Definitions
- the present invention relates to the field of measurement, monitoring, control and correction of a movement or posture performed by a user (human or animal),
- the term “movement” refers to the displacement of a body relative to a reference frame of space and at a given moment, this displacement being able to be zero (immobile body) or non-zero (body mobile).
- the present invention relates to a method and system for the evaluation, monitoring, correction, rehabilitation and training of proprioceptive and / or postural and / or locomotor and / or motor and / or orientation capabilities. space of a user.
- the term "movement” refers to the movement of a point (or set of points), of one (or more) segment (s) of the user's body (s). (Trunk, femur, foot, tibia / fibula, hip, arm, forearm, etc.) in space over time, this displacement can be zero (still) or non-zero (moving point).
- such a movement can be defined by a succession of positions in space taken over time, and by a series of speeds of movement between two successive positions of the sequence of positions.
- a movement is represented by a set of vectors (for example “velocity vector” or “orientation vector”) which each define the displacement of a point with respect to a fixed repository of space and at a given instant .
- vectors for example "velocity vector” or "orientation vector”
- the invention advantageously has many applications, especially in the specialties associated with rehabilitation:
- the present invention makes it possible to assist a user by correcting his movements in order to:
- WO 2008/132324 discloses a device for measuring and correcting the postural vertical of a human being. This device consists of a camera, a display screen and processing means. The operating principle of such a device is as follows:
- the camera is installed behind the user so as to acquire images of his back
- the display screen is installed in front of the user so that he can observe the images displayed on said screen
- the processing means are connected to the camera and the display screen.
- the camera is activated to acquire images of the user's back. These images are transmitted to the processing means for estimating an inclination of the patient's back relative to the vertical.
- the processing means then control the display on the display screen:
- Such a device has many disadvantages. On the one hand, the installation of the device as a whole is laborious and can not be implemented by the user himself. Indeed, the installation of markers in the back of the user and the positioning of the camera requires the presence of a person to assist the user.
- Another disadvantage of this device is that the information displayed on the display screen is not intuitive enough to enable it to properly correct his posture.
- the observation of its inclination relative to the vertical may encourage the user to force his muscles excessively to align his back on the vertical.
- studies have shown that the level of difficulty of rehabilitation exercises should be progressive and that excessive re-education could have harmful consequences. For example knee flexion exercises at too large an angle after cruciate ligament surgery can induce irreversible degradation of ligament properties.
- Another disadvantage of this device is that the information displayed on the screen does not allow the user to understand his progress during his rehabilitation. Indeed, even if the display of a deviation angle value is relevant information for a treating physician, it is not for a neophyte user.
- US 201 1/0021318 describes a device for driving the motor control of a user.
- US 7,867,140 discloses a device for correcting the motor coordination of a user. These devices have the same disadvantages as the device described in WO 2008/132324.

- FIG. 1 schematically illustrates an exemplary method for controlling, correcting and evaluating the postural, locomotor or motor abilities of a user
- FIG. 2 illustrates an example of use of a mobile terminal programmed to implement the method illustrated in FIG. 1.
- the method according to the invention is dedicated to the evaluation, monitoring and rehabilitation of proprioceptive and / or postural and / or locomotor and / or motor and / or spatial orientation abilities of a user. It can be implemented in the form of a downloadable application that can be implemented in a mobile terminal 1, including:

- the mobile terminal 1 also includes storage means such as a memory for storing predefined exercises for re-educating the user.
- the various means for the implementation of the method are embedded in a single device such as a mobile terminal 1 facilitates the implementation of the method for the user. Indeed, the only operation to be performed for the user is to fix the mobile terminal 1 on him, for example using a belt including a case for receiving the mobile terminal 1.
- the mobile terminal 1 is for example a mobile phone including Smartphone type, a personal assistant (or "PDA", acronym of the English expression “Personal Digital Assistant”), or any type of mobile terminal known to man of the trade, such as an iWatch® connected watch.
- PDA personal assistant
- iWatch® connected watch any type of mobile terminal known to man of the trade, such as an iWatch® connected watch.
- the mobile terminal can be fixed on a mobile platform on which the user is standing while trying to be stationary; the terminal then measures the movement of the platform: the less the platform oscillates, the better the user's performance.
- the mobile terminal may be attached to a region of the user.
- the region in which the mobile terminal is attached depends on the body segment, or more broadly the ability to re-educate.
- the mobile terminal will be fixed on the chest of the user.
- the mobile terminal will be attached to the forearm of the user, etc.
- the region in which the mobile terminal is fixed may vary according to the exercise performed.
- the mobile terminal in the case of a rehabilitation of sensorimotor and functional knee capabilities, the mobile terminal can be fixed:
- a first phase of the method may consist in informing the user of a mode of operation helping him to set up the terminal and to select an exercise.
- This information phase may for example consist of editing a visual and / or auditory tutorial to the user.
- a visual and / or auditory description of the exercise to be performed can be provided to the user.
- the mobile terminal 1 executes different phases:
- the method comprises measuring by sensors of the mobile terminal 1, a plurality of groups of values.
- Each value of a group comes from a respective sensor.
- a mobile terminal including a 3D accelerometer, a 3D magnetometer and a 3D gyroscope:
- three values correspond to magnetic fields along the same three orthogonal axes.
- the present invention is not limited to the use of 3D accelerometer, 3D magnetometer and 3D gyroscope, but concerns the use of any type of accelerometer, magnetometer and gyroscope (1 D, 2D in particular).
- the method may also include an optional step of filtering the groups of values measured from the sensors of the mobile terminal. This eliminates disturbances due to noise and measurement errors.
- the filtering of groups of values can be implemented using a Kalman filter.
- This type of filter is particularly suitable for estimating parameters of a system evolving over time from noisy measurements, which is the case in the context of the present invention since the different groups of values are representative signals of a movement made by the user.
- each group of values carries information on:
- the method comprises determining one (or more) data (s) estimated from each group of values.
- the processor of the mobile terminal processes the groups of values to extract the information relating to the position, and / or the orientation and / or the speed and / or the acceleration of displacement of the mobile terminal at different times of measurement. the period of time.
- a series of estimated data is thus obtained at different times of the time period, this sequence being representative of the actual movement of the user during the period of time.
- this sequence being representative of the actual movement of the user during the period of time.
- only certain parameters of the movement performed by the user may require control. For example, for some exercises, the speed of movement of the body segment is not a determining factor of rehabilitation. In this case, no estimated velocity data will be determined from the groups of values. This limits:
- the estimated data suite is compared to theoretical data. These theoretical data are representative of a desired movement that the user should realize during the execution of the exercise.
- the comparison step makes it possible to obtain a plurality of correspondence gaps.
- the differences are not necessarily related to an inability of the user to correctly perform the "ideal" movement, but may be due to the fact that the user has difficulty in assessing some constraints difficult to quantify his movement such as the speed of movement .
- the invention proposes to provide him with an indication enabling him to correct his actual movement so as to best match it to the "ideal" movement.
- the biological feedback can consist in the emission of stimuli of different types depending on the nature of the error to be corrected (in the movement made by the patient) and / or according to the preferences or capabilities of its user: by For example, a hard-of-hearing user may choose visual and / or tactile stimulus (stimuli).
- the feedback can consist of the emission of an auditory stimulus
- the feedback will consist of the emission of an auditory stimulus (if the angulation is too weak) or tactile (if the angulation is too great) .
- more or less rapid successions (or more or fewer) of stimuli of the same nature can be used to indicate to the user that a parameter of his movement is incorrect.
- a rapid (respectively slow) succession of auditory stimuli may be used to indicate a slow (or too fast) rate of movement of the forearm (or vice versa).
- the method includes calculating a score associated with the execution of the exercise by the user.
- the calculation of this score has many advantages. Indeed, it allows the user to evaluate his progress in the execution of the exercises, and thus the benefits of his rehabilitation.
- the method includes a step 70 of transmitting the score (s)
- the calculation of the score allows a third party to monitor the progress of the user in his rehabilitation.
- Proprioceptive Capacity Rehabilitation is for a mobile application dedicated to the evaluation, monitoring and rehabilitation of a user's proprioceptive capabilities. It consists of an integrated solution of angulation measurements of at least one joint or at least one body segment (eg, ankle, knee, hip, spine, wrist, arm, shoulder, neck) during predefined exercises.
- This application allows both the measurement and improvement of proprioceptive capabilities through visual and / or auditory and / or tactile (eg vibratory) biological feedback.
- the communicating nature of the mobile terminal can be used to transmit the results obtained to the third parties concerned (doctor, physiotherapist, etc.).
- the application makes it possible to quantify the movements of the articulation based on measurements taken from the sensors embedded in the mobile terminal, and in particular:
- a 3D magnetometer for measuring magnetic fields along the same three orthogonal axes.
- the app is designed to be used independently and includes pre-programmed workout exercises. Part of these exercises is dedicated to rehabilitation and is based on the principle of perceptual substitution. To do this, an auditory or vibratory feedback has been programmed to alert the user of an excessive inclination with respect to the expected state and to induce him to reposition himself correctly.
- One of the original features of this exemplary embodiment relies on the integration of the information from the gyroscope and the magnetometer which makes it possible to improve the quality in the estimation of the movement carried out by the user.
- Another originality of this exemplary embodiment is based on the design of a mobile application dedicated to the evaluation and rehabilitation with a mobile terminal as sole support.
- a smartphone including three types of tri-axis sensors: an accelerometer, a magnetometer and a gyroscope.
- the measurements obtained are subject to the biases specific to each of these three types of sensors (noise, magnetic disturbance, drift due to integration).
- the angles of inclination ( ⁇ , ⁇ ) are estimated from measurements from the accelerometer.
- the direction ( ⁇ ) is estimated from the measurements from the magnetometer. This gives a first estimate of the orientation vector ( ⁇ , ⁇ , ⁇ ).
- the different disturbances of the gyro measurements are corrected by comparing the two estimates obtained for the orientation vector.
- the difference (c diff, Gdiff, ijJdiff) between the first and second orientation vectors estimated is then used to update the coefficients of the Kalman filter that will be applied to the next iteration.
- the fusion of the data from the different sensors provides an estimation of the angles of rotation ((p es t, ⁇ ⁇ 8 ⁇ , ⁇ 8 representing the angulation of the mobile terminal relative to its average position on the "n" (for example five ) first seconds of the test (reference ( ⁇ , ⁇ , ⁇ )) - Perceptual substitution and biofeedback
- the application offers, in addition to the evaluation, rehabilitation exercises based on the implementation and use of sensory biological feedback.
- the biological feedback can consist in the emission of stimuli whose type (for example, sensory, auditory, tactile) can vary according to the sensitivity, the capacities and / or the preferences of the user. For example, visual stimuli for blind or visually impaired patients, etc., will be avoided.
- the biological feedback can consist of the combination of different types of stimuli: for example visual / audio and audio / tactile etc.
- biological feedback can be:
- the user has a continuous feedback of the current positions of his articulation, or
- the user receives information relating to the deviation (or the error in direction and / or amplitude) between the current position of its articulation and that which should be obtained with regard to the proposed exercise. In other words, if there is no error, there is no sensory feedback.
- a level of tolerance called "white zone” 2, parameterizable is proposed in order to adapt the level of difficulty to the motor skills of the user and its progression, in particular.
- At least two variants of biological feedback control can for example be proposed:
- a first variant in which the user is instructed to mobilize his trunk towards the vibration; for example, if the spine is on the left with respect to a white zone (position referenced 5 in FIG. 2), the right vibrator is activated; the user moves his trunk to the right; the vibration stops when the inclination of the trunk is again inside the white zone 2 (for example positions referenced 3 and 4 in FIG.
- the advantage of the invention is to have an all-in-one device, combining measurement, analysis, storage, correction, sensory feedback and adaptation.
- This device because of its communicating nature, makes it possible to trace information very quickly to a third party (for example a medical team), to verify the results and exercises performed, and ultimately, to adapt the proposed sessions to the 'user.
- Another feature of the invention lies in the secure transmission of the measured and analyzed data and in their comparison to a database.
- the following example is for a mobile application dedicated to the evaluation, monitoring, training and rehabilitation of posture control, balance and walking skills.
- This application consists of an integrated solution of measurements and feedback of positions and / or speeds and / or accelerations and / or orientations of one or more body segments (for example the angulation of the trunk with respect to the vertical) in tasks postural, motor and locomotive that the user can advantageously achieve in his place of life (and not only in a medical office or paramedical).
- this solution can also incorporate relevant complementary measures (such as kinematic measurements and / or kinetic measurements and / or physiological measurements) via wired or wireless sensors connected to the mobile terminal (such as sensors). heart rate and / or respiration and / or pressure and / or oculometry and / or electromyography and / or GPS location, etc.).
- relevant complementary measures such as kinematic measurements and / or kinetic measurements and / or physiological measurements
- the mobile terminal such as sensors.
- Assessment tasks and / or training or rehabilitation exercises may for example consist of standing as still as possible under different postural conditions (eg on different types of stable or unstable supports, and / or in different environments sensory).
- Other conditions can be implemented through wireless actuators connected to the mobile terminal (eg, fatigue effect or vibrator disturbance, changing visual conditions with augmented reality connected glasses such as Google Glasses). (or "Google glasses ®” according to the English terminology), movements induced by a platform).
- biological feedback type For example, biological feedback type
- This biological feedback can, for example, be triggered in real time as soon as a situation of postural instability is established, with reference to a predefined model or to the user's capacities determined during a learning phase.
- trunk movements can for example be triggered from the measurements of trunk movements to alert the user of too much inclination of his bust from its initial state and encourage him to reposition correctly.
- a biological feedback is activated as soon as the actual movement of the user differs from the theoretical movement (or a reference value such as a maximum inclination not to be exceeded, or a maximum speed, etc.),
- a biological feedback is activated when the actual movement of the user differs from the theoretical movement to a tolerance margin (predefined thresholds).
- the difficulty of each exercise is configurable to take into account the capabilities of the user.
- the level of difficulty can be updated (especially increased) to keep progress of the user during his rehabilitation.
- One of the original features of the present invention is based on the design of a mobile application dedicated to evaluation and rehabilitation with a mobile terminal as sole support.
- Actuators can be connected to vary the conditions of use and be activated directly from the mobile terminal depending on the exercise and the degree of difficulty sought.
- additional tools may depend on and be modulated by the responsiveness of the subject to the different stimulations relative to the data captured by the mobile terminal.
- additional sensors provides access to additional information that when merged becomes high-level information.
- the proposal of exercises and the modulation of their degree of difficulty are generated automatically by the mobile terminal according to the current state of the user and its progression.
- the communicating nature of the mobile terminal can be used to transmit results obtained to third parties concerned (doctor, physiotherapist, coach, social networks, etc.).
- the mobile terminal used in the example described below is a smartphone including three types of tri-axis sensors: an accelerometer, a magnetometer and a gyroscope.
- the measurements obtained are subject to the biases specific to each of these types of sensor (eg noise, magnetic disturbance, drift due to integration). These measurements are used in a complementary way with a Kalman filter to correct the gyroscope biases and reliably estimate the orientation of the support on which the user stands (for example, unstable platform or Freeman plateau) and / or a body segment of the user (for example, the bust or the lower or upper limb).

- the filter used is an extended Kalman filter.
- the fusion of the data from the various sensors provides an estimation of the angles of rotation representing the angulation of the smartphone relative to its average position on the "n" first seconds of the test ("n" being a natural integer greater than or equal to zero ).
- the application offers in addition to the evaluation of proprioceptive abilities, posture control, balance and locomotion, rehabilitation exercises based on the use of visual and / or auditory biological feedback and / or touch.
- a sensory signal is sent to the corresponding actuator on the offending side.
- this sensory signal may be sent to the actuator opposite the offending side, depending on the user's preferences and / or medical prescriptions, etc.
- this signal constitutes additional sensory information on which the user can rest.
- the tolerance level of the "white" zone is an adjustable parameter from the smartphone interface to adapt the level of difficulty to the physical condition of the user (in this case, proprioceptive abilities) and to the progression of this physical condition (and / or medical prescriptions).
