Q

What are Articulations? (Synovial Joints)

A

Q

What is Arthrokinematic Motion (Roll) ?

A

• occurs between joint surfaces when new point on moving surface contacts new point on stationary surface
• in normal joint, occurs with slide or spin
• results in movement (swing) of bone
• always occurs in direction that bone is moving, regardless of whether moving surface is convex or concave

Q

What is Arthrokinematic Motion (Slide)?

A

• occurs when same point on moving surface contacts new points on stationary surface
• direction of slide depends on whether moving surface of joint is concave or convex
• slide occurs in sAme direction as roll if moving surface is concAve
• slide occurs in opposite direction of roll if moving
surface is convex
• relationship is known as CONCAVE-CONVEX RULE

Q

What is Arthrokinematic Motion (Compression)?

A

• occurs when there is decrease in space between two articulating joint surfaces
• compression normally occurs during weight bearing
• compression can occur when muscles contract – this can provide stability to the joint
• normal compression encourages movement of synovial fluid which helps maintain cartilage health
• abnormally high compression can lead to deterioration of articular cartilage

Q

What is Arthrokinematic Motion (Mobilizing)?

A

• applied to joint surfaces to decrease pain or restore normal arthrokinematics
• distractions can be applied on their own or in combination with glide
• when possible, grade I distraction should be applied with glide mobilization
• distractions & glides are applied using sustained or oscillatory techniques

Q

What is Arthrokinematic Motion (Glide)?

A

• glide is when you mobilize bone in direction that is parallel to treatment plane
• treatment plane is plane that lies parallel to concave surface of joint

Q

What are Grades of Mobilization Techniques?

A

Mobilizations are applied using either sustained or oscillating pressure & with different levels of force (i.e. grades).

17
Q

What is Sustained Mobilization?

A

Applied with consistent pressure in specific direction using specific level of force.

18
Q

There are three grades of sustained mobilization. What are they?

A

Grade I (loosen): minimal force, no stress on joint capsule
Grade II (tighten): sufficient force to tighten tissues around joint
Grade III (stretch): force large enough to place stretch on capsule & periarticular structures but not to anatomic limit

19
Q

What is Oscillatory Mobilization?

A

Applied with specific frequency of movement, in specific direction, using specific level of force

20
Q

There are four grades of oscillatory mobilization. What are they?

A

Grade I: small-amplitude, at beginning of range
Grade II: large-amplitude, not up to tissue resistance
Grade III: large-amplitude, into tissue limit
Grade IV: small-amplitude, into tissue limit

21
Q

What are Parameters of Mobilization?

A

Provide baseline structure for application. Parameters must be modified to ensure mobilization is safe & effective for given patient.

22
Q

What are Parameters of Mobilization (Sustained)?

A

• into specific direction (distraction or glide)
• hold for approximately 10 seconds
• rest for 3-5 seconds
• repeat for total of 1-3 minutes

23
Q

What are Parameters of Mobilization (Oscillatory)?

A

• into specific direction (distraction or glide)
• small-amplitude are applied like vibrations
• large-amplitude are applied 2-3/sec
• both small - & large-amplitude oscillations are applied for approximately 1 minute
• rest for 3-5 seconds
• repeat for total of 1-3 minutes

24
Q

What are Effects of Mobilization?

A

• neurophysiological: small-amplitude oscillatory & distraction movements may stimulate mechanoreceptors that inhibit transmission of pain signals
• mechanical: small-amplitude distraction & gliding movements facilitate synovial fluid motion which
encourages nutrition to avascular structures
• higher grade mobilization (sustained or oscillatory) will distend joint capsule & peri-articular joint
structures
• mobilization (especially with movement) can realign bony segments

25
What are Uses of Mobilization?
• grade I distraction: prior to glides (when possible) • grade II distraction: initial Ax to determine joint sensitivity & available movement • grade I and II oscillatory: decrease pain, increase nutrition • grade I and II sustained: decrease pain • grade II oscillatory and sustained: <-> ROM • grade III sustained/III & IV oscillatory: increase ROM, reduce positional faults/subluxations
26
What are Indications for Mobilization?
• pain, muscle guarding, & spasm can be treated with low grade oscillatory mobilizations • reversible joint hypomobility can be treated with ‘progressively vigorous’ mobilizations • positional faults/subluxations can be corrected with higher grade mobilizations (esp. with movement) • conditions that limit ROM: mobilizations can maintain ROM & possibly slow progression • immobilization: mobilization can help maintain ROM & offset degenerative/restrictive effects
27
Joint mobilizations cannot?
• alter disease processes (e.g., RA) • alter inflammatory process
28
Inappropriately applied joint mobilizations can?
• create/exacerbate hypermobility • traumatize joints/joint surfaces • initiate spasm/muscle guarding
29
What are Absolute Contraindications to Joint Mobilization?
• any undiagnosed lesion • joint ankylosis • high grade mobilizations only • hypermobility, ligamentous rupture, instability • joint effusion • inflammation • malignancy • osteoporosis • osteomyelitis • recent fracture • herniated discs with nerve compression
30
What are Relative Contraindications to Joint Mobilization?
• be careful & if in doubt, don’t mobilize • osteoarthritis • unhealed fracture (also note hand positioning) • hypermobility • total joint replacements • conditions that weaken CT (e.g., RA, advanced diabetes) • pregnancy (esp. lumbar spine & pelvis) • internal derangement
31
What is the CMTO’s Perspective of Joint Mobilization?
• don’t mobilize in close-pack position • communicate • assess (grade II distraction) before treating • distract before mobilizing when possible • joint tissues must be prepped prior to mobilizing (high grade only) • high velocity low amplitude (HVLA) thrust mobilizations are not applied to spine
32
What are the General Principles of Mobilization?
• prepare surrounding tissue prior to higher-grade mobilizations • make sure patient is comfortable, stable, & body segment being mobilized is supported • make sure your hand contact & any other means of stabilization is comfortable • when possible, your hands must be as close to joint as possible • assess joint movement with grade II distraction prior to mobilization • when possible, apply grade I distraction prior to any glide mobilization • your body & mobilizing segment should be moving as one (i.e., use your body effectively & efficiently) • mobilize one joint, in one direction, at one time • never mobilize through pain • never mobilize in close-pack position
33
How should we be Progressing a Mobilization?
• mobilizing in resting/loose-pack position is safest from which to start but not the most effective position in which to treat • to progress treatment, position joint at or near end of available & PAIN-FREE ROM prior to mobilizing – this will place restricting tissue in its most tensioned position where stretch force can be more specific & effective
34
What are patient responses to joint mobilization's?
• grade III & IV mobilizations can cause post-treatment soreness (but should not cause pain) • if patient experiences pain, soreness lasting more than 24 hours, worsening symptoms, swelling, or spasm, your treatment was likely too aggressive • between treatments, the patient should perform ROM into any newly gained range • mobilization (including self-mobilizations) should be applied every other day
35
What are Muscle Energy Techniques (MET)?
• these techniques use active contraction of muscles that attach near joint to correct joint misalignment • contractions are applied at the ‘barrier’ & progressed • usual precautions apply but also note any localized muscle pain/strains
36
What is the Application of Muscle Energy Techniques (MET)?
• contractions are isometric & gentle/submaximal • contract for 5-10 seconds • wait for the muscle to completely relax (usually about 3-5 seconds) • reposition to the next barrier/point of joint restriction • repeat 3-5x
