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.
EMG may be used to evaluate many problems or disorders including, but not limited to, the following: 1  Neuromuscular diseases, such as myasthenia gravis. 2  Motor problems, such as involuntary muscle twitching. 3  Nerve compression or injury, such as carpal tunnel syndrome. 4  Nerve root injury, such as sciatica.
