The Basics of Using TENS: Surge Options

Surge (Exercise) Options

This is a feature that allows exact control of Electrical Muscle Exercise - so is only available in the surge mode. [Not available on Analgesic or Analgesic+2 models]

Mode	Recommendation
Contract	Always start at 6 seconds

Relax	Start by setting at least equal to the Contract time (may be set at up to double the contract time to avoid over-exercising, but this is quite a conservative setting).

To increase the vigorousness of the work out:

Increase the contract time
Decrease the relax time
Increase the length of the work out session

Example:

A leg work out may start at 6 seconds contract time and 6 seconds relax time for a session lasting 15 minutes. Over a period of two weeks, the work out may peak at 10 second contractions with 2 seconds rest between each contraction, for a total time of 30 minutes.
