Q

Physiological effects of Joint Mobilization

A

-fires articular mechanoreceptors
-fires cutaneous and muscular receptors
-abates / stops nociceptors (pain receptors)
-decreases or relaxes muscle guarding
-causes synovial fluid movement & improves
nutrient exchange
-improves mobility and flexibility at the joint
-maintains tensile strength of articular tissues

Q

closed packed position

A

-joint position in which the articulating bones have their maximum area of contact with each other and it is called maximum congruency
-joint capsule becomes twisted causing the joint surfaces to become fully approximated and no further movement is possible
-joint stability = greatest
-Injury in the closed packed position will most likely result in fracture and/or dislocation

Q

open packed (loose) / resting position

A

-a position of the joint where the joint surfaces become separated and have little congruity and minimal joint surface contact
-joint capsule is relaxed and untwisted as well as the major ligaments
-joint is under the least amount of stress in this position, which is why we do most joint mobilizations in the resting position.
-joint stability = minimal
-sprains and strains occur - when swelling occurs the joint assumes the open packed position

Q

capsular pattern of restriction

A

-predictable pattern of movement restriction that occurs in a synovial joint when the entire joint capsule is injured / affected
-result of a total joint reaction
-pattern is named from the most restricted ROM to the least restricted
-When testing range of motions in a specific joint, one would find a predictable pattern of limitation to specific joint movements that can be measured and retested

Q

A

-when a concave surface moves on a convex surface, roll and slide must occur in the SAME direction

Q

joint play

A

-Arthrokinetic movements that occur between two articular surfaces within their ranges of motion
-Motion that is available between two articular surfaces in one direction - not under voluntary control

Q

principles of joint play (1-5)

A
  1. patient must be relaxed
  2. therapist must be relaxed & comfortable
  3. mobilize distal articular surface on proximal articular surface if possible
  4. do not mobilize when the joint surfaces are fully approximated or close packed
  5. position joint by moving joint to point of restriction & then back off by approximately 10º, then perform mobilization technique

Q

principles of joint play (6-10)

A
  1. mobilize one joint, in one direction and at one time
  2. do not mobilize joint if patient is experiencing pain during the mobilization. This may increase the inflammatory response, & muscle guarding
  3. assessment of joint with joint play should always be in the loose packed or resting position
  4. correct stabilization of other body parts are essential for the joint mobilization to be effective
  5. do not lever a joint - do not perform long lever roll manipulation. Joint play is a direction mobilization that is performed in direction of glide.
19
Q

principles of joint play (11-14)

A
  1. use pillows, rolled up towels, or high-density foam blocks to help stabilize the proximal joint surface
  2. watch for patient discomfort
  3. always re-assess after each treatment and prior to a treatment
  4. joint play should be used with other adjunct therapies, like soft tissue stretching, deep tissue massage and hydrotherapy
20
Q

causes of joint dysfunction

A

-Intra articular adhesions or pericapsular stiffness
-Shortened muscle groups around the joint
-Muscle weakness and imbalance around a joint
-Pain
-Nerve root adhesions
-Soft tissue restrictions

21
Q

indications for joint play

A

-most commonly associated with restoring ROM for the peripheral and axial skeleton joints
-primary indication = decreased ROM due to immobilization, usually from fractures, ligamentous sprains, tendonitis, or adhesive capsulitis
-any condition involving fibrosis or pseudo-fibrosis (relative capsular fibrosis) of the joint capsule is indicated for mobilization.

22
Q

joint play CI’s

A

hypermobility
joint effusion
inflammation

23
Q

methods of joint examination

A

Inspection
Palpation
Range of Motion (active vs passive)
Radiography (x-ray)
Computed tomography (CT scan)
Magnetic Resonance Imaging (MRI)
Conventional & Contrast Arthrography
Ultrasound Arthrography

24
Q

Inspection and Palpation - looking for…

A

-Swelling
-Skin changes
-Muscles, above and below the joint (wasting) compare to non injured side
-Deformity of any kind, bones misaligned, valgus or varus

25
Q

range of motion

A

-measurement of the amount of movement around a specific joint
-measures the amount of movement allowed by the shape of the joint & by the surrounding soft tissues
-may show the joint’s movement is limited, normal or excessive

26
Q

PROM

A

-therapist makes the motions of the joint while the patient is relaxed through the unrestricted range
-the patient does not contract muscles
-anatomic barrier = end of PROM

27
Q

AROM

A

-patient “actively” contracts the voluntary muscles crossing the joint, moving the joint through its ROM
-physiologic barrier = end of AROM

28
Q

grading joint play

A

-when applying joint mobilizations to specific joints, always start with the least stress on the joint and go to more and more stress
-use a grading system for both sustained glides or distractions & for oscillations
-each grade has a purpose & function within the grading system for a therapeutic effect on joints

29
Q

GRADE 1 - sustained

A

-initiation of movement of the opposing joint surfaces
-perpendicular to the joint surfaces for a distraction joint mobilization or parallel for a glide joint mobilization
=non-corrective

30
Q

GRADE 2 - sustained

A

-initiation of movement of the opposing joint surfaces
-perpendicular to the joint surfaces for a distraction joint mobilization or parallel for a glide joint mobilization
=non-corrective

31
Q

GRADE 3 - sustained

A

-movement of the opposing joint surface is up to and through the first tissue stop.
=corrective grade
-this grade of mobilization stretches joint capsule - perform this grade with caution

32
Q

grade 1 & 2 sustained - purpose

A

for pain management, introductory assessment and joint play (Grade 2) and assessment techniques

33
Q

grade 3 sustained - purpose

A

corrective technique to stretch the joint capsule & restore glide motions within the joint

34
Q

GRADE 1 - oscillations

A

-small amplitude
-between initiation of movement & tissue resistance
-5 cycles per second

35
Q

GRADE 2 - oscillations

A

-larger amplitude
-between initiation of movement & tissue resistance
-2-3 cycles per second

36
Q

GRADE 3 - oscillations

A

-large amplitude
-within tissue resistance & backing out again
-2-3 cycles per second

37
Q

GRADE 4 - oscillations

A

-small amplitude
-within tissue resistance to end of limited ROM
-5 cycles per second

38
Q

GRADE 5 - oscillations

A

-high velocity, small amplitude
-non-oscillatory movement, starts at tissue resistance & follows through in a thrust manipulation
-

39
Q

grade 1 & 2 oscillations - purpose

A

pain relief, warm ups or introductory techniques

40
Q

grade 3 & 4 oscillations - purpose

A

corrective oscillatory type mobilizations to mobilize and stretch joint capsules

41
Q

end feels

A

-when assessing passive movements, therapist applies overpressure at end of the range to determine the quality of the end feel -sensation the therapist “feels” in the joint as it reaches end of ROM of each passive movement

42
Q

normal end feels

A

-bony: hard, painless
-soft tissue approximation: mushy
-tissue stretch: firm, springy, elastic, slight give, may be hard / soft

43
Q

abnormal end feels

A

-early:caused by muscle/ligament tear, often acute
-late: caused by instability
-capsular: hard (chronic) & soft or boggy (acute), caused by capsule damage
-empty: caused by ligament rupture or tear, very painful
-bone to bone: caused by osteophyte, early restriction in ROM
-springy block: caused by internal derangement inside joint, common in meniscus, early restriction
