Q

NMES- low rate vs. high rate

A

Low rate – twitch – used over motor pts, low rate, high width, endogenous opiates, good for chronic pain, tx time – 30-45 min
High rate – sensory analgesia – multiple electrode placements, high rate, low width, gating, more comfortable for long applications, best for acute pain

Q

the purpose of nodes of ranvier

A

The action potential travels from one location in the cell to another, but ion flow across the membrane occurs only at the nodes of Ranvier. As a result, the action potential signal jumps along the axon, from node to node, rather than propagating smoothly, as they do in axons that lack a myelin sheath.

Q

hydrotherapy- deep water excdercise

A

Patient’s feet cannot touch the bottom
Open chain exs
Depth at least 5’6”
Patient must use buoyancy assist devices
Water should be tepid, since treatment times approach 45 min
Great medium for pregnancy
Water immersion – lowers resting heart rate. This is good for pregnant women with back pain as land based exercise has been shown to raise the heart rate of the fetus.

28
Q

disorders for why traction could be used

A

Disc protrusions
Lateral stenosis (pinched nerves)

Q

traction- intermittent vs. static hold

A

Intermittent (the rest period)
Static hold is better for chronic holds

facet issues benefit from long intermittent

30
Q

lumbar traction-angles of pull

A

45-60 deg of flexion will cause laxity at the L5-S1 level
60-75 deg – laxity at L4-5
And 75-90 deg at the L3-4 (traction boulster)

31
Q

contraindications for traction

A
Spinal infections – meningitis
RA
Osteoporosis
Spinal CA (cancer)
Spinal cord pressure
Recent fracture
Harrington rods? (very rare)
32
Q

define TENS

transcutaneous electrical nerve stim – pain management through skin electrodes

33
Q

define IFC

A

Interferential Current – 4 electrodes. Used for pain. 2 currents – interfering. (most liked by patients)

34
Q

define NMES

A

neuromuscular electrical stim – stimulating innervated mm to restore function. Includes strengthening and muscle re-ed

35

41
Q

most tens and nmes are what type of wave?

A

biphasic

A

5mA**

45
Q

3 categories of peripheral nerves

A

: A (biggest, afferent and efferent and myelinated); B (same as A but smaller); C – unmyelinated and small – these are pain (visceral) and cutaneous sensation. (don’t move quickly) some sensations don’t want to relay quickly

46
