Description
~L3~7~
The present invention relates to the re-education of free articulation of the articulated segments of the hand, namely in particular, the metacarpophalangeal articula-tions, and the proximal and distal interphalangeal articulations, not excluding however the wrist articulation in general, considered according to the invention, as forming also part of the hand.
The recovery of the freedom of articu-lation and of angular amplitude of the articulated segments of the hand, after fractures or surgical interventions is, as we know, essentially dependent on the possibility of restoring the mobility of the affected articulated segments. Such a re-education has always necessitated the services of a specialist, such as a kinototherapist, mainly because of the special ana-tomical nature of the hand.
The prior technique has, up to now,offered no really satisfactory apparatus capable of replacing the manual intervention and capable of adjustably training the articulated segments to move, whilst taking into account the anatomical and physiological nature of the hand.
It is precisely an object of an aspect of the invention to fill this gap by proposing an appa-ratus for re-educating by restoring mobility, which is par-ticularly adapted to the anatomical characteristics of the articulated segments of the hand. The object of the invention is designed so as to be automatically adjustable and adaptable for training one or more articulated segments without the intervention of a practitioner.
The invention proposes to this effect an apparatus which, by its design and adaptability, permits a phase of post-operative training, if only a passive one, to at least some of the articulated segments of the hand, without any risk of any violent and traumatizing strain.

Referring first to Figure 1, this shows a hand in a stretched state in which the different fingers and the palm extend inside a plan Z-2'. In this state, , ~L3~7~9~
the di~ferent parts of the skeleton of the hand, namely the metacarpals, phalanges, middle phalan~ and distal phalanx, are aligned inside said plane Z-Z'. It may also be considered, in this particular state, -that the articulations of the longer fingers, namely the meta-carpophalangeal(MP) articulat:ions, the proximal inter-phalangeal (PI) articulations and the distal inter-phalangeal (DI) articulations, are also aligned inside the same plane. For every longer finyer, the total length L
represents the distance separating an MP articulation from the point PX corresponding to the end of the considered finger.
The bending control of the fingers, in the direction of arrow fl, results first in an urging of the MP articulations, then, progressively and dependlng on the angular amplitude which is reached, by an urging of the IP articulations and finally, by an urging o the ID articulations.
Thus, as the bending movement progresses in the direction of arrow fl, the distance separating, for every finger, the MP articulation from the point PX
reduces, taking, for one reference finger, the value L2 in a virtually fully bent state.
It is clear from figure 1 that the successive urging of the different articulations results in a progressive bending represented by a curve LX which somewhat resembles a spiral.
A mobility-restoring and re-education apparatus must therefore take this physiological particul-arity into account in order to be able to move, if only passively, the articulated segments of the hand and of the longer fingers.
The apparatus according to the invention is designed to meet this requirement.
In the first embodiment illustrated in Figures 2 to 5, the mobility-restoring apparatus comprises ~3~8~
a drive member 1, preferably constituted by an electrical motor-reducer group mounted in a support, casing or hous-ing 2 carried by a structure 3. sy way of example, the structure 3 can be constituted by an underframe ~ on which is fixed by way of an adjusting jaw 5, a system 6 of adjustable bars carrying a support cradle 7 for the forearm.
The electric motor 1 is of the type with two directions of rotation and its supply is controlled by a general control switch, not shown in the drawings, as well as by two end-o~-stroke reversing contactors 8a, 8b, adjustable in position. Said contactors 8a-8b are accessible from the outside of casing 2 and can be adjusted correspondingly to one or more dials or scales bearing graduations representing angular amplitudes. The reversing contactors are designed to be actuated by way of a movable member, schematized in 9 in Figure 2, carried by at least one driving shaft 10 of the motor 1.
Figure 3 shows that motor 1 could be selected to comprise two diametrically opposite driving shafts 10 and lOa, thus offering a reversible possibility of adapting the different members constituting the apparatus, such as described hereinafter.
The driving shaft 10 supports, extern-ally to casing 1, a slide-guide 11, wedged at an angle on the driving shaft by any suitable means. Said slide-guide is mounted so as to e~tend in the direction opposite the cradle 7 with respect to shaft 10.
Slide-guide 11, illustrated in more details in Figures 4 and 5, is for example, produced in the form of a bar 12 forming or comprising means 13 of supporting and linearly guiding a slide-block 13, which is movable in centripetal or centrifugal manner, a radial rectilinear direction with respect to shaft 10.
~3~'751~4 Said support and rectilinear guiding means can be of various types. For example, the bar 12 can define an opening 14 which extends in parallel to the longitudinal axis of the rule to cooperate with a complementary counterpart provided on the slide-block. It is also possible Eor the slide-block to be mounted on at least one guide rod 15.
Guide-block 13 is permanently urged in centrifugal movement by a return member 16, preferably an elastic member~ In the illustrated example, the elastic member 16 is constituted by a helical spring working under compression, and mounted concentrically on rod 15. The spring is tensioned between the slide-block 13 and an abutment 17 formed by an extended portion 18 of the bar 12. Said abutment 17 also acts as a support for the rod 15.
The bar 12 comprises, between the abutment 17 and opening 14, a bearing or sleeve 19 for positioning and angular locking on driving shaft 10.
Different technical means can be used to fulfil this function and for example, as illustrated in Figure 5, the sleeve 1~ can comprise two diametrically opposite flat portions, designed to cooperate with cumplementary flat portions provided on the shaft 10.
The slide-block 13 supports a piece 20 carrying a small bar 21 which extends in parallel to shaft 10. Small bar 21 is preferably adjustable in extension, for example by means of a locking screw 22.
The pieoe20 is mounted on slide-block 13 through an opening 23 through which is threaded a pin 24 rising from the slide-block and provided with a tightening member 250 Opening 23 is so provided as to extend in parallel to the axis of opening 14. Longitudinal guiding means are provided between piece 20 and slide-block 13. Such means can be constituted by flanges 26 extending the 3~3~7~8~
piece 20 downwardly to cooperate with the side faces of slide-hlock 13.
Slide-block 13 is also operationally coupled to means 27 designed to cause its centripetal movement on the bar 12, in relation to the angular movement of the slide-guide by the shaft 10, in the direction of arrow fl. The means 27 comprise ,first of all, at least one flexible but non-extendable cable or wire 28. Said cable is fastened between, substantially, the axis of the sleeve 19 and the slide-block 13, in such a way as to be able to extend laterally to the slide-guide 12 and externally thereto. The means 27 further comprise a cam 29 secured on the bearing struc-ture, in such a way that its plane coincides with the plane in which said cable or wire 2B moves, during the angular movement of slide-guide 12. In the illustrated example, the cam 29 is secured on the casing or housing 2.
Said cam 29 has a profile which is such that the winding of the cable imparts a centripetal movement to slide-blo~k 13 according to a law such that the small bar 21 follows a resultant path comparable to curve LX described in reference to Figure 1.
The apparatus according to the invention further comprises a bearing support 31 consti-tuted by a rigid rod secured to the periphery of a ring 32 adapted to be mounted with a possibility of rotation on the end part of shaft 10 which projects from sleeve 19.
Said rod 31 is designed to extend in parallel to shaft 10 and to small bar 21~
The apparatus such as described herein- .i above can be used in many different ways. According to the illustrated example, the relative adaptation of the different elements constituting the apparatus is designed for an appl:ication as a means of re-educating or mobiliz-ing segments of the right hand.
~3~7913~
The cradle 7 is adjusted in positionso that the forearm of the patient can rest thereon and that the hand can rest by the palm on bearing support 31 placed approximately plumb with the different ~P artic-ulations of the longer fingers. Piece 20 is so adjustedon slide-block 13 as to bring small bar 21 substantially close to the point PX of the longest finger in stretched position.
The use of the apparatus then calls on joining means between sma:Ll bar 21 and for example, the assembly of longer fingers to be moved. Figure 6 shows that such means, designated as a whole by reference 33, can comprise a net 34 shaped as a sleeve through which the longer fingers are introduced. The free end of said sleeve 34, which extends beyond the fingers, is folded over the small bar 21 and held thereon by a clip member 35.
The contactors 8a and 8b are then adjusted so as to determine the angular movement amplitude to be given to the slide-guide 12. Such an ampli-tude may be between a partial bending from the extensionshown in Figure 1, and a maximum bending in which distance Ll reaches value L2.
The rotation of shaft 10, consecutive to the supply of motor 1, moves slide guide 12 angularly in the direction of arrow fl without initially causing the centripetal movement of slide-block 13. This is permitted by the profile of the cam 29 designed to authorize an angular movement equal to range ~(Figure 1 corresponding to the first natural urging on the MP
articulations. Indeed, during this displacement, the small bar carries the end of the net which then urges the fingers to bend.
As soon as the angular movement of the slide-guide 12 causes the cooperation of the wire or ~3~
.
cable 28 with the profile 30 of the cam 29, slide-block 13 is urged to move in a centripetal direction according to the law corresponding to profile 30. Thus, the bar 21 is caused to follow the curve LX and to control, via the textile sleeve 34, both the bending of MP articula-tions.and, progressively and successively, the bending of the PI and DI articulations of the different fingers.
As illustrated in Figure 1, the means according to the invention thus enable to urge and mobilize the longer fingers in a bending movement which is a start towards the natural clenching movement, thus working, in particularly helpful physiological conditions, all the articulations needing re-education.
In certain cases, the joining means 33 between the small bar 21 and the fingers of the hand, may use (see Figure 7) an adjustable ring 36 for each finger. Each ring 36 is slidably threaded over a flexible plate 37 which extends from a head member 38 made of an~
suitable material. Said head member 38 comprises a bore 39 of orthogonal dire~tion to said plate 37 through which bore is engaged the small bar 210 Said means 33 enable to urge more efficiently any one of the longer fingers or all of them, by providing a possibility of bringing them closer to gether during the bending phase and, in reverse, to move them apart during the stretching phase, thus taking into account the anatomical diverging characteristic of the different fingers of the hand when the hand is open.
Said means 33 also permit to work the PI or DI articulations more intensively, by adjusting the cradle 7 in such a way that the hand rests on the rod 31 not as described hereinabo~e for the MP articula-tions, but for example, by resting the first phalanges on said rod. In such a case, the part 20 is also adjusted ~3~ 34 on the slide-block 13, so as to adapt the small bar 21 in relation to the length of the fingexs to be moved, and thus to cause/ during the curving movement according to curve LX, the bending of the PI and DI articulations only.
When the angular bending range is reached, the reversing contactor 8a, reverses the supply to motor 1 which controls the angular movement of the slide-guide 12 in the opposite direction to arrow f Small bar 21 is caused to move in reverse along the curve LX and in doing so controls the progressive stretching of the worked articulations as a function either of the means 33 used, or of the support adjustments carried out.
It is conceivable that the mobilization of the articulated segments of the thumb can be conducted in the same way, using the net 34 and the clamp 35 or else the ring 36(Figure 8).
If the mobility-restoring apparatus according to the invention is principallv designed to enable simultaneous or individual mobilization of the fingers following the physiological bending characteris-tic thereof through the bending phase, it should be considered that the means used also permit to ~ork a hand to be re-educated, for example, in hyper-stretch-ing conditions.
Indeed, with the means 33 of Figure 6or 7, it is possible to the supply motor 1 for controlling, via the reversing-contactors 8a and 8b, a rotation of the shaft 10 from the neutral position as shown in Figure 2, along the direction of arrow f2 (Figure 1).
It is also possible to use the apparatus for restoring mobility to the wrist which is also consid-ered as an articulation of the hand. In this case, the cradle 7 is adjusted in such a way as to cause the wrist ,.

.
to rest on rod 31, and bending or stretching, after adjusting the position of rod 21, is achieved by providing said rod with a second bar 21a, as shown in Figure 6. Said second bar 21_ is preferably ad-justably movable away from the bar 21. The patient's hand is engaged between bars 21 and 21a adjusted in position by means of piece 20, to be preferably placed substantially away from the MP articulations of the different fingers (Figure 9) According to this particular embodiment, it is generally preferred to disconnect one end of the wire or cable 28, so that the angular movement of slide-guide 12 does not entail the centripetal movement of slide-block 13.
Figure 5 shows that it is possible to produce the cam 29 so that it has a symmetrical profile with respect to an axis P-P` traversing the shaft 10.
Thus by providing two cables or wires 28 extending laterally of the two sides of slide-guide 12, it becomes possible to place the latter either in the position illustrated in Figures 2 and 5, or in a turned over position by assembly on shaft lOa, to adapt the apparatus for re-education of the left hand. In such a case, cam 29 is moved, or preferably, the structure or housing comprises a second cam working with shaft 10_ .
Figure 10 illustrates a development wherein the drive member is constituted by an oscillating lever 40 with multiple arm elements 41, for example four, angularly equidistant. Said arm elements 41 carry balance weights 42 of adjustable position, so as to be able to create a drive torque imparted to the shaft 10 from a stable balancing position.
In such a case, the apparatus permits to keep up a passive mobilization during the oscillating ~L3~
lever moving phase, thus causing an active mobilization helped or opposed by compelling the patient to cause the return of the oscillating lever 40 in its stable position by bending or stretching the fingers.
In the illustrated example of utiliza-tion in Figures 2 to 5, the driving member is fitted inside a housing 2 carried by a structure 3 of the fixed and non-portable type.
In certain cases, it may be advantageous to produce the apparatus so that it is portable, in order to help the mobili~ation/re-education phase con-ducted the patient. Figure 11 shows that it is possible to move the motor inside a bow 2a which can be adapted to support the forearm of the patient. Said box 2a comprises an intermediate arm which is driven by a remote-control transmission means from the shaft 10 or lOa of the motor. In such a case, arm 43 also supports the cam 29 as well as the resting support 31. Inter-mediate shaft 44 carries the slide-guide 12 as indicated hereinabove.
The invention is in no way limited to the description given hereinabove and on the contrary covers any modification that can be brought thereto without departing from its scope.

The present invention relates to the re-education of free articulation of the articulated segments of the hand, namely in particular, the metacarpophalangeal articula-tions, and the proximal and distal interphalangeal articulations, not excluding however the wrist articulation in general, considered according to the invention, as forming also part of the hand.
The recovery of the freedom of articu-lation and of angular amplitude of the articulated segments of the hand, after fractures or surgical interventions is, as we know, essentially dependent on the possibility of restoring the mobility of the affected articulated segments. Such a re-education has always necessitated the services of a specialist, such as a kinototherapist, mainly because of the special ana-tomical nature of the hand.
The prior technique has, up to now,offered no really satisfactory apparatus capable of replacing the manual intervention and capable of adjustably training the articulated segments to move, whilst taking into account the anatomical and physiological nature of the hand.
It is precisely an object of an aspect of the invention to fill this gap by proposing an appa-ratus for re-educating by restoring mobility, which is par-ticularly adapted to the anatomical characteristics of the articulated segments of the hand. The object of the invention is designed so as to be automatically adjustable and adaptable for training one or more articulated segments without the intervention of a practitioner.
The invention proposes to this effect an apparatus which, by its design and adaptability, permits a phase of post-operative training, if only a passive one, to at least some of the articulated segments of the hand, without any risk of any violent and traumatizing strain.

Referring first to Figure 1, this shows a hand in a stretched state in which the different fingers and the palm extend inside a plan Z-2'. In this state, , ~L3~7~9~
the di~ferent parts of the skeleton of the hand, namely the metacarpals, phalanges, middle phalan~ and distal phalanx, are aligned inside said plane Z-Z'. It may also be considered, in this particular state, -that the articulations of the longer fingers, namely the meta-carpophalangeal(MP) articulat:ions, the proximal inter-phalangeal (PI) articulations and the distal inter-phalangeal (DI) articulations, are also aligned inside the same plane. For every longer finyer, the total length L
represents the distance separating an MP articulation from the point PX corresponding to the end of the considered finger.
The bending control of the fingers, in the direction of arrow fl, results first in an urging of the MP articulations, then, progressively and dependlng on the angular amplitude which is reached, by an urging of the IP articulations and finally, by an urging o the ID articulations.
Thus, as the bending movement progresses in the direction of arrow fl, the distance separating, for every finger, the MP articulation from the point PX
reduces, taking, for one reference finger, the value L2 in a virtually fully bent state.
It is clear from figure 1 that the successive urging of the different articulations results in a progressive bending represented by a curve LX which somewhat resembles a spiral.
A mobility-restoring and re-education apparatus must therefore take this physiological particul-arity into account in order to be able to move, if only passively, the articulated segments of the hand and of the longer fingers.
The apparatus according to the invention is designed to meet this requirement.
In the first embodiment illustrated in Figures 2 to 5, the mobility-restoring apparatus comprises ~3~8~
a drive member 1, preferably constituted by an electrical motor-reducer group mounted in a support, casing or hous-ing 2 carried by a structure 3. sy way of example, the structure 3 can be constituted by an underframe ~ on which is fixed by way of an adjusting jaw 5, a system 6 of adjustable bars carrying a support cradle 7 for the forearm.
The electric motor 1 is of the type with two directions of rotation and its supply is controlled by a general control switch, not shown in the drawings, as well as by two end-o~-stroke reversing contactors 8a, 8b, adjustable in position. Said contactors 8a-8b are accessible from the outside of casing 2 and can be adjusted correspondingly to one or more dials or scales bearing graduations representing angular amplitudes. The reversing contactors are designed to be actuated by way of a movable member, schematized in 9 in Figure 2, carried by at least one driving shaft 10 of the motor 1.
Figure 3 shows that motor 1 could be selected to comprise two diametrically opposite driving shafts 10 and lOa, thus offering a reversible possibility of adapting the different members constituting the apparatus, such as described hereinafter.
The driving shaft 10 supports, extern-ally to casing 1, a slide-guide 11, wedged at an angle on the driving shaft by any suitable means. Said slide-guide is mounted so as to e~tend in the direction opposite the cradle 7 with respect to shaft 10.
Slide-guide 11, illustrated in more details in Figures 4 and 5, is for example, produced in the form of a bar 12 forming or comprising means 13 of supporting and linearly guiding a slide-block 13, which is movable in centripetal or centrifugal manner, a radial rectilinear direction with respect to shaft 10.
~3~'751~4 Said support and rectilinear guiding means can be of various types. For example, the bar 12 can define an opening 14 which extends in parallel to the longitudinal axis of the rule to cooperate with a complementary counterpart provided on the slide-block. It is also possible Eor the slide-block to be mounted on at least one guide rod 15.
Guide-block 13 is permanently urged in centrifugal movement by a return member 16, preferably an elastic member~ In the illustrated example, the elastic member 16 is constituted by a helical spring working under compression, and mounted concentrically on rod 15. The spring is tensioned between the slide-block 13 and an abutment 17 formed by an extended portion 18 of the bar 12. Said abutment 17 also acts as a support for the rod 15.
The bar 12 comprises, between the abutment 17 and opening 14, a bearing or sleeve 19 for positioning and angular locking on driving shaft 10.
Different technical means can be used to fulfil this function and for example, as illustrated in Figure 5, the sleeve 1~ can comprise two diametrically opposite flat portions, designed to cooperate with cumplementary flat portions provided on the shaft 10.
The slide-block 13 supports a piece 20 carrying a small bar 21 which extends in parallel to shaft 10. Small bar 21 is preferably adjustable in extension, for example by means of a locking screw 22.
The pieoe20 is mounted on slide-block 13 through an opening 23 through which is threaded a pin 24 rising from the slide-block and provided with a tightening member 250 Opening 23 is so provided as to extend in parallel to the axis of opening 14. Longitudinal guiding means are provided between piece 20 and slide-block 13. Such means can be constituted by flanges 26 extending the 3~3~7~8~
piece 20 downwardly to cooperate with the side faces of slide-hlock 13.
Slide-block 13 is also operationally coupled to means 27 designed to cause its centripetal movement on the bar 12, in relation to the angular movement of the slide-guide by the shaft 10, in the direction of arrow fl. The means 27 comprise ,first of all, at least one flexible but non-extendable cable or wire 28. Said cable is fastened between, substantially, the axis of the sleeve 19 and the slide-block 13, in such a way as to be able to extend laterally to the slide-guide 12 and externally thereto. The means 27 further comprise a cam 29 secured on the bearing struc-ture, in such a way that its plane coincides with the plane in which said cable or wire 2B moves, during the angular movement of slide-guide 12. In the illustrated example, the cam 29 is secured on the casing or housing 2.
Said cam 29 has a profile which is such that the winding of the cable imparts a centripetal movement to slide-blo~k 13 according to a law such that the small bar 21 follows a resultant path comparable to curve LX described in reference to Figure 1.
The apparatus according to the invention further comprises a bearing support 31 consti-tuted by a rigid rod secured to the periphery of a ring 32 adapted to be mounted with a possibility of rotation on the end part of shaft 10 which projects from sleeve 19.
Said rod 31 is designed to extend in parallel to shaft 10 and to small bar 21~
The apparatus such as described herein- .i above can be used in many different ways. According to the illustrated example, the relative adaptation of the different elements constituting the apparatus is designed for an appl:ication as a means of re-educating or mobiliz-ing segments of the right hand.
~3~7913~
The cradle 7 is adjusted in positionso that the forearm of the patient can rest thereon and that the hand can rest by the palm on bearing support 31 placed approximately plumb with the different ~P artic-ulations of the longer fingers. Piece 20 is so adjustedon slide-block 13 as to bring small bar 21 substantially close to the point PX of the longest finger in stretched position.
The use of the apparatus then calls on joining means between sma:Ll bar 21 and for example, the assembly of longer fingers to be moved. Figure 6 shows that such means, designated as a whole by reference 33, can comprise a net 34 shaped as a sleeve through which the longer fingers are introduced. The free end of said sleeve 34, which extends beyond the fingers, is folded over the small bar 21 and held thereon by a clip member 35.
The contactors 8a and 8b are then adjusted so as to determine the angular movement amplitude to be given to the slide-guide 12. Such an ampli-tude may be between a partial bending from the extensionshown in Figure 1, and a maximum bending in which distance Ll reaches value L2.
The rotation of shaft 10, consecutive to the supply of motor 1, moves slide guide 12 angularly in the direction of arrow fl without initially causing the centripetal movement of slide-block 13. This is permitted by the profile of the cam 29 designed to authorize an angular movement equal to range ~(Figure 1 corresponding to the first natural urging on the MP
articulations. Indeed, during this displacement, the small bar carries the end of the net which then urges the fingers to bend.
As soon as the angular movement of the slide-guide 12 causes the cooperation of the wire or ~3~
.
cable 28 with the profile 30 of the cam 29, slide-block 13 is urged to move in a centripetal direction according to the law corresponding to profile 30. Thus, the bar 21 is caused to follow the curve LX and to control, via the textile sleeve 34, both the bending of MP articula-tions.and, progressively and successively, the bending of the PI and DI articulations of the different fingers.
As illustrated in Figure 1, the means according to the invention thus enable to urge and mobilize the longer fingers in a bending movement which is a start towards the natural clenching movement, thus working, in particularly helpful physiological conditions, all the articulations needing re-education.
In certain cases, the joining means 33 between the small bar 21 and the fingers of the hand, may use (see Figure 7) an adjustable ring 36 for each finger. Each ring 36 is slidably threaded over a flexible plate 37 which extends from a head member 38 made of an~
suitable material. Said head member 38 comprises a bore 39 of orthogonal dire~tion to said plate 37 through which bore is engaged the small bar 210 Said means 33 enable to urge more efficiently any one of the longer fingers or all of them, by providing a possibility of bringing them closer to gether during the bending phase and, in reverse, to move them apart during the stretching phase, thus taking into account the anatomical diverging characteristic of the different fingers of the hand when the hand is open.
Said means 33 also permit to work the PI or DI articulations more intensively, by adjusting the cradle 7 in such a way that the hand rests on the rod 31 not as described hereinabo~e for the MP articula-tions, but for example, by resting the first phalanges on said rod. In such a case, the part 20 is also adjusted ~3~ 34 on the slide-block 13, so as to adapt the small bar 21 in relation to the length of the fingexs to be moved, and thus to cause/ during the curving movement according to curve LX, the bending of the PI and DI articulations only.
When the angular bending range is reached, the reversing contactor 8a, reverses the supply to motor 1 which controls the angular movement of the slide-guide 12 in the opposite direction to arrow f Small bar 21 is caused to move in reverse along the curve LX and in doing so controls the progressive stretching of the worked articulations as a function either of the means 33 used, or of the support adjustments carried out.
It is conceivable that the mobilization of the articulated segments of the thumb can be conducted in the same way, using the net 34 and the clamp 35 or else the ring 36(Figure 8).
If the mobility-restoring apparatus according to the invention is principallv designed to enable simultaneous or individual mobilization of the fingers following the physiological bending characteris-tic thereof through the bending phase, it should be considered that the means used also permit to ~ork a hand to be re-educated, for example, in hyper-stretch-ing conditions.
Indeed, with the means 33 of Figure 6or 7, it is possible to the supply motor 1 for controlling, via the reversing-contactors 8a and 8b, a rotation of the shaft 10 from the neutral position as shown in Figure 2, along the direction of arrow f2 (Figure 1).
It is also possible to use the apparatus for restoring mobility to the wrist which is also consid-ered as an articulation of the hand. In this case, the cradle 7 is adjusted in such a way as to cause the wrist ,.

.
to rest on rod 31, and bending or stretching, after adjusting the position of rod 21, is achieved by providing said rod with a second bar 21a, as shown in Figure 6. Said second bar 21_ is preferably ad-justably movable away from the bar 21. The patient's hand is engaged between bars 21 and 21a adjusted in position by means of piece 20, to be preferably placed substantially away from the MP articulations of the different fingers (Figure 9) According to this particular embodiment, it is generally preferred to disconnect one end of the wire or cable 28, so that the angular movement of slide-guide 12 does not entail the centripetal movement of slide-block 13.
Figure 5 shows that it is possible to produce the cam 29 so that it has a symmetrical profile with respect to an axis P-P` traversing the shaft 10.
Thus by providing two cables or wires 28 extending laterally of the two sides of slide-guide 12, it becomes possible to place the latter either in the position illustrated in Figures 2 and 5, or in a turned over position by assembly on shaft lOa, to adapt the apparatus for re-education of the left hand. In such a case, cam 29 is moved, or preferably, the structure or housing comprises a second cam working with shaft 10_ .
Figure 10 illustrates a development wherein the drive member is constituted by an oscillating lever 40 with multiple arm elements 41, for example four, angularly equidistant. Said arm elements 41 carry balance weights 42 of adjustable position, so as to be able to create a drive torque imparted to the shaft 10 from a stable balancing position.
In such a case, the apparatus permits to keep up a passive mobilization during the oscillating ~L3~
lever moving phase, thus causing an active mobilization helped or opposed by compelling the patient to cause the return of the oscillating lever 40 in its stable position by bending or stretching the fingers.
In the illustrated example of utiliza-tion in Figures 2 to 5, the driving member is fitted inside a housing 2 carried by a structure 3 of the fixed and non-portable type.
In certain cases, it may be advantageous to produce the apparatus so that it is portable, in order to help the mobili~ation/re-education phase con-ducted the patient. Figure 11 shows that it is possible to move the motor inside a bow 2a which can be adapted to support the forearm of the patient. Said box 2a comprises an intermediate arm which is driven by a remote-control transmission means from the shaft 10 or lOa of the motor. In such a case, arm 43 also supports the cam 29 as well as the resting support 31. Inter-mediate shaft 44 carries the slide-guide 12 as indicated hereinabove.
The invention is in no way limited to the description given hereinabove and on the contrary covers any modification that can be brought thereto without departing from its scope.
