The object of the invention is therefore to improve the prior art device and to expand.

According to the invention this object is achieved in that the adjustable at the end of the rope is fixed to the housing.

By adjusting the other end of the rope, the stroke of the carrier supporting the finger sleeves can be changed within the guides and thus adapted to the individual requirements of the patient to be treated.

Preferably, the other end of the rope is attached to a guide piece which is slidably mounted and lockable in a housing-fixed guide. The housing-fixed guide preferably consists of a bore with a longitudinal slot, which is penetrated by a bolt connected to the guide piece on which a locking nut can be screwed.

The guide may be arranged substantially parallel to the levers and preferably at their height at the top of the housing. As a result, the guide and possibly the associated adjustment and locking means for the operator are easily accessible.

Preferably, the cable is guided between the second roller and the other housing-fixed end around a housing-fixed, cylindrical body, which in turn is preferably arcuately curved. As a result, the otherwise required role is replaced by the housing-fixed, cylindrical body, which brings a considerable simplification and increase the reliability with it.

The eccentric cams can be supported on the levers via roller bearings, preferably ball bearings, whereby the friction is reduced.

Preferably, the guides in the levers consist of an axial bore of the levers and the levers on their upper side are provided with a longitudinal slot which cuts the bore over a central part of its length.

According to a further advantageous embodiment, the carrier-forming bolts are guided axially displaceably in the holes and are fastened laterally on the bolts, the slots passing through pins which carry the finger sleeves.

It is advantageous if five levers are provided, the rear ends of which extend parallel to one another and whose front ends, starting from the straight central lever, are angled in a fan-like manner relative to one another. Depending on whether the left or right hand is being treated, the outer left or outer right finger sleeve remains free.

A particularly good processing of the fingers is achieved when the eccentric cams are mounted twisted on their shafts to each other, so that the up and down movement of the lever is out of phase with each other.

The invention further relates to a device for gymnastic treatment of the finger joints with a housing. To solve the task of extending such a device in its therapeutic possibilities, a spreader is provided with at least one preferably semi-cylindrical recess finger pads, which are rotatably driven about a vertical axis. The fingers are placed on the fingers. The spreader twists the finger pads, so that the fingers are spread.
