Choosing a Digital TENS Unit or Analog Tens Unit

tens-unitShould you choose a digital tens unit or an analog tens unit?  What are the differences between these two types of tens units?  Tens units come in two basic types either analog like the tens 3000 or digital like the tens 7000 . Depending on the type of tens unit you choose they all use the basic components to control pain.  The three things you need to look at are the pulse rate, width, and amplitude. 

The pulse rate also known as Hertz (Hz), P.R. or Pulses Per Second (pps), or  Frequency of a tens unit can range from 1-250 HZ depending on the tens unit model you choose.  The Pulse Rate is important because different frequency settings target different nerve groups, and the setting you choose will determine if the Tens unit wil work for the condition you are experiencing.

The pulse width is also known as either PW, Pulse Duration, or Microseconds (US).  Usually the pulse width is measured in very small intervals known as microseconds.  This typically ranges on Tens units from 1-250 uS.  The higher the pulse width the more aggressive the electric stimulation feels.

The tens amplitude also know as Milliamps (mA) or Intensity is the amperage or wattage used so that the patient can feel the Tens sensation.  Most portable Tens units range from 0-105 mA.  Basically the higher you turn the tens unit up.  The more you feel the stronger tens current.

An analog tens unit (Tens 3000) is very simple to use.  You basically turn knobs instead of pushing buttons on a digital screen.  This type of unit may be preferred by individuals not comfortable with using computers.

A digital tens unit (Tens 7000) is different from an anlog tens unit in only it has a digital screen in which you touch the screen to change all of your settings.  As far as the Pulse rate, width and amplitude that would depend on which unit you choose.
