chap 7 Flashcards
flexibility referes to the
amount of ROM about a joint or multiple joint at any age
objectives of flexibility training
- Describe the age-associated changes in joint and muscle flexibility
- Identify the critical ranges of joint flexibility for the performance of basic ADLs
- Describe the benefits of flexibility training for daily function
- Identify the 2 types of stretching techniques and when to use them in an exercise session
T/F Flexibility exercises will improve joint ROM at any age
T
The greatest decline in ROM with age is observed in:
spinal extension
what is ROM
Total excursion possible at a joint from the beginning of movement to the end of it
joint ROM decrease from age
20-70
T/F rate of decline is joint specific
T
spinal, hip extension and knee flexion will decline any how munch %
spinal extension 50%, hip extension 20%, knee flexion 2%
why is there only a 2% loss of knee flexion
walking
On avg, is the ↓ROM greater in lower or upper extremity?
lower
H/S flexibility decrease in both gender by +- _% per decade

what is the clinical definition of joint stiffness
Sensation of difficulty moving a joint or the apparent loss of ROM. It often accompanies joint pain and swelling
what is one of the most common complaints of OA
joint stiffness
what factors contribute to stiffness in OA
- with age: decrease muscle mass + increase connective tissue surrounding and within muscle
- connective tissues involved in mobility
- with age change in the chemical composition of the connective tissue matrix and collage
- breakdown of articular surfaces in the weight-bearing joint
Is pain directly coming from the breakdown of articular cartilage?
No pain receptor are located in connective tissues + bone
by the age of 75 years: _% of OA have osteoarthritic change
85
is putting on clothes a BADL or an IADL
BADL
Functional consequence of loss of flexibility can greatly affect ADL’s
- getting out of care (SUV)
- stepping off or. on a curb
- bending down to pick something up
- putting on clothes
Increase in number of functional limitations leads to
loss of independence
what are the de BADLS
consist of self-care tasks: DEATH -> dressing/bathing, eating, ambulating, toiletting, hygiene
what are the IADL
SHAFT-> shopping, housekeeping, accounting, food prep/meds, telephone transportation
IADLs are not necessary for_, but they let an individual live _ in a community:
fundamental functioning, live independently
When OA improve flexibility, they typically improve on
muscular strength
how does ganging flexibility help OA improve strength
Effort spent to gain ROM is sufficient to challenge the surrounding musculature and slightly ↑ strength
Increasing joint’s ROM may release the muscles to such an extent that they can be used more readily and more efficiently
