strain/sprains

Question 1

continued deform over time when constantly loaded

-in tissue, due to expulsion of water

Answer 1

creep

Question 2

corresponding eventual decrease in stress that occurs as fluid is no longer exuded

Answer 2

relaxation

Question 3

energy loss exhibited by a viscoelastic materials when they are subjected to loading and unloading cycles

Answer 3

hysteresis

Question 4

• the larger the stress load the greater the ___, which decreases when the load is applied a second time
• discs are less protected against rep loads

Answer 4

hysteresis

Question 5

• normal range of motion, where little force is req to remove the “crimping” or “slack” in the tissue
• after this, tissue resists elongation much more strongly

Answer 5

toe region

Question 6

small amount of damage to the tissue that occurs after taking out the slack in the soft tissue

Answer 6

micro failure

Question 7

the stress when plastic deformation starts

Answer 7

yield stress

Question 8

the tissue undergoes plastic deformation (grade 2 sprain), causes eventual tissue rupture (grade 3)

Answer 8

macro failure

Question 9

injury to soft tissue that occurs up to 72 hr

Answer 9

inflammation

Question 10

after 48h, injury will ___, and after 3 weeks to 12 months it will ___

Answer 10

repair

remodel

Question 11

a ___ is an overexertion or stress on contractil tissues

Answer 11

strain

Question 12

structure most at risk, esp LE like hamstrings, rectus femoris, medial gastroc, sometimes biceps brachii in UE

Answer 12

muscle

Question 13

structure that isnt truly contractile but is in series with muscle to transmit the force to the bone

Answer 13

tendon

Question 14

strain type with only a few of the fibers torn, there is only minor weakness and loss of function

Answer 14

grade one

Question 15

strain type with about 1/4-1/2 of the muscle/tendon torn, with moderate to major weakness and loss of function

Answer 15

grade two

Question 16

strain type with all fibers torn, major weakness and loss of function
-recovery post surgery is 3-6 mo

Answer 16

grade three

Question 17

overexertion or stress on NON contractile tissues like ligament and capsule

Answer 17

sprain

Question 18

sprain type with a few fibers torn, minor weakness, 2-4 wk recovery

Answer 18

grade one

Question 19

sprain type 1/4-1/2 of lig torn, moderate to major weakness/loss of fxn, recovery 6-12 wk

Answer 19

grade two

Question 20

sprain type with all lig fibers torn, major weakness and loss of fxn, unstable
-recovery post surgery 12 wk-6mo

Answer 20

grade three

Question 21

when the capsule has the most slack and joint is at its resting position

Answer 21

loose pack position

Question 22

joint surfaces are in the closest approximation and capsule and ligs are maximally stressed
-joint has no possible accessory movements

Answer 22

close pack position

Question 23

• joint restriction pattern in a joint due to limitations in CAPSULE
• any joint with a capsule has this pattern, has a specific pattern

Answer 23

capsular pattern

Question 24

joint that is excessively restricted due to adhesions in the capsule, eg frozen shoulder

Answer 24

adhesive capsulitis

Question 25

joint restriction with patterns that arise from abnormalities like joint mice, impingements, plica, other internal derangements

Answer 25

non-capsular pattern
