  1. Myostatic Contracture
    Muscle/tendon short, responds well to stretch
  2. Pseudomyostatic Contracture
    • Increase in tone due to CNS dysfunction (severe spasticity)
    • Looks like but is not muscular; result is muscle tightness
  3. Osteophyte
    Small, abnormal bony outgrowth.
  4. Fibrotic Contracture
    Replacement of CT resulting in irreversible contracture (may require surgery)
  5. Arthrogenic/Periarticular Contracture
    • Joint effusion
    • Synovial proliferation
    • Articular cartilage irregular
    • Osteophytes
    • Adhesions
  6. Passive Stretch
    Patient relaxed
  7. Patient assists in moving joint
    Assisted stretching
  8. Types of self stretching
    Flexibility exercise, active stretching, self-stretching
  9. Neuro muscular inhibition techniques: muscle spindle
    • Muscle sensory organ that senses muscle length
    • Stimulated by quick stretch, causing contraction of muscle and inhibition of antatgonist
  10. Neuro muscular inhibition techniques: GTO
    • Golgi tendon organ
    • By muscular junction
    • Senses tension in muscle from prolonged stretch or prolonged contraction
    • Protective mechanism to inhibit tension in muscle
    • Relaxes muscle
  11. 3 types of CT behavior during stress
    • Tension- Force pulling away
    • Compression- force pushing towards
    • Shear- Parallel force
  12. Toe Region CT
    Deformation of CT without much force. Stretches out wave of collagen fibers.
  13. Elastic Range
    • Go to EOR and a gentle stretch is applied
    • Bonds between fibers strained.
    • Micro failure between collagen bonds begins
    • Tissue returns to original size and shape when load released if not maintained
  14. Plastic Range
    • Range beyond elastic going to point of rupture
    • Tissue strained will have permanent deformation when stress released
    • Failure of bonds between collagen fibrils and eventually collagen fibers
    • Heat released
    • Collage fibers rupture resulting in increased ROM
  15. Tissue will return to shortened length after a stretch unless...
    The tissue is used
  16. To increase ROM...
    Collagen bonds must be broken, realignment of fibers must occur for permanent elongation
  17. Complete failure may occur from...
    Manipulation/trauma or repetitive submaximal stress
  18. Effects of immobilization on CT
    • Weakening of tissue and bonds
    • Adhesion formation¬†
    • Return to normal tensile strength slow
  19. Effects of Inactivity on CT
    • Decrease in size/amount collagen
    • Weakening of tissue
    • More elastic fibers
  20. Effects of corticsteriods on CT
    Decrease in tensile strength
  21. Determinants of stretching
    • Alignment and stability
    • Stabilization
    • Intensity of stretch
    • - Gentle, low intensity for increased comfort and to prevent muscle guarding
    • Long duration
    • - To increase ROM without excessive load/possible injury
  22. After application of stretch what position and modality?
    Cool in a lengthened position
  23. Immobilized tissue reaches...
    Failure more easily
  24. Remodeling and maturation beings.... (time)
    3 weeks and continues months to a year
