  1. What are the 2 types of tissue disruption?
    • 1. Mechanical
    • 2. Neurological
  2. Types of mechanical disruption:
    • 1. Compression
    • 2. Tension
    • 3. Shear
    • 4. Torsion
    • 5. Bending
  3. Shear:
    Sliding force applied btw 2 TS tat generates excess friction
  4. Torsion:
    Rotary (twisting) force applied to TS
  5. Neurological disruption:
    Errors in signal processing within CNS and PNS
  6. Contractile:
    Actively engaged to create movement > muscles, tendons
  7. Non-contractile:
    Lack ability to produce movement > jt capsule, ligament, bursa, cartilage, fascia, dura mater, nerves
  8. Muscle > function:
    • - Maintain posture
    • - Create movement
    • - Slow/stop mvmt/provide sensory feedback about body's position in space (proprioception)
  9. Strain:
    MS fibers are torn w/in TS due to excessive tensile stress
  10. Tendons > function:
    Transmit contractile force of associated MS to bone
  11. Tendons > Issues:
    • - Tendonitis/tendinosis(chronic): abnormal condition of tendon
    • - Tenosynovitis: inflammation and/or irritation btw tendon & synovial sheath
    • - Avulsion: tendon forcibly torn away from bone attachment site
  12. Ligaments > function:
    Connect adjacent bones & establish stability in skeletal struc
  13. Ligaments > Issues:
    • Sprain - accute overload tensile stress on ligament fibers causing lig to stretch
    • 1o: mild
    • 2o: moderate
    • 3o: severe (rupture)
  14. JT capsule > function:
    Acts like ligament to maintain stability/support; houses synovial fluid
  15. JT capsule > Issues:
    • - Capsular tear: tensile stress injury; similar to lig sprain
    • - Capsular adhesion: fibrous adhesions of capsule to itself or adjacent TS
  16. Fascia > function:
    Provide support, shape & suspension for soft TS
  17. Fascia > Issues:
    • - Fascial tearing: scar TS form, lead to mvmt restriction
    • - Fascial shortenings: fascia adapts to shortened/elongated positions
  18. Nerve > function:
    Carries sensory & motor signals
  19. Nerve > Issues:
    • - Compression/Tension: eventually causes pathological reaction or complete rupture
    • - Degeneration: results from mech forces OR systemic disorders that attack nerve
  20. Cartilage > function:
    Protective cushion, provides rigidity/support
  21. Cartilage > Issues:
    - Degeneration: breakdown in integrity of cartilage matrix
  22. Bursa > function:
    Provide cushioning, reduce friction btw adjacent structures
  23. Bursa > Issues:
    - Bursitis: compressive damage (thickening of walls), results in inflammation
