Joint Play Flashcards
What refers to bone movement; refers to movement of the body on anatomical planes (ex. flexion, extension, abduction)
Osteokinematics
What refers to movements that occur on the inside of the joint or between the articular surfaces?
Arthrokinematics
What are motions that occur between the articular surfaces; occurs so the joint can have normal orthokinematic movements to take place; they are not under voluntary control?
Component motions
What is a component motion where one articular surface rolls on another?
Roll
What is a component motion where one articular surface slides over another
Slide
What is a component motion where the bones move but the axis remains stationary?
Spin
Which position is where the articular surfaces of a synovial joint become fully approximated
Closed packed position
What is a position of a synovial joint where the surfaces are separated and the joint capsule is relaxed or untwisted?
Resting position
What is predictable pattern of restriction that occurs in the synovial joint when a pathological condition exists in the joint capsule?
Capsular pattern of restriction
Which grade of glide / traction manipulations is the initiation of movement of the joint surfaces either perpendicular to the joint surfaces or parallel (non corrective)?
Grade 1
Which grade of glide / traction manipulations is the movement of joint surfaces up to the first tissue stop, either perpendicular or parallel to joint surfaces (non corrective)?
Grade 2
Which grade of glide / traction manipulations is movement of joint surface up to and through the first issue stop (corrective)?
Grade 3
Which grade oscillation is small amplitude oscillatory movement performed between the issue of movement and tissue resistance (5 cycles per second)?
Grade 1
Which grade of oscillations is large amplitude oscillatory movement performed between the initiation of movement and tissue resistance (2-3 cycles per second)?
Grade 2
Which grade of oscillations is large amplitude oscillatory movement, performed within tissue resistance and backing out again (2-3 cycles per second)?
Grade 3
Which grade of oscillations is small amplitude oscillatory movement performed within tissue resistance (5 cycle per second)?
Grade 4
Which grade of oscillations is chropractic thrust (out of scope)?
Grade 5
What are the indications?
- Decrease range of motion
- Adhesions in joint capsule
What are the principles of joint play?
- Client must be relaxed to there is no muscle guarding; guarding = ineffective
- Therapist must be relaxed and comfortable so full attention is on the mobilization
- Mobilize the distal on the proximal surface of the joint
- Do not mobilize when joint surfaces are fully approximated
How to perform joint play?
- Position the joint for efficiency by moving the joint to the point of restriction and back off by approx. 10 degrees and then perform manipulation
- Mobilize one joint, in one direction at one time
- Do not mobilize if the patient is experiencing too much pain
- Assessment with joint play should be in, or close to, resting position, this helps to determine the amount of glide available in the joint
What are the effects of joint play?
- Increase range of motion
- Stretch tight joint capsules
- Reduce adhesions
- Pain and spasm reduction
- Encourage the successive action of the joint
What are the contraindications?
- Recent fracture
- Neoplasm
- Acute inflammatory disease
- Joint speiss
- Bacterial infection
- Acute pain response to the manipulation
- Caution with pregnancy
- Flare up arthritis
- Oseophytes
- Joint correction with plates, pins, screws
- Previously dislocated joint
- Hypermobile joint
