Page 6: Introduction
Velocity = frequency x wavelength Sound will travel faster through media where the molecules are closer together and so the velocity is higher in solids than in liquids, and higher in liquids than in gasses. COMBINATION 850 ISSUE 2... - Page 7 Interferential Therapy The Combination 850 Unit generates medium frequency currents used for 2 and 4-pole interferential therapy. Prior to the introduction of interferential therapy in the mid 1950s, low frequency stimulation was used for pain relief, muscle re-education etc.
- Page 8 The main advantages of such a combination are said to be:- é in localising lesions (especially chronic) ie. diagnostic use. é in ensuring accurate localisation of ultrasound treatment to provide increased accuracy / effectiveness in treating deeper lesions. é in treating trigger points.

- Page 9 In summary, by combining the two treatment modalities, none of the individual effects of the treatments are lost, but the benefit is that lower treatment intensities can be used to achieve the same results, and there are additional benefits in terms of diagnosis and treatment times.

Connect either the 4-way or 2-way patient lead to the interferential output socket. When inserting the plug make sure that it is correctly aligned with the socket. The plug has a locking ring to make sure that it is not disconnected inadvertently. COMBINATION 850 ISSUE 2... -
Page 25: Operating Instructions
Operating Instructions 1. For mains operation, connect the Combination 850 to a suitable mains supply as described in the installation section of this manual. Switch the Combination 850 on using the mains switch on the front panel. The green mains indicator adjacent to the mains switch will light. - Page 26 Pressing the down cursor key again will move the highlight bar to ’Power’. The Combination 850 always displays the temporal-peak spatial-average intensity in watts per square centimetre in the the output section of the display. The display can also show the temporal-peak or the temporal-average power in watts at the bottom of the display.
- Page 27 . If the treatment time is zero or a suitable transducer is not connected to the ultrasound output socket then the Combination 850 will give a short beep. Move the transducer over the treatment site in small circular paths whilst increasing the output to the desired intensity using the ultrasound intensity up key.
- Page 28 The Combination 850 transducers are suitable for treatment using a water bath. This is especially useful when treating areas which are not uniform such as feet or hands. When using a water bath it is advisable to use degassed water (water that has been boiled to remove any air and then allowed to cool).
- Page 29 Form determines the way in which the AMF sweeps between the base and peak frequencies. Three standard forms are available with the Combination 850. The 1|1 form gives 1 second at the base frequency followed by 1 second at the peak frequency.
- Page 30 Always advance the control slowly. If the control is advanced too quickly initially then the Combination 850 will not energise its interferential output and the output display on the LCD will flash. Turn off the interferential output control and try again.
