Amplitude
Amplitude is the intensity or strength of the stimulation. It is measured in milliamps. It ranges from 50 to
80 mA. The best units today offer up to 100 mA.
Steps of intensity control
You can find in the market normal stimulators that only have 8-12 steps of intensity control. You should
look for the units that offer 100 steps of intensity control from 1 to 100mA, 1mA each step for precise
adjustment of intensity level.
Dual Channel
There are Analog Tens unit available with dual channel. Here dual channel means, the unit will allow up
to four electrodes at once. Each channel is designed to connect to a lead wire that splits for 2 pad
attachment.
Modulation and burst mode
The TENS Unit Function modes can be burst, normal, modulation. Modulation mode differs the
treatment cycle so that nerves don't acclimate to the stimulation. It they adapt, it will decrease the
effectiveness.
