Uninvolved
Involved (therapeutically)
Standard wheelchair measurements for proper fit, and average adult size: Seat depth
Subtract 2 inches from buttock to popliteal fold
16 in
Standard wheelchair measurements for proper fit, and average adult size: Seat width
Add 2 inches to widest aspect of butt, hip, thigh
18 inches
Standard wheelchair measurements for proper fit, and average adult size: Back height
Subtract 4 inches from the seat of the chair to floor of the axilla, so it is below the inferior angle of the scapula
16-16.5 inches
Standard wheelchair measurements for proper fit, and average adult size: Armrest height
Add 1 inch from seat of chair to olecranon process when arm flexed at 90.
9 inches
The handgrip of axillary crutches/cane should be at what level when the pt is standing?
Ulnar syloid
Where should axillary crutches be positioned when fitting them to a pt?
6 inches in front, 2 inches lateral
Crutch height should be no more than _____ finger widths from the axilla
3
Lofstrand crutches: proper fit means ____ to ____ of elbow flexion
20-25 with crutches places 6 in in front and 2 in lateral
Hickman catheter: where, what is it used for
Indwelling R atrial catheter, via sup. vena cava. Used for long-term administration of substances into teh venous system such as chemo, nutrition, antibiotics
Swan-Ganz catheter: where, what is it used for
inserted through a vein to a pulmonary artery
The 2 modalities that transfer heat by conversion
Diathermy, U/S
The 3 modalities that transfer heat by radiation
Infrared, Laser, UV light
An area of ___ to ___ cm can be covered in 5-10 minutes for ice massage
10-15
The series of sensations for ice massage
intense cold, burning, aching, analgesia
A cold pack should be applied for ____ min for msk conditions, _____ for spasticity reduction, checked every _____ minutes
20, 30, 10
Cold bath temp should range from ____ to ___ degrees
55-64 F
Hot packs are stored between ____ and _____ deg F
Fluidotherapy
Paraffin
158 and 167
100-118
113-122
Check skin every ____ min for hot pack
5
How many towel layers for hot pack?
6-8
Ultrasound: Effective radiating area vs spatial averaged intensity vs spatial-peak intensity, vs beam nonuniformity ratio
ERA: are of the transducer that transmits energy, is always small than the size of the head.
Spatial averaged intensity: the intensity of the U/S beam averaged over the are of the transducer (Watts/cm2).
Peak: intensity of the beam at its highest point
BNR: ratio between the spatial peak intensity and the spacial averaged intensity, lower is better, usually 5:1 to 6:1, can range from from 2:1 to 8:1
Why would one use a lower duty cycle like 20% for U/S?
For nonthermal effects:
increased cell permeability, increased intracellular calcium levels, facilitation of tissue repair, promotion of normal cell function. Resulting from cavitation (bubbles)
An area ___ to ____ times the size of the transducer typically requires 5 minutes of U/S time
2-3
The most common frequency used for shortwave diathermy is _____MHz
27.12
