Neuro-muscular electrostimulation, as well as the voluntary contraction, involves a contraction phase (stimulation), followed by a rest phase (pause). The REST phase is extremely important for the muscle; during the contraction, in fact, capillary circulation
Read moreWe know that an electrical generator, to produce a current flow, must be “closed” on a load. The load, in the electro stimulation, is represented by the muscle to be stimulated. The connection between the
Read moreThe success of the therapy could be conditioned from different factors and can be different from patient to patient. The position of the electrodes is one of the elements that can highly influence the therapeutic
Read moreThere are no mathematical formulae for determining the optimum level of electrical stimulation. The level of intensity must be enough to cause the required level of contraction but without discomfort or pain for the patient.
Read moreAccording to current scientific evidence, the most suitable waveform in order to obtain muscle contraction, using low energy impulses, is the symmetrical two-phase impulse. The impulse must be wide enough to allow a transfer of
Read moreThe stimulation frequency would have an important role in the treatment efficiency – but there are many differences of opinion which exist even now; LOW frequencies (around 10Hz) should produce a delayed, and less intense
Read moreOf course the gate control theory is not the only one in the pain modulation field; a more up-to-date interpretation foresees a chemical-humoral control mechanism, based on the stimulated production of endogenous substances “similar to
Read moreWe defined the better wave shape to be used, and a single pulse could also produce a momentary contraction like a “wriggle”; any way, to obtain a sustained contraction, we must supply a pulse train,
Read moreR. Melzac and P. Wall’s gate control theory presented in 1965, is based on the existence of different types of nerve fibers in charge of “sensation” transmission, from the human body fringe area to the
Read morePain is a complex sensation, which originates from the sensitive nerve terminals of the pain zone. The pain is then recognised and codified by the central nervous system which in its turn combats or lessens
