Electromyography (EMG)

Investigation and management of muscle and nerve disorders.

Siow Neurology, Headache and Pain centres have onsite EMG equipment. This treatment is used for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed with an Electromyograph, to produce a record called an electromyogram. An injection into various muscles will pick up the electrical activity given out by muscles and tell us if there is nerve or muscle disease from this.

EMG is most often used when patients have symptoms of weakness, and examination shows impaired muscle strength. It can help to tell the difference between muscle weakness caused by injury of a nerve attached to a muscle and weakness due to neurological disorders.

There is little or no preparation for EMG. Body lotions are to be avoided prior to the use of EMG as this may reduce the reading. Blood Thinners are also to be avoided as again this may distort the electromyogram reading.
