Q

True/False: If a rupture/tear is partial, pain is experienced. If it is complete, pain is not experienced.

A

True - if partial - pain is experienced in the region of breach when muscle is stretched or contracts against resistance, if complete - the muscle does not pull against the injury

23
Q

Where does soft tissue healing not occur?

Study These Flashcards
A

neurons, cells of the lens of the eye, cardiac muscle cells, differentiated muscle cells

24
Q

What is hemostasis?

Study These Flashcards
A

the arrest of bleeding through coagulation and vasoconstriction so that blood transforms from fluid state to solid

25
When does hemostasis occur and for how long?
occurs in inflammation phase, usually achieved within 6-8 hours but highly vascularized tissues/extensive damage may continue to bleed for days
26
What are the signs of inflammation?
redness, warmth, swelling, pain at rest, loss of function
27
What is the timeline of the inflammation phase?
peaks at 2-3 hours, usually lasts 4-6 days but can last a few weeks
28
Why are leukocytes essential to the inflammation process?
degrade and remove necrotic tissue and microbes via phagocytosis
29
What are the goals for controlling the effects of inflammation?
selective rest, ice, compression, elevation
30
What is the therapist's role during the acute/protection phase?
control the effects of inflammation (necessary during first 24-48 hours, RICE) facilitate wound healing, maintain normal function in unaffected tissues and body regions, patient education: expectations (duration of symptoms, etc), activity recommendations, precautions/contraindications, reassurance that these symptoms are usually short lived, movement intervention: controlled passive movement, tissue specific activities, general active movement of neighboring regions
31
What occurs during the proliferation phase?
signs of inflammation are decreased/eventually absent, removal of noxious stimuli, growth of capillary beds, collagen formation, wound contraction (inward movement of wound edges by myofibroblasts ~ day5), the immature CT is thin and unorganized so is extremely fragile and easily re-injured
32
What is the timeline of the proliferation phase?
can begin at 24-48 hours, peaks at 2-3 weeks, but may last up to 6 weeks
33
What are therapy goals for the subacute/controled motion phase?
initiation of active movement (isometrics, AROM, muscular endurance, resistance exercises, flexibility), progression of activities within tolerance of healing tissues, management of pain and inflammation, patient education (expectations of this stage, timeframe for healing, return to activities progressively, indicated against going above tissue tolerance
34
What are the signs of excessive stress?
exercise or activity soreness that does not decrease after a few hours and is not resolved after 24 hours, exercise or activity pain that comes on earlier or is increased over the previous sessions, progressively increased feelings of stiffness and decreased ROM over several sessions, swelling, redness, and warmth in the healing tissue, progressive weakness, decreased functional use of involved part
35
What occurs during the maturation phase?
scar retraction by myofibroblasts is usually complete by 21st day and scar stops increasing in size, so from day 21 to day 60, there is a predominance of fibroblasts that are easily remodeled, maturation and remodeling of scar tissue occurs as collagen fibers become thicker and reorient in response to stresses placed on CT.
36
Which of the following is true? a. if not properly stretched, fibers adhere and form a restricting scar b. after a few weeks, scar tissue is unresponsive to remodeling c. at this point, treatment is unavailable
A is true. b = at week 14, c = treatment requires either adaptive lengthening in the surrounding tissue or surgical release
37
What is the timeline of the maturation phase?
begins a few days after injury, can last up to a year
38
At one week, strength of connective tissue can be back to _% normal.
3
39
At 3 weeks, strength of connective tissue can be back to _% normal.
30%
40
At 3 months, strength of connective tissue can be back to _% normal.
80
41
True/false: Connective tissue strength may never recover the full 100% after injury.
true
42
What is the therapist's role in the maturation/return to function stage?
design a progressiion of exercises that safely stresses the maturing connective tissue in terms of both flexibility and strength, so the patient can return to functional and work-related activities, patient education about safe progression, expectations, guidelines for return to normal, movement intervention: flexibility, motor control, muscle performance, proprioception, endurance, activity specific drills, functional progression
43
What are the factors affecting healing?
patient, injury, tissue
44
What are the patient-related characteristics that can influence healing?
genetics, age, nutrition, general fitness, medical comorbidities, psychosocial status, lifestyle factors
45
What are the injury-related characteristics that can influence healing?
mechanism of injury, quantity of tissue involved, quality of injury site
46
What are the tissue characteristics that can influence healing?
healing potential due to blood supply, uniformity of injury, region
47
Rank the tissues in order of best outcome of healing.
muscle,tendon, extra-articular ligament, intra-articular ligament, articular cartilage, fibrocartilage
48
What happens to a tissue that is repetitively stressed beyond the ability to repair itself?
inflammatory response is perpetuated - proliferation of fibroblasts with increasing collagen production and degradation of mature collagen results in a predominance of new, immature collagen = overall weakening effect on tissue - progressive limitations
49
Cumulative trauma disorders results from what?
repeated submaximal loading or frictional wear with excess frequency and/or duration beyond adaptive capabilities which elicits a chronic inflammatory response
50
What may occur due to the stress imposed on tissues that are unable to respond due to repetitive or excessive nature of the stress?
prolonged or recurrent pain and functional limitations
51
What are the contributing factors associated with cumulative trauma disorders?
MSK impairments relative to muscle length, strength, power, and joint mobility; NMS impairments relative to motor control and proprioception; structural alignment; environmental features such as poor design of work stations, activity demands
52
The presence of what perpetuates the inflammatory response?
continued abusive load
53
What is the crucial element across all stages of rehabilitation for cumulative trauma?
management of contributing factors
54
What are the other rehab guidelines for acute cumulative trauma?
control inflammation, non-stressful activities
55
What are the other rehab guidelines for subacute cumulative trauma?
controlled stresses and continual monitoring
56
What are the other rehab guidelines for chronic cumulative trauma?
progression of stresses and development of endurance
