    InTerferenTIal and PremodulaTed modalITy InformaTIon Interferential and Premodulated Modality Information Interferential (Quadpolar) Therapy Interferential therapy uses four electrodes to deliver two currents, one current with a constant frequency of 4000 Hz and the other current with a variable frequency of 4000 to 4150 Hz. The paths of these two currents cross resulting in a “beat” that produces the therapeutic frequency at the treatment site.

The Dynatron 25 Series 525 and 625 do not offer the Ultrasound feature. Ultrasound therapy channels sound waves through muscle, nerve, bone, and connective tissue to aid in reducing pain, muscle spasms, and joint contractures.

    ulTrasound InsTruCTIons Make sure a soundhead is firmly plugged into the device before turning the device on. When changing to a different size soundhead, turn the machine off first, remove the soundhead, plug in the desired soundhead, then turn the machine on again.

  • Page 55: Head Temperature Hot Display

    ulTrasound InsTruCTIons During any Ultrasound treatment the soundhead should be moved continuously, covering an area approximately two to four times the size of the soundhead. The full surface of the soundhead should maintain in contact with the patient’s skin (except with underwater treatments).

  • Page 59: Ultrasound Modality Information

    Modality Information For Dynatron 825, and 925 users only. The Dynatron 525 and 625 do not offer the Ultrasound feature. Ultrasound, by its very nature, has the ability to irritate the patient’s skin. While the benefits of Ultrasound far outweigh any disadvantages, certain precautions should be observed to assure maximum safety and comfort for your patients.

  • Page 60: Penetration Of Ultrasound Waves

    ulTrasound modalITy InformaTIon The selection of the appropriate soundhead is key to the success of the treatment and is based on the size of the area to be treated. Ultrasound treatments should be kept specific to the tissue involved in pathology. A good guideline is 2 to 4 times the size of the soundhead.

  • Page 61: Types Of Delivery

    ulTrasound modalITy InformaTIon Types of Delivery Ultrasound can be delivered in four different ways. You will likely only see two of the four methods in clinical practice. 1. Direct Contact Movable. Here the soundhead is placed in direct contact with the patient. A coupling agent is used between soundhead and the patient’s skin.

  • Page 62: Frequency Of Treatment

    ulTrasound modalITy InformaTIon 4. Use a little lower intensity for the first treatment to gauge response. 5. Patient feedback is key. A treatment should feel warm, but the patient should never feel heat, pain, stabbing, pricking or dull ache. Acute Conditions: ........0.1 – 0.5 W/cm (no appreciable thermal effect).

    ulTrasound Problem solVIng Ultrasound Problem Solving Whirlpool Treatments If you are treating in a whirlpool, you may find the temperature reaches high enough to read approximately 103˚F, causing the overheated soundhead caution to appear in the Treatment Display Screen. This is only a cautionary warning to let you know that the soundhead is approaching the temperature limit.

  • Page 65: No Soundhead

    Check to be sure the soundhead has not become disconnected from the machine. The soundhead should be firmly plugged into its port. Only Dynatronics soundheads may be used with this device. If the soundhead has been dropped, it may be damaged. If the device operates normally with one soundhead, but not with another, the problem may be a damaged soundhead and you must contact Dynatronics Customer Service.
