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.
Highlights. 1  Electromyography (EMG) is a procedure that assesses the health of muscles and nerves. It may be used diagnose suspected muscle or nerve disorders. 2  There are usually two parts to an EMG procedure: the nerve conduction study and the needle EMG. A nerve conduction study evaluates the nerves that control muscle movement, while a needle EMG assesses nerve activity within the muscles. Abnormal EMG results usually indicate nerve or muscle damage.
