
