Titration

The incremental adjustment of a medication in subsequent doses until a desired effect is achieved.

Titration to relief

A gradual increase in pain medication dosage until the highest pain relief is obtained, making the pain as tolerable as possible while minimizing short- and long-term negative effects.

Tolerance

A state of adaptation in which repeated exposure to a medication induces changes that diminish one or more of the medication’s effects over time.

Transcutaneous electrical nerve stimulation (TENS)

Electrical stimulation of the sensory myelinated A-beta fibers to produce a pleasant, gentle tingling sensation. Current is delivered to the skin via electrodes, usually placed proximal to the painful area. The patient is able to control the amplitude or intensity of the impulse, the frequency and the pulse width.

Trigeminal neuralgia (tic douloureux)

A chronic pain condition characterized by severe pain, usually stabbing or like an electric shock in the distribution of the trigeminal nerve. Pain can last from seconds to minutes, is almost always unilateral, and can be triggered by brushing teeth, face washing or a cold wind. On physical examination, there are no sensory defects. Between the episodes of pain, there is no background discomfort.
