“System Configured to monitor the motor activity of a person’s lower limbs and method thereof”

The present invention relates to a system con figured to monitor the motor activity of a person’s lower limbs. [0002] Particularly, the present invention relates to a wearable system configured to calculate at least one in dex and compare said at least one index with one or more predetermined threshold values for monitoring the motor activity of the lower limbs of a person, in particular a per son with Parkinson’s disease. [0003] More particularly, by means of the system, ob ject of the invention, it is possible to determine if said person walks with a regular gait or walks with an irregular gait or does not walk. [0004] The expression "regular gait" refers to a walk in which the width of the step, the duration of the step and the frequency of the step of each leg are constant or substantially constant values during the walk and equal or substantially equal for the two legs. [0005] The expression "irregular gait" refers to a walk in which the width of the step and/or the duration of the step and/or the frequency of the step of each leg are not constant or substantially constant values during the walk and/or to a walk with sudden and temporary interruptions. [0006] If the person is a person with Parkinson’s dis ease, this person can walk irregularly when subjected to a Freezing of Gait (FOG) event. [0007] The event of Freezing of Gait may consist of an involuntary, sudden and temporary motor block, which can cause the person to fall. [0008] For the sake of brevity the expression "Freezing event" will be used below to indicate a Freezing of Gait event
