- 3. 3 continuing ED Osteokinematics observable movements of bones in space as represented by a change in the angle of adjacent articular segments āMotion You SEEā continuing ED Arthrokinematics āMotion You FEELā ā¢ Unobservable articular accessory motion between adjacent joint surfaces Ā¾ roll, glide, and spin ā¢ These accessory motions take place with all active and passive movements and are necessary for full, pain free range of motion ā¢ Arthrokinematic motion can not occur indepen- dently or voluntarily and if restricted, can limit physiological movement
- 4. 4 continuing ED Types of Arthrokinematic Motion Joint Play Ā¾ movement not under voluntary control (passive) Ā¾ can not be achieved by active muscular contraction versus Component Movement Ā¾ involuntary obligatory joint motion occurring outside the joint accompanies active motion ā i.e. - scapulohumeral rhythm continuing ED Arthrokinematic ROLL ā¢ new points on one surface come into contact with new points on the other surface (wheel) ā¢ rolling only occurs when the two articulating surfaces are incongruent
- 5. 5 continuing ED Arthrokinematic GLIDE ā¢ translatory motion in which one constant point on one surface is contacting new points or a series of points on the other surface ā¢ pure gliding can occur when two surfaces are congruent and flat or congruent and curved ā¢ glide also referred to as translation braking analogy continuing ED Arthrokinematic SPIN ā¢ rotation around a longitudinal stationary mechanical axis (one point of contact) in a CW or CCW direction loss of traction analogy
- 6. 6 continuing ED Arthrokinematic Motions Concave on Convex continuing ED Arthrokinematic Motions Convex on Concave
- 7. 7 continuing ED ROLLING and GLIDING ā¢ Since there is never pure congruency between joint surfaces; all motions require rolling and gliding to occur simultaneously ā¢ This combination of roll and glide is simultaneous but not necessarily in proportion to one another continuing ED Arthrokinematic Motions The more congruent - the more the gliding The more incongruent - the more the rolling B A 3 2 1 Pure Spin: B contacts point 1 x
- 8. 8 continuing ED Arthrokinematic Motions The more congruent - the more the gliding The more incongruent - the more the rolling B A 3 2 1 Pure Glide: A contacts point 2 x A continuing ED Arthrokinematic Motions The more congruent - the more the gliding The more incongruent - the more the rolling B A 3 2 1 x Pure Roll: B contacts point 3 B
- 9. 9 continuing ED Arthrokinematic Motions The more congruent - the more the gliding The more incongruent - the more the rolling B A 3 2 1 x B Glide and Roll: B contacts point 2 continuing ED Objective 2 Explain the arthrokinematic rules of motion
- 10. 10 continuing ED Joint Morphology Joint surfaces are defined as: Convex: male; rounded or arched Concave: female; hollowed or shallow continuing ED Joint Morphology Joint surfaces are defined as: Ovoid: concave and convex articular partner surface Sellar: saddle shape with each articular surface having a concave and convex component in a specific direction ā¢ Examples would include the sternoclavicular and 1st carpometacarpal joints
- 11. 11 continuing ED Concave and Convex Characteristics ā¢ convex surfaces have more cartilage at the center ā¢ concave surfaces have more cartilage on the periphery ā¢ where surfaces appear flat - the larger articular surface is considered convex continuing ED Rules of Motion Concave Motion Rule ā¢ convex surface is stationary and concave surface moves ā¢ osteo and arthrokinematic motion is in the same direction ā¢ arthrokinematic mobilization gliding force is in the same direction as osteokinematic bony movement GLIDE and ROLL are in the SAME DIRECTION
- 12. 12 continuing ED Rules of Motion Convex Motion Rule ā¢ concave surface is stationary and convex surface moves ā¢ osteo and arthrokinematic motion is in the opposite direction ā¢ arthrokinematic mobilization gliding force is in the opposite direction as osteokinematic bony movement GLIDE and ROLL are in the OPPOSITE DIRECTION continuing ED Rules of Motion femur stationary tibia stationary ā¢ because their is always incongruent surfaces, there must be some combination of glide and roll ā¢ arthrokinematic roll always occurs in the same direction as bony movement regardless of whether the joint surface is convex or concave in shape.
- 13. 13 continuing ED Functional Roll and Glide Analogy The more congruent ā the more glide The more incongruent ā the more roll Joint incongruency requires rolling and gliding in combination continuing ED Obligate Translation ā¢ During AROM translation direction is influenced by the capsuloligamentous complex ā¢ Passive restraints act not only to restrict movement but also to reverse articular movements at the end range of motion Convex-Concave Morphology vs. Capsular Obligate Translation ā¢ At end range, asymmetrical capsular mobility causes obligate translation away from the side of tightness ā¢ Tight capsular structures will cause early and excessive accessory motion in the opposite direction of the tightness
- 14. 14 continuing ED secondary to capsular tightness asymmetry continuing ED Treatment Plane and Axis of Motion The treatment plane lies in the concave articular surface and is parallel to the joint surface and perpendicular to the axis in the convex surface The axis of motion always lies in the convex articular surface The treatment plane moves with the concave surface moves The treatment plane remains essentially still when the convex surface moves
- 15. 15 continuing ED TRACTION ā¢ the process of pulling one bony surface away from the other (joint separation) ā¢ passive translatoric bone movement which is at a right angle to the treatment plane continuing ED GLIDING ā¢ Translatory movement where the joint surfaces are passively displaced parallel to the treatment plane
