week 10 Translatoric joint play, Grades of Kaltenborn and Cocave-convex rule

Translatoric Joint Play:

¨In every joint there are positions in which looseness or slack in the capsule and ligaments allows small, precise movements of joint play to occur as a consequence of internal and external (e.g.,passive) movement forces on the body.

These joint play movements are an accessory movements not under voluntary control, and are essential to the easy, painless performance of active movement.

The Kaltenborn Convex-Concave Rule is a familiar concept in manual therapy joint techniques and arthrokinematics. The rule is based on the relationship between normal bone rotations and the gliding component of the corresponding joint movements.

The Kaltenborn Convex-Concave Rule

When a convex joint surface is moving, the roll and glide occur in the opposite direction. The therapist moves a convex joint surface opposite to the direction of restricted movement to provoke the capsule in the same direction as the glide. 

When a concave joint surface is moving the roll and the glide occur in the same direction. The therapist moves a concave joint surface in the same direction as the direction of the restricted movement. The opposite capsule is provoked.

 Kaltenborn treatment plan

The Kaltenborn treatment plan is important to define the directions of tractions and glides. The plane is situated on the concave articular surface and remains with the concave joint surface whether the moving joint partner is concave or convex.
