P7
Always use 2 channels and 4 electrodes with Program 7. A modulated pulse duration
stimulation is obtained, but since the channels are alternately active, a massaging,
pumping effect is experienced. Place the electrodes as for
high-frequency stimulation when a pain relieving and massaging effect is desired.
P8
An increase in the tension of the contractured muscle fibres and the crushing of the
capillary network resulting from this causes a decrease in the blood flow and a gradual
accumulation of acid metabolites and free radicals. Without treatment, there is a risk
that the contracture will become chronic and genuine atrophy of the capillary network
may gradually occur. In addition to the general effect of increasing endorphin production
in the hypothalamus, which elevates the pain perception threshold, there is a very
significant localised effect. The 5 muscle twitches induced every second by stimulation
produce very significant hyperaemia, which drains the acid metabolites and free radicals
that had accumulated in the chronically contractured muscle areas.
P9
The principle is to cause a significant influx of tactile sensitivity in order to restrict the
entry of pain impulses upon their return to the posterior horn of the spinal cord. We
must therefore stimulate the sensitivity fibres on the skin of the painful area. To do this,
it is necessary to use a frequency that is the same as the operational frequencies for the
tactile sensitivity nerve fibres that could attend 100 Hz
P10
A muscle that is normally innervated, after a period of immobilisation or diminished
movement due to pain or restricted range of motion, rapidly decreases in volume. This
decrease depends on the degree and duration of the functional deficit. Slow fibres (type
I) in particular are affected by disuse atrophy.
