Common Core Shifts. This resource describes in detail the six instructional shifts needed to effectively implement the Common Core State Standards (CCSS) in ELA/Literacy and the six shifts to implement them in Math.
1 Electromyography (EMG) is a procedure that assesses the health of muscles and nerves. It may be used diagnose suspected muscle or nerve disorders.  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.
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.
