Description

WO91/1 ~ 3 PCT/US91/04319 2 0 ~ 6 Description Exercise and Rehabilitation Device and Method 5 Technical Field n The present invention relates generally to , exercising devices and, more particularly, to a novel device which provides for strengthening the lower back without twisting or compressing the vertebral column , lO of the user~

-~- Back~round Art.
, The American Back Society has determined that `` eight out of ten Americans suffer from some form of l5 lower-back pain. In 1988, the American business community lost about 20 billion dollars because of insurance claims for loss of work, due to back injury ` and/or pain. In fact, compensation claims involving back problems represented a third of all job related 20 compensation claims paid out by insurance companies that year, and the average back injury compensation claim amounted to S6.000. Treatment for back pain ~, ' ranges from complicated surgery to a simple drug prescription. However, growing evidence indicates ~, 25 that proper exercise is the best long-term solution ~d for back ailments.
Some back problems can result from hyperextensions occurring during improper physical exercises. Extension of the spine or vertebral column 30 occurs when it is returned to the normal anatomical po8ition from the flexed (bent forward) position.
Hyperextension of the spine occurs when the extension movement goes beyond the normal anatomical position ~ ' ' ~` 35 . .

-2- 2 0 ~ 7 6 (in a backward direction), usually recognized by additional compressing and arching of the spine.
Hyperextensions, and especially excessive hyperextensions, can be dangerous, since compression of the spine is involved. This can lead to fractures of the compressed vertebrae occurring as a result of the forces acting on the back of the person.
Bending incorrectly and lack of strength and flexibility in the muscles that support the spine 1~ continues to be a chronic problem. Stress is also a major contributor to back pain, since it causes a tensing and tightening of already weak muscles.
The simplest solution is to strengthen the back by exercise of the muscles of the hip and back. There are two major types of lower back strengthening ;~ apparati that are used: (1) hyperextension devices and ~; (2) back extension devices.
When a hyperextension device is used, an individual lies over the device with his face down, bending the torso in the direction of the ground and then subsequently raising the torso. The lower part of the body is kept stationary by a foot attachment.
An important part of this exercise is to raise the torso upwardly toward and (improperly) beyond the Z5 position parallel to the ground without compressing , the spine. However, in view of the design of this rd` apparatus, it is difficult to properly execute this exercise without hyperextension and the resulting substantial compression of the spine. To alleviate 30 this condition, special training of a user such as, for example, rounding out the back so as to eliminate compression of the spine, while performing this exercise, is necessary to ensure correct development of the lower back muscles and to decrease risk of ~, :

~', .,, -.

'! ' WO 91/19543 PCT/US91/04319 3-- 2 0 3 ~ ~ 7 6 -~ injury to the spine. Lack of such training makes it ; very difficult for an unconditioned person to use the hyperextension apparatus extensively without ; substantial risk of injury. Substantial hyperextensions and arching of the back also can bring on, or increase, pressure on the nerves. This can be a factor of back pain and, if the sciatic nerve is - impinged, can lead to pain down the legs.
When the back extension machine is used, an individual in the seated position presses on part of the machine with his or her back, so that the upper part of the body goes from a position substantially perpendicular to the lower part of the body to a ~, position in which the whole body is substantially straight. A user of this machine conducts exercises in the seated position while the spine is already compressed. When the back presses on part of the , machine, the spine compresses and arches substantially further, especially if the resistance is great. This can lead to excessive compression and shearing forces acting on the vertebrae and disks, injuring the back of a person.
Accordingly, it is a principal object of the present invention to provide an exercise device and method using the same which can be used to strengthen the lower back of a user without compression, hyperextension, or twisting of the spine of the user.
....
Another object of the in~ention is to provide such device and method which are relatively easy and 30 comfortable to use.
An additional object of the invention is to ~1 . provide such a device that is readily adjusted to ;~ accommodate users of different sizes.

A further object of the invention is to provide such a device that is easily and economically constructed.
Other objects of the present invention, as well as particular features and advantages thereof, will be elucidated in, or be apparent from, the following description and the accompanying drawing figures.

Disclasure of Invention ;i lO The present invention achieves the above objects, among others, by providing, in one preferred embodiment, a device for strengthening the lower back of a user which includes a frame having a horizontal member for support of the hips of the user and having, spaced apart from the hip support, a horizontal platform for support of the head, shoulders, and upper chest of the user. The user places himself upon the frame so that his hips, head, shoulders, and upper chest are supported, with his legs hanging vertically from the hip support. The chest of the user is largely unsupported to permit comfortable and easy breathing. The strengthening motion comprises raising the legs from the vertical position to the horizontal position and again to the vertical position. There is little or no risk of injury to the vertebral column, due to the fact that the vertebral column is stàtionary when the exercise is executed. In another preferret embodiment, a hydraulically operated hin8ed member effects the above leg movement to provide therapy for disabled osers.

';,.'' 6 20~7 Best ~ode for Carryin~ Out the Invention Referring now to the Drawing, in which the same or similar elements are given consistent identifying numerals throughout the various figures thereof, 5 Figure 1 depicts a device for use in strengthening the lower back, constructed according to the present invention, generally indicated by the reference numeral 10, with a user thereon.
Device 10 includes an upper horizontal frame ? lo member 12 having a support platform 14 freely movable ,i, fore and aft thereon. Device 10 further includes a lower horizontal frame 16 for support of said device on a floor or like supporting surface. Upper frame 12 ; is mounted on a first pair of telescoping le~s having 15 upper sections 22 fixedly attached to the upper frame and a lower sections 24 fixedly attached to lower frame 14. A similar, second pair of telescopin~ legs having upper sections 26 and lower sections 28 movably 1 joins upper horizontal frame member 12 to lower ; 20 horizontal frame 16. The height of upper frame 12 and support platform 14 from lower horizontal frame 16 is selectively adjusted by means of a conventional worm gear mechanism 30.
i Fixedly and horizontally disposed at the rear of 25 upper horizontal frame 12 is a rounded, cushioned hip support 40 generally disposed somewhat rearwardly of upper leg sections 22, so that device 10 can acco-modate users with large thighs.
Referring also to Figures 2 and 3, support 30 platform 14 includes a resilient pad 42 fixed thereon, the pad having an oval opening 44 formed therethrough, and the pad sloping from a high point at the forward ent of the psd to a low point at the rear end of the .lj ... .

pad. Attached to the forward end of upper horizontal frame member 12 is an adjustable hand grip structure 50 telescopingly extending forwardly of the member and selectively fixed in position by means of hand screws 52. Referring particularly again to Figure 1, fixed hand grips 54 (only one visible on Figure 1) are attached to upper leg sections 26 as shown.
Completing the description of the major elements of device 10, there is provided a horizontal foot stand 56 fixedly attached at the lower ends of lower leg sections 24.
In use, the user, generally identified by the reference numeral 60, steps upon foot stand 56 and bends over hip support 40 to the position shown on Figure l, with the central portion of the user's face inserted into oval openin~ 44. Placing the face in oval opening 44 assists in proper orientation of user 60 on device lO, as well as providing comfortable support for the head of the user. While moving to the position shown, the user may find it convenient to grasp fixed hand grips 54, but while using device 10 for back strengthening, the user may find it more comfortable to grip adjustable hand grip structure 50 forward of the user's head. Since the length of the legs and the length of the torso will vary from user to user, depending on age, sex, etc., mechanisms 30 and 32 will be adjusted for the comfort of each user.
Hip support 40 will be adjusted high enough that the feet of the u9er can be easily slid off foot stand 56.
Once positioned as shown, the user is supported at the hips by hip support 40. The shoulders, cl8vicular area, and face of the user are supported by resilient pad 42, while additional support of the upper che~t may be provided by sternum support 46.

W091/19~3 PCT/US91/~319 -~i 2033~76 Thus positioned, the lower portion of the user's chest i9 unsupported, permitting comfortable and easy breathin8. Furthermore, in the position shown, the whole vertebral column is stationarily positioned and is in correct, natural alignment and curvature, without compression thereof and the back muscles are relaxed when the feet are in a downward pointing position. Because of the bent position of the user's body, the lower back muscles, which are to be strengthened during the exercise, are somewhat isolated from the rest of the back muscles. The gripping of hand grip structure 50 or of fixed hand grips 54 helps stabilize the position of the upper torso of user 60 during exercise.
When the back strengthening exercise begins, the user inhales and raises the lower extremities to a position substantially parallel to the ground, as shown in broken lines on Figure 1. On upward ascension of the lower extremities, the user preferably points the toes downward into plantar flexion. On descension, the toes preferably go into dorsi flexion during the release, while the user exhales.
When performing the exercise, the user's chest ; 25 freely expands and contracts within the unrestricted area between hip support 40 and platform 14, thus -, permitting the user to breathe easily and freely.
Such breathing ensures an adequate supply of oxygen to the lungs, eliminates discomfort, and helps the user to exercise efficiently. Having support platform 14 movably disposed on horizontal frame member 12 permits 1 movement thereof during the exercise, thus affording ; user 66 a high degree of comfort and further assuring .

_9_ that the vertebral column is neither expanded nor ; compressed.
Figure 5 depicts device io modified for use in physical rehabilitation programs where injury or illness has seriously limited the range of movement of the body, or its strength, with respect to muscles of the lower back and hip, the modified device being identified generally by the reference numeral 10'.
Device lO' includes a leg support 70 rotatable about a shaft 72, the shaft being fixedly attached to device lO' by means of flange 74 on the right side of device ; lO'. It will be understood that an identical shaft and a flange (neither shown) are provided on the left side of device lO'. Leg support 70 is rotated by means of a conventional hydraulic cylinder 76 having its distal end rotatably attached between upper leg sections 22, with its shaft 78 extendable to rotate the leg support from its vertical position (solid lines) to its horizontal position (broken lines), thus raising the legs of the patient. The controls for hydraulic cylinder 76 are conventional and may be arranged so that either patient 66 or an attendant can operate the cylinder. The controls may provide for selectively adjusting the speed and/or extent of rotation of leg support 70.
When device lO' is used in a rehabilitation program, careful attention must be given to the prevention of over-extension of the lower back muscles which may have been subject to disease or injury. The : 30 process of exercising must not be permitted to aggravste the original condition.
In order to use device lO' for rehabilitation purposes, patient 66 is placed on the apparatus in the position similar to that shown, which is identical to , ' ~ . .

: -10-that of user 60 shown on Figure 1. To raise the legs, hydraulic cylinder 76 is activated to gradually lift leg support 70. After leg support 70 reaches a predetermined eleva~ion, the direction of motion of ; 5 the mechanism is reversed and the legs are gradually lowered to the initial position. Such exercise can be repeated with different speeds of motion and different degrees of elevation of the legs.
;~
In order to have control over the intensity of a rehabilitation program, the hydraulic controls can be -~ adjusted to vary the level of support provided by leg support 70 to the legs. For example, leg support 70 can provide the lifting force to move only 50 percent of the weight of the patient's legs, the remaining 50 percent of the required force being provided through ` exercise of the patient's own muscles. The level of support provided by the regulating mechanism is usually greater at the initial stages of rehabilitation and can be reduced as the condition of ' 20 the patient improves.
During the rehabilitation exercise, the lower extremities of a physically impaired person are moved upwardly into a hip extension to manipulate the muscle groups of the gluteal and lower back. The regulating mechanism sssociated with the leg support 70 enables the patient to raise and lower his or her legs with different degrees of assistance.
, Figures 6-8 illustrate an alternative hip s support 90 which may be employed with devices 10 and 30 lO'. Hip support 90 is a generally rectilinear padded member which is disposed rearwardly of upper sections 22 and which is disposed on a shaft 92 to permit a `, slight amount of rotational motion as is indicated bycompsring-the relative positions of hip support 90 on 35 Figures 6 and 7. Thus, hip suppart 90 afforts a , .~.

somewhat greater degree of support and comfort than does hip support 40 shown on Figures 1, 2, and 5. Hip support 90 includes a cut-out portion 94 for the increased comfort of male users.
- 5 Figures 9-ll illustrate another alternative hip support which may be employed with devices 10 and 10', generally indicated by the reference numeral 100. Hip support 100 includes a semiresilient body 102 having embedded therein a reinforcing plate 104. Fixedly attached to, and rising upwardly from, reinforcing plate 104 are two mounting tabs 110 and 112. On Figure 9, hip support 100 is shown rotatably mounted to the proximal end of upper horizontal frame member 114 at the distal ends of mounting tabs 110 and 112.
It can be Reen from Figure 10 that hip support is V-shaped in plan view, with the sides of the V forming an angle of about 130 degrees.
Hip support 100 includes an oblong front portion ~ 120 joined to a rounded rear portion 122 at the narrow ; 20 part of the oblong portion so as to form a first trough 124 in the upper surface of the hip support extending transversely from one side of the hip support to the other. A second trough 126 is defined in the upper surface of hip support 100 along the central axis thereof and extending from a notch 128 defined in the front edge of the hip support to the '` rear edge of the hip support.
First trough 124 is provided to accommodate ~ therein the pelvic crest of a user and rounded rear ;~ 30 portion 122, having a diameter of approximately two inches, is provided to conform to the space between the pelvic crest and the pubis of a user. Second trough 126 accommodates the lower abdominals of the user for comfort. The distance between the root of .

Body 102 of hip support 100 may be constructed of medium density, foamed polyether polyol as furnished by Cook Composites ~ Polymers, Burlington, Indiana. When foamed, the material forms a skin of about 0.030-inch thickness. The surface of body 102 should have a high coefficient of friction, say, on the order of 0.7, or be slightly textured to maintain placement during exercise. Reinforcing plate 104 and mounting tabs 110 and 112 may be constructed of any suitable relatively rigid material such as steel.
Figures 12 and 13 illustrate an alternative semiresilient support platform, generally indicated by the reference numeral 150. Support platform 150 includes a first opening lS2 defined generally centrally therethrough to accommodate the head of a user. Defined through support platform 150 above first opening 150 is a second opening 154 separated from the first opening by a relatively narrow bridge portion 156. Second opening 154 and bridge portion 156 are provided to accommodate heads of different heights by means of the deformation of the bridge into the second opening. Support platform 150 may be constructed of the same material as hip support 100.
! Figures 14 and 15 illustrate another embodiment of sn exerci~e and rehabilitation de~ice according to 30 the present invention, generally indicated by the reference numeral 200. Referring principally to Figure 14, de~ice 200 includes an upper frame member 202 on which ia horizontally slidingly disposed a aupport platform 204 which may be selectively fixed in ' ~

place by means of clamp 212. At the proximal end of upper frame 202 is rotatably mounted a hip support 206 which is identical to hip support 100 shown on Figures 9-11. A handle structure 208 is telescopingly mounted to the distal end of upper frame member and is selectively adjusted by means of threaded knob 210.
Device 200 further includes a lower horizontal frame member 220 joined to upper fra~e member 202 by means of two telescoping legs 222 and 224. Telescoping legs . 10 222 and 224 are actuated, and thus the distance between upper and lower horizontal frame members 202 and 220 can be adjusted, by means of electro-mechanical actuators 230 and 232.
Telescoping legs 222 and 224 are fixedly attached at their lower ends to lower horizontal frame member 220, but are rotatably attached at their upper ends to upper frame member 202 such that the upper frame member can be rotated from the position shown on : Figure 14 to the position shown on Figure 15 by means of actuation of an electro-mechanical actuator 226.
Electro-mechanical actuators 230 and 232 are controlled by "UP" and "DOWN" buttons disposed in the distal end of upper frame member 202 as shown on Figure 16 or by "UP" and "DOWN" buttons disposed in handle structure 208 as shown on Figure 17. Electro-mechanical actuator 226 is controlled by "RAISE" and "LOWER" buttons disposed in handle structure 208 as . ~hown on Figure 18.
Referrin8 now primarily to Figure 15, when a .. 30 person (not shown) wishes to use de~ice 200, the device is placed in the position shown on Figure 15 . and the person approaches the device and stands with his hips touching hip support 206.

Alternatively, the person -; 5 may align his navel with the root of notch 252 defined in the front edge of hip support 206. Next, the person uses clamp 212 to adjust support platform 204 and inserts his face into opening 254 and then uses knob 210 to adjust handle structure 208. Then, the person presses the "LOWER" button on handle structure 208 (Figure 18) to rotate upper frame member 202 to the position shown on Figure 14 with the person thereon in the position shown on Figure 1. Finally, the person presses the "UP" button on handle structure 208 (Figure 17) to raise the upper platform a few inches so that the feet of the person will clear the surface on which device 200 is supported. Exercising of the lower back, as described above, can now begin.
At the end of exercising, the person presses the 20 "DOWN" button on handle structure 208 (Figure 17) to lower his feet to the surface on which device 200 is supported and then presses the "RAISE" button on handle structure 208 (Figure 18) to rotate upper frame member 202 to the position shown on Figure 15. The 25 per90n may now wslk away from device 200.
Devices 10, 10', and 200 of the present invention facilitate extensions of the lower back and hip areas versus extensions of the upper torso. This is a substantially safer exercise than those disclosed 30 by the prior art, since possibility of hyperextension or compression of the vertebral column is substantially reduced, if not totally eliminated.
