Combination Therapy -
Using the Combo Jack
e Combo Jack provides the ability to combine electrical stimulation from an existing electrotherapy device with the
Dynatron 125 Ultrasound. e existing stimulator device must comply with IEC 601-1 and IEC 601-2-10 (general and
particular standards) requirements. e banana jack accommodates a Combination Lead Wire or requires the use of a
pin-to-banana adapter in order to provide Stim output through the Ultrasound head. e choice of electrotherapy modalities
that can be combined with an Ultrasound treatment depends on the stimulation device being used. Refer to the stimulation
device’s instruction manual for instructions regarding delivering electrotherapy. Dynatronics’ stim devices ae recommended.
Any other stim device used must not exceed the voltage levels of a Dynatronics’ stim device to ensure safety for the patient.
WARNING
• DO NOT use combination therapy for underwater treatment. Placing active electrodes underwater poses a
serious hazard to the patient!
• Use VERY LOW STIM INTENSITY for COMBO treatments.
• Remember to observe all contraindications, warnings, precautions, and usage cautions for BOTH Ultrasound
and Electrical Stimulation therapy when performing combination therapy.
• Since electrical current travels between the electrode and the soundhead during a COMBO treatment, the
electrode should be placed in proximity with the treatment area. Do not place the electrode and soundhead in
positions that will cause current to pass through contraindicated areas.
• Avoid removing the soundhead from the skin surface during “Stim rough Soundhead” treatments as
this may cause a momentary interruption of Stim current which may be uncomfortable to the patient. e
soundhead should remain in full contact of the skin until current output is stopped.
• Be alert for any sign of periosteal (bone) pain.
