System and method for self-assessment of physical capabilities and condition changes

A method for self-assessment of physical capabilities and changes in a physical condition of a person, in a system, the method comprising:

• providing an inertial motion sensor tightly attached to the person's body for measuring a body movement;
• carrying out at least one test of self assessment of motor capabilities, said test selected from a group consisting of a body balance, a muscle strength, a muscle spasticity and a hand dexterity and collecting data;
• sending collected data to a processing software executed in a mobile device or a remote server;
• determining the change in said physical condition if at least one of the following measured parameters have changed between two consecutive measurements as follows:
• balance is worsening if postural sway amplitude has increased;
• muscle strength is decreasing if range of motion test motion amplitude has decreased or range of motion test speed has decreased or jumping height has decreased;
• spasticity is increasing if spasticity test motion range is decreased;
• and parameters are improved if opposite changes have occurred, and
• video recording of the performed test and wherein said software is configured to synchronize said video recording and said signal from motion sensor by activating a light indicator on the motion sensor, and simultaneously adding a specific signature at said signal from motion sensor.
