Electrotherapy & TENS FAQ

Interferential

Can you recommend a basic interferential unit to use in my Physiotherapy practice?
Our range of interferential units include two and four pole interferential as well as a broad range of muscle stimulation waveforms. Our Combo units also offer the additional versatlity of an inbuilt therapeutic ultrasound.

The best way to determine which model is suitable for you, is make a time to view the equipment in our Showroom or organise a demonstration in your rooms. Our experienced Sales team can talk you through what interface would best suit your needs, and the options for accessories and ongoing consumable items.

Do you sell a unit that does not need a trolley, as space is limited?
OPC Health has a range of Mobile units that can be easily transported between sites, weighing less than 3kg, with their own carry bag and optional battery pack if mains power is not availale. If your needs change, a trolley purchased later and your unit easily fitted. If you wish to use a Vacuum electrode system with your Chattanooga Interferential unit, the module must be installed into the Intelect Advanced Therapy Cart.

The Vacuum Electrode Unit attached to my Interferential Unit has stopped working, what should I do?
It is important for the infection control, safety and hygiene of the Practitioner and clients to follow the manufacturer's guidleines for maintenance. Details of the proper maintenance of your Chattanooga Intelect Vacuum system can be found in your Operating Manual, refer to the Troubleshooting section. The problem can be simple as too much water accumulating in the reservoir, and needing to drain out excess fluid. If the unit requires repair or service, a written claim must be submitted to Chattanooga. Contact the distributor the system was purchased from for all Service and Repair issues.

TENS

Why does the TENS feel weaker or less intense than before?
If you are using a battery operated TENS unit, it could be time to replace your battery. Depending on your level of usage, a standard 9V battery will provide up to ten hours of TENS therapy.

It is very important to monitor the electrodes. The conductivity may be altered if there is uneven contact between the electrode and the skin. Body hair, dead skin, and dust can accumulate to the surface of the electrode. Clean the skin surface and and electrode; apply some conductor gel if the electrode is in good condition. If the electrode itself appears torn; it is important to dispose of it, as uneven conductivity can result in a burn.

How often should I change my adhesive electrodes?
Failing to change electrodes, may result in burns and tissue damage. Replace self-adhesive electrodes regularly. Once the contact surface between the electrode and skin is no longer in full contact, the conductivity will be reduced, and additional battery power required. If excess heat is felt in an area, or signs of wear are seen on the electrode, it is essential to change the self adhesive electrode immediately.

Adhesive electrodes are designed for Single Patient use, and should not be shared with other people. A set of electrodes may be used more than once, with a single person. If you are using a TENS unit for personal use, you may need to change the electrodes weekly.

How do I decide what type of electrodes are suitable for me?
OPC Health sells a range of disposable self-adhesive electrodes and reusable rubber electrodes. The type of electrode will depend on the application, duration and frequency of use. Some electrodes are better suited to people with sensitive skin.

Busy physiotherapy practices often treat a number of patients daily, and find the most economical and hygienic option is reusable rubber electrodes with a sponge pocket or insert. Different sizes correlate to the surface area required for treatment. Your choice of electrode may be determined by cost, or comfort. OPC Health recommends consulation with a Health Professional before using any form of electrotherapy treatment outside a Clinic.
