an ampere). Numerous studies showed that the currents in microamperes increase
the APT synthesis.
Usually the MENS therapy has two different phases: the first aims to reduce the pain
sensation perceived by the patient, while the second promotes the protein and APT
synthesis, accelerating the tissue reparative processes. Usually the treatment
duration ranges between 15 and 30 minutes for the first phase and between 5 and
10 minutes for the second phase. MENS are an interesting instrumental therapy that
can be used in many disorders, and the use of MENS together with other
instrumental therapies such as for example laser and TENS can provide excellent
clinic results that are usually difficult to reach.
Ionophoresis
Ionophoresis is an electrotherapy transmitting pharmacological substances inside
the tissue thanks to continuous, unidirectional electric currents.
Ionophoresis is based on the ionic dissociation of medicinal substances with low
molecular weight, after being dissolved in water.
Knowing whether, after being dissociated under ionic form, the active part of the
medicine has positive or negative charge is fundamental, since it allows the correct
positioning of the drug according to the direction of the electric flux.
The ions of the medicinal substance are transmitted inside the organism through
cutaneous areas which oppose a low resistance to the current. Thus, the cellular
membranes are electrically modified by the ions permeating them.
Denervated
The stimulation of a denervated muscle differs from the stimulation of a healthy
muscle, since the activation of muscular fibers requires particular currents.
In the presence of a traumatic lesion of the peripheral nerves, measuring the
chronaxie determines whether the denervation is limited,
Excitomotor treatments aim to maintain the trophism and to limit muscular sclerosis,
thus at the end of the denervation process – which may last several months – the
functionality of the muscle is maintained. The correct setting of the stimulation
parameters is fundamental for the efficiency of the treatment; therefore, the
parameters have to be defined according to the single patients and have to be
adapted as the treatment proceeds.
Rectangular currents
The rectangular current is characterized by a single rectangular impulse, which
varies quickly from zero to the maximum value of the set up intensity, from a
contraction duration equal to the impulse duration, from a recovery time
corresponding to the time of muscular recovery. The rectangular shape of the
impulse causes the muscular contraction, the duration of the impulse determines a
