Combination therapy is the combined application of ultrasound and electrical stimulation.
With combination therapy the metal surface of the ultrasound applicator becomes the nega-
tive electricalstimulation electrode, while the lead wire with the red connector remains the
positive electrical stimulation electrode. Combination therapy is available with all current
waveforms, but limited to channel 2. Combination therapy is typically used for the reduction
of muscle spasm.The combined Contra-indications and Adverse Effects of paragraph 4.1
and 4.2 apply

Myofeedback is a form of feedback, in which the patient receives electronically recorded
information about his own physiological processes. The electromyographic recording used
in the diagnostics and treatment of the moving mechanism is an indispensable supplement
to the study of movement. When we place electrodes on the skin to obtain information from
an EMG signal about the underlying musculature, we must be acquainted with the develop-
ment of the EMG signal and the construction and function of the motor mechanism. Thus,
properties and mutations in the musculature, the joints system, the sensory and the neural
system can be found in the motor system and also in the EMG recording. Surface EMG pro-
vides us with detailed information about the organ-specific properties of a muscle, such as:

Effective Radiation Area (ERA):
expressed in cm², defines the cross-sectional area of the
ultrasound beam (See technical specifications for details). The Effective Radiation Area is
fixed and defined by the size of the ultrasound applicator.
Ultrasound Power:
is the ultrasound output expressed in Watt. The ultrasound output
display can be toggled between Watt and Watt/cm². In pulsed mode the power during the
pulse is displayed. The time averaged power can be obtained by multiplying this value with
the Duty Cycle.
Ultrasound Amplitude:
expressed in Watt/cm², is the quotient of Ultrasound Power and
Effective Radiation Area. The ultrasound output display can be toggled between Watt and
Watt/cm². In pulsed mode the Amplitude during the pulse is displayed. The time-averaged
Amplitude can be obtained by multiplying this value by the Duty Cycle.
