Medi-Wave set-up (960 and 970) Frequency: Touching this button opens this window:- The frequency may be set from 2 to 60 Hz in 1Hz increments.
  • Page 34 Mode: Normally Medi-Wave stimulation is used in continuous mode - that is with no modulation (none). In addition, burst and surged modes are also available. In burst mode the burst rate is 2 Hz for pulse frequencies greater than 20 Hz and the pulse frequency divided by 10 for frequencies less than 20 Hz.
  • Page 35 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 stimulation list (after Microcurrent) 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 button.

  • Page 39 When running in 4-pole and Interferential 2-pole modes a graphic with a moving cursor at the bottom of the AMF button shows the position in the frequency sweep. When the treatment time reaches zero, a three second alarm is sounded. Note: In soft water areas it may be necessary to add a small amount of bicarbonate of soda to the water used to wet the sponges in order to achieve adequate contact.
  • Page 40 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.

  • Page 41: Maintenance

    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.

  • Page 42: Appendix A - Overview Of Treatment Modality

    Appendix A – overview of treatment modality 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 43 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.

  • Page 48 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 49 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 50 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 51 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 52 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 53 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. Two channels of output are available with independent intensity control Galvanic Galvanic mode produces a direct current of up to 70mA or 140V in either a positive, negative or auto-reverse (half way through the treatment time)
  • Page 54 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. Two channels of output are available with independent intensity control, 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 55 S/D curve The S/D curve mode generates rectangular interrupted galvanic pulses for plotting strength/duration curves. Only channel A is energised in this mode and the peak output voltage is 140V. Output display The 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.
