neuro9 DTR
Question | Answer |
---|---|
A deep tendon reflex (DTR) | motor response to a sensory stimulation that is used in an assessment to observe the integrity of the nervous system. A DTR elicits a muscle contraction when the muscle's tendon is stimulated. |
DTR Procedures | patient relaxed, muscle slight stretch. reflex hammer taps tendon with an anticipated immediate response. Reflexes can be graded as normal, exaggerated (hyper) or depressed (hypo) or on a scale of 0-4. |
DTR Grading 0 = | no response |
DTR Grading 1+ = | diminished/depressed response |
DTR Grading 2+ = | active normal response |
DTR Grading 3+ = | brisk/exaggerated response |
DTR Grading 4+ = | very brisk/hyperactive; abnormal response |
Biceps tendon - | C5-C6 spinal level Contraction of the biceps muscle |
Brachioradialis tendon - | C5-C6 spinal level- Elbow flexion and/or forearm pronation |
Triceps tendon - | C7-C8 spinal level Elbow extension or contraction of the triceps muscle |
Patellar tendon - | L3-L4 spinal level Knee extension |
Tibialis posterior tendon - | L4-L5 spinal level Plantar flexion/inversion of the foot |
Achilles tendon - | S1-S2 spinal level Plantar flexion of the foot |
