Test- Disorders

  1. ALS (Amyotrophic Lateral Sclerosis)
    -Affects both the motor cortex of the brain and the motor neurons associated with voluntary muscle

    • –Degenerative:
    • 100% fatal
    • Muscle of chest no longer receive impulse to contract/expand ~ makes breathing difficult

    • –Symptoms show up at 50+
    • Death in 2-3 yrs after symptoms display

    (Stephen Hawking)
  2. Polio
    • –Viral disease caused by direct exposure; highly contagious
    • Inflammation & destruction of spinal neurons

    • –Incubation time (5-35+ days)
    • Mild cold symptoms (diarrhea, vomiting, headache)
    • Severe cold symptoms (increased fever, accompanied by acute muscle pains or inability to lift legs or head when lying down

    • –Treatments
    • Vaccine – developed in the 1950s by Dr. Jonas Salk
  3. Muscular Dystrophy
    • –Genetic disorder
    • Dystrophin absent in the cytoskeleton of the muscle fiber

    • -Degenerative
    • Can affect adults, however most severe forms appear early in life

    • -Results in loss of function (weakness & fatigue)
    • Atrophy or wasting

    • -No cure
    • P/T to control symptoms
    • Use of mobility assistance devices
    • MUST remain active
  4. Osteoporosis
    Overactive osteoclasts remove calcium from bone.

    Spaces and canals appear, weakening bones.
  5. Rickets
    Vitamin D deficiency

    Characterized by bowed legs
  6. Scoliosis
    Lateral bend of the vertebral column
  7. Spina Bifida
    Vertebrae fail to join at the midline during development
  8. Osteoarthritis
    Degenerative deterioration of articular cartilage & spur formation usually 60+
  9. Gouty arthritis
    Sodium urate crystals deposited in articular cartilage - destroys join tissue
  10. Rheumatoid arthritis
    • Degenerative autoimmune disease
    • Immune system attacks joint tissue
    • Inflammation of synovial membrane
    • Usually age 20-50

    Meds to reduce pain, anti-inflammatories, slow progression of disease
  11. Lyme Disease
    Bacteria carried by a tick

    Causes stiffness, fever, chills, nausea, arthritis-like symptoms
  12. Capral Tunnel syndrome
    Pressure on the median nerve as it passes through the carpel tunnel in wrist

  13. Flatfooted
    Weakened ligaments & tendons of foot

    Can't support weight well for long periods of walking
