Q

list 5 categories that lead to need for Stretching

A
  • Prolonged immobilization
  • Restricted mobility
  • Connective tissue or neuromuscular disease
  • Tissue pathology due to trauma
  • Postural malalignment with muscle imbalances
28
Q

define Stretching

A
  • Therapeutic maneuver designed to lengthen pathologically shortened soft tissue that have become hypomobile
  • To increase ROM and extensibility (to improve flexibility)
29
Q

discuss Passive Stretching

A
  • If the patient is as relaxed as possible, it’s called passive stretching
  • A form of static stretching in which an external force exerts upon the limb to move it into the new position
  • Passive stretching resistance is normally achieved through the force of gravity on the limb or on the body weighing down on it.
  • Is can also be achieved with the help of a partner, stretch bands, or mechanical device
30
Q

define Flexibility

A
  • The ability to move a single joint or a series of joints smoothly and easily through an unrestricted, pain-free ROM
  • depends on extensibilty of muscle and connective tissue
31
Q

define/discuss Extensibility

A
  • the ability to expand or stretch
  • muscle cells shorten when contracting, but can stretch beyond resting length with relaxed
  • flexibilty depends on extensibilty
  • property of muscles which cross joints to relax, lengthen, and yield to a stretch force
32
Q

discuss Active Inhibition

A
  • Reflexively relax the muscle for stretch (not the connective tissue)
  • Muscle must be normally innervated and under voluntary control
  • Not as effective if severe muscle weakness, spasticity, paralysis
  • The tight muscle is the antagonist, opposing muscle is the agonist
  • The enemy is the antagonist, the antagonist is the tight muscle
33
Q

define Overstretch

A
  • A stretch well beyond the normal length of muscle and ROM of a joint and the surrounding soft tissues
  • Results in hypermobility (excessive mobility)
34
Q

identify Positive Overstretch

A

Creating selective hypermobility for certain healthy individuals with normal strength and stability and who participate in sports that require extensive flexibility

35
Q

identify Negative Overstretch

A
  • Becomes detrimental when joint instability is created
  • When the supporting structures of a joint and the strength of the muscles around a joint are insufficient and cannot hold a joint in a stable, functional position during activities.
  • Instability of a joint often causes pain and may predispose a person to musculoskeletal injury
36
Q

define Contracture

A
  • an almost complete loss of function to decreased ROM
  • adaptive shortening of the muscle-tendon unit and the other soft tissue that cross or surround the the joint resulting in resistance to passive or active stretch or ROM
37
Q

identify 5 Types of Contractures

A
  • Myostatic
  • Pseudomyostatic
  • Adhesion
  • Arthrogenic/Periarticular
  • Irreversible/Fibrotic
38
Q

discuss Myostatic Contracture

A
  • (myogenic) musculotendinous unit has adaptively shortend and there is significant loss of ROM, but no pathology
  • Can be resolved with stretching exercises
39
Q

discuss Pseudomyostatic Contracture

A
  • Results from hypertonicity due to CNS lesion spasm, muscle guarding, pain
  • The result of hypertonicity (spasticity or rigidity) associated with CNS lesion, such as CVA or SCI or TBI.
  • Muscle spasm or guarding and pain
  • Muscles appear to be in constant state of contraction, but if neuromuscular inhibition procedures to reduce muscle tension temporarily are applied, full passive elongation is possible
40
Q

discuss Adhesion Contracture

A
  • Collagen fibers bond & adhere to each other in a disorganized manner
  • Scar tissue adhesion – collagen laid down randomly between normal tissue
41
Q

discuss Arthrogenic/Periarticular Contracture

A

• Tightening of connective tissue within the joint capsule
• Result of intra-articular pathology
• May include
o adhesions,
o synovial proliferation,
o joint effusion,
o irregularities in articular cartilage,
o osteophyte formation
• Develops when connective tissues that cross or attach to a joint or the joint capsule lose mobility
• Thus restricting normal arthrokinematic motion

42
Q

discuss Irreversible/Fibrotic Contracture

A
  • Soft tissue replaced by bone or fibrotic tissue
  • Fibrous changes in the connective tissue of muscle and periarticular structures can cause adherence of these tissues and subsequent development of a fibrotic contracture
  • Although it is possible to stretch a fibrotic contracture and eventually increase ROM, it is often difficult to re-establish optimal tissue length
  • Permanent loss of extensibility of soft tissues that cannot be reverse by nonsurgical intervention may occur when normal muscle tissue and organized connective tissue are replaced with a large amount of relatively nonextensible fibrotic adhesion and scar tissue, or even heterotopic bone
  • Changes can occur after lon periods of immobilization of tissues in shortened position or after tissue trauma and the subsequent inflammatory response
  • The longer a fibrotic contracture exists or the greater the replacement of normal muscle and connective tissue with nonextensible adhesions and scar tissue or bone, the more difficult it becomes to regain optimal mobility of soft tissues and the more likely it is that the contracture will become irreversible
43
Q

discuss Ballistic Stretching

A
  • A rapid, forceful intermittent stretch
  • A high-speed and high-intensity stretch
  • Characterized by the use of quick, bouncing movements that create momentum to carry the body segment through the ROM to stretch shortened structures
  • Not recommended for elderly or sedentary individuals or patients with musculoskeletal pathology or chronic contractures
  • Tissues, weakened by immobilization or disease, are easily injured
  • Dense connective tissue found in chronic contractures does not yield easily with high-intensity, short-duration stretch
  • May be appropriate for highly trained athlete who requires significant dynamic flexibility
44
Q

discuss the 6 General Principles of Manual Passive Stretching

A
  • Warm up muscles first
  • Patient must be relaxed
  • External force applied with attention/control of direction, speed, intensity, duration
  • Push beyond available ROM
  • Apply for 15-30 seconds, repeat several times
  • Slow maintained stretch is best to avoid stretch reflex and increased tension
45
Q

discuss the 2ish General Principles of Prolonged Mechanical Passive Stretching

A 
•	Low intensity (5-15 lbs or 10-15% of body weight) static stretch as long as possible
o	To increase comfort
o	Allows remodeling of collagen fibers
•	Applied via:
o	Serial casting
o	Dynamic splints
o	Pt positioning
o	Weighted traction
46
Q

discuss active inhibition Hold-Relax

A
  • Autogenic inhibition: tension in the tight muscle stimulates the golgi tendon organ which inhibits the motor neuron to this muscle and facilitates motor neuron to the opposing muscle
  • The tight (antagonist) muscle is contracted isometrically against resistance for 10 seconds (or more)
  • Then relax
  • Then IMMEDIATELY passively stretched
  • Repeat
47
Q

discuss active inhibition Contract-Relax

A
  • Autogenic inhibition: tension in the tight muscle stimulates the golgi tendon organ which inhibits the motor neuron to this muscle and facilitates motor neuron to the opposing muscle
  • Same as Hold-relax, but allows movement in rotation only if moving in a diagonal pattern
48
Q

discuss active inhibition Agonist-Contraction

A
  • Reciprocal inhibition: during facilitation of contracting the agonist muscle you get inhibition of the antagonist, which makes antagonist easier to stretch
  • Muscle opposite the tight muscle (the agonist) contracts concentrically against minimal resistance
49
Q

discuss active inhibition Hold-Relax-with-Agonist-Contraction

A
  • Autogenic inhibition, then Reciprocal inhibition
  • Isometric contraction of antagonist against resistance
  • Then relax
  • Then immediate voluntary concentric contraction of agonist against slight resistance
  • Then relax and increase ROM
50

59
Q

skin and scars

A

connective tissue:

  • skin is normally mobile, but maybe become tight if scar tissue develops, leads to limited motion
  • scars are denser connective tissue which does not yield to stretch due to crossbonding of collagen fibers
