Definitions
- the present invention relates to a new device that may be employed in the medical, physical training and/or rehabilitation field and, more particularly, the invention refers to a new apparatus for rehabilitation and/or re-education of an impaired patient, preferably an individual or patient with dysfunction in the lower limbs, to induce walking movements, develop balance and train muscles, preferably in handicapped persons with gross motor impairments, wherein the apparatus is effective in helping correct the postural (stance) structure and also attaining the exact reproduction of human walking, efficiently inducing the movement of the joints of the foot, heel, ankle, knee and hips, all of them with high participation in the walking movements.
- stance postural
- the disabilities that affect the lower limbs basically hinder or limit displacement and the two-legged stance.
- the technical solutions available to persons with motor dysfunctions, for walking rehabilitation purposes can be generally classified in mobile and fixed devices that have been aimed at helping patients recover their walking capabilities, without, however, efficiently achieving the right motor coordination, balance control of the limbs and torso, correction of the body posture and strengthening of the atrophic limbs.
- the known mobile equipment uses the patient's own force to move, using devices commonly known as walkers.
- the systems are based mainly on the force that the patient must exert with the upper limbs on the device that serves as a support to maintain the two-legged stance.
- the devices are a kind of a support or cart moving over some sort of rollers or wheels and the patient must exert the necessary force against the floor to move. It is obvious that the patient must be capable of standing up and walk, at least slightly and this is not possible for patients having strong neurological disorders with practically no muscles in conditions to support the body weight or to move the legs to get a minimal walking distance.
- the above systems do not provide any type of step regulation or limb movement sequence.
- DE 102005014204 to Steinert Chistoph entitled “Old person's natural heading movement stimulator produces movement of lower extremity/limb in frequency and with dynamics of walking, where movements of ankle joint is effected in frequency of heading movement”
- FR 2691127 to of Michel Sarciron entitled “Medical re-training aid to assist patient in controlling feet” disclose devices to primarily stimulate joints and, in particular, ankles.
- US Patent 6,666,798 to Borsheim discloses an apparatus for rehabilitation of a functionally impaired leg of a patient suffering from paralysis, adapted for receiving also an attendant, both, patient and attendant exercising on a treadmill, with the apparatus comprising leg brackets adjacent to the patient's and attendant's knees, a connecting member coupling the leg brackets to transmit motion from an attendant's leg to a patient's leg.
- the apparatus also including an ankle appliance having an upper extension and a lower extension proximate the ankle is attached to a patient's foot and an ankle brace is similarly attached to an attendant's foot.
- the coordinated leg and ankle movement allows a patient's paralysis damaged leg to duplicate the walking motion of an attendant's leg.
- the apparatus also uses handrails in the treadmill and a suspension strap to keep the patient in a suspended position to allow leg movement without the hindrance of up to full body weight.
- This apparatus does not teach neither suggests the possibility of varying the height of the strap to permit the body weight of the patient to be transmitted to the legs to better train the lower limbs supporting at least part of the natural body weight.
- the belt of the treadmill runs always in the same direction without guiding the patient's feet to emulate the entire walking movement, namely along a closed loop.
- the apparatus comprises a harness for supporting the patient, with the patient having their feet affixed to a couple of walking bars to really reproduce the movements of the lower limbs when walking, with the harness being pending from an upper part of the apparatus including height regulating means for moving the harness up and down to have the patient's body weight unloaded on the legs reduced or increased for better training of the legs.
- the apparatus comprises a support structure such as a chassis 2 of a light and resistant construction and material, of aluminium or steel for example, having a base 3, a top or upper end 4 and a plurality of columns 5, 6, 7, 8.
- the chassis 2 is resistant and capable of supporting at least the weight of a patient and the components.
- Walking bars 9, 10 are provided, with the walking bars 9, 10 being mounted to move along a path emulating, duplicating or copying the natural walking movement, such as up and down and back and forth along a closed movement loop, such as a seesaw movement, for example.
- Walking bars 9, 10 may be made of any suitable material such as steel or aluminium and preferably of a hollow metal profile to be resistant and of a light weight to support the patient's weight. The weight of the patient will be controllably unloaded, partially or totally, on the walking bars 9, 10.
- each walking bar 9, 10 has a respective rear end 11, 12 connected to motor means 13 and a respective front end 14, 15 slidably connected to respective front guide means 16, 17.

Abstract
Description
- The present invention relates to a new device that may be employed in the medical, physical training and/or rehabilitation field and, more particularly, the invention refers to a new apparatus for rehabilitation and/or re-education of an impaired patient, preferably an individual or patient with dysfunction in the lower limbs, to induce walking movements, develop balance and train muscles, preferably in handicapped persons with gross motor impairments, wherein the apparatus is effective in helping correct the postural (stance) structure and also attaining the exact reproduction of human walking, efficiently inducing the movement of the joints of the foot, heel, ankle, knee and hips, all of them with high participation in the walking movements.
- For several reasons, an important part of a community is affected by motor disorders or dysfunctions, due to accidental events or to neurological disorders. In any event, in modern communities more and more efforts are being made to incorporate disabled persons to the normal life of the community. The idea is to adopt more effective techniques in order that they may enjoy, depending on the degree of the disability, the autonomy to move among the other members of the community. It is a fact that the degree of dependence affects directly the standard of living of these citizens and, therefore, it is imperative to be socially sensitive to bring to the disabled persons the most modern solutions to cause them to be capable of joining, as long as possible, the normal persons.
- The disabilities that affect the lower limbs basically hinder or limit displacement and the two-legged stance. On top of the difficulty or impossibility of walking, there is the loss of reflexes and muscle tone due to inactivity or reduced functionality, the slowdown of systemic functions such as circulation, the contraction of the abdominal cavity that hampers the respiratory and digestive functions and the proper evacuation of the bowels, progressive scoliosis, bone density loss, as well as diverse dermatological pathologies, all effects that aggravate even more the condition and quality of life of the patient.
- The technical solutions available to persons with motor dysfunctions, for walking rehabilitation purposes, can be generally classified in mobile and fixed devices that have been aimed at helping patients recover their walking capabilities, without, however, efficiently achieving the right motor coordination, balance control of the limbs and torso, correction of the body posture and strengthening of the atrophic limbs. In general terms, the known mobile equipment uses the patient's own force to move, using devices commonly known as walkers.
- One of such mobile devices is disclosed in Document
WO 2008058534, to Sorensen Nicolai and Balle Rune , entitled "Walking device for assisting handicapped persons or patients during rehabilitation". Other apparatus of this type are disclosed inDE 10318929 to Graf Birgit , entitled "Motorised walking aid for assisting disabled person with integrated data detection device for detecting movement data during use of walking aid",EP 0713692 to Paas Dieter , entitled "Walking training device for disabled people". - While the above devices may be helpful in assisting a handicapped person to walk and stimulate walking movements, the systems are based mainly on the force that the patient must exert with the upper limbs on the device that serves as a support to maintain the two-legged stance. The devices are a kind of a support or cart moving over some sort of rollers or wheels and the patient must exert the necessary force against the floor to move. It is obvious that the patient must be capable of standing up and walk, at least slightly and this is not possible for patients having strong neurological disorders with practically no muscles in conditions to support the body weight or to move the legs to get a minimal walking distance. In addition, the above systems do not provide any type of step regulation or limb movement sequence. But what is an additional limiting factor in this type of equipment is that not a single one of them provides for correction of the walking gait; they do not develop adequate motor coordination, and they do not allow for adopting the correct postural stance needed for human beings to take steps in the correct sequence to achieve full rehabilitation.
- Other devices are disclosed in
RU 2306129 to Aliev Gazi Aligadzhievich et al. DE 102005051674 to Miehlich Dieter , entitled "Pulling apparatus for use in e.g. rehabilitation device, for muscle exercise (...) to arms or legs, where power is transmitted to output of motor", andDE 10258755 to of Haas Siegliende, Bayersdorfer Valentin and Hass Hannes , entitled "Walking exercise simulator with shallow inverted V-profile supported each side by springs and motion dampeners". These devices provide the patient with the means to strengthen, exercise and avoid numbness, loss of reflexes and mobility of some of the joints, with which a limited rehabilitation is attained. However, while a movement may be promoted, not all the foot, leg and hip articulations are involved and no achievement of postural fitness, motion balance and good alignment of limbs and torso, which is to be desired of any rehabilitation process are provided. - In addition to the foregoing,
DE 102005014204 to Steinert Chistoph , entitled "Old person's natural heading movement stimulator produces movement of lower extremity/limb in frequency and with dynamics of walking, where movements of ankle joint is effected in frequency of heading movement", andFR 2691127 to of Michel Sarciron -
US Patent 6,666,798 to Borsheim , discloses an apparatus for rehabilitation of a functionally impaired leg of a patient suffering from paralysis, adapted for receiving also an attendant, both, patient and attendant exercising on a treadmill, with the apparatus comprising leg brackets adjacent to the patient's and attendant's knees, a connecting member coupling the leg brackets to transmit motion from an attendant's leg to a patient's leg. The apparatus also including an ankle appliance having an upper extension and a lower extension proximate the ankle is attached to a patient's foot and an ankle brace is similarly attached to an attendant's foot. Thus, the coordinated leg and ankle movement allows a patient's paralysis damaged leg to duplicate the walking motion of an attendant's leg. The apparatus also uses handrails in the treadmill and a suspension strap to keep the patient in a suspended position to allow leg movement without the hindrance of up to full body weight. This apparatus does not teach neither suggests the possibility of varying the height of the strap to permit the body weight of the patient to be transmitted to the legs to better train the lower limbs supporting at least part of the natural body weight. In addition, the belt of the treadmill runs always in the same direction without guiding the patient's feet to emulate the entire walking movement, namely along a closed loop. - As it can be seen, the state of the art and existing technologies do not offer those individuals suffering from severe motor dysfunctions an integral solution for their rehabilitation, obtaining only partial results. There is no fixed or mobile device that enables these people to rehabilitate, achieve postural fitness, motion balance and good alignment of limbs and torso, with the advantage of strengthening and working out the muscle system, tendons and circulatory system, as well as all the joints involved in the walking activity, supporting the patient's body weight in an adjustable pattern, all in a single device.
- It is therefore an object of the invention to provide an apparatus for rehabilitation of patients with motor disorders, wherein the apparatus comprises an harness for supporting the patient and a couple of walking bars to which the feet of the patients are affixed to, and wherein the device helps rehabilitate the lower limbs of people with severe motor disorders, making it possible to increase muscle tone and helping the individual to develop balance, whereby patients suffering from central nervous system disorders manage to improve their muscular activity and to normalize their muscle tension.
- It is still another object of the present invention to provide an apparatus for rehabilitation of patients with motor disorders, wherein the apparatus comprises a harness for supporting the patient, with the patient having their feet affixed to a couple of walking bars to really reproduce the movements of the lower limbs when walking, step by step at a constant pace, stimulating the nervous system with a mechanical movement generated from the lower limbs themselves, wherein, by systematically and repeatedly practising the exercise produced by the device, the patient, by reflex and voluntary activation, executes the movements necessary to help him/her walk and/or rehabilitate thanks to the recovery of the normal tone of his/her muscles.
- It is even another object of the present invention to provide an apparatus for rehabilitation of patients with motor disorders, wherein the apparatus comprises a harness for supporting the patient, with the patient having their feet affixed to a couple of walking bars to really reproduce the movements of the lower limbs when walking, with the harness being pending from an upper part of the apparatus including height regulating means for moving the harness up and down to have the patient's body weight unloaded on the legs reduced or increased for better training of the legs.
- It is a further object of the present invention to provide an apparatus for rehabilitation of patients with motor disorders affecting the legs, the apparatus comprising a couple of bars moving along a closed loop representing a walking step for the patient, with each bar including a plate to affix a foot of the patient and the plate being slidably arranged in the bar, with a motor connected to the bars to move the bars along the closed loop, the apparatus also having an harness to support the patient.

Thus, atransverse roller 64, seeFigure 6 , is connected to armlengths 62 ofextensible arms bar 9 and aspring Figures 5 ,10 , is connected to eachextensible arm arm length 62.Springs guide stop plate 56 under a resilient force urged against walkingbar 9 andtransverse roller 64 keeps frontguide stop plate 56 in position relative to walkingbar 9 to guarantee that frontcurved edge 48, seeFigure 10 , will always move onto frontguide stop plate 56 when reaching theplate 56 in the forth movement of the walkingbar 9. - As to the movement of the patient's feet at the rear part of the walking movement, reference will be made to the rear guide stops 54, 55, however, for clarity purposes only rear guide stop 54 for the left foot will be described in detail as long as the rear guide stop 55 for the right side is identical. Rear guide stop 54 comprises two curved rear U-shaped guides, indicated by
general references horizontal guide lengths guide lengths Figure 8 ,13 . Associated withrear guides plate 44 is provided with guide follower ends, such as rollers at the end thereof, which rollers run into theupward guide lengths Figures 12 ,13 illustrating the left foot in that position. Since the guide follower ends, namely the rollers, ofplate 44 do not appear in the drawings, reference is made to the rollers ofplate 45, identical to the rollers ofplate 44, with one of which being shown inFigures 8 ,13 and indicated byreference 73. - To follow the walking movement of the walking
bar 8,rear guide stop 54 is provided with arear carriage 74 firmly affixed, by welding for example, torear guide stop 54 and includingupper rollers lower roller 77, at both upper and lower sides of walkingbar 9, to keeprear guide stop 54 and walkingbar 9 together during the movement of the walkingbar 9.

The rear end ofarm length 83 will be pivotally connected tocarriage 74 at a joint 88. - While the leading guide stops 52, 53 and the rear guide stops 54, 55 have been illustrated and disclosed as being different of each other, it is important to remark that the leading and rear guide stops 52-55 may be identical or the
leading guide stop rear guide stop guides rollers 73. Thus, the use of curvedleading edges curved edges upper foot plates - It is clear from the above description that, when the patient's feet are retained at the foot retaining means 35, 36, the feet move together with the walking bars 9, 10 along the closed loop or step distance path, to copy the movement of a walking step. The stroke/run of the step is limited by the length of connecting
rods front guide stop 52, thefront guide stop 52 impels the instep (forefoot) upwards because the frontcurved edge 48, withfoot plate assembly 37 moving forth, enters into contact with the frontguide stop plate 56 which causesupper foot plate 39 to move upwards and pivot aroundhinge 47, seeFigure 9 . In like manner, when the foot reachesrear guide stop 54, rollers ofplate 44, see as areference rollers 73 of the right foot, are guided upwardly alongupward guide length foot plate assembly 37, namelyplates bar 9. Thus, therear guide stop 54 pushes the heel upwards, thus triggering the movement in the symphysis of the foot during walking. To prevent any foot, that may get loose from the foot retaining means 35, 36, from moving to a place between the walking bars 9, 10 and getting trapped under a scissor effect of the walking bars 9, 10 moving up and down, preferably rear guide stops 54, 55 are provided withside panels Figure 8 , defining a protection for the feet. Alternatively, the apparatus 1 is provided with a stationary panel affixed to thechassis 2 and located in the gap between the walking bars 9, 10. - Considering that the patient is not in conditions to keep itself in a stand up position, the apparatus 1 may be provided with patient's supporting means for supporting and keeping the patient in a desired position. These means may comprise parallel bars, if the patient is in conditions to keep his/her body sustained by the arms, or, preferably, may comprise a supporting harness, generally indicated at 89 only in
Figure 14 for clarity purposes, pending from theupper end 4 of the apparatus 1 and/or connected to columns 5-8.Harness 89 may be of any type capable of appropriately sustaining and supporting the patient and placing him in the desired position but preferably, theharness 89 is connected toupper belts 90 to keep the patient sustained from the shoulders andtorso belts 91 to be affixed to the patient's torso, from the waist and/or groin and/or hips. - The
harness 89 is connected to harness motor means 92, which may comprise a crank handle, as illustrated or an electric motor capable of moving the harness up and down. Thus, the weight of the patient actuating on the patient's legs will be regulated as desired. According to this embodiment,upper belts 90 are connected to arotating shaft 93, operated by the crank handle, to roll up the belts. A longitudinal and lateral adjustment of the patient position may be carried out by means ofrear torso belts torso belts shaft 93 also may move along guide bars 98, 99, bysupports harness 89 longitudinally. - According to another embodiment of the invention, the apparatus 1, in addition to
chassis 2, has a side chassis orside portion 102 for receiving patients in wheel chairs.Side portion 102 also is comprised ofcolumns entrance 106 for a wheelchair, stretcher and the like. Theupper end 4 of the apparatus 1 has a pair of guide beams 107, 108 and aframe 109 which is capable of moving along the guide beams 107, 108 to be placed in a position to receive a patient, shown inFigure 14 , and a position to support the patient during treatment, shown inFigure 15 . Harness motor means 110, such as an electrical motor, is mounted inframe 109 to actuate arotary shaft 111, to move the harness up and down. Harness motor means 110 androtary shaft 111, move withframe 109 along the guide beams 107, 108 which thus define a motor guide for moving the harness motor means 110 between the above described positions. - In
Figure 16 , an apparatus 1 according to even another embodiment of the invention is shown, wherein all the apparatus 1 components and parts that are common to those ones of the embodiments shown inFigures 1-15 have been indicated by the same reference number. Thus, the apparatus 1, preferably designed to support higher weights in a shorter design, is also comprised of achassis 2 with abase member 23 and with aleft walking bar 9 and aright walking bar 10 with their respective leadingends having rollers foot plate assemblies intermediate walking bar 112 and a rightintermediate walking bar 113, both moving up and down and back and forth along a closed movement loop. - Each
intermediate walking bar rear end Figure 4 or may comprise amotor 117 connected to a speed reducing gear box 118 to move agear box 119 which in turn is connected to connectingrods Connecting rods Connecting rods joints rear ends intermediate bars - The connection between walking
bars connections respective brackets brackets bars intermediate bars rollers Figure 16 , running along and into respective front intermediate guide means, of which only one intermediate guide means 136, for leftintermediate walking bar 112, is shown. - The apparatus of the invention provides a range of services in treating patients suffering motor dysfunctions, neurological disorders, standing disorders and the like that is superlative as compared to other devices of the prior art. The new design and combination of components provides a wider range of movements and adjustments to different patients, also stimulating the standing equilibrium. No rods or complex retaining means are necessary to affix to the legs of the patient but only simple straps for example, are necessary to brace the patient's feet to firmly retain the same in the walking bars.
- Since only the feet are affixed to the walking bars, the feet follow the movement of the walking bars along the closed loop copying the natural walking movement thus causing the feet, with all their joints, to move accordingly. Thus, the movement to the legs is imposed at the feet and not to the entire extension of the legs. As a result, the patient, after some treatment sessions, feels that he/she can move the legs to accompany the feet movement.
- While preferred embodiments of the present invention have been illustrated and described, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention as defined in the appended claims.
