What is the Convex–Concave Rule?
Conclusion The convex–concave rule, introduced by Kaltenborn into manual therapy, is a didactic simplification of the lever law, during rotatory movements of the joints. Movement of a convex bone corresponds to movement of a lever with two arms (=convex rule) and movement of a concave bone to a movement of a lever with one arm (=concave rule).
What is the convex-concave rule in joint mobilization gliding?
The convex-concave rule is the basis for determining the direction of the mobilizing force when joint mobilization gliding techniques are used to increase a certain joint motion. The direction in which sliding occurs depends on whether the moving surface is concave or convex.
Do convex-concave rules apply to glenohumeral joints?
I don't think so, which is the topic of this editorial. One common example of the application of the convex-concave rules is the arthrokinematics of abduction of the glenohumeral (GH) joint: the convex humeral head rolls superior relative to the glenoid fossa as a point on its articular surface simultaneously slides inferior.
Is the trapezoid concave or convex?
The triangular, distal surface of the trapezoid is convex in the transverse plane and concave coronally, ‘cupping’ a concave groove on the second metacarpal base. A deep ridge medial to this groove articulates with the concave, anterolateral corner of the capitate bone.
Introduction
'Arthrokinematics' refers to the movement of joint surfaces. Arthrokinematics differs from Osteokinematics- in general Osteokinematics means joint movement and Arthrokinematics joint surface motion. The angular movement of bones in the human body occurs as a result of a combination of rolls, spins, and slides. 1. A roll is a rotary movement, one bo
Types of Arthrokinematic Motion
Joint Play: movement not under voluntary control (passive), can not be achieved by active muscular contraction.Component Movement: involuntary obligatory joint motion occurring outside the joint accompanies active motion – i.e. - scapulohumeral rhythm physio-pedia.com

Which femur is convex or concave?
It is CONVEX (domed), when the humerus moves in abduction, the surface of the humeral head will slide in the OPPOSITE direction to the movement of the humerus. (bottom articulation of picture 2) The distal femur is convex, its articulates on the tibia which is concave (due to meniscus). Take the bone which is moving, in this case its the tibia.
What is the denition of a convex function?
Let's rst recall the denition of a convex function. In words, this means that if we take any two pointsx; y, thenfevaluated at any convexcombination of these two points should be no larger than the same convex combinationoff(x) andf(y). Geometrically, the line segment connecting (x; f(x)) to (y; f(y)) must sit above thegraph off.
Which direction does sliding occur if a joint is concave or convex?
The direction in which sliding occurs depends on whether the moving surface is concave or convex. If the moving joint surface is CONVEX, sliding is in the OPPOSITE direction of the angular movement of the bone.
What is the difference between concave and convex?
Neither word is particularly recent; concave has been in English since the 15th century, and convex since the 16th. Make a holowe case of sylver, after the fashion of a concave glasse, outwardly laboured with curious art of gravyng, not onely for ornament, but also for lyghtnesse.
