Tens is unsuitable and should not be used in the following situations.
• Persons suffering from conditions where the circulation is impaired.
• Epilepsy, Heart Condition or any form of Malignancy.
• Patients with poor skin sensation and non-compliant patients who
are emotionally disturbed or have dementia.
• Over metal implants or in conjunction with sleep apnea or heart
monitors.
You should be aware that TENS units provide symptomatic relief
only and are not considered curative.
The degree of pain relief declines in some cases with time, TENS
may have less effect after extended use. To reduce the risk of development
of tolerance, the following measures may be taken:
• Frequent follow-ups.
• Teach the patient to use burst, modulated, and conventional
stimulation.
• Vary electrode placement.
• Vary the frequency
If none of the above are successful discontinue TENS for up to 2
weeks and then resume stimulation.
As with pain-killing medicines, TENS provides temporary pain relief,
which often lasts up to four hours after treatment. Treatment usually
lasts 30-60 minutes, 2-4 times daily.
The time taken to achieve pain relief varies from an immediate effect
up to about an hour. Some patients prefer continuous stimulation
while others prefer intermittent stimulation with different intervals.
Remove the electrodes and discontinue stimulation if you experi-
ence skin irritation or discomfort.
