Q

Which of the following statements are precautions for traction

C. Check sensation, reflexes, muscle strength

D. Reduce traction force to 50% or change direction of force

E. Claustrophobia or other psychological aversion to traction

F. All of the above

A

F

18
Q

TRUE OR FALSE: The ff. statements are guidelines for traction

  1. Use small amount of force initially while monitoring patients response to treatment; do manual traction first.
  2. Avoid coughing or sneezing while on traction; increase in intra-abdominal pressure increases intra-discal pressure
  3. Empty bladder; do not have a heavy meal before lumbar traction
A

T

19
Q

TRUE OR FALSE on the position of the patient in the Intermittent lumbar traction (ILT):

If the spine is in flexion, there’s greater separation of anterior structures including the facet joints & intervertebral foramina.

If the spine is in neutral/extension, there’s greater separation of posterior structures including the intervertebral disc spaces

B. both statements are correct
C. only the 1st statement is correct
D. only the 2nd statement is correct

A

B

If the spine is in flexion, there’s greater separation of POSTERIOR structures including the facet joints & intervertebral foramina.

If the spine is in neutral/extension, there’s greater separation of ANTERIOR structures including the intervertebral disc spaces

A

T

23

greater relaxation & lesser EMG activity of paraspinal muscles are observed in prone.

supine flexed position localizes traction to upper lumbar & lower thoracic segment while prone neutral localizes force to lower lumbar segments,

A

TT

24

PT has to observe the traction being applied and the initial reaction of
the patient for a few cycles.

Give means to call you and to stop the traction to make adjustments when needed.

27
Q

modified TRUE OR FALSE:

The maximum posterior elongation of the cervical spine is when there’s 25-35° neck flexion.

In supine, the cervical spine is supported & non- weight bearing, resulting in more patient comfort & muscle relaxation, & greater separation of cervical segments compared in sitting.

A

TT

28
Q

modified TRUE OR FALSE. the ff. are written in the correct documentation format

ICT in supine with neck flexed 25° X 5kg max force; 2kg min force X 8s pull; 8s release X 20mins to dec. muscle spasm.

ILT in supine with hip flexed to 90°, now at 20kg max force; 10kg min force X 8s on-time; 8s off-time X 20 mins to decompress lumbar spine.
