Q

Spinal movement

A

Facilitates movement
Separation 1-2mm per intervertebral space - enough to centralize the np
Transient change - coming off of traction everything can go back but feels good while traction on (disc herniation can see sustained effects though)

Q

Effects on bone

A

limited effect

Facilitation of movement may reduce immobilization related to bone density loss

Q

Effects on ligaments

A

Elongating force - if up to 20 minutes can see creep and elongation of ligaments
Proprioceptive effect - use gate control theory to reduce pain

A

most widely supported
Dec central disc pressure
Encourages np to centralize

Q

Parameters - Body position

A

Most often supine but prone is good too for example if you have patient with disc herniation you don’t want to be pulling them into flexion

16
Q

Parameters - Intermittent vs sustained

A

on and off vs a static pull for duration of treatment

17
Q

Parameters - progressive vs regressive

A

Slowly ramp up the pull and regressive is slowly ramp down

18
Q

parameter - Duration of treatment

A

total of how long they will be on traction

19
Q

Assessment of effectiveness

A

Both duringa nd after
Check on the frequently
Kill switch if needed

20
Q

Positional lumbar traction

A

Knees to chest (inc space btw facets)
Childs pose
Traction over a therapy ball
Sidelying with rotation and towel

21
Q

Manual lumbar traction

A

Unilateral leg pull
Segmental lumbar flexion
Assisted sidelying with rotation

22
Q

Mechanical lumbar traction - patient position

A

Neutral spine position is ideal
Prone vs supine depending on dx
Consider patient comfort

23
Q

Mechanical lumbar traction - force

A

65-200 pounds is therapeutic - depends on their body weight though
50% of pt bodyweight

24
Q

Mechanical lumbar traction - intermittent vs sustained

A

Sustained preferred for herniated disc

All other indications PT may choose

25
Q

Mechanical lumbar traction - progressive vs regressive

A

Based on patient comfort

26
Q

Mechanical traction lumbar - duration

A

8 - 30 minutes
Typically start with 8 and then can add time and move up to 15-20 minutes
Need at least 8 minutes of sustained pull to get therapeutic effect

27
Q

Herniated disc - lateral malleolus fracture - what are your parametes

A

Prone
50% of their body weight
Static
8 minutes

28
Q

Manual cervical traction - bilateral vs. unlateral

A

if bilateral problem go bilateral

if unilateral go unilateral

29
Q

Manual cervical traction - force

A

less than 20 pounds

30
Q

Mechanical cervical traction - patient position

A

Supine with neck flexed 20-30 degrees

Force on occiput vs chin (most from occiput) because chin can cause force on TMJ

31
Q

Mechanicalcervical traction - force

A

20-50 pounds is safe

Start with the 7-8 pounds and then can increase it from there to 20/25 pounds

32
Q

Mechanical cervical traction - intermittent vs. static

A

Intermittent with at least 7 seconds on

Intermittent more common for cervical than static

33
Q

Mechanicsl cervical traction - progressive vs regressive steps

A

Patient comfort

34
Q

Mechanical cervical traction - duration

A

20-25 minutes

35
Q

herniated cervical disc btw C4 and C5 - position

A 
Supine
Pull at 20-30 degree angle
Start force at 20 pounds
Use static for disc
could start with 8-10 or 20 depending on if you did manual traction beforehand
