Abstract

A portable apparatus for managing a plurality of events related to a patient and for recording and storing input data related to said events is disclosed. The portable apparatus comprises a man machine user interface; a timer unit; a control unit, arranged to provide an invitation to the patient as an instruction via the interface to perform a motion exercise, upon a trigger from the timer unit or upon a patient self initiation. In an embodiment the apparatus comprises a sensor to record measurements related to said motion exercise. Further, a storage unit is arranged to retrievably store patient input data and said measurements. This enables diagnosing a degree of a neurological disease or an effect of a medication on said neurological disease.

Claims

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 means of 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 for analyzing said measurement data elements, 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.
