25
Q

Why are acute tendon tears more likely with age and disuse?

A
  • Elastin and vascularity decrease
  • Atrophy and drying
  • Shorter smaller tendon is less pliable and durable
26
Q

When do most tendinitis heal?

A
  • Primarily resolution of inflammation
  • At most in 4-6 weeks (sometimes 2 weeks: inflammation phase)
27
Q

When do most tendinosis and smaller tears heal?

A
  • Primarily proliferating tendon (repair phase)
  • Tensile strength initially improves at 3-5 weeks
  • Even greater tensile strength when dense fibrous tissue fills in at 8 to 12 weeks
  • Gradual and partial tears can improve with PT
28
Q

Traumatic and full tear tendinosis likely require what?

A
  • Surgery
  • 10-12 months to normal strength postoperatively
29
Q

What kind of patient education should you be doing with patients with tendinitis and tendinosis?

A
  • Load management: optimal loading
  • POLICED
30
Q

NSAIDS should be used for _____ _____ pain relief in acute presentations.

A

Short term … because they dont address the problem

31
Q

NSAIDS delay healing if the injury is where?

A

At the insertion

32
Q

NSAIDS have poor response and no support in what kind of tendinitis and tendinosis presentations?

A

Persistent presentations … because they have little to no inflammation at this point

33
Q

Bracing (neoprene sleeves on the involved muscles) and taping (prn/ straps) decrease what?

A

The resistance arm

34
Q

Do modalities have any impact on tendinitis and tendinosis?

A

Modalities - iontophoresis, ultrasound, phonophoresis, and low-level laser treatment lack sufficient evidence at this time

35
Q

What should you tell you patient with a tendinosis in regards to their soreness with ADLs and exercise?

A

It is okay to have mild symptoms during or up to 24 hours after exercise, but no more and no longer

36
Q

What does manual therapy help with in regards to tendinosis?

A

Manual therapy helps to restore accessory motion as needed

37
Q

What should be the primary and ultimate goal for tendinosis MET?

A
  • Tendon proliferation
  • Possible spinal stabilization if regional interdependence
38
Q

When should you implement parameters for tendinosis?

A

After any acuity settles and for all structural changes in tendon, including tears

39
Q

Should your parameters have heavy or light loads with tendinosis?

A

Heavy

40
Q

What kind of actions should you do with tendinosis parameters?

A
  • Slow eccentrics
  • Possibly 3 second muscle actions (concentric, isometric, and eccentric)
41
Q

Parameters pertaining to actions and ranges for tendinosis are what… (he uses an example with the biceps … shortened position is elbow flexed and shoulder flexed)

A
  • Isometric loading without compression from lengthening - isometrics in a shortened position
  • Isotonic loading without compression from lengthening - isotonic from neutral into shortened position
  • Isotonic loading with compression from lengthening - isotonic from a lengthened position
  • (Isometric loading in weight bearing), I.e., UE weight shifting, planks, push ups, etc
  • Plyometric loading, I.e. ball bounces, tosses, throwing, etc.
42
Q

What kind of position prevents compression?

A

Shortened

43
Q

How many sets, reps, and exercises should you give your patient with a tendinosis?

A
  • 2-3 sets of 10-15 reps to fatigue
  • 2-3 exercises with involved tendons
44
Q

What kind of activity response should you see with a tendinosis?

A
  • Mild to moderate increase in pain possibly up to a 5/10
  • Timeframe of pain should ease back to baseline levels before repeating exercises 24-48 hours
  • Soreness Rule: Mild symptoms during or up to 24 hours after exercise as long as it is no more or no longer
  • Most likely can repeat exercises every other day; may increase to daily in higher level patients
45
Q

How long should your MET program be for a tendinosis?

A

8-12 weeks

46
Q

What kind of tendinosis populations should have precautions with heavy loads to fatiguing points?

A
  • Deconditioned populations
  • Peri-pubescent population until growth plates are fused
47
Q

What are the most important areas to watch for growth plate fusions?

A
  • Humeral head epiphysis at the shoulder
  • Last growth plates to fuse are the ASIS, ischial tube, and the base of the 5th metatarsal
48
Q

What muscle attaches to the ASIS?

A

Sartorious

49
Q

What muscles attaches to the Ischial tuberosity?

A
  • Big picture: Hamstrings!
  • Inferior Gemellus
  • Quadratus Femoris

A

Fibularis Brevis

51
Q

What is a predisposition patients with tendinosis have? (in regards to healing)

A

Patients have a predisposition or prevalence for “failed healing response”

52
Q

Pts with both a tendinosis and obesity are prone to what complication?

A

Obesity: excessive fat absorbs inflammatory cells away from the tendon

53
Q

Pts with both a tendinosis and diabetes are prone to what complication?

A

Diabetes: excessive glucose impairs collagen production and remodeling

54
Q

Low grade and persistent inflammation is associated with what (in regards to tendinosis).

A
  • Associated with systemic disease(s) and/ or SAD diet
  • Limits proliferation and remodeling
55

A

No

56
Q

Short term benefits

57
Q

What kind of benefit do glycerin trinitrate patches have?

A
  • Last option
  • Expensive
