    Abstract: The present disclosure describes systems, devices, and methods for determining stability of a joint of a living subject. In one aspect, a force-measuring device for determining stability of a joint of a living subject is provided. In some examples, the force-measuring device includes a mitt frame configured to receive a hand of a user therein, one or more first force sensors, and one or more second force sensors. The mitt frame may include a palm portion configured to receive a palm of the user therein, and a finger portion configured to receive fingers of the user therein. The one or more first force sensors may be coupled to the palm portion and disposed on an exterior surface of the palm portion. The one or more second force sensors may be coupled to the finger portion and disposed on an exterior surface of the finger portion.

    Abstract: The subject of the invention is a method for monitoring, analysing and correcting the position of the head, which enables precise monitoring of the movement of the cervical spine, head and shoulders, as well as the detection of posture defects, where the device for monitoring, analyzing and correcting the head position, which is also the subject of the present invention, can be used for correcting them. In order to effectively achieve the intended object of the invention, the control points from which the data on the user's body deviation in three dimensions (X, Y and Z) are read have been properly defined. The following items are placed in these points: - always on both sides in the front part of the user's neck - sensors (1), - and possibly additionally on the user's chin - a sensor (detector) (2), - on user's vertebra C2 - a sensor (detector) (2), - on the user's forehead - a sensor (detector) (2), - on each mastoid process, at the bottom of the ear, on both sides of the user's head - a sensor (detector) (2), Whereas, a stable - usually two-layer - helmet (3) with a variable mass centre is placed on the user's head, the top layer of which may consist of electromagnetic coils. The information read from the recorders is sent, collected and processed in a server cooperating with "Machine Learning" software, using it to develop information about remedial and corrective exercises, which is fed back to sensors (detectors) (2), the helmet (3) and its electromagnetic coils and is controlled by them. Usually, an electromagnetic field begins to be emitted, which attracts a changing mass centre under the influence of the electromagnetic field to the place designated by the server. Correcting or changing the user's posture can be carried out owing to the images emitted in the mask (5) with a display in the front part of the helmet (3) or in the glasses (6) worn by the user.
