Definitions

Question 1

Isotonic contraction

Answer 1

Muscle origin and insertion get closer together without a change in tension

Question 2

Concentric contraction

Answer 2

Origin and insertion get closer together (i.e. the first part of a bicep curl)

Question 3

Eccentric contraction

Answer 3

Origin and insertion get farther apart (i.e. the second part of a bicep curl)

Question 4

Isolytic contraction

Answer 4

Type of eccentric contraction–> muscle contraction against resistance where muscle is forced to lengthen (i.e. operators force is more then patients force)

Question 5

Isometric contraction

Answer 5

Increase in tension without origin/insertion movement/approximation (i.e. muscle energy)

Question 6

Q Angle, normal range?

Answer 6

ASIS to central patella

17 degrees in females, 14 degrees in males

Question 7

Levoscoliosis

Answer 7

Convex left scoliosis (SB R)

Question 8

Dextroscoliosis

Answer 8

Convex R scoliosis (SB L)

Question 9

Physiologic barrier

Answer 9

Point where patient can actively move joint

Question 10

Anatomic barrier

Answer 10

Point where physician can passively move joint

Question 11

Restrictive barrier

Answer 11

Before the physiologic barrier, prevents full ROM

Question 12

Arm carrying angle

Answer 12

Normal 5-15 degrees
Increased= cubitus valgus (ulnar abduction dysfunction)
Decreased= cubitus varus (adduction dysfunction)
