DTRs Flashcards
Reflexes are an__________________ response ( predictable response is what we are looking for )
involuntary, stereotyped
Reflexes are a unit of ____________ and _____________ function.
sensory (afferent)
motor (efferent)
Reflexes depend on ?
Intact sensory nerve fibers
Functional synapses in spinal cord
Intact motor nerve fibers
Functional neuromuscular junctions
Competent muscle fibers
DTRs helpful in ?
Can help to localize a lesion
Correlate with motor and sensory findings
DTR: Ankle (Achilles) ?
S1
DTR: Knee (Patellar) ?
L 2, 3, 4
DTR: Supinator (Brachioradialis) ?
C 5, 6
DTR: Biceps ?
C 5, 6
DTR: Triceps ?
C 6, 7
Cutaneous Reflexes: Abdominal – upper ?
T 8, 9, 10
Cutaneous Reflexes: Abdominal – Lower ?
T 10, 11, 12
Cutaneous Reflexes: Plantar (Babinski) ?
L5, S1
Cutaneous Reflexes: Anal ?
S 2, 3, 4
DTR: To elicit a reflex ?
Patient must be relaxed!
Strike briskly with wrist movement
Patient can be supine or sitting for all
**the patient need to be completely relaxed
hit hard enough to get a response ( same strength on each side to elect a reflex)
pointed end for smaller areas and bigger end for bigger area **
DTR: Response is affected by your force ?
Use as little force as needed to elicit a response
Compare bilaterally
Rate DTR’s on ______ scale
0-4/4
**pulse 0-3
strength 0-5 ( 5/5 is NL)
reflex 0-4
some people just have really bad reflexes and it can be normal **
DTR: 0/4 ?
absent, areflexia
DTR: 1/4 ?
low normal, hyporeflexia
DTR: 2/4 ?
average, NORMAL
DTR: 3/4 ?
above average, +/- assoc. with disease
DTR: 4/4 ?
very brisk, hyperactive, with clonus
(rhythmic oscillations) hyperreflexia
DTR: Use _________ for barely detectable response
reinforcement
**distracted to improve results **
DTR: Isometric contraction of other muscles: UE ?
clench teeth
DTR: Isometric contraction of other muscles: LE ?
lock fingers and pull hands
