[Chronic progressive obliterating arteriopathy and muscle fatigue: the role of frequency analysis of the electromyographic signal]

Clinical evaluation of patients with peripheral arterial disease (PAD) is mainly based on Fontaine's classification, in which pain is the most important element. The use of objective techniques can allow a more precise evaluation, since pain is always subjective. In PAD patients, pain is frequently associated with early fatigue. Peripheral muscle fatigue can be easily assessed by a particular electromyographical method, based on the frequency analysis of the signal. In PAD patients, this method can provide objective information on muscular performance, with possible uses in medicine, surgery, rehabilitation and occupational medicine.
