Joint Mobilizations Flashcards
What are Joint Mobilization Techniques?
Are used to modulate pain and treat joint impairments that limit ROM by specifically addressing the altered mechanics of the joint.
What are physiological movements?
Are movements the client can do voluntarily.
The term osteokinematics is used when these motions of the bones are described.
What are accessory movements?
Are movements in the joint and surrounding tissues that are necessary for normal ROM but that cannot be actively performed by the client.
The term arthrokinematics are used to describe these movements (distraction, slide, rolling, and spinning)
What are the Types of Motion?
Swing: Movement of the bony lever about an axis of motion
Motion of the bone surfaces in the joint
- Roll
- Slide/translation
- Spin
What is thrust?
Is a high-velocity, short-amplitude they are performed at the end of the pathological limit* of the joint and is intended to alter positional relationship, snap adhesions, or is applied to a dislocated structure to reposition.
*Pathological limit means the end of the available ROM when there is restriction.
What is muscle energy?
The use of active contraction of deep muscles that cause the desired accessory movement.
What is self-mobilization (auto mobilization)?
This refers to self-stretching techniques that specifically use joint traction or glides that direct the stretch force to the joint capsule.
What is mobilization with movement?
It is the concurrent application of sustained accessory mobilization applied by a therapist and an active physiological movement to end-range applied by the patient.
What is compression?
Normally occurs in the extremity and spinal joints when weight bearing
Normal intermittent compressive loads help move synovial fluid therefore maintaining cartilage health.
What is traction/distraction?
Traction is a longitudinal pull.
Distraction is a separation or pulling apart.
What is the Concave-Conves Rule?
Sliding is in the opposite direction of the angular movement of the bone if the moving surface is convex.
(Slide is opposite to the swing.)
Sliding is in the same direction if the moving surface is concave
(Slide is the same as the swing.)
Passive Angular Stretching VS. Joint-Glide Stretching
Passive stretch used on a tight joint capsule may increase pain or joint trauma because the lever increases the force at the joint; it causes excessive joint compression in the direction of the roll.
Joint glide replicates the sliding component of the joint and doesn’t compress the cartilage
- Controlled
- Replicates normal joint mechanics
- Force is specific to target tissues
What are the benefits of joint motion?
- Helps move synovial fluid to maintain cartilage health
- Maintains extensibility and tensile strength of articular and periarticular tissues
- Provides sensory input for proprioceptive feedback important for balance response
What are the indications for joint motion/manipulation?
- Pain, Muscle Guarding, and Spasm
- Neurophysiological effects
- Mechanical effects
- Reversible Hypomobility
- Positional Faults/Subluxations
- Progressive Limitation
- Functional Immobility
What are the limitations of joint motion/manipulation?
- Cannot change disease process
- Cannot change inflammatory process
- Skill of the therapist affects the outcome
