Joint Mobilization Principles/Techniques Flashcards
What is a Grade 1 movement?
Small amplitude performed @ beginning of range
What is a grade 2 movement?
Large amplitude mvmnt @ midrange
Grade 3 joint mob is a…
Large amplitude mvmnt UP TO limit of range
Grade 4 mvmvnt is…
Small amplitude mvmnt @ end range
Grade 5 mvmnt is…
Small amplitude, HIGH VELOCITY thrust performed to snap adhesions @ end range
Grades 1-2 are primarily used to….
Vs Grades 3-4 are primarily used to…
1-2 = stimulate mechanoreceptors in order to inhibit nociceptive stimuli (Gate control theory)
3-4 = increase ROM
When a concave surface moves on a FIXED convex surface, Roll and slide occur in the ____ direction; therefore mobilizing force should occur in the ___ direction as the bone movement
Concave moving on fixed convex = SAME direction roll/glide
Force applied in SAME direction as bone movement
When a convex surface moves on a fixed concave surface, roll and slide occur in the ____ direction;
Therefore mobilizing force should be applied….
OPPOSITE direction for both roll/slide and force applied!
LE Joints which move in opposite direction (convex on concave) (4)
- Hip (Femur in Acetabulum)
- Patellofemoral (Patella on Trochlear Groove of Femur)
- DISTAL Tibiofemoral (Convex Fib on concave Tib)
- Talocrural (ankle) (convex Talus moves on concave Fib/Tib)
*Subtalar = has movements both concave/convex; opposite direction occurs @ posterior aspect only
Indications (2) v Contraindications (8) for joint mobilization
Indications = Pain / restricted movement
Contraindications = Acute inflammation, active disease (RA, gout), osteoporosis, hypermobility, mm guarding, fracture, joint replacement
UE Arthrokinamatics - which joints are convex on concave/move in opposite directions?
(3)
Glenohumeral
Proximal RadioUlnar (see image)
Radiocarpal - in open chain movement, the convex surfaces of the scaphoid and lunate move on the concave surfaces of the radius
Apply joint mobs in opposite direction of movement!
55 deg abd + 30 deg horizontal add = resting position of which joint?
Glenohumeral
Resting position of radiohumeral joint?
Full ____ + full _____
+ osteokinematics?
Full extension + full supination
Concave radius on Convex humerus
70 deg flexion + 10 deg supination = resting position for which joint?
vs
70 deg flexion + 35 deg sup = ???
*osteokinematics of each?
Ulnohumeral (concave on convex/same diretion)
vs
Proximal RadioUlnar (convex on concave/opp direction)
Neutral position of distal radioulnar jt?
Artrokinematic motion?
10 deg supination
Same direction (concave radius moves over convex ulna)
