Embodiments of the present invention relates to apparatuses and methods of providing physical rehabilitative therapy for patients including reanimation, physical rehabilitation, and/or treatment of patients, who are either fully immobile or partially immobile. The methods and apparatuses may be employed to treat a wide variety of medical conditions and are suitable for use in specialized medical institutions, at home, or in the field.
More particularly, embodiments of the present invention relates to apparatuses and methods of providing physical rehabilitative therapy for patients including reanimation, physical rehabilitation and treatment of patients, where the apparatuses includes a base subsystem or assembly, an inflatable subsystem or assembly including a plurality of inflatable members, an inflation control subsystem or assembly including a processing unit and a plurality of valves, gas controllers, and a pump or a plurality of pumps under control of the processing unit, and optionally an adjustment subsystem or assembly comprising a plurality of adjustment members that permit the apparatus to be conformed to a patient prior to use and where the inflation control subsystem is capable of controlling an inflation pressure in each inflatable member independently.
Whilst modern methods of intensive care have greatly reduced instances of mortality from traumatic shock deaths and severe illness from subsequent medical decubitus (long term bed bound) complications such as pressure ulcers, contractures, bronchial pneumonia etc. have not decreased to the same degree. Existing world medical practices in combating decubitus complications involves medical devices that vary in both complexity and price. The basic principles that many such devices employ to combat the onset of pressure ulcers are the periodic changing of the support surfaces of the body of the patient and/or pressure distribution to reduce soft tissue ischemia. Such devices, however, while reducing soft tissue ischemia, the devices do little to prevent or counteract other serious decubitus complications such as pneumonia/atelectasis, disuse osteoporosis, impaired digestion and excretion, muscle atrophy, contractures, poorly functioning metabolism, hormonal system and impaired blood and lymph circulation. One such device and methods for using the devices may be found in U.S. Pat. No. 5,586,346.
While other beds for assisting patients have been developed and used in hospitals, homes, and in the field, there is still a need in the art for new and novel bed apparatuses for patients capable of reducing bed sores and muscle atrophy and assisting in patient reanimation, physical rehabilitation, and treatment.
Embodiments of this invention provide apparatuses adapted to change a position of a body, where the apparatuses include: (a) an inflatable subsystem or assembly including a plurality of inflatable members, (b) an inflation control subsystem or assembly including at least one processing unit and a plurality of valves, gas controllers, and a pump or a plurality of pumps under control of the processing unit (c) a base subsystem or assembly including a rigid corrugated plastic base through which air hoses run from the main pump-controller to the multiple parallel inflatable air sacs, and (d) optionally, an adjustment subsystem or assembly comprising one or a plurality of adjustment members. The inflation control subsystem/assembly is adapted to change an inflation pressure in each of the inflatable members allowing the apparatuses to change, alter, and/or redistribute pressure on different parts of a patient's body including an upper spine, legs, right trunk side, left trunk side, arms, neck, head, etc. The apparatuses may also be used to move the body, body parts, and/or body structures into various positions and to move the body, body parts, and/or body structures along various trajectories by changing an air pressure distribution of the inflatable members. The trajectories may include, without limitation, raising and turning the head, raising and turning the chest, turning and lifting the whole back, raising and lifting the lumbar, raising and lifting the pelvis, raising and bending the legs together at the knee or at the hip and raising the legs separately at the knee or the hip in a “bicycle” fashion for accomplishing specific treatments or treatment protocols, changing the air pressure distribution in the inflatable members to accomplish specific treatments or treatment protocols for other body parts, etc. These body movements are accomplished while the patient is situated on the apparatus. In certain embodiments, the apparatuses also include an adjustment subsystem or an adjustment assembly comprising a plurality of adjustment members that permit the apparatus to be conformed to each patient.

Once the patient is lying on the apparatus, air pressure is introduced into the inflatable members and regulated so as to increase and/or decrease pressure on different parts of the body during selected time frames and during patient body positioning actions. The methods may also include the step of moving the body into various trajectories such as raising and turning the head, raising and turning the chest, turning and lifting the whole back, raising and lifting the lumbar, raising and lifting the pelvis, raising and bending the legs together at the knee or at the hip and in one embodiment of the invention raising the legs separately at the knee or the hip in a “bicycle” fashion for accomplishing specific treatment of other parts of the body during times situated on the apparatus by changing air pressure in the inflatable members so that each movement is accomplished.
The invention can be better understood with reference to the following detailed description together with the appended illustrative drawings in which like elements are numbered the same:
Potential Patient Positions

The inflatable subsystem/assembly under the control of the inflation control subsystem/assembly allows the apparatuses of this invention to actively, periodically, intermittently, or randomly reposition bed ridden patients or to reposition a patient on the apparatuses of this invention according to a repositioning, rehabilitative, and therapeutically program, schedule, or protocol.
The inventors have also found that aligning the patient correctly on the apparatus aids in maximizing a beneficial impact of a given treatment program, schedule, or protocol. Thus, the apparatuses may also include an adjustment subsystem or an adjustable assembly comprising a plurality of adjustment members. Once the apparatuses are adjusted to conform to a particular patient, the apparatuses allow for the adjustment of the pressure distribution in the inflatable members of the inflation subsystem/assembly to change the pressure on different sections of the body. By adjusting the pressure distribution according to a program, schedule, or protocol allows a body laying on the bed apparatuses to be moved along various trajectories and in doing so provides a highly rehabilitative effect.
The inventors have also found that the apparatuses and methods provide a wide range of movement exercises and body positioning exercises for the key areas of a patient's muscular-skeletal system by the application of pressure to the body so as to move it in three dimensions and in various combinations.

The movements may include, without limitation, turning the legs and spine, lifting the legs to any angle, turning the legs and spine in different directions, lifting and turning the body at the pelvis, lifting and turning the body at the waist as well as other combinations and to provide a massage effect. The all pneumatic construction of the apparatus and the use of elastic fixings or attachment member to connect its multiple parts allow the apparatus to contour itself to the patient's body form. This conformity to the body structure coupled with the smooth interaction and movement of the pneumatic levers or lever members assists in changing the position of the patient with a wide range of movement and minimizes damage to the soft tissue of the patient through friction and shear.

In certain embodiments, the apparatus may also include an outer shell of elastic material that covers all or a portion of the inflatable assembly. In certain embodiments, the shell cover the entire inflatable assembly and is attached to the apparatus via hook and loop fastening members or fixings disposed on edges of the shell. In other embodiments, the shell covers only the body sacs or the body and the leg sacs again via hook and loop fastening members or fixings disposed on edges of the shell. The parallel inflatable sacs are positioned on top of multi layered pneumatic lever members that are detactably attached to and positional adjustable on a rigid corrugated plastic base through which various flexible plastic air hoses run from a main pump-controller to the inflatable air sacs, pneumatic lever members, and multi-layered longitudinal pneumatic inflatable side lever members. The side lever member may comprise long tubes made of strong hermetic material. The apparatus may also include adjustment members distributed along a length of the side lever members so that the apparatus may be adjusted to accommodate different patient especially at the hip and knee positions.
The apparatuses are designed so that a patient may be moved in three dimensions intermittently, semi-periodically, periodically, or according to a protocol, schedule, or routine. The apparatuses allow patients to be positioned and repositioned in various ways so that the patient may assume different lying and sitting positions. The apparatuses also may be adjusted to turn a patient's legs and twist about a patient's spine, to lift a patient's legs at any angle, to turn a patient's legs and spine in different directions, to lift and turn a patient's body at the pelvis, to lift and turn a patient's body at the waist, to provide a massage effect, and/or to provide an exercise effect.
The fully pneumatic construction of the apparatus and the use of elastic fittings to connect the parallel inflatable sacs with one and other and with the pneumatic lever members and the base allows the apparatus to contour itself to the patient's body form. In certain embodiments, the apparatus also include adjustment members to adjust the apparatus to each patient so that the hips and knees may be moved. The pneumatic lever members combined with the sacs permit smooth interaction and movement to change a position of the patient. These changes allow a wide range of movements to be performed minimizing damage to soft tissue to a patient through friction and shear.
Embodiments of this invention broadly relate to methods of changing a position of a body placed on a bed apparatus of this invention via a redistribution of air pressure in one, some, or all of the inflatable members of the inflation assembly. Such pressure redistributions may be used to change a position of an upper spine, a lower spine, legs, right and left sides of the trunk, neck, head, etc. In certain embodiments, the methods include, prior to a patient being placed on the apparatus, adapting the apparatus to a patient's body proportions using an adjustable assembly including adjustment member. Once the patient is placed on the apparatus, the methods include introducing air pressure into one, some, or all of the inflatable members of the inflation assembly to achieve a desired body configuration or orientation or position. The method also include adjusting and/or regulating a pressure in one, some, or all of the inflatable members so as to increase and decrease pressure on different body parts intermittently, semi-periodically, periodically, according to a schedule, regime, regiment, or protocol. The methods may also include adjusting and/or regulating a pressure in one, some, or all of the inflatable members over a time frame or period to invoke a patient body positioning activity schedule, regime, regiment, or protocol. The methods may also include treating body parts by adjusting and/or regulating a pressure in one, some, or all of the inflatable members to move the body into one or a plurality (one or more) trajectories, where the trajectories include, without limitation, raising and turning the head, raising and turning the chest, turning and lifting the whole back, raising and lifting the lumbar, raising and lifting the pelvis, raising and bending the legs together at the knee or at the hip, etc. The methods may include adjusting and/or regulating a pressure in one, some, or all of the inflatable members to raise and lower the legs separately at the knees and/or the hips to simulate a “bicycle” type action.
The apparatus is straightforward to manufacture and is designed for use in hospitals, nursing centers, rehabilitation centers, at home, or in the field and may be powered by an source of electric power including electricity from the electrical grid (hospitals, centers, homes, etc.), electrical power from generators, or electric power from batteries or any other source of electric power. The apparatuses may be controlled manually through a controller or wirelessly through a computer in communication with the inflation control assembly, where the communication may be over an intranet or an internet using communication hardware and software. The apparatuses may also include software that allows complex movement programs to be formulated, stored, and activated. In certain embodiments, the software may be voice activated and controlled.
Aligning the patient correctly on the apparatus is necessary for the maximal beneficial impact of a given treatment program. The apparatus allows for the introduction of pressure to different regions of the body, which when regulated moves the body into different positions and/or trajectories to provide a rehabilitative effect.
In certain embodiments, the methods of this invention relate to changing a position of a body by applying differential pressure to one or more body regions so as to move the body in three dimensions randomly, intermittently, semi-periodically, periodically, or according to a regiment, regime, protocol or schedule. In particular, the pressure applying step permits the body position to be changed in a lying position, a sitting position, or both. Thus, the methods may change pressure on the body to turn the legs and spine, lift the legs to any angle, turn the legs and spine in different directions, lift and turn the body at the pelvis, lift and turn the body at the waist, or moving the body in a sequence to provide a massage effect. Such patient specific movement combinations may be programmed directly into the processing unit of the apparatus control assembly or via a remote control computer software interface.
In other embodiments, the inflatable subsystem or assembly of the apparatuses of this invention for changing a position of a body comprises a support surface comprising a plurality of parallel inflatable air sacs. The parallel inflatable air sacs are deposed or placed on a plurality of multi-layered inflatable pneumatic levers or lever members. These lever members are attached to longitudinal multi-layered inflatable side pneumatic levers or lever members disposed down lateral edges of the air sacs. The inflatable assembly also includes a plurality of multi-layered inflatable pneumatic envelope levers or lever members. The air sacs and lever members are connected to the inflation control assembly, which regulates an inflation pressure (inflates or deflates) in the sacs and lever members. Certain of the multi-layered pneumatic levers or lever members comprise tubes of a cigar or cylindrical shape. Other lever members include a folding members allowing the member to fold back on itself at a location along its lengths (i.e., a location in their longitudinal direction). The folding member comprises a hook and loop strap encircling the member at the fold location. The member is anchored at one end to the base, to other inflatable members by the folding member and at it other end to other inflatable members. The hook and loop folding member or strap becomes a fulcrum and hinge for the pneumatic lever, which operates through the introduction of air into the lever member causing the member to inflate so that an upper portion (portion above the strap) lifts and arcs upwards about the hook and loop strap hinge point, while the lower portion (portion below the strap) supports the upper portion. When air is pumped out of the lever member, the upper portion folds over the lower portion and arcs back down as a lever arm around the same hook and loop strap hinge point. These levers function to move an upper body of the patient, while other move the legs and lower body of the patient into different positions or along desired trajectories,
The pneumatic levers are made out of a strong hermetic material and may have the same or different size and shape different diameters or widths and/or lengths. The hermetic material layers give the levers (generally tubular) added rigidity and balance. The levers may also includes different inflatable sections that may be inflated and deflated to give added functionality to the levers. In certain embodiments, the lever is constructed to allow the lever to lift the knees of the patient without lifting the whole leg. In other embodiments, the lever member is constructed to lift a desired area of the patient's back without having to lift the whole upper body. In other embodiments, the levers are combined into pairs that are placed at optimal positions below the patient symmetrically on either side of the longitudinal center line.
Other pneumatic levers take the form of two or more inflatable envelopes of different sizes and/or shapes constructed of a strong hermetic material. These envelopes are joined and overlap one another. When all of the envelopes are inflated simultaneously, the lever member raise evenly and lift the body area of the patient under which they are located in an upwards direction. When the envelopes are inflated and deflated in designated and controlled sequences, they may move the body area of the patient under which they are located in different sideways and forward trajectories. Such multi-layered pneumatic levers are used to lift and turn the head and neck, the thoracic spine, the pelvis or other chosen body areas, etc. Again, these pneumatic levers are constructed out ofhermetic material layers giving the levers added rigidity and balance. Certain layers may comprise additional air tubes or sections made of hermetic material that may be inflated and deflated so as to give added functionality to the pneumatic levers.
All of the inflatable members sacs or levers are connected by flexible supply tubes or conduits to the control assembly and proceed from the inflatable member into and through the base to the control assembly that include one or more pumps and valves and controllers so that the pressure in each inflatable member may be controlled. Of course, the control assembly may be configured to control certain members collectively (all receiving the same air pressure), but the control assembly is capable of independently adjusting the pressure in each inflatable member. In this way, the pressure imparted to different portions of a body may be independently controlled to allow a body to be positioned in a number of different positions and/or to allow the body to undergo movement according to a trajectory and/or to allow the body to cycle through different positions or trajectories according to a schedule, regime, regiment, sequence or protocol.
The apparatuses may also include an outer upper covering shell of an elastic material that covers an entire longitudinal and transverse upper region of the apparatuses and which is connected to the parallel inflatable sacs below their upper surface by means of hook and loop attachments or fixings. The parallel inflatable sacs are positioned on top of the multi layered pneumatic levers that are fixed and position adjustable on the rigid corrugated plastic base through which air hoses or conduits run from the control assembly to the parallel inflatable air sacs, pneumatic levers, and multi-layered longitudinal pneumatic inflatable side levers. The longitudinal pneumatic inflatable side levers comprises long tubes made of strong hermetic material that may have their diameter adjusted at points along their lengths so that the apparatuses may be conformed to a patient's hip and knee joints for improved therapeutic movement.
In other embodiments, the apparatuses of this invention includes multiple identical parallel inflatable sacs, multi layered pneumatic levers, multi-layered longitudinal pneumatic inflatable side levers and a base all connected to one symmetrically along a longitudinal center axis by means of elastic hook and loop fixing tape connectors and furthermore the multiple identical and parallel inflatable sacs are arranged and fixed on parallel hook and loop fixing strips. The use of hook and loop fixings on the apparatus allows for easy adjustment, assembly and disassembly.
The fully pneumatic construction of the apparatuses of this invention and the use of elastic fittings to connect the multiple identical inflatable parallel sacs to each other and to all of the levers and the base in cooperation with the adjustment members allows the apparatuses of this invention to be conformed to a patient's body structure. The conformity to a body structure coupled with the smooth interaction and movement of the pneumatic levers assists in changing the position of the patient with a wide range of positions and movements to minimize damage to soft tissue due to friction and shear.
In other embodiments, the apparatuses include multiple identical inflatable parallel sacs that are positioned on the multi-layered pneumatic levers configured to raise and lower legs. In certain embodiments, the sacs are split in a lower half of the apparatus along the longitudinal center line allowing the legs to be raised and lowered independently of one and other to simulate a bicycle action or other independent leg actions.
In other embodiments, the base of the apparatus is also used as a top of a packaging shell that resembles a compact suitcase.
The apparatuses of this invention may be used to position a patient in a positions that would be of medical benefit or may be configured to exposed the patient to a sequence of movements. The movement sequences may be manually entered or may be programmed into the processing unit so that the apparatuses will executed the sequence randomly, intermittently, semi-periodically, periodically, or according to a schedule. Thus, a user may manually adjust the inflation of the inflatable members to raise a patient from a lying position to a sitting position and then through a bicycle type motion of the legs, or the user may program the sequence into the processing unit or transmitted the sequence from a remote computer to the processing unit, and the processing unit would execute the sequence once, randomly, intermittently, semi-periodically, periodically, or according to a defined schedule.
The apparatuses includes an adjustment assembly comprising hook and loop strap that allow one, some or all of the inflatable sacs and levers to be adjusted to conform to a patients body. Thus, prior to pressure being applied to the inflatable members of the apparatus, the adjustment members are adjusted so that the sac and lever members best match (conform to) a patient's body proportions. Once adjusted to a patient, the patient is laid down on the apparatus along its central longitudinal axis. The physical characteristics of each patient are taken into consideration when setting up the apparatus so that pressure is directed to the correct points on the body. Pressure is then applied to various parts of the body such as the spine, left and right side of the torso and the legs in accordance with the patient's set programme of rehabilitation that has been formulated to meet their specific medical requirements.
A method for changing the position of the body and apparatus for its realization involves the redistribution of pressure on the upper spine, legs, right and left sides of the trunk. A new feature in the method is that prior to the patient being laid down on the apparatus surface the apparatus is adapted to the patient's body proportions using its adjustable features. Once the patient is lying on the apparatus air pressure is introduced into it and regulated so as to increase and decrease pressure on different parts of the body during selected timeframes and patient body positioning actions. In addition the apparatus facilitates further treatment of other parts of the body by moving the body into various trajectories such as raising and turning the head, raising and turning the chest, turning and lifting the whole back, raising and lifting the lumbar, raising and lifting the pelvis, raising and bending the legs together at the knee or at the hip and in one embodiment of the invention raising the legs separately at the knee or the hip in a ‘bicycle’ fashion. Aligning the patient correctly on the apparatus is necessary for the maximal beneficial impact of the given treatment programs. The apparatus allows for the introduction of pressure to different sections of the body which when regulated moves the body into different trajectories and in doing so provides a highly rehabilitative effect.
The method as stated above wherein the application of pressure to the body so as to move it in three dimensions and in various combinations, in particular, in both the lying and sitting positions respectively, turning the legs and spine, lifting the legs to any angle, turning the legs and spine in different directions, lifting and turning the body at the pelvis, lifting and turning the body at the waist and providing a massage effect. Such patient specific movement combinations may be programmed directly into the apparatus controller or via its dedicated computer software interface.
The method as stated above further comprising a support surface of a number of parallel inflatable air sacs that are placed on multi-layered inflatable pneumatic levers made out of a strong hermetic material that are of different diameters and different lengths which are attached to longitudinal multi-layered inflatable side pneumatic levers that are all interconnected by flexible air tube connections to multi-layered inflatable pneumatic envelope levers which are all connected to a controlling apparatus to regulate the inflation and deflation of said sacs and multi-layered pneumatic levers. Some of these multi-layered pneumatic levers are made of tubes of a cigar shape or other forms that are created by folding the tubes back on themselves at a chosen point in the longitudinal direction and then affixing hook and loop tape across and inside the fold and then anchoring the hook and loop to the apparatus base and/or an adjoining air tube. This hook and loop fixing then becomes the fulcrum and hinge for the pneumatic lever which operates through the introduction of air into the pneumatic air lever tube the upper folded over section of which then lifts and arcs upwards as a lever arm from and around the hook and loop hinge point. When air is pumped out of the same pneumatic lever the upper folded over section lowers and arcs back down as a lever arm around the same Velcro hinge point. Such pneumatic levers move the entire patient's upper body and legs into different trajectories. These pneumatic levers are multi layered with certain hermetic material layers giving the tubes added rigidity and balance and certain layers comprising additional air tubes made of hermetic material that may be inflated and deflated so as to give added functionality to the pneumatic levers which in one embodiment of the invention allows air levers to lift the knees of the patient without the requirement to lift the whole leg and in another embodiment of the invention to lift a chosen area of the patient's back without having to lift the whole of the patient's upper body. Such pneumatic levers are combined into sections of pairs that are placed at the optimal position below the patient symmetrically at either side of the longitudinal centre line. Other pneumatic levers take the form of two or more inflatable envelopes of different sizes and of various shapes and made of strong hermetic material. These envelopes are joined and overlap one and other and when they both or are all inflated simultaneously they raise evenly and lift the body area of the patient under which they are located in an upwards direction. When these envelopes are inflated and deflated in designated and controlled sequences they may also move the body area of the patient under which they are located in different sideways and forward trajectories. Such multi-layered pneumatic levers are used to lift and turn the head and neck, the thoracic spine, the pelvis or other chosen body areas. These pneumatic levers are multi layered with certain hermetic material layers giving the tubes added rigidity and balance and certain layers comprising additional air tubes made of hermetic material that may be inflated and deflated so as to give added functionality to the pneumatic levers.
The method as stated above wherein the apparatus has an outer upper covering shell of elasticated material that covers the entire longitudinal and transverse upper area of the apparatus and which is connected to the parallel inflatable support surface sacs below it by means of Velcro fixings. These parallel inflatable sacs are positioned on top of the multi layered pneumatic levers that are fixed and position adjustable on a rigid corrugated plastic base through which the various flexible plastic air hoses run from the main pump-controller to the multiple parallel inflatable air sacs, pneumatic levers and multi-layered longitudinal pneumatic inflatable side levers which are in the form of long tubes made of strong hermetic material that can have their diameter adjusted at required points so as to fit to the patient's requirements such a the hip and knee joints position.
The method as stated above wherein the abovementioned means also facilitates the movement of the patient's body in three dimensions and in various combinations, in particular, in both the lying and sitting positions respectively, turning the legs and spine, lifting the legs to any angle, turning the legs and spine in different directions, lifting and turning the body at the pelvis, lifting and turning the body at the waist and providing a massage effect.

The use of such Velcro fixings on the apparatus allows for its easy assembly and disassembly.
The method as stated above wherein fully pneumatic construction of the apparatus and the use of elastic fittings to connect the multiple identical inflatable parallel inflatable sacs with one and other and with all the pneumatic levers and the base allows the apparatus to contour itself to the patient's body form and combined with the smooth interaction and movement of the pneumatic levers assists in changing the position of the patient with a wide range of movement and minimises damage to the soft tissue of the patient through friction and shear.
The method as stated above wherein the multiple identical inflatable parallel inflatable sacs which are positioned on the multi-layered pneumatic levers for raising and lowering the legs are split in the lower half of the apparatus down the longitudinal centre line allowing the legs to be raised and lowered independently of one and other in a bicycle fashion.
The method as stated above wherein the odd and even flexible air hoses from the multiple identical parallel inflatable sacs are connected with the multi-layered longitudinal pneumatic inflatable side levers.
The method as stated above wherein the corrugated plastic material that forms the base of the apparatus is also used as a packing material of the apparatus so that when packed it resembles a compact suitcase.

In order for the patient be moved comfortably from a lying to a sitting position or from side to side, the apparatus 100 is equipped with the longitudinal multi-layered inflatable side support levers 10 that are connected to the sacs 8 and 9 (if present) via hook and loop fixing members. These longitudinal inflatable multi-layered side support levers 10 include the cuffs 12 and 13 formed with hook and loop tape strips and adjustable along the length of the member 10. The cuffs 12 and 13 function as hinges or fulcrums so that the apparatus 100 may bend at the exact required hip and knee joint positions of a given patient.
In addition, the apparatus 100 may include an outer upper shell 21 which is made of elastic material. In the embodiment of
Use of Apparatus to Change Body Positions
The method for changing a patient body position using the inflatable bed apparatus 100 operates as follows. Prior to placing the patient on the apparatus 100, the multiple identical parallel inflatable sacs 8 are inflated to a desired pressure using the pressure control assembly 17. Next, the patient is placed on the upper surface of the apparatus 100 or on top of the cover 21 so that the patient is equally distributed on either side of the longitudinal axis AA. Then, in accordance with a rehabilitation program formulated for the specific patient's requirements, the apparatus 100 moves the patient into various positions or along various trajectories by varying the pressure in the sacs 8 and 9 (if present) and/or in the members 4A, 4B, 5A, 5B, and 10 so that a desired pressure distribution is achieved on the body or on regions of the body such as the spine, the left and right portions of the torso and the legs. In particular, in order to manipulate, the spine into given positions or along given trajectories and with varying amplitudes, it is necessary to inflate and/or deflate multi-layered inflatable pneumatic levers 4A, 4B, 5A, 5B, 6, 7, and/or 15 in a predetermined and sequenced order using the pressure control assembly 17. Furthermore, in order to turn the whole body from side to side in along a given or desired trajectory and with varying amplitudes, it is necessary to inflate and/or deflate the multi-layered inflatable pneumatic levers 4A, 6, 7, 15A, 5A or 4B, 6, 7, 15B, 5B in a predetermined and sequenced order using the pressure control apparatus 17. In order to move the torso from side to side, it is necessary to inflate and/or deflate multi-layered inflatable pneumatic levers 4A, 4B, 6, 7, 15 in a predetermined and sequenced order using the pressure control apparatus 17. In order to move the legs into various positions or along various trajectories, it is necessary to inflate and/or deflate multi-layered inflatable pneumatic levers 5A, 5B, and 7, in a predetermined and sequenced order using the pressure control assembly 17. After the procedures have been carried out, the air may be pumped back out of the air sacs and pneumatic levers.
