4 Purpose
4.1 EMG and pressure feedback
4.1.1 What is biofeedback?
Feedback is a way of managing a system by communicating back to it the results of its (previous)
performance. Biofeedback is a way of managing certain physical functions by means of a feedback
mechanism. A feedback training enables patients to adjust their actions to suit their physical capabilities
and to bring these under control through continuous feedback.
Indications:
Biofeedback is being used successfully in many areas. It offers a wide range of treatment options for
many applications, including incontinence, muscle training, post-surgical rehabilitation, RSI and lower
back complaints.
4.2 Muscle stimulation
4.2.1 Indications/contra-indications and harmful effects of muscle stimulation
Indications:
Relaxation of muscular spasms.
Prevention or treatment of degenerated muscles.
Stimulation of local circulation.
Rehabilitation.
Stimulation of the calf muscle immediately after an operation, to prevent thrombosis.
Strengthening or enlargement of the movement range.
Contra-indications:
The apparatus should not be used on patients with a pacemaker.
The apparatus should not be used on carcinomas.
Do not attach electrodes at places where current is released in the area of the carotid sinus
(ventral side of the neck).
Do not attach electrodes at places where current is released transcerebrally (i.e. through the
head).
Do not attach electrodes at places where current is released transthoracically (releasing current
to the heart can lead to cardiac arrhythmia).
Warnings:
The long-term effects of chronic electrical stimulation are unknown.
The safety of therapeutic electrical stimulation during pregnancy has not been established.
Electrical stimulation should not be applied to swollen, infected or inflamed areas of skin
(phlebitis, thrombophlebitis, caput medusae, etc.).
See also Chapter 3, Precautionary measures, for general warnings and precautionary measures.
Precautionary measures:
Suitable precautionary measures must be observed when treating patients in whom heart
problems are suspected or have been diagnosed, or who suffer from epilepsy.
Caution must be exercised if bleeding occurs rapidly after acute injury or a fracture.
Caution must be exercised after a recent operation, as the healing process can be disrupted by
muscle contraction.
Caution must be exercised in the menstruating uterus.
Caution must be exercised with sensitive areas of skin.
In some patients, skin irritation or hypersensitivity can arise due to electrical stimulation or an
electrically conductive medium. The irritation can usually be reduced by using a different
conductive medium or by attaching the electrodes elsewhere.
See also Chapter 3, Precautionary measures, for general warnings and precautionary measures.
7
Harmful effects:
Cases of skin irritation and burns under the electrodes have been reported as a result of
therapeutic electrical stimulation.
4.2.2 Form of current
Muscle stimulation (to improve the muscle function):
Neuromuscular Electrical Stimulation (NMES) is the use of electrical stimulation to activate
muscle tissue by stimulating the intact peripheral nerve.
Functional Electrical Stimulation (FES) is the use of NMES to replace orthoses.
Electrical Muscle Stimulation (EMS) is the use of electrical stimulation to directly activate
denervated muscle tissue.
Muscle stimulation is often used with the symmetrical biphasic pulsed form of current. This form of current
is also fully compensated (i.e. it has no residual DC components). See Fig. 11.1 for an illustration. The
specified phase length applies to both pulse phases, as a result of which the quantity of energy available
is twice that of the asymmetric pulsed form of current. See section 10 for the available parameters.
Muscle stimulation is often used in combination with an expansion/contraction program, in which periods
of effort and rest are alternated. See Fig. 11.2 and section 10 for the available parameters.

6 Installation
Initial procedures
Take the Myomed 134 and any extra parts out of the cardboard packaging and check everything
for possible transport damage
Check that the voltage on the serial plate of the ENA-1524 mains voltage adapter (100 V 240
V) corresponds to the available mains supply
Connect the ENA-1524 mains voltage adapter to the connector [10]
Insert the mains voltage adapter into a wall socket
CAUTION:
Only connect the Myomed 134 to an adapter of type ENA-1524, as this adapter forms an integral
part of the power supply circuit that guarantees safe operation
Do not use direct current (DC)
Place the apparatus so that no one can trip over the power cable and so that the power cable
cannot be accidentally pulled out during treatment
Make sure that the adapter is well earthed
The adapter should only be connected to an earthed wall socket that satisfies the applicable national and
local electricity regulations for medical environments.
7 Use of the electrodes
CAUTION:
The connection of accessories that are not specified by the manufacturer can adversely affect the
safety of the patient and the proper working of the apparatus and is therefore not permitted
NB:
The following description is applicable to electrotherapy in general. The electrolytic side-effects
mentioned below do not apply to the Myomed 134, because this apparatus only generates fully
compensated TENS currents that do not contain any DC component
7.1 Before the treatment
Check whether the contra-indications and warnings described in sections 4.1 and 4.2 apply to the
patient
Test the heat sensitivity of the area to be treated
Rinse clean the area to be treated. Hairy skin surfaces should be shaved
7.2 Self-adhesive electrodes
Self-adhesive electrodes have a higher serial impedance than rubber carbon electrodes. As a result the
stimulator can terminate the treatment at higher current amplitudes. If this happens, it is advisable to
continue the treatment with rubber carbon electrodes and well-moistened sponges.
9
7.3 Current density
In conformity with IEC 60601-2-10, the maximum permissible ‘current density’ is 2 mA RMS per cm². With
smaller electrodes, such as the 3.2 mm self-adhesive electrodes, this is not the case. To check whether
the maximum permissible current density of 2 mA RMS per cm² is being exceeded, divide the RMS
output current in mA by the effective electrode surface in cm². The result should be less than 2. With
asymmetric TENS currents the RMS value of the output current can be calculated as follows:
IRMS = Ipeak √ ( Phase length [µs] * pulse frequency [Hz] * 10-6 )
With symmetric TENS currents the phase length must be multiplied by 2. The value of the peak
current Ipeak can be read off on the current display.
The electrodes must be attached carefully but firmly. The use of small electrodes can cause skin irritation
and burns at high current amplitudes.
7.4 Opening and closing reactions
This apparatus releases constant current (CC), which can cause unpleasant opening and closing
reactions if the electrodes are not properly attached or come loose from the skin. When attaching and
removing electrodes, make sure that the output current has been set to 0 mA.

Procedure:
If the patient does not remain above the pre-set threshold during the EMG working time then the
apparatus will automatically be switched to Stimulation and the current will drop to the pre-set intensity
of current. When the whole of the stimulation program has been completed the apparatus will
automatically switch to the EMG program. The number of repetitions is set under the ‘cycle settings’
parameter
The current can be adjusted during the contraction. Select current channel (button 4 for channel 1) and
adjust the intensity with the central control button [6]
