PrOGraM PreVeNtiON OF diSuSe atrOPHy
WHeN?
After an operation or a bone fracture, a limb or a section of a limb is immobilised,
the muscles of this part of the body are affected very quickly by disuse atrophy.
This rapid decrease in muscle volume is mainly due to reflex inhibition and a total
absence of muscle activity. It is also important to note that disuse atrophy tends to
disproportionally affect type I fibres more than type II.
WHy?
To compensate for total or partial inactivity of the muscle following an osteoarticular
injury.
HOW?
In order to prevent disuse atrophy, electrostimulation has to compensate for the total
inactivity of the muscle by reproducing a series of contractions similar to the different
ways in which the muscle functions when it is working normally. The main treatment
phases are carried out with conventional operational frequencies for slow fibres to
compensate for their tendency towards disuse atrophy.
PulSe WidtH
To make it as comfortable as possible for the patient, use pulse widths equivalent to the
chronaxies of the motor nerves of the muscles being stimulated. The mi-SCAN function
can be used to determine the pulse widths suitable for the patient’s muscles.
electrOdeS
Electrodes positioned depending on the muscle to be stimulated, in accordance with
the instructions.
iNteNSity
Use the maximum stimulation energies. The first and second sessions help the patient
become accustomed to the method by gradually increasing the stimulation energy
every 3 or 4 contractions. In the following sessions, it is important to support the
patient’s progress by setting targets which go beyond the energy levels reached in the
previous session.
+teNS
OPtiON
Yes.
- A minimum of 1 channel with muscular work imposed by the Disuse atrophy
programme.
- A maximum of 3 channels with the TENS programme.
• Electrodes positioned on the painful area.
• Sufficient stimulation energy to produce a clear tingling sensation.
Once the +TENS combination has been activated, the message “TENS” appears on the
screen with respect to the channel or channels where the treatment is active. The mi
functions – apart from the mi-SCAN – are also no longer accessible.
Take care to properly observe the correct order for switching on the modules, the order
of switching on that corresponds to the numbering of the channels.
