This application claims priority of Polish Patent Application No.: P.431381, filed on Oct. 4, 2019. The contents of Polish Patent Application P.431381 is hereby incorporated by reference.
This disclosure relates to a device for spine rehabilitation, particularly for patients with painful postural asymmetry, discopathy and degenerative illnesses and a method for spine rehabilitation using said device for spine rehabilitation.
From the description of Polish utility model No PL 60060 there is known a derotational-corrective-redressive device for treating scoliosis, used for active exercise, which is constructed from two frames, frontal and rear, connected at their upper part by guides on which slides are put on. In the lower part of the frontal frame there is mounted a support for hands to which a head hoist is attached and, above, on the rear frame, there is a knee support mounted to which a hip hoist is attached. Two connecting members stabilize the whole device. While exercising on the device a patient, in a supported kneeling position, is stabilized by shoulder blockades and a hip blockade. The patient while performing an exercise called “cat-cow pose” has his/her rib prominence and lumbar bump blocked at their apex by projections in pads which, during the exercise, press against the spine along the curve of the circular sector causing derotation, correction and redression of twisted arches of the spine that is deformed in those places. The other solution that has been disclosed in Polish invention No PL 176238 relates to a scoliosis correcting adjuster which comprises a rectangular base with vertical protrusions on one side of the longer flanks on which a crossbar is retractably mounted whose lift is adjustable along the line perpendicular to the base and along a line running at an acute angle to the base, whereas to the other side of the base there is a blocking plate mounted slidingly and dismountably to its longer flank. To a shorter flank of the base on the opposite side of the vertical protrusions an elastic line is attached which traverses through cut-outs in the longer flanks of the base and which has handles attached to its ends. Moreover, the base is equipped with a belt placed slidingly in cut-outs made in the bottom of the longer flanks of the base.
From Polish patent PL 209439B1 description there is known a device comprising four separate supports supporting a patient—in a substantially horizontal position—his/her head, back in the points of shoulder girdle and pelvis girdle, and calves. These supports are mounted on a frame bearer by ball units which can swing in relation to the long axis of the spine and move vertically and be locked in a chosen position. Angle and level settings of each support introduces required shifts of the vertebra diagonally within anatomical range of the movement. Also, from Polish patent PL 226008B1 there is known a device for stimulation of muscles and rehabilitation of backbone, particularly for patients with painful postural asymmetry, discopathy and degenerative illnesses. The essence of the invention consists in that each sling hanger at its end is connected to linear actuators which are suspended in pairs from the horizontal support frame in the position perpendicular to the axis of the spine, and the movement of each of the linear actuators is individually controlled by the computerized medical control system software. And European application EP 2311424A1 discloses a device for physiotherapy and rehabilitation having a robust supporting structure in the form of a horizontal frame propped at its corners, having four cross elements out of which two middle are slidingly mounted on longitudinal rods of the frame and whose position can be adjusted. Suspended on internal rods there is a longitudinal member which can be pivoted horizontally. Cross-rods slidingly attached to the longitudinal member have on them mechanisms for fitting and adjusting length of slide lines on which the patient's body is suspended. Thanks to additional horizontal lines attached to the sling hanger it is possible to exert force acting along the axis of the spine.
From publication WO 2007/017282A2 there is known an exercise apparatus having, in one of the embodiments of its frame design, a rod structure. The frame is suspended on the ceiling in a way that it can be rotated horizontally and vertically thanks to the use of a ball-and-socket joint and also lifted and lowered thanks to the use of a telescopic member. The frame has a longitudinal supporting member in the form of double rods or tubes. This member also acts as a guide for linear carriages with linear bearings that can move along it. Cross-rods fitted to the carriages have on their ends elements in the form of blocks or eyelets whose position on the rods can be adjusted and locked and which are designed for placing sling hangers on which patient's body is suspended above a bed. Moving parts can be power-driven, for example by an electric motor.
Moreover, from Polish patent description No PL 217824 there is known a device for scoliosis treatment having a main frame in the shape of a cuboid with legs. Upper arms of the frame are connected with an upper beam to which an upper rod is attached by a ball-and-socket joint. Lower arms of the main frame are connected by a lower beam to which a lower rod is attached by a ball-and-socket joint. The upper rod has hand grips and the lower rod has platforms for feet of a person performing exercise. There are upper tightening members attached at the ends of the upper rod, and lower tightening members attached to the lower rod.
The object of the invention is to develop a device allowing to introduce a movement of lateral deviation of the patient's torso during his/her rehabilitation in suspension and a method for carrying out spine rehabilitation using said device.
A device for spine rehabilitation with the use of a method for lateral deviation of the patient's torso comprising a support frame, immovable crossbars, movable crossbars and a holder and actuator assemblies supporting the head, the arms, the hips, the knees and the feet of the patient characterised in that it is equipped with linear actuators mounted on the holder and to the movable crossbars that support the patient, whereby the holder has a driving mechanism, sliding horizontally, mounted on the immovable crossbar of the holder of the supporting frame and which, on its lower part, is fitted to the immovable crossbar equipped with a rotating mechanism. The holder's upper back surface moves on rolling members installed in the immovable crossbar of the holder. Sling hangers for the head and for the shoulders connected on their ends with two linear actuators are suspended in pairs on the movable holder. Moreover, the movement of each of the actuators is controlled individually from a control unit assisted by a computer with medical software. Preferably, the linear actuators in pairs for each of the sling hangers are connected with the holder by slidable assemblies in the direction longitudinal to the axis of the holder and thus allow to adjust positions of the actuators of the sling hanger for the head according to anthropometric size of a particular patient.
A method for spine rehabilitation using the device for lateral deviation of the torso of the patient suspended on the actuators takes place in the device where the patient's body is situated in substantially horizontal position, face up, and is lifted by four sling hangers that take hold of the patient's head, back in the points of shoulder girdle and pelvis girdle, and calves and each of the slings is connected on its ends with two linear actuators suspended in pairs on the horizontal support frame in the position perpendicular do the axis of the patient's spine, whereby the movements of each of the linear actuators is individually controlled from the control system, characterised in that the head and the shoulders of the suspended patient are supported by the actuators fitted in the holder whose transversal movement is provided by the rotating mechanism, whereas a slidable mechanism moves along an arc within a designated range in such a way that the holder's upper surface moves with a swinging motion on the rolling members fitted in the crossbar of the supporting frame, whereas movements of the actuators connected to the surface of the holder cause lateral deviation of the torso and the spine at a designated angle with the possibility of selecting proper frequency and amplitude of the deviations.
The solution presented allows to carry out spine rehabilitation therapy in suspension with a dynamic lateral deviation of the torso optimally selected to a particular affection, with discretionarily varied, medically developed kinematics. The movements of the pairs of the actuators connected to the surface of the holder produces lateral deviation of the torso and of the spine up to a specified deviation angle with the possibility of selecting an adequate frequency and amplitude of the relocation, and, additionally, with various options of the longitudinal interaction of neighbouring sling hangers. For example, with the sling hanger for the pelvis girdle locked, side bending is induced by activating the shoulder girdle sling hanger. This kind of rehabilitation therapy, thanks to this solution, becomes safe and less burdensome while keeping the patient in safety and comfort. The exemplary embodiment of the invention is shown on the accompanying diagrammatic drawings.

In the corners of the frame 1 (
The head and the shoulders of the suspended patient (fig.1) are supported by the linear actuators 8 mounted to the holder 7 whose transversal movement is provided by the holder's driving mechanism 9 along an arc within a designated range of the movement. The holder's 7 upper back surface moves with a swinging motion on the rolling members 11 installed in the immovable crossbar 2 of the support frame 1. Repositioning of the holder's drive (for example an actuator) which connects the holder 7 and the immovable crossbar 6 causes lateral deviation of the torso and the spine to a designated angle with the possibility for selecting an adequate frequency and amplitude of the relocation as set in the control system 17.
The device allows for a precise, three-plane correction of scoliosis. Thanks to the lateral deflection of the spine with the patient in horizontal position on the movable base and also thanks to the three-plane stabilization of the hip in the transverse plane and in the sagittal plane a correction of the spine takes place.
Thanks to its design the device according to the invention allows for spinal correction in three planes and makes it possible to treat in a correct manner scoliosis, rheumatic and neurological diseases. Scoliosis that are improperly treated might lead to a reduced physical capacity of the patient, increased intensity of neurological disorders, permanent disability, and in extreme cases to heart or/and respiratory failure and premature death.
The device according to the invention might be useful to improve efficiency of spine rehabilitation therapy, might be used in rehabilitation centres, in companies producing medical equipment as well as in hospital rehabilitation wards. It is targeted for physiotherapists in order to improve and create new possibilities of working with the patient substantially decreasing energy expenditures in the process of patient rehabilitation.
