The Biosignalsplux Ergo Explorer Kit provides proper electromyography signal processing that can provide a reference for the analysis of the relationship between work and the required muscular load. Jonsson (1982) described a technique in which the frequency of occurrence of a particular level of EMG is calculated, generating a curve of the probability distribution function of amplitude (APDF). The APDF is the distribution of the muscle contraction levels during a certain observation period.

The APDF concept was originally developed to extract information from EMG records of muscular activity and has been used to analyze EMG in many Ergonomics studies. The amplitude probability of a certain level of contraction is the muscle’s electrical activity probability lower or equal than the level of contraction. The amplitude probability of a certain level can be expressed as the time interval where the signal is less or equal than that level. If the electromyographic activity amplitude is expressed in percentage of the MVC’s calculated value, the amplitude probability distribution is related to the contractions during the workday.
