muscles which only have type II fibers, like the orbicular muscle; however, the majority of
human body muscles is composed of a combination of the two types. Studies on the
distribution of fibers in the muscle have highlighted the close relationship between the
(tonic or phasic) motoneuron and the functional features of the fibers it innervates;
moreover, they have proved that a specific motor action (particularly in sports) can lead
to a functional adaptation of fibers and change their metabolic features.
Stimulation intensity
The intensity value required to trigger contraction depends on patients, electrode
placement, adipose tissue, perspiration, possible hairs on the treatment surface etc.
Therefore, the same current intensity may give different sensations to different people,
in different days or body sides. It is advisable to regulate the intensity during the same
session to contrast accommodation, in order to obtain the same contraction.
The current intensity for the different phases is suggested with an approximate value
and can be modified on the basis of individual sensations.
- Moderate: the muscle does not tire, even during long treatment. The contraction is
agreeable and tolerable. First level of the intensity graph.
- Intermediate: the muscle is visibly contracted but the stimulation does not trigger the
joint movement. Second level of the intensity graph.
- High: the muscle is contracted noticeably. The muscle contraction would extend or
bend the limb if not blocked. Third level in the intensity graph.
- Maximal: the muscle is contracted maximally. This is an intense treatment
that should be performed only after many applications.
