  1. spedific terminology should be used but, often is used interchangably:


    • Flexibility
    • ability of musculature/tendinous unit to elongate
    • terms used to describe: stiffness, pliable

    • ROM:
    • motion of a joint
  2. it is useful to identify what is inhibiting ROM.

    List (4) influences to ROM:
    • swelling
    • scarring: tissues (tendon, muscles, joint capsules, ligaments), soft tissues
    • structures
    • increased muscle tone/guarding: influence with contractions ( PNF)
  3. connective tissues are made up of collagen & other fibers within a ground substance.

    • provides strength or stiffness
    • bridges: how collagen is organized provides more or less strength
  4. connective tissues are made up of collagen & other fibers within a ground substance.

    • provides extensibility
    • stretch that returns to normal
  5. connective tissues are made up of collagen & other fibers within a ground substance.

    weaker temporary type III collage
  6. connective tissues are made up of collagen & other fibers within a ground substance.

    ground substance:
    • in between fibers
    • immobilization = less ground substance
  7. list the structures that are dense regular connective tissues: (2)

    how would you stretch dense regular conn. tissues:
    • tendon (dont want tendons flexible - contractions)
    • ligament

    • how to stretch:
    • straight: fibers run in one direction
  8. list the structures that are loose regular connective tissues: (1)
    connective tissue (organs)

  11. one must understand mechanical properties of connective tissues to stretch and fxn properly.

    list the (3) properties:
    • plastic
    • viscoelastic
    • elastic

    the extent of these vary by tissue
  12. the fluid like resistance to force that provides permanent deformation is called:

    there is no potential energy, so the tissues does not return, engergy is released as heat
  13. a property that allows stretched tissue to return to normal length post load is called:

    • long stretch may facilitate permenant deformation with proper stress
    • ability of soft tissues to return to its pre-stretch resting length directly after a short duration stretch force has been removed
  14. describe the mechanical property of visocelasticity:
    • a combintation of viscosity & elasticity
    • there is some return in length but not full

    soft tissue initially resists deformation, such as change in length, when stretch force is 1st applied, if stretch force is sustained allows a change in length & enables the tissue to return gradually to prestretch state after stretch force has been removed
  15. the property of connective tissue that allows for the ablity to undergo a permanent change in length after force is applied is called:

    change in length after force is greater than collage bridges

    soft tissue assumes a new & greater length after the stretch force has been removed
  16. list the (2) physical properties of connective tissue:
    • creep:
    • related to viscosity thus time dependent
    • when load is applied long enough you may get permanet elongation
    • time dependent = 15 mins +, weight or gravity
    • force/stress relaxation:
    • tension decreases, so may not need so much stress
    • decrease muscle tone
    • breaking cross bridges
    • long enough stress =  less force

    in order to elongate connective tissue must consider both
  17. the physcial property of connective tissue that describes elongation of tissues in the plastic range is called:

    list (2) ways this is typically acheived:

    • acheived with:
    • low load, long duration is most effective
    • heat: destabilizes cross bridge bonds w/ least damage
    • -less pain for pt.

    how warm: 3o TTR
  18. physial properties that lead to changes beyond plastic range & failure is called:
    fatigue failure-structural failure

    varies with duration, repetition or magnitude
  19. strain (deformation) of an object is directly related to ability to resist stress (load), as stated by:
    Hooke's law

    each body tissue has a unique stress strain curve

  22. once the elastic limit is reached, sequential failure of the collagen fibers & tissues occurs in the which range of the stress strain curve:

    what is the result & released:
    plastic range

    resulting in the release of heat & a new length when the stretch is released

    premanent deformation (5-10%) secondary to cross bridge breaking
  23. the region of the stress strain curve in which there is considerable weakening of the tissue & less force is needed for deformation is called:

    • total failure quickly follows even under smaller loads
    • ultimate strength
  24. the region of the stress strain curve in which each stretch increases heat allowing the next stretch to be more effective is called:

    repetitive stretching with sub max load effectivly increases length
  25. stretching techniques are based on stretch reflexes

  27. the neuromuscular afferants IA or primary afferant surround which part of the neuro fiber:

    what type of stretch does the IA (primary) respond to:

  29. the neuromuscular afferants Ib send messages from which type of receptor:

    which type of stretch does this respond to:
    • from which type of receptor: golgi tendon organ
    • responds to: tension
  30. when tension develops in muscle GTOs fires and inhibits alpha motor neuron that is under tension.

    why is this useful:
    PNF - the pt. has muscle tightness, GTO fires & inhibits the alpha motor neuron - then decreases muscle tone
  31. when a muscle is stretched (rapid or sustained) the muscle spindle responds by initiating _______ via the alpha motor neuron of the muscle stretched
    reflexive contraction
  32. when a stretch reflex is activated in the muscle being lengthened, decreased activity (inhibition) of the muscle on the opposite side of the joint is present which is known as:
    reciprocal inhibition
  33. if a stretch/tension held on a muscle is greater than 6 seconds an inhibitory impact on the muscle being held occurs which is known as:
    autogenic inhibition

    thus gains in flexibility may be from muscle fiber relaxation or noncontractile tissue lengthening
