Therapeutic Exercise Approach for Osteoporosis Flashcards
week 1
What is osteoporosis?
Systemic, metabolic bone disease characterized by low bone mass, impaired bone quality, and increased susceptibility to low-trauma fractures.
How is osteoporosis diagnosed?
By DEXA (Dual-Energy X-ray Absorptiometry).
How often do osteoporosis fractures occur?
Every 3 seconds.
What does Wolff’s law state?
Bone adapts to mechanical loading.
How does exercise promote bone health?
By inducing loading conditions on the bones, which helps them become stronger.
What are the static weightbearing (WBing) interventions for osteoporosis?
Single Leg Stance (SLS).
What are examples of dynamic WBing - low force exercises?
- Walking
- Dancing
- Tai chi
What are examples of dynamic WBing - high force exercises?
- Standing weightlifting
- Weighted vest stair climbing
- Jogging
- Skipping
- Jumping
- Hopping
- Running
- Dancing
- Vibration platform
What are non-WBing - low force exercises?
Seated progressive low load high repetition resistance training.
What are non-WBing - high force exercises?
Seated progressive high load resistance training (e.g., seated rows).
What is the combination approach for osteoporosis exercise interventions?
More than any one of the exercise approaches.
What is a key takeaway regarding exercise and bone strength?
Exercise strengthens bones.
What types of activities should be included for effective osteoporosis management?
- Lift heavy
- Absorb impact
- Bear weight statically
- Bear weight dynamically
What do impact protocols and resistance training together accomplish?
They can reduce BMD decline at both the femoral neck and lumbar spine.
What are the adapted exercise recommendations for slow BMD decline at the hip and femoral neck?
- Static weight bearing – SLS balance
- Non WBing high force (70-85% 1 RM) progressive resistance strength training alone or in combination with
- Dynamic WB – low force (walking, dancing, tai chi)
What are the adapted exercise recommendations for slow BMD decline at the lumbar spine?
- Dynamic WB - low force (walking, dancing, tai chi)
- Non-WBing High force (70-85% 1 RM) progressive resistance strength training
What are the adapted exercise recommendations for slow BMD decline at both femoral neck and lumbar spine?
- Non WBing high force – 60% 1 RM progressive resistance strength training
- Dynamic WB - high force progressive resistance strength training
- Dynamic WBing high force impact training (jogging, hopping, stair climbing)
What does Healthy Bones Australia suggest for dosing impact training?
50 impacts divided into brief bouts, i.e. 5x10, at intensity of >2-4 x bodyweight, 3x/week or more.
What is essential for managing osteoporosis across the femoral neck and lumbar spine?
Dynamic weight bearing (low and high force) and non-WBing high force.
What are the effects of progressive resistance and impact training on BMD?
Results in slow decline, maintenance, or even increase in BMD.
True or False: Lack of evidence for certain exercise approaches means they are unsafe.
False.
