Q

Examination findings associated with Joint mobiltiy deficits

A
  • Subjective: reports tightness/stiffness and/or referred pain in familiar pattern associated with joint. Pain with initial movement but gets better with more movement. (Ex: After sitting for a while tightens up; tight in morning gets a little better but still limited)
  • AROM: loss of motion. Feeling of tightness in joint OR pinching in joint toward the direction of motion (Bend knee, have pain in posterior portion of the knee)
  • PROM: AROM loss of motion = PROM loss of motion
  • End range overpressure: CAPSULAR end feel with or without pain (Ex: Expected soft tissue approx with bend knee and feel capsular; Shoulder ex rot capsular end feel comes earlier)
  • Palpation: MAY have tenderness to joint with or without referral that REPRODUCES patient’s pain
  • Motor: MAY have weakness of muscles that cross the joint

Deficits or loss of coordination of muscles that cross a joint

Q

Non-Thrust Mobilization definition

A

Passive joint movement (accessory or physiologic motion) applied at varying points in the ROM and at different amplitudes.

Pressure to humeral head and move it or grab the humerus and move it (Arthrokinematic/accessory motion vs osteokinematic/physiologic motion)

Q

“Mechanisms” of Joint Mobilization

A

Biomechanical: restore normal arthrokinematics by improving joint capsule extensibility (restore necessary slide and glide to the joint)
Neurophysiological: Modulate and/or decrease pain output by stimulating peripheral and central nervous system (Anytime we put our hands on the patient)
Biopsychosocial: perception that the technique is helpful based onpatient’s own personal belief(Anytime we put our hands on patient; positive or negative)

Q

Biomechanical Mechanism

A
  • Based on the concept of restoring the osteokinematic and arthrokinematic motion of the joint and/or improving joint capsule extensibility
  • Osteokinematic motion: Physiological motion (flexion, extension, abd, etc); Can control motion
  • Arthrokinematic motion: Accessory motion (roll, slide, spin); Cannot control

Need both arthro and osteo to have full ROM

Q

Arthrokinematic Concepts CONVEX ON CONCAVE Motion

Direction of the force we apply during the mobilization is based on biomechanical principles

A

Convex articular surface moving on a fixed concave surface
The gliding motion of the convex joint surface moves in the OPPOSITE direction to the motion of the bone that is moving
Otherwise stated: The osteokinematic motion and the arthrokinematic motion occur in the OPPOSITE direction

To facilitate shoulder abduction, need an inferior glide of the humeral head.

A
  • Concave articular surface moving on a fixed convex surface
  • The gliding motion of the concave joint surface moves in the SAME direction to the motion of the bone that is moving

Q

Knee Extension

A

Tibia is stationary, Femur is moving: Arthro goes in a posterior direction, Osteo goes in an anterior direction; PT should push in a posterior direction.

Tibia is moving, Femur is fixed: arthro and osteo is same direction; provide an anterior force

Distal is moving - Open: Prixmal part of joint is moving - closed

Q

Direction of force for Mobilization Techniques MAY be dependent on arthrokinematic principles

A

Where restriction is and what part of joint is moving.

PT Mobilization force is applied in the OPPOSITE direction of the ostekinematic motion

PT Mobilization force is applied in the SAME direction of the ostekinematic motion

17
Q

Use joint play assessment to determine vigor of technique

Normal vs. Hypermobility vs. Hypomobility

A

All of these depend on the irritability of the patients symptoms
Where they feel the pain when we move the joint
R1: First resistance
R2: End resistance

More vigorious at R2

18
Q

Neurophysiological Mechanism

A
  • Peripheral neurological response
    – Stimulate joint mechanoreceptors
    — gait theory of pain
    — Reduces inflammatory mediators (i.e.: cytokines)
  • Central neurological response
    – Decrease activity of pain processing centers in the brain (anterior cingular cortex, amygdala, periaqueductal gray (PAG), rostral ventromedial medulla (RVM))
    – Enhance and sharpen somatosensory cortex and body maps through movement(enhance motor control/quality of movement of the joint)
    – Newer research through functional MRI’s

Change cortical pathway and pain pathway

Changes in the brain with peripheral or spinal joint

19
Q

Neurophysiologic response that results in…

A

Decrease pain, decrease tone of muscles and increased motion

20
Q

Dorsal area of the ____ and ____ have been shown to selective produce ____ and cause ____ and ____

A

Dorsal area of the PAG and RVM have been shown to selective produce analgesia and cause sympatho-excitation and the release of endorphins and enkephalins (Decrease the output of pain)

21
Q

Movement associated with joint mobilization helps to sharpen the body image of the somatosensory cortex which becomes distorted/ blurred (“smudged”)with pain and/or immobility

A
22
Q

Psychosocial Mechanism

A
  • Patient expectation (i.e.: patient BUY IN!) influences effectiveness of treatment (placebo response?)
  • Patient senses motion but without the THREAT or anticipation of pain
  • Low fear of the mobilization technique: Good outcomes
  • High fear on the mobilization technique: Less favorable outcome
  • PT’s need to address the fear and “SELL” the treatment

Changes their belief and perception of movement

23
Q

Variable techniques depend on ____ and ____

A

Variable techniques depending on goal of the TX and irritability of symptoms

24
Q

Grades of Mobilization

A

Grade 1: Small Oscillations/Beginning Range
Grade 2: Large Oscillations/Beg to Mid
Grade 3: Large Oscillations/Mid to end
Grade 4: Small Oscillations/End range

25
Q

Important considerations for all joint mobilization techniques:

A
  • Consider the arthrokinematics of the joint if necessary (convex on concave OR concave on convex) to consider the appropriate direction of force for arthrokinematic mobilization techniques
  • Place patient in appropriate position with proximal segment of the joint stable
  • Provide maximal support of the distal segment of the joint
  • If performing arthrokinematic motions (glide, rotation, etc)
    o ELBOW must be in line with direction of force
    o Use as much surface contact with the mobilizing hand as possible while still providing the force in the appropriate direction
    o Mobilizing hand must be as close to the joint axis as possible
    o Provide force through the trunk (with UE locked into trunk) as much as possible
  • ALWAYS explain to the patient what you are doing and the clinic rationale
  • GAIN CONSENT FROM THE PATIENT
  • Ask for patient feedback while you are doing the technique
    o Gauge pressure, hand placement, intensity of pain
26
Q

NON-THRUST MOBILIZATION: LOW GRADE MOBILIZATION (I-II)

A
  • Goals: Decrease pain by stimulation of mechanoreceptors and relaxation of tense musculature
  • Performed in beginning range or mid range of available joint motion(Beginning to R1)
  • High irritability of symptoms (intensity, how much to provoke, and how long to resolve)
  • Grade I: Small amplitude oscillatory movement at the beginning of motion
  • Grade II: Large amplitude oscillatory movement within mid-range of motion (Beginning to R1)
  • Often performed in open pack position of joint

Early in ROM or not engaging the capsular barrier

Open pack: Joint capsule on slack; more joint gliding.

27
Q

NON-THRUST MOBILIZATION: HIGH GRADE MOBILIZATION (III-IV)

A
  • Goal: Stress to joint capsule to achieve greater stimulation of mechanoreceptors and possible soft tissue stretching
  • Performed toward end range of available joint motion
  • Low irritability of symptoms
  • Grade III: Large amplitude oscillatory movement from mid-range to end range (R1 to R2) of motion
  • Grade IV: Small amplitude oscillatory movement at to end range of motion (End of R2)
  • Progress to closed pack position of joint
28
Q

Open Pack (Loose Pack)

A
  • Any other position other than closed pack
  • Decreased joint congruity and joint surface contact
  • Ligaments are on slack
  • Maximal joint volume
  • Minimal joint stability
29
Q

Closed Pack

A
  • Maximal joint congruency
  • Ligaments are maximally taught
  • Maximal stability of the joint
  • Minimized joint volume
  • Increased compressive forces of the joint

Don’t use on high irritabiltiy

30
Q

Stages of Irritability and Joint Mobilization Selection

A

High Irritabiltiy = Low Grades of Mobilization (open pack)
Moderate irritability = Low to High Grades (open to closed pack)
Low Irritability = High Grade (closed pack)

31
Q

THRUST MOBILIZATION

aka Manipulation

A
  • Much more of a neurophysiological response
  • Goal: Intended to provide a neurophysiologic response as described earlier
  • Not necessarily a continuum from the other grades
  • High velocity, low amplitude thrust technique at mid to end range of motion
  • May be associated with a “pop”, however, not needed for effectiveness (does not dictate effectiveness in joint to have good outcomes)
  • Defined group of patients benefit most from thrust mobilization
  • #1 indicator: acuity (acuteness) of symptoms
  • #2 indicator: NON-RADIATING symptoms (nociceptive)
  • Neurophysiological
    – Reduction in muscle tone, muscle guarding, patient fear, patient guarding, more allowance of motion as a result of central processing in the brain.

Big low amplitude force to joint is best predictor to good outcomes

Don’t have to build up to get to a thrust

32
Q

What terms can you NOT use?

A

Adjustment and spinal subluxation

PT’s use thrust mobilization to address pain and mobility limitations.

33
Q

Documenting Mobilizations

A
  • Patient position(if appropriate, position of extremity: closed pack or loose pack)
  • Thrust vs. non-thrust (if non-thrust: grade?)
  • Direction of force
  • Body region that the forces is applied to

Position; Grade; Direction; Range of movement

Example: Supine Grade III-IV non-thrust mobilization in anterior to posterior (AP) direction to mid-thoracic spine
OR
Supine Grade III-IV non-thrust AP mob to mid thoracic

34
