Patient management device, system and method

A portable apparatus to manage a plurality of events related to a patient and to record and store input data related to said events, said portable apparatus comprising:

• a user interface comprising an input unit configured to register patient input data elements and an output unit configured to provide information elements to said patient;
• a timer unit arranged to trigger at least a first event of said plurality of events and to tag said input data with a time stamp;
• a control unit, arranged to provide an invitation as an instruction via said output unit to said patient to perform a desired movement in a motion exercise, upon said trigger from said timer unit or upon a patient self-initiation;
• at least one sensor unit arranged to record measurement data elements related to said motion exercise of said patient, wherein said at least one sensor unit comprises at least one accelerometer adapted to measure a motion of said portable apparatus;
• and a storage unit, arranged to retrievably store said input data comprising said patient input data elements and said measurement data elements, when recorded by said input unit and/or said sensor unit, together with said time stamp, and wherein said storage unit is adapted to store said measurement data elements from said motion exercise performed upon said instruction or upon said patient self-initiation of said motion exercise wherein:
• said input unit is responsive to said invitation provided to said patient by said output unit and upon triggering said event, or to a patient self-initiation;
• said portable apparatus is adapted to be held by said patient, or attached in a fixed relation to a body portion of said patient, and thus to serve as a mass to be moved in a desired manner by said patient during said motion exercise in such a manner that said measurement data elements are provided that are related to a movement of said portable apparatus in at least two dimensions by said patient during said motion exercise;
• and said control unit is a unit configured to correlate said instructions to said measurement data elements and to analyze said measurement data elements to determine a degree of a chronic disease, wherein said analyzing unit is adapted to calculate a speed, direction of movement, distance, time and force that acts upon the device from said measurement data elements and said time stamp stored together, as provided by said movement and said mass of said portable apparatus, and whereby said control unit is adapted to provide a determination that said movement of said motion exercise has been correctly performed.
