Q

Concentric vs eccentric

A

concentric: requires more O2, more energy, more motor units. less mechanical efficiency. increase velocity , force decrease
eccentric: less O2, less energy required, less motor units, more mechanically efficient. increase velocity–> initial increase in force production, then levels off

33
Q

Why choose concentric or eccentric?

A

depends of functional activity pt. is trying to achieve

  • if patient very weak (<3/5) use eccentrics
  • eccentrics for activities that require high intensity deceleration or quick direction changes
  • late stage of rehab- eccentric @higher speeds and loads
34
Q

precaution for use of eccentrics

A

increased cardiovascular demand –> no Valsalva

  • increased incidence of DOMS
    • progress slowly and decrease freq as intensity increases
35
Q

isometric exercises

A

no visible joint motion
no appreciable change in muscle length- used for postural or joint stability
- used for protecting joint or tissue in acute stage of healing by activating muscles
-if functional activity uses isometric contractions

36
Q

types of isometric exercises

A

muscle setting: low intensity, little/no resistance, promotes relaxation and pain relief, retards atrophy

stabilization exercises: sub-maximal co-contractions, decr intability, usually done in mid range of joint, usually done in weight bearing

multiple angle: isomterics @ multiple joint postions, improve strength throughout ROM, used if dynamic full ROM resistance exercises are painful or contraindicated

37
Q

limitation of isometrics

A

strength improvements limited to the joiny angle in which exercise was done
little carry over to dynamic function
not very effective for endurance

38
Q

Resistance in pounds of theraband at 100% elongation

A 
Yellow 2.9
red 3.9
green 5
blue 7.1
black 9.7
silver 13.2
gold 21.6
39
Q

Why use isokinetics?

A

Pt. can generate max force output @ varying angles

during concentric isokinetics- increase velocity= decreased force, thus less joint compression forces

  • can accommodate painful arc
  • co-activation of muscle at higher velocities for improved stability
40
Q

energy systems when doing exercise

A

anaerobic exercise- high intensity and low reps

aerobic exercise- low intensity of larger muscle groups for extended periods

41
Q

full arc exercises-

A

resistance through full available range

- strengthens thru full AROM

42
Q

short arc exercises

A
  • limited range of motion resistance application
  • avoids arc of pain
  • unstable position of joint
  • protect healing tissue
43
Q

force velocity relationship

A

concentric- velocity of contraction increase, force generation decr

eccentric- velocity of muscle lengthening increase, muscle force generation increases initially then levels off

44
Q

Traction grade 1

A

(loosen)

  • small amplitude distraction,no stress on capsule
  • equalizes tension of muscle, cohesive forces and atmospheric pressure
  • used with all mobilizations and for pain relief
45
Q

traction grade 2

A

(tighten)

  • “taking up the slack”
  • enough distraction to tighten tissues around joint
  • maintain joint play when ROM is not allowed or for pain relief
46
Q

traction grade 3

A

(stretch)

  • stretch on joint capsule and on surrounding periarticular tissues
  • stretch structures to increase joint play
47
Q

Grading accessory mobility stiffness–> super mobile

A

0: complete bony ankyloses
1: significant joint stiffness
2: moderate hypomobility
3: normal
4: moderate hypermobility
5: significant joint laxity
6: completely unstable

48
Q

effects of joint mobilization

A

moves synovial fluid, enhances joint nutrition
maintains extensibility and tensile strength of the articular and periarticular tissues
provides sensory input

49
Q

3 typesof stress

A

tension
compression
strain

50
Q

Toe-region

A

considerable deformation
not much force required
most of function occurs here

51
Q

elastic range and limit

A

range: strain directly proportional to tissue ability to resist stress
- tissue at EROM with gentle over pressure
complete recovery takes place

limit: beyond this point, tissue does not return to original shape or length

52
Q

plastic range

A

extends to point of rupture
permanent change occurs
sequential failure of bonds between collagen fibrils and eventually collagen fibers
-necking-considerable weakening and failure is near

53
Q

effects of corticosteroids

A

results in decrease in tensile strength
fibrocyte death nextto injection site
- up to 15 weeks to recover

54
Q

effects of injury on type of collagen

A

lay down of type III collagen
weaker than type I mature collage
usually takes place around 3 weeks after injury

55
Q

3 types of neural inhibition stretch

A
  • hold relax or contract relax
  • agonist contraction
  • hold relax with agonist contraction
56
Q

contract-relax

A

take shortened muscle to its end range
perform a endd-range isometric contraction 7-10 sec
-voluntary relaxation to follow
-passively move limb into new range

57
Q

agonist contraction

A

patient concentrically contracts muscle opposite to range limiting muscle
-lowlevel resistance or AROM with no resistance
results in reciprocal inhibition

58
Q

contract relax with agonist contraction

A
  • pre-stretch isometric contraction

- followed by concentric contraction of muscle opposite to range limiting muscles

59
Q

4 phases of scar formation

A

inflammatory
granulation
fibroplasia
maturation

60
Q

inflammatory phase of scars

A

immediately after trauma

  • 24-72 hours
  • blood clotting begins almost instantly
  • followed by migration of microphages to start debriding area
61
Q

granulation phase of scar

A
  • uncharacteristic increase in relative vascularity of tissue
  • needed to meet metabolic needs of repairing tissue
  • the more vascular the tissue, the quicker the scar forms
  • – movement is helpful in this stage
62
Q

fibroplastic stage of scars

A

lasts 3-8 weeks

  • fibroplastic cells increase in number
  • increase in rate of production of collagen fibers and ground substance
  • binds to itself with weak hydrostatic bonds
  • therefore tissue elongation is easier
  • window of opportunity for shaping scar!
63
Q

maturation phase of scar

A
  • collagen matures, solidifies
  • maximal stress can be placed on tissue without fear if tissue failure
  • significant remodeling can still take place
64
Q

absolute contraindications of passive movement-manipulation

A

-joint hypermobility
- malignancy
-tuberculosis
-active osteomyelitis
severe osteoporosis
-unstable fracture
-acute ligamentous rupture

treatment D1

A

prone lying

initially same as D1
first 24 hrs prone lying. POE,EIL
if patient improves continue D1
day 3, if no improvement
- prone lying with hips laterally shifted away from painful side
-EIL with shifted position
76
Q

treatment of D2

A

use pillow technique to gradually reduce kyphosis until prone lying achieved
-start with 3-4 pillows under belly prone
-remove 1 pillow every 10-15 minutes
Time is key
-once the patient is able to lie prone, treat as D1
goal is to reduce lumbar kyphosis

77

examination to make sure shift is present
correction of primary lateral shift
teach self correction of lateral shift
recovery of extension as in D2
then progress to D1
78

look for a position of comfort
instruct patient to maintain this position for as long as possible
treatment should be tried along the line of D4 and D5
if symptoms increase, then modify

79

A

in flexion, if there is a marked deviation use flexion in step standing
