Joint Mobilization (Exam 1) Flashcards
Types of Arthrokinematic Motion
Roll, Glide(Slide), Spin
Is the rolling of one joint surface on another. New points on each surface come into contact throughout the motion.
Roll
A linear movement of a joint surface parallel to the plane of the adjoining joint surface. One point on a joint surface contacts new points on the adjacent joint surface.
Glide (Slide)
Rotation of a moveable joint surface on the fixed adjacent surface. The same point on each surface remains in contact with each other. Example: Shoulder Rotation
Spin
___ and ___ must occur simultaneously to preserve joint integrity in most cases.
Roll, Glide
If the moving joint surface ____ on its partner without simultaneously _____, the surfaces would separate in some places and impinge in others.
Rolls, Gliding
Passive joint movement for increasing ROM or decreasing pain. Force is light enough that patient can stop the movement.
Mobilization
Passive joint movement for increasing joint mobility or decreasing pain. Incorporate a sudden, forceful thrust that is beyond the patient’s control.
Manipulation
Self-stretching techniques that specifically use joint traction or glides that direct the stretch force to the joint capsule.
Self-mobilization
Concurrent application of a sustained accessory mobilization applied by a clinician and an active physiological movement to end range applied by the patient. Applied in a pain-free direction.
Mobilization with Movement
Capsule is most relaxed. Joint play is greatest. Joint surfaces have the least contact with each other compared to any other position.
Resting Position (Open-Packed/Loose-Packed)
Joint capsule and ligaments are taut. Maximum contact between concave and convex joint surfaces.
Close-Packed Position
Plane that passes through the joint and lies at a right angle to a line running from the axis of rotation (in the convex bony partner) to the middle of the contacting articular surfaces.
Treatment Plane
Moves with the concave joint partner.
Treatment Plane
Plane remains essentially stationary when the convex joint partner moves.
Treatment Plane
3 Basic Movements Joint Play
Traction, Compression, Gliding
Movement of bone directly away from opposing bony surface. Results in separation of joint surfaces.
Traction
Neutralizes pressure in joint without actual surface separation. Produce pain relief by reducing compression forces.
Grade I (Loosen)
Separates articulating surfaces, taking up slack or eliminating play within joint capsule. Used initially to determine joint sensitivity.
Grade II (Take up slack)
Involves stretching of soft tissue surrounding joint. Increasing mobility in hypo-mobile joint.
Grade III (Stretch)
Movement of 2 bones perpendicular to and towards the treatment plane. Joint surfaces approximate.
Compression
Bone movement parallel to the treatment plane. Results in a gliding movement between joint surfaces. Performed to test passive movement or to mobilize a joint.
