Low and medium Frequency Electrotherapy - Implox

The two classifications most commonly used to assess the correct amplitude are described below.
1. Classification bases on the sensation created in the patient:
a. submitis (amplitude at which the stimulus is just imperceptible);
b. mitis (amplitude at which the stimulus is just perceptible);
c. normalis (amplitude at which the stimulus is distinctly perceptible);
d. fortis (amplitude at which the stimulus is increased to the limit of tolerance).
A disadvantage of this classification is that it is, in fact, dependent on verbal information from the patient. In addition,
it disregards any motor activity.
2. Classification according to both sensory and motor stimulation levels:
a. subsensory stimulation level;
b. sensory stimulation level;
c. motor stimulation level )clearly perceptible muscle contractions);
d. limit of tolerance (powerful, but not quite painful muscle contractions);
e. pain threshold.
In practice, this second classification is easier to use. However, it is still an open question as to whether a motor
stimulation level is really below the limit of tolerance. In pathological cases, the sequence can change. Many factors
play a role in this, such as the nature of the condition, the sensitivity of the patient, and the metabolism of the skin.
From this it will be clear that it is impossible to give exact figures with respect to the limits between the various
stimulation levels. In the examples of treatment, we shall keep to Classification 2. If the aim of the treatment is to
evoke a motor response, it will also be indicated whether the current amplitude may be increased to the limit of
tolerance or to the pain threshold.
