Definitions

  • This invention relates to muscle tone promotion for h ⁇ mans including an arrangement far footwear which provides muscle tone promotion and also a method of assisting muscle tone promotion.
  • the human body has a number of muscles which are used and activated for various and sometimes different purposes.
  • corset muscles There are, among other muscles, a set of muscles often referred to as the "corset” muscles which are especially of value in- stabilising the spine and which are activated only in certain circumstances which will normally not coincide with those muscles that might be exercised in conventional muscle strengthening exercising or activities.
  • THE PROBLEM TO WHICH THIS INVENTION IS DIRECTED
  • the problem to which this invention is directed relates to the difficulty of ensuring that a vital set of muscles are switched on from time to time. A person, unless well trained to recognise it, will not know whether such corset muscles are switched on or not although it is known that a number of conventional physical actions for instance climbing stairs or walking quite quickly with long steps does have this beneficial effect although walking with quick short steps does not appear on those persons tested so far to switch these muscles on.
  • An object of this invention is to provide a means in one case and a method in another case whereby a human can be assisted in having their corset muscles toned up or increased in tone.
  • shoe should be read as a generic reference where the context admits to footwear which may include any one of boots, shoes, sandals, thongs, or slippers.
  • a trigger that has provided and maintained activation of the corsei muscles for a number of people is for a person to have, for each foot, a foot support with a transverse slope with a higher side being on the inside of a Jeg and the lower side being on the outer side in each case.
  • This can be achieved by providing a base on which a person stands or it can be an inner sole within shoes or it can be a slope designed into the soles of a pair of shoes.
  • the degree of slope can be quite modest and on trials that we have conducted so far, the effect appears to be useful where there is a slope anywhere from 1 ° to 6° with respect to a horizontal.
  • corset muscles are to be distinguished from other muscles which might be used for as conventional discretionary activated purposes where for instance efforts involving conventional strength might be used even with traditional exercises.
  • corset muscles seem conventionally not to be always or reliably at least to be switched on in such exercises although it is known that there may be other exercises which are dedicated to detecting and effecting activation of these muscles in a discipline for instance "Pilates”.
  • the effect still occurs at least in those examples we have trialled where there is a forward slope where for instance the shoe may be a high heeled shoe or even a conventional men's shoe with a high heel or even where there are conventional shoes in which there is a slight forward slope which is to say it is higher at the back than the front.
  • the effect does appear to be countered if the slope is higher at the front of a shoe or item of footwear than the back.
  • the invention could be said to reside in a pair of shoes where a first shoe is a for a right foot of a wearer, and a second shoe is for the left foot of the wearer, each of the shoes having a sole shaped or having an insert within each respective shoe being shaped so that, when each shoe is located to be resting in a usual upright position on a flat and horizontal surface, the foot of a wearer of that shoe will have the foot supported at substantially all areas which contact the sole of the foot on a transversely orientated sloping surface whe r e the extent of the slope is within a range of from 1° to 6°, with an inner side of the shoe for each of the shoes being the higher side of the slope.
  • a pair of shoes including for each of a pair, a sole arid an upper attached to the sole, there being within each unit of the pair, an inner sole that has a thickness which is greater on an inner side of each unit of the pair and an outer side of each unit of the pair, so that an upper surface of both inner soles has a slope when resting on a horizontal plane that is within a range of from 1° to 6* of slope from an inner side to an outer side and along its effective length when viewed in cross section which cross section is transverse to a direction of elongation of the inner sole.
  • the invention could be said to reside in a support for both feet of a person standing where the support is adapted to rest on a horizontal surface and provide an upper support surface where there is a sloping surface for each respective foot where the siope for a left foot is within a range of from 1 degree to 6 degrees with a highest side being on an inner side of the support and where the slope for a right foot is within a range of from 1 degree to 6 degrees with a highest side being on an inner side of the support.
  • this could be said to reside in a method of assisting maintaining corset muscle tone of a person including the step of wearing a pair of shoes where a first shoe is for a right foot of a wearer, and a second is for the left foot of the wearer, each of the shoes have a sole shaped or having insert within each respective shoe being shaped so that when each shoe is located to be resting in a usual upright position on a flat and horizontal surface, the foot of a wearer of that shoe will have the foot supported at substantially all areas of contact of the sole of the foot on a transversely orientated sloping surface where the extent of the slope is within a range of from 1° to 6", within an inner side of the shoe for each of the shoes being the higher side of the slope.
  • the degree of slope is substantially constant along an effecting length of the shoe.
  • any slope in a forward to rearward direction of a shoe is only such that a "earward end of each shoe is higher than a forward end.
  • the corset muscles When the corset muscles are on, the set of the body does appear to be different and a very much higher resistance to being overbalanced by such applied pressure exists. This effect is believed to be caused through the action of our invention causing greater activity of core and other postural muscles together. The effect therefore is not limited to only the core muscles but a challenge to balance will also bring into play other muscles but if the core muscles are not active then there is this greater vulnerability.
  • a method of assisting maintaining corset muscle tone of a person comprising the step of putting on then wearing while walking, a pair of shoes where a first shoe is for a right foot of a wearer, and a second is for the left foot of the wearer, each of the shoes having a sole shaped or having an insert within each respective shoe being shaped so that when each shoe is located to be resting in a usual upright position on a flat and horizontal surface, the foot of a wearer of that shoe will have the foot supported at substantially all areas of contact of the sole of the foot on a transversely orientated s oping surface where the extent of the slope is within a range of from 1° to 6", within an inner side of the shoe for each of the shoes being the higher side cf the slope.
  • Fig 1 is a schematic cross section along a medial line of a shoe according to a first embodiment where there is an insert within an otherwise standard shoe
  • Fig 2 is a schematic cross section along a medial line of a shoe according to a second embodiment in which the transverse slope is integrated into the sole
  • Fig 3 are the respective cross sections as shown in figure 1 ,

  • Fig 1 1 is a table of results using the balance test where the extent of slope and distinction between use of the slope with one foot as compared to two is compared this being for Michael a 52 year old male, and
  • Fig 12 is a plan of a shoe sole illustrating approximate positions in which the foot of a wearer will contact the inner upper surface of the shoe. DESCRIPTION OF THE EMBODIMENTS
  • the shoe in Figure 1 includes an upper 1 and a sole 2.
  • an insert 3 which is a sheet of pliable material (EVA "ethylene-viriyl acetate” is a suitable material for this purpose) which when laid on a horizontal surface has an upper surface which from one side to an opposite side has a consistent slope in this case 2°.
  • EVA ethylene-viriyl acetate
  • the thickness at the thinnest side is sufficient to withstand reasonable wearing by a user and the resiliency is such that this slope will be substantially maintained with a person standing on the material.
  • the thickness is also chosen so that its insert within an ordinary shoe will not , unduly affect the overall size of the shoe so making it uncomfortable from being too tight to a wearer where the shoe previously was satisfactory.
  • the Z" slope has been chosen as being somewhat midway between 1 " and 6* which range has been established by experimentation some results of which are listed in the tables in Figures 8 through 11 and as little as reasonable to get the effect without it being uncomfortable to a majority of users.
  • the pliable nature of the insert 3 will normally be able to be inserted into a shoe where it is appropriately shaped to follow an inner lower perimeter of the inside of the shoe 1 but it will not provide any wraparound stabilising shape either at the arch area of the foot or around the heel or around an underneath of the front of the foot.
  • FIG. 3 now shows the respective cross sections along the lines AA, BB 1 CC and DD.
  • Section AA shows a cross section through four of five toes and illustrates simply the extent to which the toes at least to each side rest on the infill 3.
  • Section BB is a cross section through the front of the foot
  • section CC is through a portion of the foot showing the arch and as well be seen in the drawings, this means that most of the foot is above any supporting surface of the infill 3.
  • FIG 2 in many ways is the same as in Figure 1 except in this case th ⁇ sole 4 of a shoe 5 has the same effective features as in Figure 1 but the slope is integrated into the structure of the sole 4.
  • FIG 5 this is a perspective view of an inner liner of wedge shape which in this case is for a right foot but for this invention there would be two of these one for the left which would mirror the one shown which is for the right foot.
  • This unit 8 then has a consistent slope along its full length of 2° and the material from which it is made is a pliable material such as a soft polyurethane plastic material or a rubber material formulated to be relatively pliable but not deformable to the extent that it would naturally collapse and wraparound the foot of a wearer.
  • a pliable material such as a soft polyurethane plastic material or a rubber material formulated to be relatively pliable but not deformable to the extent that it would naturally collapse and wraparound the foot of a wearer.
  • Figure 6 is a side view illustrating in an exemplary way a typical altered posture when someone is wearing the modified shoes as compared to when someone is not.
  • Figure 7 simply illustrates typical muscle sets and identifies particularly the transverse abdominus which are considered to be the corset muscles, and separately identifies the rectus abdominus, gluteals, vastus lateralis and tibialis anterior.
  • the first of these is for Fran a 52 year old woman. It will be noticed that there is some muscle tone exhibited at the -1.5 degrees which is a slope with the outer side higher than an inner side whereas this is reduced at 0 degrees to 6 kgs.
  • the prime effect in this instance lies between +1.5 degrees through to +4 degrees.
  • There is advantage to a user if the slope is smaller as it is not then apparent and is more comfortable.
  • the range of from 1 degree to 6 degrees is found to fce a slope range that provides assistance in the effect for many people. However a range of from 1.5 degrees to 5 degrees is likely to include more peop e and a range of approximately 2 degrees is further likely to include even more people.
  • the subjects in each case also had no shoes on so that the reaction was only to slope as such and they were positioned for each with a big toe against a front stop and a ball of the foot in each case against a side stop.
  • the resistance for Fran indicates that the arrangement is providing a switching of the corset muscles through approximately 1 degree to slightly higher than 4 degrees. For the rest of the tests it shows that with an arch support high or with a front higher than a back or the slope being for one side only the muscle tone is maintained iow in that the resistance measured is all below 8.3 kgs cf at least 12 Kgs anc above for the appropriate slopes.
  • the slope is not specified eg when the arch is high or low the inner as compared to an outer slope is set at 2 Degrees.
  • tone has been generally switched off by the reverse slopes eg with front higher than a back but there is some apparent partial return (32) with one side sloping only.
  • This lady agreed to try wearing innersoles consisting of an upper surface that was flat other than a 2% slope high on the medial edge for the whole length of the inner sole.
  • the upper surface of the soles of the shoes worn were substantially flat, the original inner sole with an arch support having been removed.
  • the purpose of this approach was to switch on to a greater extent the deep corset (core) muscles which stabilise the spine and maintain the curves of the spine.
  • core deep corset
  • Within a few weeks of wearing the innersoles daily and whenever shoes were worn her posture has visibly improved and she finds she stands upright automatically without conscious effort. The discomfort reported initially had gone within a few days. The muscles that were previously tender to palpation were no longer so and trigger points were not found. This effect has lasted for 52 weeks.
  • I ⁇ nersoles to be fitted to both shoes, were recommended consisting of an upper surface that was flat other than a 2% slope high on the medial edge for the whole length of the Inner sole.
  • the upper surface of the soles of the shoes worn were substantially flat, the original inner sole with an arch support having been removed.
  • the purpose of this approach was to enable the central nervous system to more effectively switch on the trunk muscles, including the core muscles, to provide spinal stability and to co-activate them with other postural muscles to maintain balance and better posture.
  • Innersoles were recommended to be worn when massaging.
  • the innersoles consist of an upper surface that was fiat other than a 2 degree slope high on the media) edge for the whole length of the inner sole.
  • the upper surface of the soles of the shoes worn were substantially flat, the original inner sole with an arch, support having been removed.
  • the purpose of this approach was to switch on to a greater extent the deep corset (core) muscles which stabilise the spine and maintain the curves of the spine.
  • core deep corset
  • the new innersoles conferred a greater resistance to balance challenges as described.
  • the original innersoles did not.
  • the combination of old and new innersoles did not improve resistance to the balance challenges.
  • the reasor for suggesting the inner soles was to increase activity of trunk muscles, including core muscles, and co-activation with other postural muscles. This would help with arising from a sitting position, help with stability when standing and walking. Also by helping maintain an upright posture, pressure on the fractured vertebrae and pain levels could hopefully be reduced. Since total bed rest was not required for treatment, increasing muscle activity when possible would help reduce any further muscle tone loss.
  • She is 166cm tall, 57.2kg, good fitness, Anglo Saxon and has arched feet. She has been wearing the innersoles for 6 weeks, 7 days per week at an average of 6-9 hours per day. She wears sneakers / boots with the innersoles and does not wear orthotics. She does mostly walking and gardening with the innersoles in. For the first week of using Strength Soles she noticed muscle pain in my buttocks and thighs - nothing serious but unusual. Then in the weeks that followed the discomfort began to disappear, and she began to notice that after lifting heavy items, although her back would immediately begin to protest, the recovery rate was becoming faster and faster.
