Description

Of the Finger Trainer is a therapeutic electro-mechanical exercise device for the hand and human fingers mainly for movement problems strokes or accidents. It is a requirement that the fingers and the hand essentially Unharmed and so stable that they withstand these exercises. By the Training of the hand and its fingers with the finger trainer is intended their mobility, coordination and sensitivity are improved.

The Treatment of severe upper limb weakness, e.g. after stroke is difficult and often unsuccessful. conventional Person-intensive physiotherapy aims mostly at spasticity To release muscle cramps and the proximal anchoring of the paralyzed limb by means of invigoration the trunk and shoulder girdle muscles to stabilize. As a consequence, this procedure leads in practice often to that the Patient does not repeatedly exercise hand and finger movements. modern By contrast, scientific concepts favor a repeated one passive and as far as possible active practice individual movement sequences preferred by hand or forearm. So could for Stroke patients are shown to be repeated active, isometric and isotonic dorsal extension of the wrist for regression the motor function of the entire upper limb one superior to conventional therapy was. Regarding active movements of paralyzed or handicapped extremity sections It should be noted that they are for get one the mobility of the motion segment and the other keep the memory of the brain in motion.

In the DE GM 29906578 "Therapy device" is a device for training the fingers of a spastic paralyzed hand, which is characterized by several on a shaft 4 arranged cam-shaped elevations 5 . 6 . 7 . 8th whose Umpfangsflächen serve as finger pads for periodically raising and opening the fingers.

The disadvantage of the "therapy device" as in DE GM 29906578 is explained that in the mechanical active movement mainly stiff and handicapped fingers despite fixation of the hand fingers not the movement of the cam-shaped elevations 5 . 6 . 7 . 8th and essentially often remain at the highest cam position while the cams spin uselessly under the fingers. The sole exercise of the fingers with the therapy device is another disadvantage, since further stimuli to improve the healing success with the device described do not affect the fingers and the hand. Due to the rigid position of the cams to each other, the therapy is also always monotone.

task The invention is to provide a device with which the Fingers on the edge of a patient mainly look for movement problems strokes or accidents so practiced can be that the exercises variable according to medical and psychological criteria freely changeable are. Besides therapy not only mechanical Movement of the fingers but also other helpful stimuli healing success for the patient produce. It can be achieved in the active movement of the mostly rigid fingers, they still follow the exercise movement. finger should thus on the one hand by the frequent repetition of exercise elements and, on the other hand, through the transmission of learning effects for the weakened extremity allows become.

According to the invention Task to create a finger trainer for the hand and fingers of one Patients with movement problems, thereby achieving that on one Base plate driven by a rotary drive eccentric shaft with individual extensions for the respective fingers of the hand is arranged. About the individual Exentern the Exenterwelle are elastically resilient Fingerniederhalter, where spring clip connect the finger retainers to the base plate. Parallel to the Eccentric shaft over the base plate runs a thumb rest.

In the base plate with the entire device on it the finger trainer takes an initiation of vibrations.

The individual eccentric have a concave Umpfangsform adapted to the fingers. On this surface There are various variable and interchangeable pimples.

It is appropriate that the individual eccentric on the eccentric shaft to each other in their Exenterstellung are adjustable.

The finger trainer has the following function:
The fingers of the hand are placed between the eccentric shaft and the elastically depressing finger retainers on the individual eccentric with their fingers adapted concave surfaces. The thumb hooks around the thumb holder and fixes the hand, which lies on a cushion for a more comfortable and safe therapy. The rotation of the eccentric shaft moves the fingers mainly in different up and down movements, depending on the position of the Exenter each other. Vibrations and the pimples on the exteriors are supposed to stimulate the nerve activity in the hand during movement of the fingers through the eccentric shaft Stimulate fingers and thus improve the possibility of movement, coordination and sensitivity. Likewise, resulting learning effects can promote a cure.

One embodiment is explained in the following drawings. It shows:

1 : the finger trainer with the hand up, fingers of the patient 11 ,

2 : the finger trainer without the laid hand, fingers of the patient 11 ,

3 : the finger trainer without the laid hand, fingers of the patient 11 , There are also the finger depressor 5 with their spring clips 6 not shown.

According to the 1 consists of the finger trainer, for the hand and fingers of a patient 11 with movement problems, from a base plate 1 on the one by a rotary drive 4 driven eccentric shaft 2 with individual exenters 3 for the respective fingers 11 is arranged.

About the individual Exentern 3 the eccentric shaft 2 are elastically yielding finger depressor 5 , where spring clip 6 the finger depressor 5 with the base plate 1 connect. Parallel in front of the eccentric shaft 2 above the base plate 1 runs a thumb holder 7 ,

Also in the 1 is the introduction of vibrations in the base plate 1 marked with the entire device of the finger trainer.

The clearest is from the 3 recognizable, that the individual Exenter 3 one's fingers 11 have adapted concave Umpfangsform and on this surface are various variable and replaceable knobs 12 are located.

It is appropriate that the individual Exenter 3 on the eccentric shaft 2 mutually adjustable in their Exenterstellung.
