Description

Exercise Device

The present invention relates to an improved device for providing assistance with physical rehabilitation and general exercise.

The present invention can be used to provide assistance with any suitable type of exercise or for body part or injury specific rehabilitation, including assisting with activation of spinal and trunk stability muscles for patients with lumbar or pelvic problems. It can also be used as an adjunct to enhance balance reactions and proprioceptive exercises for patients with lower limb problems. It can also provide assistance with activation and improved endurance of shoulder stability muscles and guide functional upper limb positioning. It can also help to improve motor and proprioceptive function in patients with specific neurological disorders. Moreover, the present invention can help to improve sensory motor function for patients having developmental or perception problems, and can provide assistance with vestibular balance dysfunction. Variations in application will facilitate muscle strengthening or enhance fine motor control and coordination.

The present invention will also provide a broader application for general health and fitness and health promotion. Many of the key aspects of rehabilitation such as stability, balance and co-ordination are also beneficial in this domain. Combining the device with existing exercise and fitness regimes will benefit these factors as well as endurance and muscle strengthening.

In order to achieve rehabilitation of the body for example, it is known for the user to repeatedly throw and catch a ball, manipulate a rope or flexible bars or lift or move weighted objects. Alternatively, they can repeatedly rotate a hoop around their arm, or use weight bearing exercises as part of the rehabilitation process. There is also available, a rehabilitation system known as Thera-Band ®, which is an elastic device which can be stretched by the patient in order to improve strength in the various muscles of the body.

Despite being useful means for providing assistance with physical rehabilitation, exercise, strength building and muscle development, the above known devices and methods present disadvantages including inability to achieve improvement in fine motor control, co-ordination and stability muscle activation. Moreover, the above known devices and methods are focussed on one particular injury or pathology at a specific stage of rehabilitation. Further, the user is not provided with input regarding whether they are carrying out the exercise correctly.

An aim of the present invention is to provide a device which overcomes or at least alleviates the problems associated with known devices such as those discussed above.

In particular, it is an aim of the present invention to provide an improved device for providing assistance with physical rehabilitation, exercise, fine motor control, coordination, stability muscle activation, muscle strengthening and endurance.

In accordance with the present invention there is provided a device suitable for providing assistance with physical rehabilitation or exercise comprising:-

(i) a hollow first member defining a first enclosure; and

(ii) a second member disposed within said first enclosure,

wherein said second member is movable within said first enclosure.

This provides the advantage that the user is able to carry out improved exercise in three dimensions, in a bespoke fashion according to the region of the body under rehabilitation. For example, the user can rotate the device or move the device back and forth or from side to side, in a way such as to cause the second member to move around within the hollow first member in a predetermined fashion. By means of example, the device could be moved around in a way such as to cause the second member to rotate following a circular path within the hollow first member. In this way, the user can perform exercises necessary for rehabilitation for example, whilst being able to see that they are carrying out the exercise correctly by means of observing the movement of the second member within the first enclosure.

In this way, the patient is able to carry out the rhythmical movements which are a useful part of the rehabilitation process, thereby triggering a response in the stability muscles.

The device 1001 comprises a hollow first member 1003, with a second member 1005 disposed within the first enclosure A"". The second member 1005 is freely movable within the first enclosure A"".

The hollow first member 1003 comprises a first hemispherical portion 1003a and a second hemispherical portion 1003b. As can be clearly seen from Figure 1 1, the hollow first member 1003 is spherical in configuration, whereby the first 1003a and second 1003b hemispherical portion are disposed relative to each other in a clamshell fashion.

As can also be clearly seen from Figure 11, the second member 1005 is spherical in configuration.

The device 1001 further comprises first 1099 and second 1 100 attachment means, disposed at opposite sides of the hollow first member 1003. The first attachment means 1099 is adapted to allow for selective attachment of a first end 1 102a of a strap 1 102 to the hollow first element 1003. In particular, the first end 1 102a of the strap 1102 comprises a first threaded element 1 104a, and the first attachment means 1099 comprises a corresponding engagement element (not shown) which together facilitate the selective engagement of the first end 1102a of strap 1 102 with the hollow first member 1 103.

The second attachment means 1100 is adapted to allow for selective attachment of a second end 1 102b of the strap 1102 to the hollow first element 1003. In particular, the second end 1 102b of the strap 1 102 comprises a second threaded element 1 104b, and the second attachment means 1 100 comprises a corresponding engagement element (not shown) which together facilitate the selective engagement of the second end 1102b of strap 1 102 with the hollow first member 1 103.

The provision of the first 1099 and second 1 100 attachment means provides the user with added versatility in terms of being able to add and remove the strap 1 102 from the first hollow member, and replace it with, for example, elongate handles, U-shaped handles etc., when required. In this case, the alternatives, i.e. elongate handles and U-shaped handles would have identical threaded elements to those of the strap 1 102 and in this way, the strap 1 102 and various handles would be interchangeable in accordance with the requirements of the user.

It is to be appreciated that the strap 1102 has an adjustable length to adapt to the requirements of the user.

In order to use the device 1001, the user inserts their hand under the strap 1102 and grasps the hollow first member 1003, which facilitates the user being able to hold the device 1001 with one hand. They can then carry out the appropriate exercises in accordance with their exercise or rehabilitation regime.

It is also to be appreciated that the presence of the first 1099 and second 1 100 attachment means spanning the first 1003a and second 1003b hemispherical portions helps to maintain the first 1003a and second 1003b hemispherical portions in position relative to each other such that together they form a spherical shape. In particular, the first 1099 and second 1 100 attachment means help to lock the first 1003a and second 1003b hemispherical portions in position relative to each other.

Referring now to Figure 12, a tenth embodiment of a device suitable for providing assistance with exercise for physical rehabilitation and muscle development is represented generally by reference numeral 2001.

The device 2001 comprises a hollow first member 2003 comprising a first hemispherical portion 2003a and a second hemispherical portion 2003b. As can be clearly seen from Figure 12, the hollow first member 2003 is spherical in configuration, whereby the first 2003a and second 2003b hemispherical portion are disposed relative to each other in a clamshell fashion. The device 2001 further comprises first 2099 and second 2100 attachment means, disposed at opposite sides of the hollow first member 2003. The first attachment means 2099 is adapted to allow for selective attachment of a first elongate handle 2009 and the second attachment means 2100 is adapted to allow for selective attachment of a second elongate handle 2011, for example by means of a screw thread arrangement similar to that described with reference to Figure 11.

The device 2001 further comprises a spherical second member 2005 disposed within the first enclosure Y, similar to the second members of the other embodiments, but for the provision of elastic means, which attaches the second member 2005 to the interior of the hollow first member 2003. In particular, a first elastic element 2999a is attached at one end to the second member 2005 and at the other end to the interior of the hollow first member 2003 in the vicinity of the first attachment means 2099. Further, a second elastic element 2999b is attached at one end to the second member on the opposite side to the first elastic element 2999a, and at the other end to the interior of the hollow first member 2003 in the vicinity of the second attachment means 2100.

In this way, the second member 2005 is substantially freely movable within the first enclosure Y in that it is able to move to an extent, but is anchored by means of the first 2999a and second 2999b elastic means, which limit its movement and prevent it from being able to move completely freely within the first enclosure Y.

In order to use the device 2001, the user grasps the first 2009 and second 201 1 handles and is able to carry out the appropriate exercises in accordance with their exercise or rehabilitation regime. In particular, the second member 2005 is able to oscillate vertically, laterally or in circles as the user moves the device 2001.

In order to prevent the first 2999a and second 2999b elastic means from becoming tangled, the first 2999a and second 2999b elastic means could be attached to the second member 2005 by means of a rotating element (not shown). Use of the device 2001 provides an oscillatory effect, which provides an alternative therapeutic effect to that provided by the previous embodiments. The device 2001 is convenient and safe to use in confined spaces such as in the home environment.

It will be appreciated by persons skilled in the art that the above embodiments have been described by way of example only, and not in any limitative sense, and that various alterations and modifications are possible without departing from the scope of the invention as defined by the appended claims.

By means of example, the device could further comprise a motion sensor for sending a signal representative of the motion of the device to a remote transceiver adapted to analyse the motion of the device.

By means of further example, the hollow first member could comprise a plurality of visual representations of various paths (not shown) on its exterior surface, such as a wave-like pattern, whereby the user manipulates the movement of the second member along a particular path as part of the rehabilitation process. The visual representation of the path could be defined by a plurality of LEDs defining the various visual representations of said paths, whereby the LEDs defining a particular visual representation of a path are selectively activated, thereby highlighting a particular visual representation of a path for the user to negotiate with the second member.

By means of further example, the hollow first member could comprise a plurality of regions, each region defined by a plurality of LEDs, whereby the LEDs defining a region are selectively activated, thereby highlighting that particular region. In this way, the user is provided with visual instructions as regards whereabouts to maintain the second member within the first enclosure, for a period of time.

By means of further example, the hollow first member could also comprise an electromagnet disposed within the first enclosure, whereby at least a portion of the second member comprises magnetic material. In this way, upon activation of the electromagnet, the user is faced with a more difficult task to control the movement of the second member within the first enclosure by means of manipulation of the device, against the attractive force between the second member and the electromagnet.

By means of further example, the hollow first member could be inflatable and one-piece in nature, with the second member being disposed inside the hollow first member. This provides an option which is inexpensive to manufacture as well as having improved durability. This version of the device would generally preclude the user from being able to selectively gain access to the first enclosure, in which case a suite of devices, each having differently sized / weighted / configured second members, could be provided to the user.

By means of further example, the second member could be adapted so that it illuminates in the event that it moves within the first enclosure, thereby providing the user with visual feedback as they manipulate the device. This is particularly advantageous in the event that the user has hearing difficulties or perception problems.

Moreover, the device could further comprise one of a hook and loop fastener attached to said hollow first member, and a user attachment means, for example a glove, wherein said user attachment means comprises the other of a hook and loop fastener, whereby said hollow first member is attachable to said user attachment means by means of said hook and loop fasteners, which may be Velcro ® for example. This is particularly advantageous in the event that the patient suffers from loss of grip function due to motor or sensory problems, for example.

It is also to be appreciated that whilst the main focus of the description of the above embodiments has been on rehabilitation of the shoulder region of the body, the device could be used for the rehabilitation of any suitable part of the body, for example the hand or the wrist. In the case of the hand or the wrist for example, the embodiment of Figure 1 could be used, appropriately sized in order to be able to comfortably fit inside the grip of the hand of the user. Moreover, it is to be appreciated that the device could be supplied to the user with differently sized/weighted/configured second members and/or fifth members, according to the rehabilitation requirements for a particular user. By means of example, the user could utilise the device with a heavy, metallic second member which is coated in rubber, or alternatively they could select a relatively lightweight plastic second member. The clamshell configuration of the hollow first member and/or the hollow fourth member facilitates the access into the first and third enclosures respectively in order to change to a differently sized/weighted/configured second member and/or fifth member according to the requirements of the user.

The device of the present invention is adaptable to incorporation into many different exercise programmes focussing upon different parts of the body according to the requirements of the user.

Moreover, the device of the present invention can be utilised in Pilates programmes as well as other types of health and fitness programmes, not necessarily focussed upon rehabilitation.
