Joint mobilization AmiR
This document defines joint mobilization techniques and provides guidelines for their use. It describes mobilization as a manual therapy that uses passive joint movement to increase range of motion or decrease pain. Accessory joint movements like gliding and traction are explained. Precautions and contraindications for mobilization are outlined. A grading scale from I to V is presented to indicate the amplitude of oscillations used in different mobilization techniques.

- 3. Objectives At the endof this lecture students will be able to • Define mobilization, Self-Mobilization, Mobilization with Movement, physiologic movements, accessory movements, arthrokinematics, muscle energy, thrust, convex & concave surface, • Describe Joint Shapes & Arthrokinematics • Explain Convex-Concave & Concave-Convex Rule • Describe Effects of Joint Mobilization • Enumerate precautions & Contraindications for Mobilization • Describe Maitland Joint Mobilization Grading Scale
- 4. What is JointMobilization? • Manual therapy technique – Used to modulate pain – Used to increase ROM – Used to treat joint dysfunctions that limit ROM by specifically addressing altered joint mechanics
- 5. • Factors thatmay alter joint mechanics: – Pain & Muscle guarding – Joint hypomobility – Joint effusion – Contractures or adhesions in the joint capsules or supporting ligaments – Malalignment or subluxation of bony surfaces
- 6. Terminology • Mobilization – passivejoint movement for increasing ROM or decreasing pain – Applied to joints & related soft tissues at varying speeds & amplitudes using physiologic or accessory motions – Force is light enough that patient’s can stop the movement • Manipulation – passive joint movement for increasing joint mobility – Incorporates a sudden, forceful thrust that is beyond the patient’s control
- 7. Terminology • Self-Mobilization (Auto-mobilization) –self-stretching techniques that specifically use joint traction or glides that direct the stretch force to the joint capsule • Mobilization with Movement (MWM) – Concurrent application of a sustained accessory mobilization applied by a clinician, Physiotherapist to end range and physiological movement applied by the patient – Applied in a pain-free direction
- 8. Terminology • Physiologic Movements –movements done voluntarily – Movements such as flexion, extension, abduction, rotation – Osteokinematics • motions of the bones • Arthrokinematics – motions of bone surfaces within the joint . – Also called joint play – 5 motions • Roll, Slide, Spin, Compression, Distraction
- 9. Accessory Movements – Movementswithin the joint & surrounding tissues that are necessary for normal ROM, but can not be voluntarily performed – Component motions • motions that accompany active motion, but are not under voluntary control • Ex: Upward rotation of scapula & rotation of clavicle that occur with shoulder flexion – Joint play • motions that occur within the joint • Determined by joint capsule’s laxity • Can be demonstrated passively, but not performed actively
- 10. Terminology • Muscle energy –use an active contraction of deep muscles that attach near the joint & whose line of pull can cause the desired accessory motion – Clinician stabilizes segment on which the distal aspect of the muscle attaches; command for an isometric contraction of the muscle is given, which causes the accessory movement of the joint
- 11. Terminology • Thrust – high-velocity,short-amplitude motion that the patient can not prevent – Performed at end of pathologic limit of the joint (snap adhesions, stimulate joint receptors) • Concave – hollowed or rounded inward • Convex – curved or rounded outward
- 12. Relationship Between Physiological& Accessory Motion • Biomechanics of joint motion – Physiological motion • Result of concentric or eccentric active muscle contractions • flexion, extension, abduction, adduction or rotation – Accessory Motion • Motion of articular surfaces relative to one another • Generally associated with physiological movement • Necessary for full range of physiological motion to occur • Ligament & joint capsule involvement in motion
- 13. Joint Shapes • Ovoid –one surface is convex, other surface is concave – E.g. hip joint • Sellar (saddle) – one surface is concave in one direction & convex in the other, with the opposing surface convex & concave respectively – Subtalar joint
- 14. Basic concepts ofjoint motion : Arthrokinematics Types of joint motion • 5 types of joint arthrokinematics – Roll – Slide – Spin – Compression – Distraction • Joint motion usually often involves a combination of rolling, sliding & spinning
- 15. Roll • A seriesof points on one articulating surface come into contact with a series of points on another surface – ball rolling on ground – Example: Femoral condyles rolling on tibial plateau – Roll occurs in direction of movement – Occurs on incongruent (unequal) surfaces – Usually occurs in combination with sliding or spinning
- 16. Slide • Specific pointon one surface comes into contact with a series of points on another surface • Surfaces are congruent • When a passive mobilization technique is applied to produce a slide in the joint – referred to as a GLIDE. • Combined rolling-sliding in a joint – The more congruent the surfaces are, the more sliding there is – The more incongruent the joint surfaces are, the more rolling there is
- 17. Spin • Occurs whenone bone rotates around a stationary longitudinal mechanical axis – Same point on the moving surface creates an arc of a circle as the bone spins • Example: Shoulder with flexion/extension, the hip with flexion/extension, and Radial head at the humeroradial joint during pronation/supination
- 18. • Compression – Decreasein space between two joint surfaces – Adds stability to a joint – Normal reaction of a joint to muscle contraction • Distraction – Two surfaces are pulled apart – Often used in combination with joint mobilizations to increase stretch of capsule.
- 19. Convex-Concave & Concave-ConvexRule • Basic application of correct mobilization techniques • One joint surface is MOBILE & one is STABLE • Concave-convex rule: concave joint surfaces slide in the SAME direction as the bone movement (convex is STABLE) – If concave joint is moving on stationary convex surface – glide occurs in same direction as roll
- 20. Convex-concave rule: convexjoint surfaces slide in the OPPOSITE direction of the bone movement (concave is STABLE) If convex surface in moving on stationary concave surface – gliding occurs in opposite direction to roll
- 22. Effects of JointMobilization • Neurophysiological effects – Stimulates mechanoreceptors to pain – Affect muscle spasm & muscle guarding – nociceptive stimulation – Increase in awareness of position & motion because of afferent nerve impulses • Nutritional effects – Distraction or small gliding movements – cause synovial fluid movement – Movement can improve nutrient exchange
- 23. • Mechanical effects –Improve mobility of hypo-mobile joints (adhesions & thickened Connective tissue from immobilization – loosens) – Maintains extensibility & tensile strength of articular tissues
- 24. Contraindications for Mobilization • Avoidthe following: – Inflammatory arthritis – Malignancy – Tuberculosis – Osteoporosis – Ligamentous rupture – Herniated disks with nerve compression – Bone disease – Neurological involvement – Bone fracture – Congenital bone deformities – Vascular disorders – Joint effusion • May use I & II mobilizations to relieve pain
- 25. Precautions • Osteoarthritis • Pregnancy •Total joint replacement • Severe scoliosis • Poor general health • Patient’s inability to relax
- 26. Articulating Techniques (Maitland) Articulations aregraded oscillations, used to restore joint play, component motion, or range of motion in a hypo-mobile joint. The extent of accessory movement from beginning to end of range.
- 27. Grades for NormalRange
- 28. Grade I Oscillation •Small amplitude movement – start of resistance (R1) at the beginning of range of movement • Gentle oscillation used for pain relief • Requires great control to remain within the required small amplitude
- 29. Grade II Oscillation •Largeamplitude movement – start of resistance (R1) within midrange of movement •Can occupy any part of the range that is free of any stiffness or spasm •Never reach into resistance, always resistance- free movements
- 30. Grade III Oscillations •Large amplitude movement to mid-point of resistance (50% of R1 – R2) up to point of limit of the available motion • Move from R1 to half way between R1 and R2
- 31. Grade IV Oscillations •Small amplitude movement to the mid-point of resistance– between R1 and R2 at very end range of movement • Oscillatory movement often stretching into stiffness or spasm
- 32. Grade V Oscillations •Small amplitude, high velocity thrust at the end of motion – at R2 • Single thrust once patient is correctly positioned – may or may not be an audible associated • Manipulations include the same techniques as articulations but incorporate a high velocity thrust. • The thrust is usually a short arc at the end of the available range of motion, i.e at or close to R2.
- 33. Grades for NormalRange
- 35. Indications for Mobilization •Grades I and II – primarily used for pain – Pain must be treated prior to stiffness – Painful conditions can be treated daily – Small amplitude oscillations stimulate mechanoreceptors - limit pain perception • Grades III and IV – primarily used to increase motion – Stiff or hypomobile joints should be treated 3-4 times per week – alternate with active motion exercises
- 36. Joint Positions • Restingposition – Maximum joint play - position in which joint capsule and ligaments are most relaxed – Evaluation and treatment position utilized with hypomobile joints • Loose-packed position – Articulating surfaces are maximally separated – Joint will exhibit greatest amount of joint play – Position used for both traction and joint mobilization
- 37. • Close-packed position –Jointsurfaces are in maximal contact to each other • General rule: – Extremes of joint motion are close-packed, & midrange positions are loose-packed.
- 38. Joint Mobilization Application •All joint mobilizations follow the convex- concave rule • Patient should be relaxed • Explain purpose of treatment & sensations to expect to patient • Evaluate BEFORE & AFTER treatment goniometry
- 39. • Stop thetreatment if it is too painful for the patient • Use proper body mechanics • Use gravity to assist the mobilization technique if possible • Begin & end treatments with Grade I or II oscillations
- 40. Positioning & Stabilization •Patient & extremity should be positioned so that the patient can RELAX • Initial mobilization is performed in a loose- packed position – In some cases, the position to use is the one in which the joint is least painful
- 41. • Firmly &comfortably stabilize one joint segment, usually the proximal bone – Hand, belt, assistant – Prevents unwanted stress & makes the stretch force more specific & effective
- 42. Treatment Force &Direction of Movement • Treatment force is applied as close to the opposing joint surface as possible • The larger the contact surface is, the more comfortable the procedure will be (e.g. use flat surface of the hand instead of forcing with the thumb) • Direction of movement during treatment is either PARALLEL or PERPENDICULAR to the treatment plane
- 43. Treatment Direction • Treatmentplane lies on the concave articulating surface, perpendicular to a line from the center of the convex articulating surface • Joint traction techniques are applied perpendicular to the treatment plane – Entire bone is moved so that the joint surfaces are separated
- 45. • Gliding techniquesare applied parallel to the treatment plane • Glide in the direction in which the slide would normally occur for the desired motion • Direction of sliding is easily determined by using the convex-concave rule. The entire bone is moved so that there is gliding of one joint surface on the other. • The bone should not be used as a lever; it should have no arcing motion (swing) that would cause rolling and thus compression of the joint surfaces.
- 46. • When usinggrade III gliding techniques, a grade I distraction should be used • If gliding in the restricted direction is too painful, begin gliding mobilizations in the painless direction then progress to gliding in restricted direction when not as painful
- 47. • Reevaluate thejoint response the next day or have the patient report at the next visit – If increased pain, reduce amplitude of oscillations – If joint is the same or better, perform either of the following: • Repeat the same maneuver if goal is to maintain joint play • Progress to sustained grade III traction or glides if the goal is to increase joint play
