Cameron Dressen, Ryan Sanft, and Tyler Kohmetscher Osteoporosis
Background • Skeletal disease that is characterized by low mineral density • Occurs when the formation of new bone doesn’t keep up with the removal of old bone • >10 million Americans older than 50 have this disease and another 34 million are at risk • Normal • -1 to 1 standard deviations of a normal BMD • Osteoporosis • -2.5 to 2.5 standard deviations off of normal BMD
Types • Primary Osteoporosis • Most common type • More common in women than men • Women have lower BMD than men • Postmenopausal women-estrogen decreases • Testosterone decreases in men • Secondary Osteoporosis • Caused by other medical conditions
Types (cont) • OsteogenesisImperfecta • Rare form present at birth • Bones break for no reason • Idiopathic Juvenile Osteoporosis • Ages 8-14or during growth periods • No known cause
Exercise Testing • Considerations • Use bike as alternative to treadmill • Avoid tests that would load the spinal column • Don’t do max tests with patients with severe osteoporosis
Exercise Prescription • Individuals at risk have 1 or more risk factors • Current low bone mass • Age • Female • If at risk use FITT principle to help maintain bone health
Exercise Prescription • Frequency • Weight-bearing 3-5 days/wk • Resistance 2-3 days/wk • Intensity • Moderate intensity (60-80% 1RM) 8-12 reps • High (80-90% 1 RM) 5-6 reps • Time • 30-60 min/day • Type • Weight-bearing- stair climbing, walking, etc • Resistance Exercises
Special Considerations • Generally recommended • Moderate exercise that doesn’t cause pain • Those with osteoporosis AVOID…. • Explosive movement and high-impact loading • Twisting, bending or compression of spine • For elderly prescribe • Stretching • Balance exercises
