Abstract
The subject invention involves a device and method for treating patients with a movement disorder experiencing a sudden change in regularity of gait or akinesia, and comprising a device that detects the sudden change in regularity of gait or temporary akinesia and automatically issues a cue signal that restarts the movement.
Claims19
A device for treating a human having a movement disorder comprising:
- a sensor for sensing an akinetic episode of said human and
- a receiver,
- said gait sensor transmitting a signal to said receiver only upon detection of the akinetic episode of said human,
- whereby in response to said received signal, said receiver automatically generates a cueing signal to trigger resumption of movement of said human.

A device for emitting a cue upon detecting of change of regularity of gait of a person comprising:
- a sensor for detecting an akinetic episode of the person,
- said sensor including a signal process,
- said signal process sending a signal to a receiver only upon detection of the akinetic episode of the person,
- said receiver, in response to said signal, causing a cue perceptible by the person to be emitted, to thereby aid in the restoration of movement of the person.
1 more element
A method of managing a freezing gait disorder of a person, comprising the steps of:
- sensing a change of regularity of gait of the person,
- transmitting a signal to a receiver only upon sensing the change of regularity of gait,
- automatically generating a cueing signal only upon reception of the signal by said receiver,
- whereby said receiver restarts the gait of said person using single or multiple cues.
