24
Q

If a traction table is able to split, how much is the split treatment table co-efficient of friction?

25
What are the indications for traction?
- Stretch of facet joint capsule - Increase intervertebral foramina space - More space for spinal nerve root - Decreased inflammation - Decrease pain - Muscle elongation - Muscle relaxation - Decreased nerve pressure - Gate mechanism with intermittent traction - Improve blood supply to discs and tissue - Promote negative pressure on disc
26
What are the contraindications for traction?
SOUR JARS - Symptoms worsen/peripheralize - Osteoporosis - Uncontrolled hypertension - Recent spinal fracture - Joint hypermobility - RA, Down syndrome, Marfan syndrome, pregnancy - Acute inflammation/injury - Recent spinal surgery - Spinal cord pressure
27
What are the angles of pull for lumbar traction?
- Anterior - Posterior - Unilateral/Neutral
28
Which angle of pull do you want for traction when you are trying to creat a posterior pelvic tilt?
Posterior angle of pull
29
What are the only angles of pull appropriate for lumbar disc hernation pt.s during traction?
Anterior or neutral
30
What are the parameters for angle of pull for C-Spine Traction?
- AO joint = 0 deg | - C2-C7 = 25-35 deg
31
What are the parameters for poundage of C-Spine Traction?
- Begin with 8-10 lbs | - Progress to 20-30 lbs max
32
What are the parameters for poundage of L-Spine Traction?
- Begin with 25% of body weight (30-45 lbs) | - Progress to 60% of body weight max
33
For what reasons are Static or Intermittent Traction used for both C & L-Spine?
- Static: - Best for disc herniation - Intermittent: - Long is best when static is not tolerated or for muscle elongation (60:20) - Short is best for facet/DDD/DJD/spasm (1:1)
34
What are the parameters for time during both C & L-Spine Traction?
- First time: 5-10 mins - Static: 5-10 mins - Intermittent: 20-30 mins

- C-spine or L-Spine traction - Pt. position - Angle of pull - Static/Intermittent - Poundage - Rx Time
36
What are the different types of Edema?
- Local edema - General edema - Lymphedema
37
Describe Local Edema
- Unilateral or bilateral - Caused by trauma, infection, or obstruction - Can happen post mastectomy
38
Describe General Edema
- Bilateral LEs, groin, abdomen, may be total body edema - Systemic (relating to a system rather than a particular part - Caused by chronic illness- cardiac disease, kidney failure, liver disease
39
Describe Lymphedema
- Painless edema of one or both UEs or LEs | - Caused by impairment of lymphatic drainage
40
What is the Role of Muscle Spindle in regards to Tone?
Stretching muscle facilitates/contraction in the agonist and inhibits the antagonist
41
What is the Role of GTO in regards to Tone?
Applying extra pressure to the tendon of an agonist will signal antagonist to contract and counteract agonist
42
What are the Roles of Cutaneous Receptors?
To detect Temperature, Pressure, Pain, Touch, and Texture
43
What are some techniques which can be applied to Cutaneous Receptors to increase Tone?
- Quick light touch - Brushing - Quick icing

49
Describe a Stage I wound

50
Describe a Stage II wound
- Epidermal Wound | - Partial thickness involving epidermis and/or dermis
51
Describe a Stage III wound
- Dermal Wound | - Full thickness involving dermis and to, but not through the fascia
52
Describe a Stage IV wound
- Dermal Wound | - Full thickness involving tissue necrosis or damage to muscle or bone
53
What is the Gate Theory?
- Lg diameter A beta fibers increase activity in dorsal horn of spinal column, close the gate, and decrease pain perception - Sm diameter A delta & C fibers decrease activity in dorsal horn of spinal columc, open the gate, and increase pain perception
54
What is the Gate Mechanism?
Thermoreceptors (heat/cold), Mechanoreceptors (rubbing/E-stim) can reduce pain, therefore reducing spasm/musle tension
55
What are the different sensory fibers and how are they described?
-A-Delta Fibers: -Nocioceptor -Myelinated (faster transmission) -Evoke sharp, pricking sensation -C-Fibers: -Nocioceptor -Unmyelinated (slower transmission) -Longer lasting -Evoke burning sensation that is poorly localized -A-Beta Fibers: Non-Nocioceptor
56
What are the different Spinal Pathways and how are they described?
Ascending Pathways - Spinothalamic: - Impulses travel to thalamus and then to somatosensory cortex - Responsible for sharp, discriminative, localized sensations - Spinoreticulothalamic: - Impulses travels to reticular formation to thalamus and limbic system - Diffuse and visceral pain perception Descending Pathways - Motor tracts - Endogenous opiates released from higher centers - Examples: enkephalins, endorphins, serotonin, dopamine - Stimulated by systemic pain, intense exercise, laughter, meditation, relaxation, acupuncture, E-stim
