10. If you retire at the MRA with at least 10, but less than 30 years of service, your benefit will be reduced by 5 percent a year for each year you are under 62, unless you have 20 years of service and your benefit starts when you reach age 60 or later.
Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract. An EMG translates these signals into graphs, sounds or numerical values that a specialist interprets.
An EMG is the summation of action potentials from the muscle fibers under the electrodes placed on the skin. The more muscles that fire, the greater the amount of action potentials recorded and the greater the EMG reading. EMG recording: The EMG is recorded by using a electrode placed on the muscle. The electrical activity measured by each muscle electrode and the ground electrode are sent to an amplifier. The amplifier eliminates random voltages caused by electrical noise by subtracting the signal from the ground electrode from the muscle electrode, producing the raw EMG.
