24
Q

The proper range for cervical traction is x-x degrees of cervical flexion

proper lbs/force for cervical traction?

A

20-30 deg

force of 20 pounds

25
Q

Biphasic electrical stimulation with two electrodes placed on the motor points; 2 second ramp time and a duty cycle of 10 seconds on, 30 seconds off.

What goal is being met?

A

muscle reeducation.

26
Q

1 sec ramp time and duty cycle of 10 seconds on, 10 seconds off

what goal is being met?

A

treatment of muscle spasms

27
Q

x-phasic waveforms are most appropriate for wound healing.

A

Mono

28
Q

Direct Current (DC) or Galvanic

features?

A

Continuous unidirectional flow of charged particles with a duration of at least 1 second.

One electrode is always the anode (+) and one is always the cathode (-) for the entire event.

There is a build-up of charge since it is moving in one direction causing a strong chemical effect on the tissue under the electrode

29
Q

Alternating Current (AC)

features?

A

bidirectional flow of charged particles changing direction at least once per second.

Electrodes continuously changes polarity each cycle, therefore no build-up of charge under the electrodes

Often used in interferential or Russian commercial stimulators

30
Q

Pulsed Current (pulsed)

features?

A

Can be unidirectional (like DC) or bidirectional (like AC)

Flow of charged particles stops periodically for less than 1 second before the next event

Pulses can occur individually or in a series

31
Q

Considerations for Adposity and Estim?

A

adipose (fat) is a resistor, causing increased impedance

intensity required to reach MM may not be tolerated by the patient, rendering electrical stimulation an inappropriate modality for that patient

32
Q

Electrical stimulation AND ultrasound would not be appropriate for the areas of the body with ?

A

little depth and little soft tissue between the skin and bone (knee joint, elbow joint, spine, etc.)

33
Q

what modality can help to reduce scar tissue formation

A

ice massage

34
Q

High voltage pulsed current is typically utilized in treatment of ?

A

pressure ulcers

35
Q

x increases tissue extensibility which will help facilitate passive range of motion

A

heat

36
Q

Traction in WHAT POSITION is the most effective position in which to perform spinal traction, as it facilitates relaxation of the low back musculature to allow for true traction

A

hooklying (knees raised)

37
Q

What time range will allow a cold pack to have an effect on edema and pain?

A

10-20 minutes

38
Q

Cryotherapy should be applied for no more than ?? minutes at a time and at least one hour between sessions.

A

20

39
Q

The stages of cryotherapy are typically -

A

CBAAN

intense cold, burning, aching, analgesia, and numbness.

40
Q

Effect of heat on mm strength?

A

superficial heat can decrease strength for a period of time (about 30 minutes) following a heat session

41
Q

pairing an electrical stimulation with a functional activity = ?

eg; Estim to contraction during gait ex

A

FES

Function Electrical Stim

42
Q

Conduction = direct contact heat transfer

examples?

A

Hp, CP, ice massage parrafin, cryocuff

43
Q

whirlpool is an example of what kind of energy transfer?

A

Convection - gain or loss of heat d/t water moving in constant motion across body

44
Q

Ultrasound and Diathermy utilize what mode of energy transfer?

A

Conversion - nonthermal energy (mechanical) is absorbed into tissue and transformed into heat

45
Q

Radiation is heat transfer via what?

A

light/photons via temerpature differential at impact surface

46
Q

What is an example of evaporation for theraputic modality?

A

vapocoolant spray

47
Q

Theraputic effects of cold?

A

decrease edema, blood flow (vasoconstriction)
decrease nerve conduction, mm tone
increase pain threshold

48
Q

Perform ice massage for how long?

A

5-10 mins max

stop if rash, wheals - red or dark pink OK

49
Q

A cold bath req what temperature? How long to place body part?

A

55-65 deg

15-20 mins

50
Q

Temperature for parrafin? how many dips? time to leave on hands in bag vs in bath?

A

110-120 deg

6-10 dips

leave in bag for 5-10 mins
leave in bath (off) after dips up to 20 mins

51
Q

height for infrared lamp above target tissue? Towels?

A

20 in

towels masking nontargeted areas

52
Q

Edema Management (subacute/chronic)

A

NMES; AC/Biphasic/Russian to tetanic muscle contraction
50% duty cycle/ 1:1 on off ratio
x 10-20 minutes

logic = mm pump of lymph, rhythmic assist of venous return

53
Q

Copper Sulfate, Magnesium Sulfate, Zinc Oxide, and Lidocaine have what charge/polarity for iontophoresis?

A

POSITIVE

put it on the electrode that has the same electrical charge as the medication does so it will repel and push through the skin***

54
Q

Where to put medication for ionto?

A

put it on the electrode that has the same electrical charge as the medication does so it will repel and push through the skin***

55
Q

Dexamethasone, iodine, calcium chloride = what polarity?

A

NEGATIVE
