repetitive strain injury

Question 1

minor injury that never causes an acute response

stage of healing which includes the inflammatory response

Answer 4

acute stage

Question 5

stage of healing that includes proliferation, repair, and healing

Answer 5

subacute stage

Question 6

stage of healing in which inflammation decreases

Answer 6

subacute

Question 7

stage of healing in which pain is syncrhonous with encountering tissue resistance, with stressing new or short tissue beyond its tolerance

Answer 7

subacute

Question 8

how long does the subacute healing phase last

Answer 8

10-17 days

Question 9

how will tissue in the subacute phase test

Answer 9

weak, usualy short

Question 10

stage of healing that involves maturation and remodeling

Answer 10

chronic phase

Question 11

stage of healing with no inflammation

Answer 11

chronic

Question 12

stage of healing in which contractures/adhesions may limit range

Answer 12

chronic

Question 13

stage of healing in which muscle weakness/poor endurance/poor neuromuscular control may limit function

Answer 13

chronic

Question 14

stage of healing in which connective tissue remodels and strengthens in response to stress

Answer 14

chronic

Question 15

stage of healing in which stretch pain may be felt due to tight/adhered structures

Answer 15

chronic

Question 16

how long does the chronic stage of healing last

Answer 16

6-12 months

Question 17

how does chronic inflammation differ from acute

Answer 17

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

Question 18

what results from chronic inflammation

Answer 18

increased collagen production

Question 19

how does increased collagen production during chronic inflammation affect tissue

Answer 19

a predominance of new, immature collagen results to weakened tissue

Question 20

how do many repetitive strain injuries present themselves

Answer 20

slow, insidious onset

Question 21

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

Answer 21

slow onset leads to adaptation and delayed seeking of treatment

Question 22

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

Answer 22

often severe and progressive

Question 23

3 causes of chronic inflammation that results in structural weakening

Answer 23

overuse, cumulative trauma, repetitive strain

Question 24

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

Answer 24

trauma followed by superimposed repetitive trauma

Question 25

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

Answer 25

scar tissue

Question 26

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

Answer 26

contractures/poor mobility

Question 27

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

Answer 27

tendons

Question 28

why do tendons take longer to heal than a muscle

Answer 28

less vascularized

Question 29

what does chronic inflammation lead to

Answer 29

tissue destruction

Question 30

what do fibrosis and scarring lead to

Answer 30

tendon weakening/dysfunction

Question 31

term referring to tendon pathology

Answer 31

tendonopathy

the degenerative phase of a tendon

Answer 33

tendonosis

Question 34

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

Answer 34

tendonosis

Question 35

inflammation of a tendon sheath

Answer 35

tenosynovitis

Question 36

the repair and replacement of inflamed tissues by connective tissue

Answer 36

fibrosis

Question 37

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

Answer 37

adhesion

Question 38

impairments associated with acute injury

Answer 38

inflammation/SHARP

Question 39

impairments associated with subacute/chronic injury

Answer 39

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

Question 40

postural findings for chronic strain injury

Answer 40

postural faults, potential dysfunction

Question 41

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

Answer 41

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

Question 42

how do repetitive strain injuries present in ROM tests

Answer 42

pain with resisted testing, possible pain with stretch

Question 43

what is the treatment plan for acute injury regarding inflammation

Answer 43

control inflammation with cold hydrotherapy, elevation, lymph drainage

Question 44

calcium deposits in a damaged tendon

Answer 44

calcific tendonitis

Question 45

a cystic tumor developing in a tendon sheath

Answer 45

ganglion

Question 46

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

Answer 46

stenosing tenosynovitis

Question 47

aka for stenosing tenosynovitis
