How would you describe DTR?

DTR is an acronym that means define the relationship. Used in chat and texting, it implies a critical point in a relationship in which one person wants clear answers from the other.

Why is assessing deep tendon reflexes important?

The DTR is used to assess the integrity of the motor system. They also provide information on the condition of upper and lower motor neurons. If the lesion or injury involves the upper motor neuron (brain, brainstem, or spinal cord), an increased reflex will be present.

What are the five reflexes most commonly assessed?

Reflexes tested include the following:

  • Biceps (innervated by C5 and C6)
  • Radial brachialis (by C6)
  • Triceps (by C7)
  • Distal finger flexors (by C8)
  • Quadriceps knee jerk (by L4)
  • Ankle jerk (by S1)
  • Jaw jerk (by the 5th cranial nerve)

What do abnormal reflexes indicate?

When reflex responses are absent this could be a clue that the spinal cord, nerve root, peripheral nerve, or muscle has been damaged. When reflex response is abnormal, it may be due to the disruption of the sensory (feeling) or motor (movement) nerves or both.

What are the 6 deep tendon reflexes?

After obtaining the reflex on one side, always go immediately to the opposite side for the same reflex so that you can compare them.

  • Jaw Jerk. Place the tip of your index finger on a relaxed jaw, one that is about one-third open.
  • Biceps Reflex.
  • Triceps Reflex.
  • Brachioradialis Reflex.
  • Finger Jerk.
  • Knee Jerk.
  • Ankle Jerk.

What do deep tendon reflexes assess?

A stretch reflex is an involuntary reaction of a muscle to being passively stretched by percussion of the tendon. Although the reflex has a sensory and motor component, deep tendon reflex testing primarily assesses the integrity of the motor system. This reflex provides information on upper and lower motor neurons.

What do reflexes indicate?

A reflex is an involuntary and nearly instantaneous movement in response to a stimulus. The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc. Reflex arcs act on an impulse before that impulse reaches the brain.

What is normal deep tendon reflexes?

By convention the deep tendon reflexes are graded as follows: 0 = no response; always abnormal. 1+ = a slight but definitely present response; may or may not be normal. 2+ = a brisk response; normal.
