TENS, EMS & Ultrasound Units

Dunbar Medical offers a range of equipment that you can use for electrotherapy treatment, including ultrasound, TENS and EMS units. Below, we give a brief overview of the options available and their respective pros and cons.

Ultrasound Imaging

Ultrasound imaging is based on the use of ultrasound waves. Medical professionals use the technology to “see” internal body structures, often with the objective of finding the cause of disease or injury.

To do this, the operator produces images (known as sonograms) by sending ultrasonic signals into the body. These signals reflect off the issue under examination with different tissues reflecting varying degrees of sound. The ultrasound unit records the results and displays them as images to the operator.

Compared to other prominent methods of medical imaging, ultrasonic imaging has several advantages:

  • It provides images in real-time.
  • Units are usually portable and the operator can usually bring them to the patient.
  • Compared to other forms of imaging, it is substantially lower in cost.
  • It does not use harmful forms of radiation (e.g. x-rays).

Some of the disadvantages of this imaging technique include:

  • There are limits on the field of view.
  • The operator can encounter difficulty imaging structures behind bone and air.
  • It is dependent on the level of skill of the operator.

TENS Therapy

TENS (transcutaneous electrical nerve stimulation) is a form of therapy that uses electricity to stimulate the nerves of the body, usually with the objective of pain treatment.

It differs from EMS (electrical muscle stimulation) therapy which usually has different objectives than pain reduction (see below).

EMS Therapy

Electical Muscle Stimulation (EMS) is a form of therapy that uses electrical signals to elicit muscle contractions. It is notable for having a wide range of potential applications:

  • Strength training for healthy individuals or even for athletes
  • Evaluation of muscular function
  • Rehabilitation of patients suffering partial or complete immobilization.

Dunbar Medical offers all 3 types of units as well as combination units that offer dual functionalities (usually ultrasound/EMS units). Please contact us to discuss how these units can support your goal of successful treatment outcomes for your patients.
