Q

how does chronic inflammation differ from acute

A

due to repetitive stress lasts beyond acute period. and on a cellular level: an upregulation of fibroblasts, increased microphages, and increased lymphocytes

21
Q

what is the main problem with the presentation of repetitive strain injuries

A

slow onset leads to adaptation and delayed seeking of treatment

22
Q

compared to acute inflammation, how does chronic inflammation present with tissue fibrosis

A

often severe and progressive

23
Q

3 causes of chronic inflammation that results in structural weakening

A

overuse, cumulative trauma, repetitive strain

24
Q

cause of chronic inflammation, ex: premature return to function following an acute strain

A

trauma followed by superimposed repetitive trauma

25
Q

cause of chronic inflammation. an injury site is predisposed to future injury due to altered force transmission and energy absorption

A

scar tissue

26
Q

cause of chronic inflammation. dysfunctional posture or prolonged stillness may lead to these issues that can become stressed with repeated or vigorous activity

A

contractures/poor mobility

27
Q

when muscles are unable to bear a given load where does the load pass on to

A

tendons

28
Q

why do tendons take longer to heal than a muscle

A

less vascularized

29
Q

what does chronic inflammation lead to

A

tissue destruction

30
Q

what do fibrosis and scarring lead to

A

tendon weakening/dysfunction

31
Q

term referring to tendon pathology

A

tendonopathy

32
Q

acute or chronic inflammation of a tendon

A

tendonitis

33
Q

the degenerative phase of a tendon

A

tendonosis

34
Q

tendonopathy characterized by disrupted collaged fibres within the tendon, increased cellularity, neurovasculaization

A

tendonosis

35
Q

inflammation of a tendon sheath

A

tenosynovitis

36
Q

the repair and replacement of inflamed tissues by connective tissue

A

fibrosis

37
Q

the sticking of collagen fibres that make up scar tissue to surrounding tissue

A

adhesion

38
Q

impairments associated with acute injury

A

inflammation/SHARP

39
Q

impairments associated with subacute/chronic injury

A

adhesions, scarring, myofascial restrictions, decreased mobility/increased connective tissue density, trigger points

40
Q

postural findings for chronic strain injury

A

postural faults, potential dysfunction

41
Q

repetitive strain injury will test how on palpation (5 answers)

A

tender, heat/swelling if inflamed, edema if subacute, granular texture at the lesion site, adhesions

42
Q

how do repetitive strain injuries present in ROM tests

A

pain with resisted testing, possible pain with stretch

43
Q

what is the treatment plan for acute injury regarding inflammation

A

control inflammation with cold hydrotherapy, elevation, lymph drainage

44
Q

calcium deposits in a damaged tendon

A

calcific tendonitis

45
Q

a cystic tumor developing in a tendon sheath

A

ganglion

46
Q

inability of a finger to flex or extend as a result of a nodule or thickening of a tendon

A

stenosing tenosynovitis

47
Q

aka for stenosing tenosynovitis

A

trigger finger

48
Q

can treating a muscle assist in the acute stage of tendonopathy

A

yes

49
Q

how to tell the difference between bursitis and tendonosis

A

bursitis: pain when releasing a contraction

50
Q

bursitis called Swimmer’s Knee

A

pes anserine

51
Q

bursitis called Baker’s Cyst

A

popliteal
