The Different Phases - MTR+ DuoBravo Bedienungsanleitung

DuoBravo offers programs that can consist of one or more phases. There are basically three
different types of these phases which can be therapeutically combined in a useful way.
a) EMG (= Electromyography) - purely active biofeedback training is carried out. The patient
tightens the muscle according to the requirements in the display for the specified time and
then releases it again. The device gives an acoustic and visual feedback about the strength and
duration of contraction and relaxation. If the relaxation is target of the treatment, the positive
signal will be given in the active period (that is indicated by the fist) as well, if muscle tension
will be below the threshold. In an EMG-phase the device only measures and doesn't give any
current.
b) STIM - In this phase the muscle is stimulated passively. Here is a distinction between:
- Continuous current (CON), which does not include breaks and always remains the
same.
- Modulated current, which also flows without a break, but
frequency and pulse width change in a predetermined rhythm. This way, the feeling of
rising and falling intensity is generated.
- Current in work/rest-rhythm, where a muscle is stimulated in each work phase to
contract as strong as possible. In all subsequent rest phases the muscle shall be relaxed
as far as possible, to avoid strain.
The effect of current delivered by the device will vary depending on configuration. It may
have circulatory-enhancing, detoxifying, relaxing, strengthening and pain-reducing effect.
During the stimulation DuoBravo cannot measure EMG, but the muscle tone can be measured
in the relaxation sequences of work/rest-periods. This control may be necessary to avoid any
overstrain of the treated muscle.
c) ETS (= EMG-triggered stimulation) - this is a combination of active biofeedback training
(see above - EMG) and immediately afterwards passive electrical stimulation (see above -
STIM). If the patient succeeds to reach a preset threshold for the muscle tension by his own
activities, the device automatically transmits current that supports the muscle to contract. The
movement generated by the current, is initiated by the brain this way. It's the target to improve
the force of the own muscle contraction. In neurological treatment, it is often intended to
remove interferences in neural pathways, so that the muscle can be actively moved later -
without the help of a device.
