Q

connective tissue properties (3):

A
  • warmer temp = greater flexibility
  • connective tissue is a passive restraint to joint motion
  • muscle tissue is an active restraint to joint

Q

What determines flexibility (6):

A
  • muscle length
  • joint ROM
  • joint mobility
  • extensibility of surrounding soft tissues
  • joint arthrokinematics and osteokinematics
  • strength

16
Q

How to increase flexibility and ROM (3)

A
  • stretch what’s tight (mm, restricted ROM, jt capsule)
  • joint mobilization (if indicated)
  • strengthen what’s weak.
17
Q

4 types of stretching:

A
  • static (passive)
  • dynamic (active)
  • ballistic (BAD)
  • proprioceptive neuromuscular fascilitation (PNF)
18
Q

stretch: placing a muscle in a fully elongated position and holding that position for a period of time

goals:

  • prevent or minimize risk of soft-tissue injury during activity
  • improve flexibility
  • prevent contracture
A

static stretching

19
Q 
stretch:
performed actively by moving joints
- body weighted or eliminated position
- through avaiable range
- gradually increase range and speed
- does not diminish torque production
- good to warm-up for sport/activity
A

dynamic stretching

20
Q

stretch:
bounce at the end of ROM

  • high risk injury to the connective and contractile tissue with this type of stretching
  • likely will NEVER use in rehab
A

ballistic stretching

21
Q

stretch:

reflex inhibition and subsequent elongation of the contractile elements of the muscle

involves the Golgi Tendon Organs in the myotendinous junction, and the muscle spindles

A

proprioceptive neuromuscular facilitation (PNF)

22
Q

a reflex relaxation that occurs in the same muscle where the golgi tendon organ is stimulated

(via isometric or isotonic contraction)

A

autogenic inhibition

23
Q

contracting the opposing muscle group to that being stretched in order to achieve a reflex muscular relaxation that occurs in the muscle that is opposite the muscle where the golgi tendon organ is stimulated

A

reciprocal inhibition

24
Q

types of PNF (3):

A
  • hold relax
  • contract relax
  • slow reversal hold
25
Q

PNF:

  • gentle isometric contraction of muscle being stretched
  • 6-10 seconds followed by stretch into new range
A

hold relax

26
Q

PNF:

  • gentle isotonic contraction of muscle being stretched
  • 6-10 second followed by stretch into new range
A

contract relax

27
Q

parameters for stretching/flexibility/ROM

A
  • ALWAYS warm up 5-10 minutes
  • determine mode
  • intensity: mild to moderate stretch, no pain
  • duration: 30-60 seconds, 3-5x per series
  • frequency: daily
    ( must stretch at least 3x/wk to gain and 1x/per wk to maintain
28
Q

due to scar tissue formation between tissue structures and results from the healing or union of two injured or torn parts

collagen fibers are highly unorganized initially but organize based on stresses placed on it

A

adhesions

29
Q

adaptive shortening of the muscle-tendon unit and other soft-tissues that crcoss or surround a joint qhich results in significant resistance to passive or active stretch and limitation of ROM

can be transient or permanent

A

contractures

30
Q

longer a contracture exists OR the greater % of normal tissue replaced by scar tissue or bone, the more difficult it becomes to regain optimal mobility of soft tissue =

A

more likely contracture will become irreversible

31
Q

stretch parameters for contractures:

A
  • requires low load, long duration (LLLD) stretching
  • aggressive
  • prolonged stretch into restriction 20-60 mins
  • may be done in conjunction with heating
  • bracing, serial casting
32
Q

precautions to stretching (5):

A
  • avoid ballistic stretching to allow relaxation and prevent injury
  • avoid overstretching
  • use caution with known diseases
  • stretch carefully if swelling/edema present or in patient has been immoblized for prolonged length of time
  • residual soreness should not last > 24 hrs
33
Q

contraindications to stretching (5)

A
  • if motion is limited by a bony block
  • across an acute of non-unioned fracture
  • acutely inflamed and infected tissue
  • hypermobile tissues or joints
  • hypomobile tissues that provide structural or neuromuscular support
