5

2 methods of applying paraffin = ?

1. dip & wrap - dip 6-12 layers of paraffin then wrapped in plastic wrap or wax paper and elevate for 15-20 min
2. dip and immersion: same steps except leave in bath at end

6

treatment temp for paraffin:

125-127 deg F

7

IF putting a pt into a whirlpool with open wounds, what precaution should you take?

1. add disinfectant : ie sodium hypochlorite (dilution of 200 ppm) or chloramine-T (100-200 ppm)
2. utilize standard precautions : gown, goggles, gloves, masks

8

temperature of whirlpool or Hubbard for treatment?
incl for open wounds & PVD

whirlpool : 103-110 deg
Hubbard: 100
PVD: 95-100
open wounds: 92-96

9

water temp for aquatic therapy =

92-98 deg
LOWER for MS /temp sensitivity/PVD

10

what are 2 adverse effects that can occur 2/2 cold?

cold urticaria (severe itching) & facial flush/puffiness of eyelids/respiratory problems
-BOTH 2/2 histamine release

11

contraindications for use of CRYOtherapy:

1. PVD
2. Raynaud's
3. temperature insensitivity
4. urticaria
5. cryoglobulinemia
6. paroxysmal cold hemoglobinuria
7. over regenerating peripheral nerves

12

ice pack temp should be..

0-10 deg

13

ice massage: stages pt will go thru:

cold -> burning -> aching -> numbness

14

ice massage treatment time?

5-10 minutes

15

after spraying vapocoolant , you should..

have pt perform active exercise (also PROM before and during tx)

16

to achieve thermal effects via US, use which mode?

CONTINUOUS

17

pulsed US is used when?

nonthermal efx desired ie acute soft tissue injury

18

to access the superficial layers during US, what depth of penetration should be used?

3 MHz

19

IF during US a pt expresses periosteal pain, what should you do?

either decrease the intensity OR increase the SA of tx

20

typical US pulsed duty cycle is..

20-50 %

21

US treatment intensity ranges:

0.5-3 w/cm2
-LOWER intensity for acute conditions/thin tissue

22

for phonophoresis, what mode of US should be used?

pulsed 20% , 1-3 w/cm2,

23

what modality is recommended to aid in healing diabetic ulcers and wounds?

PULSED DIATHERMY

24

To produce disc distraction in the C-spine, what % of BWT should be used for traction? How about for disc protrusion?

approx 7 % (20-30 lbs)
disc protrusion: 12-15 lbs

25

for C-spine traction, what is the positioning?

20-30 deg flexion

26

what % of BWT should be used for lumbar traction for jt distractin?

50% (60-120 lbs )
-same for reduction of disc protrusion
-5-10 min for herniated disc, 10-30 min for other conditions

elevate the limb approx 45 deg and abducted 20-70 deg

28

what should the inflation : deflation ratio be for intermittent mechanical compression?

3 : 1

29

what should be the max setting for intermittent mechanical compression?

either low voltage continuous OR pulsed high voltage

35

when treating a would via ES, in the early phases of healing which of the electrodes should be placed over the wound?
