Abstract

Devices used to cue a user to take a step when experiencing a walking disorder, such as a freezing of gait episode, are disclosed. The devices are configured to cue the user with a visual and/or audible cue. The devices include an activation module and a cueing module. The cueing module includes a metronome and a laser light source. The devices are mounted on an assistive mobility device or on the user.

Claims (51)

1 . A device for treatment of a walking disorder, comprising:

an activation module configured to be physically coupled and decoupled to a walking support structure or a waistband of a user at a first location, comprising:

(i) an audible cueing activation switch; and

(ii) a visual cueing activation switch; and

a cueing module configured to be physically coupled and decoupled to the walking support structure or the waistband of the user, comprising:

(i) a source of a visual cue; and

(ii) a metronome.

2 . The device of claim 1 , wherein the activation module is configured to be physically coupled and decoupled to the walking support structure of the user at the first location such that the audible cueing activation switch and the visual cueing activation switch are within reach of a finger of the user.

3 . The device of claim 1 , wherein the cueing module is configured to be physically coupled and decoupled to the walking support structure at a second location that is different than the first location.

4 . The device of claim 1 , wherein the source of the visual cue is a laser light source configured to project a laser light image onto a walking surface.

5 . The device of claim 4 , wherein the laser light source is adjustable relative to the cueing module.

6 . The device of claim 5 , wherein the laser light source is configured to be adjusted to set a desired distance of the projected laser light image.

7 . The device of claim 5 , wherein the laser light source is rotatably adjustable about a longitudinal axis of the cueing module.

8 . The device of claim 1 , wherein the activation module and the cueing module each comprise a securement member configured to enable physical coupling and decoupling to the walking support structure or the waistband of the user.

9 . The device of claim 1 , wherein the cueing module further comprises:

a volume control potentiometer; and

a cadence control potentiometer configured to adjust an output rate of the metronome, the volume control potentiometer and the cadence control potentiometer each including a knob configured to be rotated by one or more fingers of the user.

10 . The device of claim 1 , wherein the metronome is configured to wirelessly communicate with any one of a headphone, ear buds, smart phone, tablet, and hearing aid.

11 . The device of claim 1 , wherein the cueing module further comprises:

a speaker in electronic communication with the metronome; and

a volume control potentiometer operatively coupled to the speaker, and wherein the volume control potentiometer is configured to adjust an output volume of the speaker.

12 . The device of claim 1 , further comprising a cable disposed between the activation module and the cueing module to electronically couple the activation module to the cueing module.

13 . The device of claim 1 , wherein the activation module and the cueing module are coupled through wireless communication.

14 . The device of claim 1 , wherein the cueing module further comprises one or more of a power switch or a motion sensor.

15 . The device of claim 1 , further comprising one or more sensors operatively coupled to at least one of the cueing module or the activation module.

16 . The device of claim 15 , further comprising computer memory operatively coupled to the one of more sensors, wherein the computer memory is configured to store data collected by the one or more sensors.

17 . The device of claim 16 , further comprising a remote computing device operatively coupled to the one of more sensors, wherein the remote computing device is configured to receive the collected data in real-time.

18 . The device of claim 15 , wherein the one or more sensors is configured to monitor data, the monitored data including one or more of walking speed, step count, time walked, gait quality, distance walked, stride length, a freezing of gait (FOG) event, number of falls, and time utilization.

19 . A device for cueing a user to take a step when experiencing a freezing of gait episode, the device comprising:

an activation module including:

a first housing configured to be physically coupled to and decoupled from a first location of a walking support structure;

a first elastomeric member having a first end secured to the first housing and a second end configured to detachably secure to the first housing whereby the first elastomeric member extends around a first portion of the walking support structure to detachably couple the activation module to the first location of the walking support structure;

an audible cueing activation switch supported by the first housing; and

a visual cueing activation switch supported by the first housing; and

a cueing module including:

a second housing configured to be physically coupled to and decoupled from a second location of the walking support structure;

a second elastomeric member having a first end secured to the second housing and a second end configured to detachably secure to the second housing whereby the second elastomeric member extends around a second portion of the walking support structure to detachably couple the cueing module to the second location of the walking support structure;

a source of a visual cue supported by the second housing; and

a source of an auditory cue supported by the second housing.

20 . A device for cueing a user to take a step when experiencing a freezing of gait episode, the device comprising:

an activation module including:

a first housing configured to be physically coupled to and decoupled from a first location of a walking support structure or a waistband of a user;

an audible cueing activation switch supported by the first housing; and

a visual cueing activation switch supported by the first housing;

a cueing module including:

a second housing configured to be physically coupled to and decoupled from a second location of the walking support structure or the waistband of the user;

a source of a visual cue supported by the second housing; and

a source of an auditory cue supported by the second housing; and

an electrical cable assembly including:

an electrical cable configured to electrically couple the activation module and the cueing module to one another, the electrical cable including a first end configured to connect to the first housing, and a second end configured to connect to the second housing; and

an adjustment member coupled to the electrical cable and configured to automatically adjust a length of the electrical cable as a distance between the first and second locations changes.
