PHT 222 – UNIT – 4 – TENS - QUIZ
TRUE OR FALSE




TENS is the application of E.S. to the skin via surface electrodes to stimulate nerve
(Sensory) fibers primarily for PAIN RELIEF symptomatically.
Nociceptive pathways means (the encoding and processing in the nervous
system of noxious stimuli)
In Acute pain, The signs & symptoms of inflammation are very strongly perceived
which leads to very intense pain.
The signs & symptoms of inflammation is very less – leads to mild pain in certain
activities.
TRUE OR FALSE

Aδ is a Myelinated nerve fiber.

C afferent fiber is an unmyelinated nerve fiber.


Neurotransmitter – Substance “P” is believed to be the neurotransmitter involved at
the synapse between 1st & 2nd order neurons.
The passage of nociceptive information is interrupted along several stages of
ascending nociceptive pathways to produce Neuromodulation of pain.
TRUE OR FALSE

The modulation of pain occurs by Gate control theory (Pre-synaptic inhibition) &
Descending pain suppression
The fundamental – physiological gating mechanism exists in the dorsal horn which may
allow or inhibit the nociceptive to proceed centrally.


It is believed that the input from mechanoreceptor effectively ↓ the excitability of
nociceptor cell to pain generated stimuli.
If pain stimuli is more then the information is passed to the higher centers with out
inhibition.
