how many layers of towels between pt & hot pack? how many layers is a terry cloth cover?
-6-8 layers; terry cloth is 4-6 layers
when does a hot pack reach peak heat?
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
treatment temp for paraffin:
125-127 deg F
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
temperature of whirlpool or Hubbard for treatment?
incl for open wounds & PVD
whirlpool : 103-110 deg
open wounds: 92-96
water temp for aquatic therapy =
LOWER for MS /temp sensitivity/PVD
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
contraindications for use of CRYOtherapy:
3. temperature insensitivity
6. paroxysmal cold hemoglobinuria
7. over regenerating peripheral nerves
ice pack temp should be..
ice massage: stages pt will go thru:
cold -> burning -> aching -> numbness
ice massage treatment time?
after spraying vapocoolant , you should..
have pt perform active exercise (also PROM before and during tx)
to achieve thermal effects via US, use which mode?
pulsed US is used when?
nonthermal efx desired ie acute soft tissue injury
to access the superficial layers during US, what depth of penetration should be used?
IF during US a pt expresses periosteal pain, what should you do?
either decrease the intensity OR increase the SA of tx
typical US pulsed duty cycle is..
US treatment intensity ranges:
-LOWER intensity for acute conditions/thin tissue
for phonophoresis, what mode of US should be used?
pulsed 20% , 1-3 w/cm2,
what modality is recommended to aid in healing diabetic ulcers and wounds?
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
for C-spine traction, what is the positioning?
20-30 deg flexion
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
when applying intermittent mechanical compression, after you check the pt's BP what should you do next?
elevate the limb approx 45 deg and abducted 20-70 deg
what should the inflation : deflation ratio be for intermittent mechanical compression?
3 : 1
what should be the max setting for intermittent mechanical compression?
the pt's diastolic BP
treatment time for intermittent mechanical compression for lymphedema?
2 hours (ideal : two 3-hour sessions daily)
rate of motion for CPM = ?
1 to 4 minute cycles
CPM initial ROM setting?
20-40 deg knee flexion (increase by 5-10 deg )
how long can you maintain positioning in a tilt table?
to assist in wound healing, what type of e-stim would you use?
either low voltage continuous OR pulsed high voltage
when treating a would via ES, in the early phases of healing which of the electrodes should be placed over the wound?
CATHODE for bactericidal effect ; once wound is culture free, use the anode for positive effects
conventional TENS parameters:
-pulse rate, pulse duration, mode, duration of treatment
pulse rate: 50-80 pps
pulse duration : 50-100 millisec
Duration : 20-60 min
when applying IONTOPHORESIS, the active electrode should be ---- in comparison to the medicinal ion polarity?
the SAME ie ANODE (+) w lidocaine (+)
3 examples of negative medicinal ions used in iontophoresis =
USE A CATHODE WITH THESE
during iontophoresis, zinc is used for .. and its polarity is..
used for DERMAL ULCERS; (+) so use an ANODE
Russian current (medium frequency) is used for..
muscle strengthening and decreasing ms spasm
