    Indicator
    Field of the Invention
    The present invention relates to the area of analysis of joint motion and in particular to the area of analysis of foot movement relative to adjacent bodily structures or to the foot deformation as a consequence of load.
    Background of the Invention
    The area of analysis of the foot position and the foot alignment and the foot movement during walking or running has long been a focus area for therapists in the area.
    Objective of the Invention
    In the physiological analysis and treatment of various conditions related to the position of various parts of the foot, it is relevant and necessary to perform a qualitative or quantitative measurement of the actual scope of the condition.
    In relation to more common daily routines as selecting the right footwear for a specific type of foot alignment during for example running it is likewise relevant to make a qualitative or quantitative analysis of the actual condition in order to ensure the right choice or recommendation regarding footwear.
    Previously it has been a normal procedure to provide an indication by making a marking, e.g. a line, on a person’s foot and lower leg and following this during movement, either entirely visually by eye or by video recording, eventually assisted by kinematic or kinetic systems. This has worked to some extent, but a significant uncertainty is connected with this measurement and hence a need for improvement is present.
    The objective of the present invention is to provide an improved indicator that will enable an easier and more reliable analysis of the foot motion.
    Description of the Invention
    According to the invention the objective is achieved through a position indicator for measuring position of a foot or relative position of part of a foot, the indicator comprising an elongate element with a proximal end and a distal end, where in connection with the distal end means for attaching the elongate element to a foot part are provided and where the elongate element is adapted to be freely movable at its proximal end.
    In an embodiment the distal end of the elongate element has an increased width compared with the rest of the elongate element.
    The means for attaching the distal end of the elongate element to the foot may comprise an adhesive, where the adhesive may be applied directly onto the elongate element or on an adhesive bandage applied on top of the elongate element's distal end.
    In an embodiment a measurement scale is provided, the measurement scale being provided to estimate the movement of the elongate element, where the measurement scale is adapted to measure an angular movement of the elongate element and/or a longitudinal movement of the elongate element and/or a rotational movement of the elongate element.
    Such scale may show the movement of the elongate element as an absolute measurement in either distance or in angular pivoting or in rotation or as an interval of movement, e.g. indicated with colours showing a range of displacement in either distance or angular pivoting.
    The measurement scale may be adapted to be fixed onto the skin, e.g. through an adhesive applied on the measurement scale. Hereby the scale will follow the movement of the leg above the fixation of the indicator at the distal end of the elongate element.
    The elongate element may be manufactured from at least two materials with different degrees of flexibility and mutually connected, e.g. through a moulding process including adhesive attachment.
    In a further embodiment one or more reflective or otherwise identifiable markers are attached to the indicator. Hereby the use of the indicator may be further included in motion analysis e.g. in connection with video recordings, where also markers on other body parts may be included.
    As an option the attachment means are of a type allowing only single use. This will increase the sanitary conditions related to use.
    The invention is described in more detail with reference to the attached drawing, where:
    Description of the Drawing FIG. 1 shows a first embodiment of an indicator according to the invention; FIG. 2 shows a second embodiment of an indicator according to the invention; FIG. 3 shows a foot seen from the side with an indicator mounted; FIG. 4 shows a foot seen from behind with an indicator mounted: FIG. 5 shows a foot seen from the side with an indicator mounted in a second position; FIG. 6 shows a foot seen from behind with an indicator mounted in a second position. FIG. 7 shows a pair of feet seen from behind, where the feet are neutral; FIG. 8 shows a pair of feet seen from behind, where the feet deviate from neutral position; and FIG. 9 shows a pair of feet seen from behind, where the feet deviate from neutral position.
    Detailed Description of the Invention
    From FIG. 1 a first embodiment of the indicator appears. The indicator comprises a elongate element having a proximal end and a distal end. At the distal end a fastening element is provided for fastening the indicator to the skin of the patient's foot.
    From FIG. 2 second embodiment of the indicator appears. The embodiment comprises the same elements as described in connection with the first embodiment and in addition to these elements one or more measurement scales are provided to facilitate a more detailed measurement of the elongate element in relation to angular and/or longitudinal and/or rotational movements of this.
    From FIG. 3 the indicator according to the first embodiment is seen in a position where this is mounted on the heel of a patient in a first and a second position and seen in a side view.
    From FIG. 4 the indicator according to the first embodiment is seen in a position where this is mounted on the heel of a patient in a first and a second position and seen in a rear view.
    From FIG. 5 the indicator according to the first embodiment is seen in a position where this is mounted on the side of a patient's foot in a first and a second position and seen in a side view.
    From FIG. 6 the indicator according to the first embodiment is seen in a position where this is mounted on the side of a patient's foot in a first and a second position and seen in a rear view.
    For explanatory reasons FIGS. 7, 8 and 9 are included to demonstrate different variations of the foot inclination from neutral position. FIG. 7 shows the neutral position of the feet, whereas FIGS. 8 and 9 shows a first and a second type of deviation from the neutral position, where the indicator according to the invention may more accurately help determine the degree of deviance from the neutral position.
    Observation method
    When attaching the indicator it is of significant importance for the measurement result that this is done at the correct location of the foot.
    The following is describing a method for measuring the inclination and/or longi-tudenal and/or rotational movements of Os Calcaneus in the frontal plane and the position of Os Naviculare over a substrate.
    Visual observation of the hind foot:
    From Posterior i.e. with visual direction from behind and towards the person.
    With the direction exactly levelled with height of the Achilles tendon (Tendo Calce-neo/Tendo Achillis) attachment to the heel bone (Os Calcaeneus).
    With visual direction directly along the extension of the foot centerline - independent of the foot rotation in the horizontal plane in the Mid-Stand-Phase - where the lateral malleolus is vertically below Trochanter Major.
    To do prior to visual observation:
    The height of Tendo Achillis attachment to Os Calceneus relative to the substrate is measured and registered.
    Posterior camera is adjusted in this height.
    Direction of the foot center line in the horizontal plane - equal to the direction of a straight line from the heel center line to the separation between the 2. and 3. toe. Posterior camera is adjusted in the extension and straight direction of this line.
    Os Calceneus' sagittal center line seen in posterior view.
    The observer positions himself behind the patient centrally and above the extension of the foot center line in the horizontal plane.
    With left and right thumbs Os Calceneus is medially and laterally palpated as distally as possible with opposite directed and equal pressures through the skin. A point is marked as distal as possible on Os Calceneus on the sagittal center line.
    With left and right thumbs Os Calceneus is medially and laterally palpated as proxi-mally as possible with opposite directed and equal pressures through the skin. A point is marked as proximal as possible on Os Calceneus on the sagittal mid line. A line is marked between the proximal and the distal points - representing the Os Calceneus' sagittal mid line.
    The indicator is applied on the skin on the Os Calceneus' sagittal center line.
    Os Calceneus' inclination in corrected hind foot position:
    The patient is standing upright with straight knees and looking forward.
    The observer places himself sitting or kneeling centrally in front of the patient.
    The observer grips the patient's right knee cap with his left hand and with the right hand the left knee cap.
    The observer helps the patient by use of hands and verbal instruction to rotate both patient's legs outwards in the hip joints - with extended knees.
    The observer helps the patient by use of hands and verbal instruction to rotate both patient's legs inwards in the hip joints - with extended knees.
    The patient repeats these movements, with help from the observer until possible to do these movements on his/her own.
    The observer palpates with thumb and index finger the Os Talus necks on the patients feet while the patients conducts slow outwards and inwards rotations according to the observer's verbal instructions.
    The observer palpates Os Talus neck, while it shifts medially and laterally.
    The observer instructs the patient to maintain the specific rotation of his/her legs until the Os Talus neck is palpated equally medially and laterally.
    The observer observes and measures with an angular measurement the inclination of Os Calcaneus' sagittal center line with the patient's hind foot in this position.
    The measured inclination of Os Calceneus' sagittal center line is registered as the rear foot corrected angle.
    The corrected angle is expressed in Varus (- degrees), Neutral (0 degrees) or Valgus (+ degrees).
    Os Calceneus' inclination in uncorrected hind foot position:
    The patient relaxes from the instructed rotation of his/her legs and lets the foot rest in its uncorrected position.
    The observer observes and measures the inclination of Os Calceneus' sagittal center line with the patient's hind foot in this position.
    The hereby measured inclination of Os Calceneus' sagittal center line is registered as the hind foot uncorrected angle.
    The uncorrected angle is expressed in Varus (- degrees), Neutral (0 degrees) or Valgus (+ degrees).
    Os Naviculare's height over the substrate in corrected hind foot position:
    The observer instructs the patient to position and maintain the specific rotation of the legs where Os Talus necks are equally prominent when palpated medially and laterally.
    The observer observes and measures with a height measurer the height of Os Navicu-lare over the substrate with the patient's hind foot in this position.
    The hereby measured height is registered as the Os Naviculare's corrected height.
    The Os Naviculare's corrected height is expressed in mm.
    Os Naviculare's height over the substrate in uncorrected hind foot position:
    The patient relaxes from the instructed rotation of his/her legs and lets the foot rest in its uncorrected position.
    The observer observes and measures with a height measurer the height of Os Navicu-lare over the substrate with the patient's hind foot in this position.
    The hereby measured height is registered as the Os Naviculare's uncorrected height. The Os Naviculare's uncorrected height is expressed in mm.
    Indicator is applicated on the skin on the Os Naviculare's prominence.
    Kinematic and/or kinetic recordings and analysis may now be performed, with or without footwear.
