  • genetic programming
  • nutrition
  • exercise
48

  • diet rich in dark green and deep yellow vegetables
  • dairy products
  • diet low in fried foods and carbonated beverages
49
Q

50
Q

growing pains (non-inflammatory pain syndrome that affects children mainly between the ages of 3 and 12)

51
Q

Describe the pain associate with growing pains (common between ages of 3-12 years old)

A

Usually nonarticular, bilateral, and located in lower extramities

  • occurs late in the day or is nocturnal, waking the child
  • frequently occurs on days of increased physical activity
52
Q

True or false: increased levels of hormones cause increased mobility in the joints.

A

True, particularly the sacroiliac, scrococcygeal, and the pubic symphysis pubis joints. These contribute to noticeable changes in posture.

53
Q

What is the posture change in pregnant women termed?

A

progressive lordosis: shifts weight farther back on the lower extremities and can causelower back pain

54
Q

How might a pregnant woman compensate for lordosis?

A

Anterior flexion of the neck and slumping of the shoulder girdle. This can create nerve pressure and some women have aching, numbness, and weakness in the upper extremities

55
Q

Q

At what age does resorption (loss of bone matrix) exceed deposition (new bone growth)?

A

After 40 years old

57
Q

True or false. Men are more affected by osteoporosis than women.

A

False. Women are more affected than men because of lack of estrogen after menopause; this causes bone loss to accelerate.

58
Q

What are the risk factors for fracture associated with osteoporosis in older adults?

A

A

Kyphosis. Associated changes are a backward head tilt to compensate for the kyphosis, and slight flexion of hips and knees.

60
Q

What are some of the main recommendations related to bone health?

A
  1. Diet (dairy, fish, greens, soy, limit caffeine, onions)
  2. Exercise (3 x 30 minute per week of weight bearing activity)(get 15 minutes sun exposure daily for vitmain D)
  3. Lifestyle (avoid smoking and excessive alcohol intake, seek help for depression)
  4. Medical options (speak to physician about bone density scan needs)
  5. Supplements (May need calcium or vitamin D supplements).
61
Q

True or false. Muscle and joint status are interdependent and should be interpreted together.

True. Same applies in the neuro assessment.

62
Q

What is the most prevalent type of arthritis?

A

osteoarthritis

63
Q

What are the risk factors of osteoarthritis?

A

increasing age, family history, excess weight, and joint injury

64
Q

When does rheumatoid arthritis usually appear and which gender does it affect most?

A
  • 40 - 60 years old
  • females 3x as likely
65
Q

What type of fracture is a serious consequence of falls in older adults and which gender is most susceptible>

A
  • hip fractures; females more susceptible
66
Q

What are typical outcomes of hip fractures?

A
  • loss of mobility and independence
  • financial difficulties
  • increased use of health care studies
  • adults aged 50 and older with hip or vertebral fractures wre more likely to die during the 5-year follow up than were those without fractues
67
Q

What are four recommendations for maintaining back health?

A

1) sitting: limit to 30 minutes at a time then take 1 - 2 minute braks
2) Standing: when stnading for prolonged periods, rest one foot on a low stool to relieve pressure and switch feet every 5 - 15 minutes
3) Lifting: lift close to body, smoothly, no twisting and with legs
4) Lifestyle: exercise and limit abdominal weight

68

A

Inside the joint capsule, such as arthritis. Produces swelling and tenderness around the whole joint, and it limits both active and passive ROM in all planes.

80
Q

What is extra-articular disease?

A

Injury to a specific tendon, ligament or nerve. Produces swelling and tenderness to that one spot in the joint and affects ROM in only certain planes, especially during active (voluntary) motion.

81
Q

What is crepitation?

A

An audible and palpable crunching or grating that accompanies movement. Occurs when articular surfaces in the joint are roughened, as in rheumatoid arthritis.

Q

What does the Ortolani manoeuvre test for and how often should it be done?

Q

What does the Allis test assess?

A

Also used to check for hip dislocation by comparing leg lengths.

A

What system can you use to grade ROM and muscle testing?

A

0 - 5 scale, 0 being no contraction and 5 being full ROM against gravity, full resistance

91
Q

Define strain.

A

Injury to a muscle or the tendons that connect muscles to bones ► Common strains include back and hamstring.

92
