- the first shoulder angle E 1 is easily obtained:
- the second shoulder angle E2 can thus be obtained indirectly, via two vector products:
- the third shoulder angle E3 corresponds to the angle between two vectors where
- the third shoulder angle E3 is then expressed as:
- the same methodology can be used to calculate the angles of the elbow and wrist.
- the orientation of the sensor 3 with respect to the sensor 2 will give the two angles of the elbow.

- the frequency of calculation of angles and performing update values for the Avatar is in the order of 100 Hz.
- the ability to display in real time, via an avatar, the movements made by the technician is a great advantage, including providing a direct view of the actions performed.
- the recording of data at a frequency of the order of 25 Hz allows a fluid movement during a video reconstitution of the technician's performance, for statistical analysis and interpretation purposes, for example.
- visual and / or audible warning means are triggered when at least one of the angles of the joints exceed a certain angular degree, c that is to say out of a range of predetermined comfort values, said values being configurable.
- the active orthosis system may also comprise means for generating vibrations directly on the body part, so as to alert the operator by these vibrations.
- comfort zones in terms of gestures and postures are known and help preserve physiological health. If the degree of angulation of the joints induced movement exceeds the level of the comfort zone, the movement is considered to be detrimental to the joint. As soon as the angle of articulation exceeds the angle of the comfort zone, the warning system is triggered. The operator carrying the active orthosis is therefore prompted to correct posture, correct his actions, so as to bring all the angles in the comfort zone, that is to say in the range of predetermined values considered safe from the physiological point of view.
- alerting means For a visual perception of the triggering of the alert, light-emitting diodes can be installed on the system active orthosis. In addition, indicator lights or specific messages may be displayed on the computer screen. For example, when the hand bends too much, the hand of the avatar may be displayed in red.
- the emission of a sound signal or a specific voice message For example, according to a particular embodiment, the installation of piezoelectric buzzers is provided.
- a tactile perception of the triggering of the alert can also be implemented, according to another embodiment, through means capable of generating vibrations, installed on the active orthosis in contact with the body.
- the various warning means used are adapted to give the operator guidance to bring it, if necessary, to correct his posture so as to maintain each of the angles adopted by his joints in ranges predetermined comfort values.
- the results of measurements and calculations of angles of the joints can be the subject of a statistical analysis to monitor the progress and performance of the operator. After an intervention, it is for example possible to replay, offline, on the computer screen displaying the avatar, a video representing the actions performed by the operator and the triggering of any alerts. Thus, the operator is able to perfect his practice.
- the present invention provides the exploitation of the data from the angle measurements on at least two joints of an individual.
- MSDs consisting solely in training users to individually maintain each of the joints requested for a task, in a so-called "comfort" angle, so that said task is the least traumatic possible for anatomical structures articular and peri-articular (mainly the tendon that holds the muscle by insertion on the bone), may be non-optimal.
- this "univalent" approach to the cause of periarticular lesions does not take into account the muscular synergy that occurs on nearby joints when performing a movement. For example, if prevention merely maintains the elbow joint in the "comfort" angle zone when the forearm flexes on the arm, which primarily involves the biceps, it will not take into account the contraction of the muscle deltoid. This, although the shoulder joint may be in a "comfort” angle, will act on the periarticular elements of the rotator cuff, and, when this movement is repeated at the elbow, lesions may appear on the shoulder.
- the prevention of periarticular affections aims, globally, all the joints of a limb, or at least the joint or the joints close to that which make a movement.
- the present invention also relates to a method advantageously based on the use of an active orthosis system as described above and a calculator.
- a posture is recommended to a technician, said recommended stance for a member of said technician, for example an upper limb, based on measurements of angles of at least two joints of said limb, said measurements being made by means of said system active orthosis.
- said calculator determines, from measured values, thanks to the active orthosis, angles formed by at least two joints of a member of the user, typically the shoulder and the elbow, the optimal position of the patient. entire arm to limit the risk of injury while performing the gesture desired by the user.
- the invention thus relates to a method for determining an optimum between the angles of at least two joints of a limb to minimize the risk of TMS, as a function of angles of said at least two joints measured by means of the orthosis. active previously described.
- the active orthosis system according to the invention is particularly applicable in many technical fields, and can not be limited to the field of the gesture made by animal insemination technicians.
