Test 4- Joint mobilization

Question 1

Joint mobilization

Answer 1

Selective stretching of specific tissue around joint without damaging adjacent tissue; stretching a capsular structure in physiological planes

• Remodels tissue, reduces stiffness and pain, encourages relaxation and bathes jt in synovial fluid
• All follow convex-concave rule

Question 2

Joint mob contraindications

Answer 2

• Jt replacements
• Fractures not healed
• Acute inflammation
• Bone disease
• Bacterial infection
• Malignancy (cancer)
• Unstable jt

Question 3

Osteokinematics

Answer 3

Movement produced by 2 adjacent bones; flexion, extension, adduction, etc.
-we can see and observe these motions

Question 4

Arthrokinematics (Accessory)

Answer 4

Essential movements that occur in joints as a result of osteokinematic motion but which CANNOT be produced by muscle action
-spinning, rolling, gliding, etc.

Question 5

Convex on concave movement

Answer 5

• concave= rounded inward, convex= rounded outward
• Glide on joint is to the OPPOSITE direction of movement of bone shaft
• example= glenohumeral joint

Question 6

Concave on convex movement

Answer 6

• Glide on joint is in SAME direction as movement of bone shaft
• example= the IP joints in digits

Question 7

Resting position (joints)

Answer 7

Position in which joint capsule and ligaments are most relaxed
-Evaluation/treatment position with hypermobile joints

Question 8

Loose-packed position (joints)

Answer 8

Articulating surfaces are maximally separated, giving the greatest amount of joint play
-Position used for traction and joint mobilization

Question 9

Close-packed position (joints)

Answer 9

Joint surfaces are in maximal contact to each other

-extremities of joint motion are in close-packed position

Question 10

Joint roll

Answer 10

A series of points on one articulating surface come into contact with a series of points on another surface

• Roll occurs IN DIRECTION of movement
• Example: femoral condyles rolling on tibial plateau
• Usually occurs on unequal surfaces

Question 11

Joint slide/glide

Answer 11

Specific point on one surface comes into contact with a series of point on another surface

• surfaces are congruent
• When passive mobilization technique is applied to produce a slide= GLIDE

Question 12

Joint compression

Answer 12

Decrease the space between two joint surfaces

-adds stability to a joint and releases lubrication for joint gliding

Question 13

Joint distraction

Answer 13

Two joint surfaces are pulled apart

-Often used with joint mobilization to increase stretch of capsule

Question 14

Oscillations

Answer 14

Pull out and push in joint in pulsating manor

-provides pain relief

Question 15

Traction grading: Grade I

Answer 15

Neutralizes pressure in joint without actual surface separation and produces pain relief by reducing compressive forces

• loosens joint, but not as much distraction involved
• Used for PAIN

Question 16

Traction grading: Grade II

Answer 16

Separates articulating surfaces, taking up slack or eliminating play with joint capsule

• Used to determine joint sensitivity
• Used to INCREASE motion

Question 17

Traction grading: Grade III

Answer 17

Involves stretching of soft tissue surrounding joint

• increases mobility in hypermobile joint
• Used to INCREASE motion

Question 18

Effects of joint mobilization

Answer 18

• Neurophysiological effects: stimulates mechanoreceptors to decrease pain, and affects spasm/muscle guarding
• Nutrition effects: causes synovial fluid release and can improve nutrition exchange
• Mechanical effects: improve mobility of hypermobile joints and maintains extensibility and tensile strength of articular tissue
