Definition of mobility - correct answer ✔✔- state or quality of being mobile or movable

• necessary to perform ADL -includes gross and fine motor -coordination how mobility depend on concepts we learned ie. cogntion - correct answer ✔✔Mobility is dependent on the synchronized efforts of the musculoskeletal and nervous systems as well as adequate oxygenation, perfusion, and cognition. can someone with immobile arms be mobile - correct answer ✔✔yes, mobility can refer to a specific body part or entire body. t or f mobility changes can be temporary - correct answer ✔✔yes. ie. broken arms can be healed scope of mobility - correct answer ✔✔-full/independent mobility -partial or impaired -immobility under what conditions might someone have partial mobility - correct answer ✔✔- injuries- bone fracture -infection or diseases (neurological or musculoskeletal disorder, obesity)
• surgery -pain -depression -aging -sedentary lifestyle -lack of nutrients T or F immobility is beneficial sometimes - correct answer ✔✔T, in conditions that requires rest and recovery- when we have the flu

explain compact bone - correct answer ✔✔aka cortical bone

• strong and dense -composed of structural units called osteons
• covers spongey bone spongey bone - correct answer ✔✔aka trabecular or cancellous
• light and porous
• contains lattice shapes meshwork called trabeculae contains spaces that are filled with blood forming tissue, called red marrow bone remodelling and its purpose - correct answer ✔✔process of bone resorption (broken down) and relaced by new bone (bone deposition)
• maintain and repair bones
• adaptation to stress on bones. ie lifting weights
• mineral regulation since bones hold minerals needed by the body in which part does bone remodelling occur - correct answer ✔✔spongey bone
• occurs in the outter surface of trabecula compact bone
• occurs in the central canal of osteon explain the steps of bone remodelling - correct answer ✔✔1. RESORPTION Osteoclasts attach to the old bone surface and remove bone matrix

2. REVERSAL basically prepping the site for osteoblast
3. FORMATION osteoblasts secrete osteoid (unmineralized bone) and some osteoblast differentiate into osteocytes (cells that maintain bone tissue)
4. MINERALIZATION Osteoblasts deposit minerals in the osteoids to make firm bones define osteoporosis - correct answer ✔✔A skeletal disorder characterized by decreased bone density predisposing a person to increased risk of fracture.

• imbalance in bone remodelling: resorption exceeds deposition Non-modifiable risk factors of osteoporosis - correct answer ✔✔age, female, genetics (small body frame), family history, Race (asians, some european caucasians) modifiable risk of osteoporosis - correct answer ✔✔peak bone mass- start building strong bones in early life makes it less likely to develop lack of calcium or vitamin d (lack of sun) physical inactivity hormone imbalance (hyperparathyroidism) medications- glucocorticoids alcohol smoking what happens after peak bone mass - correct answer ✔✔bone resorption slowly exceeds bone deposition
• bones become weaker and more brittle esp in women When is peak bone mass achieved? - correct answer ✔✔by age 30 what influences peak bone mass - correct answer ✔✔genetics females- smaller bone hormones nutrition vit d and calcium physical activity- weight bearing exercise lifestyle- non smoker and non excessive alcohol and non smoker what hormones maintain Ca levels - correct answer ✔✔parathyroid hormone PTH- hyperparathyroidism can cause excessive bone loss and activated vitamin D aka calcitrol

detection osteoporosis - correct answer ✔✔assess BMD (bone mineral density) by DXA scan T score:0-2.5 normal, -1 osteopenia, -2.5 osteoporosis purpose of early detection of osteoporosis - correct answer ✔✔detect before fracture determine rate of bone loss monitors response to therapy components of focuses mobility assessment - correct answer ✔✔client or health history data physical exam diagnostic test- T score BMD interventions for mobility - correct answer ✔✔-assistive deivce and protective equipment

• CDM
• education -enviro modification- tripping hazard -exercise program
• med review and modification
• nutrition and supplement
• vision referral and correction
