Electromyography (EMG) is a quantitative measurement of the muscle contraction magnitude necessary for an individual’s ability to conduct manual movements. These movements can include lifting or interacting with various types of product while performing a task.
This evaluation methodology consists of applying surface (skin) electrodes to specific muscles / muscle groups of interest. The testing is non-invasive and will not disrupt movement patterns of a task.
Generally, the purpose of this type of testing is used to predict likelihood of fatigue or measure an employee’s effort, relative to their maximal ability. It is also used to compare required muscle effort during the prototyping stages of product development (tools, equipment, etc.).
