Treatment Connect the patient lead to the output socket of the unit. Attach suitable electrodes to the patient and connect the patient lead to the electrode using the blue and yellow cables provided. The yellow cables are channel A and the blue cables channel B.
Page 41
Electrode Fault Detection When a constant current output is chosen and the unit is operating in 4 or 2 pole interferential mode (also in Russian, diadynamic, sinusoidal, galvanic or Träbert modes for the Interferential 970 unit) the electrode impedance is monitored to ensure that adequate electrode contact is maintained.

S/D Curve (970 only) This mode generates rectangular interrupted galvanic pulses for plotting strength/duration curves. Output is from channel A at constant voltage only. Pressing the S/D Curve button in the Stimulator mode list produces this screen – The start pulse width may be adjusted from 100ms to 1s by repeatedly pressing the Start button and the end pulse width from 10μs to 1ms by repeatedly pressing the ‘End’...
Page 43
The graphic at the bottom of the screen displays the pulse width and the progress bar shows when the pulse occurs. Pulse repetition rate is fixed at 20/min. Once muscle contraction has just been detected press ‘Next’. The first point of the S/D curve will be plotted, and the pulse width will decrement to the next width setting.
Page 44
Electrodes It is recommended that only electrodes supplied by EMS Physio Ltd. are used with the Interferential 960/Multidyne 970. Three sizes of conductive rubber electrodes are available. These are small (70 x 50 mm), medium (100 x 70 mm) or large (130 x 100 mm). Replacement sponge covers are available for each electrode.
Maintenance The electrodes and covers may be disinfected using a 70% v/v aqueous solution of isopropyl alcohol. They are NOT suitable for steam sterilisation or for disinfectants containing sodium hypochlorite. N.B. Isopropyl alcohol is flammable and should be kept away from naked flames.
Appendix A – Overview of treatment modalities Electrotherapy Low-frequency stimulation Diadynamic currents were introduced by Dr. Pierre Bernard. They are various combinations of half and full wave rectified 50 Hz sinewaves. Their therapeutic benefits include pain relief, reduction of swelling and inflammation, increased local circulation, muscle strengthening and re- education.
Page 47
Medium-frequency stimulation Interferential therapy employs medium frequency currents used in 2 or 4- pole configurations to produce a low frequency stimulation effect. Prior to the introduction of interferential therapy in the mid-1950s, low frequency stimulation was used for pain relief, muscle re-education etc. These currents, however, have the disadvantage that normal human skin has a relatively high impedance at such frequencies.

Output Waveforms Interferential 4-pole Channel A Channel B Carrier Frequency Period Frequency Period 2 kHz 2 kHz 500 µs 1.75-2 kHz 572-500 µs 4 kHz 4 kHz 250 µs 3.75-4 kHz 267-250 µs 8 kHz 8 kHz 125 µs 7.75-8 kHz 129-125 µs In constant current mode the maximum output current per channel is 100 mA peak (70 mA rms).
Page 52
Interferential 2-pole The maximum output voltage and current are the same as for Interferential 4-pole operation. Two channels of output are available with independent intensity control. Russian stimulation The burst frequency may be set to be from 1 Hz to 100 Hz. The on and off times are always equal and are from 0.5s (1 Hz burst) to 5 ms (100 Hz burst).
Page 53
TENS Three TENS waveforms are available: pulse period = 1/(repetition rate) TENS burst mode For repetition rates greater than 20 Hz, the TENS output is on for 0.25 s and off for 0.25 s ( 2 Hz burst frequency). For repetition rates less than 20 Hz the on and off times are 5 pulse periods.
Page 54
Diadynamic In diadynamic mode the unit produces six different waveforms. The maximum peak output current is limited to 70 mA. DF - diaphasé fixe The DF waveform is a continuous full wave rectified 50 Hz sinewave. rms current = peak current x 0.707 The maximum rms current is 50 mA.
Page 55
LP - modulé en longues périodes The LP waveform provides an MF signal for 5 seconds. Then over the next 2.5 seconds the other phase of the 50Hz rectified signal is smoothly increased in amplitude to give a DF signal for a further 5 seconds. Finally, the signal returns to MF by smoothly reducing one phase of the rectified signal over the next 2.5 seconds.
Page 56
Sinusoidal In sinusoidal mode, the output is an amplitude-modulated medium frequency (4 kHz) with 50 Hz sinusoidal beat frequency. The amplitude is determined by the output level setting and the surge type and rate. The maximum output is 140 V or 50 mA peak. For a sine wave the peak output or amplitude is equal to the rms output multiplied by √2, or, conversely rms output = peak output x 0.707...
Page 57
Faradic The output in faradic mode is a series of 0.5ms pulses at a repetition rate of 50 Hz with zero dc content. The pulse train is surged in the same way as the sinusoidal output. Galvanic Galvanic mode produces a direct current of up to 70mA or 140V in either a positive, negative or auto-reverse (halfway through the treatment time) electrical polarity.
Page 58
Träbert This mode produces a continuous train of 2ms pulses with a 5 ms interval between each pulse. The pulse repetition rate is therefore approximately 143 Hz. Pos (+), Neg (-), or autorev polarities are selectable. Medi-Wave The Medi-Wave output is a train of differentiated pulses with a pulse width of 6 ms.
Page 59
Output display The Primo Interferential 960/Multidyne 970 display shows the peak current or peak voltage of each output channel depending on whether constant current (CC) or constant voltage (CV) has been selected for the treatment. All information on model, serial number, and month/year of manufacture is located on the rear panel.
