Surfaces Shape and Jt Movements

Question 1

Concave Surface

Answer 1

slide will occur in the same direction as the bone is moving

when mobilizing a concave jt, you glide in the same direction as the mov’t you want to gain

Question 2

Male surface

Answer 2

convex

Question 3

Female surface

Answer 3

concave

Question 4

Convex surface

Answer 4

slide will occur in the opposite direction as the bone is moving
when mobilizing a convex jt, you glide in the opposite direction as the mov’t you want to gain

Question 5

Capsular Pattern

Answer 5

characteristic pattern of joint restriction in response to jt arthritis/inflammation

Question 6

Closed Packed Position

Answer 6

Jt position where the articular surfaces are maximally congruent, capsule and most ligaments are taut
Jt surfaces are difficult to separate
Most stable jt position, biomechanicaly efficient
Cannot get to the closed packed position muscle overuse issues are common with compensatory adaptations proximally or distally
Avoided for splinting

Question 7

Implications for mobilisation

Answer 7

Twofold
Position can be useful for locking the jt so mobilization of a nearby jt can be done with more specificity
Jt cannot be mob in the closed packed position

Question 8

Loosed Packed Position

Answer 8

any position that is not closed packed

Question 9

Resting Position

Answer 9

Position of the jt that has the greatest jt space and the least resistance to distraction
Position used for splinting or casting, use to mobilise acute jts
20-40 degrees tibfib flexion
