Definitions

  • the present invention relates to a device and a method for assessing correct alignment of an individual, particularly as regards the correct support and positioning of his body when the latter uses accessories such as sports accessories.
  • the human body is known to have imperfections which result in the general morphology being affected by a misalignment of the body.
  • the longitudinal axis of the body is usually not completely vertical and secondly the transversal axis at the level of the pelvis is not completely horizontal and thus not perpendicular to the vertical axis and possibly out-of-line.
  • Kinesiology is a form of science dealing with muscular tone (tonicity) and a feeling of well-being. It has thus been proved that there is a direct relation between muscular tone and good alignment and thus a correct balance of the skeleton. The moment the skeleton is correctly aligned, the user can put his own capacities to good use.
  • the invention provides a device and a method for determining correct alignment of an individual's posture as defined in the appended independent claims. Preferred or advantageous features of the invention are set out in dependent subclaims.
  • the present invention may offer a device making it possible comparatively, controllably and repeatably to measure the muscular tone of any individual so as to determine the best suitable wedges or other alignment accessories during an alignment operation.
  • the device of the invention may advantageously make it possible to dispense with the personal interpretation of the individual being tested, or the interpretation of a skilled practitioner, by using a relatively inexpensive item of equipment which is easy to use and occupies a small space.
  • the invention provides a device for controlling or determining the correct alignment of an individual's posture, in particular when equipped with a sports accessory, which comprises:
  • the sensor may advantageously be an actuator for measuring the force exerted with the thumb of the individual.
  • the force and action speed may be measured when the individual reacts to a signal.
  • the sensor may be a static sensor held in the hand for measuring the force exerted and the action speed of the thumb on the sensor when the individual is instructed to repeatedly exert a force on the sensor.
  • a device embodying the invention may advantageously be used in any of a number of ways, including the following preferred embodiments.
  • the individual may be instructed to apply as high a force to the sensor as possible in as short a time as possible (or as fast as possible).
  • the data acquisition unit then records the maximum force applied and the time taken to apply it.
  • the time measurement may begin at a small threshold force level rather than at zero force, to reduce errors.
  • the individual may be told to repeat this operation a predetermined number of times, such as 5, 10 or 15 times.
  • the time between two predetermined force values (a low value and a high value) may be recorded.
  • the individual may apply a force to the sensor each time a signal, such as a flashing light or an audible sound, is given.
  • the test then incorporates reaction speed.
  • the signal may be controlled by the data acquisition unit so that time from the signal to the maximum application of force could, for example, be recorded.
  • the sensor can be actively controlled by the data acquisition unit to apply a force to the individual's thumb or hand (for a hand-held sensor).
  • the sensor could incorporate an electromagnetic or pneumatic drive means or an inflatable bladder.
  • the individual would then be instructed to oppose the force applied by the sensor as quickly as possible when the sensor is actuated.
  • the data acquisition unit would again record the maximum force applied and the time taken to apply that force, or the time taken to reach a maximum threshold force.
  • the data acquisition unit advantageously evaluates an output parameter based on the force applied and the time taken to apply it.
  • the parameter is a measure of force (F) divided by time (t) or, particularly preferably, F 2 /t.
  • the parameter may be evaluated in any of a number of ways.
  • the parameter may be based on the recorded maximum force and a recorded total elapsed time, or on the time elapsed between the application of a minimum threshold force and the maximum force, or between predetermined low and high threshold forces.
  • the elapsed time may be measured from when the stimulus is given.
  • the data acquisition unit may continuously log the application of force during a test and evaluate the output parameter as the slope, or a best-fit slope, of a plot of force against time, or force squared (F 2 ) against time.
  • an output parameter is generated from each test.
  • an average of the output parameters can be calculated by the data acquisition unit, optionally discarding an extreme value or values of the output parameter, such as the maximum and minimum values from a series of tests.
  • the trigger may be the applied force rising through a predetermined threshold force or, in tests where the individual responds to a stimulus such as a flashing light or actuation of an active sensor, the time that the stimulus is triggered.
  • the senor may be considered to measure applied force or applied pressure. This does not affect the validity or handling of test results which are preferably not intended for comparison of one individual with another, but to assess the muscle tone of one individual when using different posture-enhancing accessories.
  • the invention may also advantageously provide a method for controlling or determining the correct alignment for the posture of an individual, consisting of the following steps:
  • Calibration preferably consists of carrying out at least one measurement, the individual preferably being barefoot on a flat surface so as to measure a value corresponding to a good muscle tone, and at least one measurement with the individual having one foot on an obstacle so as to measure a value corresponding to a poor muscle tone.
  • the individual is preferably made to undergo 10 tests, the two upper extreme and the two lower extreme tests being removed with an average being made of the remaining six.
  • the invention may find application in the testing of any posture-adjusting accessory, as the skilled person would readily appreciate.
  • Other portions of this document refer to the use of wedges; this is only one example of the application of the invention.
  • figure 1 is a perspective view of a device embodying the present invention
  • figure 2 is a symbolised view of the axes of a naturally non-aligned skeleton
  • figure 3 is a symbolised view of the same skeleton after correction leading to an alignment
  • figure 4 is a synoptic diagram of the stages for acquiring and processing the stored information.
  • the device of the present invention includes an acquisition unit 10, a sensor 12 and an electrical wire or optical link 14 for linking this sensor to the unit.
  • This physical link can be replaced by a wireless link if this is required for good ergonomics, links of this type being commercially available.
  • the acquisition unit includes a microprocessor 16 for running software to collect information measured using the sensor, to store it and to display it on an integrated screen 18.
  • This unit may also include an adapted outlet for diverting the information into a central unit of an office computer comprising further processing software.
  • the software may not only present the results of tests but also associate the wedges used for each test result by a graphic display. Moreover, the results can also be processed for presentation in the form of graphic diagrams, such as plotted curves.
  • the sensor 12 comprises a box or housing 20 adapted to be held in the hand.
  • a plunger 22 extends from the housing for applying the thumb.
  • the dimensions- are preferably chosen so as to be held by either an adult or a child.
  • the senor includes a sprung piston type activation button
  • FIG. 2 shows diagrammatically a skeleton with its mechanical elements, showing a different left foot 24 and right foot 26.
  • the individual is equipped with sport accessories, in this case rigid shoes 28, such as ski boots.
  • the longitudinal axis Y of this individual's skeleton is naturally slanted, which results in certain misalignments at the level of the pelvis and of the transverse axis X corresponding to it.
  • This axis X is not horizontal and, to compensate for it, hip distortions in the individual can be observed.
  • the individual picks up the sensor and acts several times on the plunger so as to determine an initial average value of their muscular tone.
  • This preliminary test is carried out by the individual in a natural position and barefoot- on a flat surface which corresponds to a favourable situation with a good muscular tone. Then the test is repeated with an obstacle placed under a foot so as to place the body in an extremely unfavourable situation which then corresponds to a poor muscular tone.
  • each wedge or pair of wedges is tested once, by means of a series of at least 10 tests.
  • the user or individual thus exerts the greatest force they can, as fast as they can, 10 successive times, with a time interval between each test to enable the tests to be distinguished by the data acquisition unit.
  • On each pressure the force exerted and the time taken to exert it are recorded.
  • the user is asked to press using an approximately identical force on the sensor for each of these 10 tests and measurements are carried out.
  • the data acquisition unit calculates a value of F 2 /t for each test, discards the two highest and two lowest values, and then calculates an average of the 6 remaining results. The average value is therefore the output parameter for each wedge or pair of wedges tested.
  • this particular testing method is a non-restrictive example, but it remains a good compromise between the result obtained and the time required for implementing the method so as to carry out the operation in times compatible with commercial requirements, such as when hiring skis.
  • the weakest force exerted and the shortest time to do so reflect the best muscular tone and thus indicate the best alignment and thus the best-adapted set of wedges.
  • the force exerted in each test can be very similar, in which case good postural alignment may be assessed by recording the force (pressure) vs. time curve and measuring the slope so as to determine this fast reaction speed synonymous with good muscular tone. This corresponds to well-being and thus to correct alignment since it is the only parameter which varies significantly during testing.
  • recorded values of the output parameter can be converted into a graph permitting immediate interpretation without the need to read the values. This is advantageous because the values are relative values whose primary purpose is to allow comparisons to between tests to be made.
  • a symbolic or a luminous display for example of the type red/incorrect; green/correct.
  • extremely quick inflation of the bladder is required to analyse the reaction of the individual who has the bladder closed in his hand and who is instructed to keep the hand closed and resist the inflation force.
  • This analysis fully conforms to the prescriptions of kinesiology.
  • This inflatable bladder can be replaced by a pneumatic thruster whose response times can be extremely short if it is fed by suitable pressurised gas source.
  • a static sensor 12-1 for measuring the force applied, with its link 14-1 as shown in figure 1 , as opposed to the dynamic sensor 12.
  • the sensor 12-1 continuously records in the same way the value of the force exerted but without any significant movement of the individual's thumb while the sensor is held in the hand.
  • the advantage is to stop the resisting effort of the return element which facilitates manufacture. Only the force/pressure gauge within the sensor is stressed.
  • the device shown in figure 1 may also be made extremely small and in this case, the link is internal, the sensor and the data acquisition unit being amalgamated into a single housing and being held in the hand.
  • Figure 4 shows a data acquisition block diagram with a summary presentation allowing direct reading of the final information.
  • FIG 4 the block diagram shown in a simplified way illustrates starting with the selection of the number of tests, start-up and verification of the correct connection of the sensor. Then the tests are numbered and recorded to determine the force
  • the method and the sensor described as embodiments are for aligning the support of an individual and this advantageously includes alignment of the whole body. This may involve correction means other than wedges, such as existing devices for correcting the maxillary posture.
  • the device of the embodiment may make it possible to determine a state of the person and of his sensations of well-being or otherwise, depending on whether the correction applied to the posture is satisfactory or not.

Abstract

De nombreux individus présentent des défauts d'alignement postural qui peuvent être corrigés par l'utilisation d'accessoires d'alignement tels que des cales à placer sous les pieds. En corrigeant l'alignement postural de cette manière, on peut améliorer les performances sportives. La présente invention concerne un dispositif et un procédé qui permettent de choisir entre des accessoires d'alignement postural de formes différentes afin d'optimiser l'alignement postural. Le dispositif de l'invention comprend un capteur (12) muni d'un piston (22) qui peut être enfoncé par un individu. Une unité d'acquisition de données (10) enregistre la force appliquée par l'individu et le temps nécessaire à l'application de cette force. Pour chacun des différents accessoires d'alignement postural, l'individu doit enfoncer le piston avec la plus grande force possible (F) pendant une durée aussi courte que possible (t). L'unité d'acquisition des données produit un paramètre de sortie basé, de préférence, sur F2/t or F/t. L'accessoire d'alignement postural optimal est celui qui correspond au paramètre de sortie le plus élevé.
