Passive ROM to prevent
positioning changes to prevent
How many times per day should ROM be done?

Isometric exercises
generating tension between two muscles
contra in patients with ICP, htn, CHF

Tx by RICE (rest, ice, compression, elevation)
apply ice 10-20 min every 1-2 hr immediately after injury and for 24-72 hrs after

check circulation to legs
ensure hips are not flexed beyond 90 degrees s
Gout
Arthritis of the joint
caused by high serum levels of uric acid
more common with high protein diets
Osteoporosis
Makes someone more susceptible to fractures
decrease in bone mass
Osteopenia
low bone mass
before osteoporosis
Paget disease
