## Abstract

The present disclosure describes methods, sensors, and systems for detecting movement of a spine and stimulating specific regions of the spinal cord in response to the movement. The disclosure includes sensors having one or more sensing elements to sense movement of the spine and one or more stimulating elements configured to electrically stimulate an area proximate the spine. When a movement of the spine is detected via the sensor, the one or more stimulating elements modulate an electrical stimulus.

## Claims

### Claim at position 1

1-66. (canceled)

### Claim 67

A method of detecting movement of a spine, and stimulating specific regions of the spinal cord, the method comprising:
providing a sensor having one or more sensing elements to sense movement of the spine;
providing one or more stimulating elements configured to electrically stimulate an area proximate the spine;
detecting, via the sensor, a movement of the spine;
modulating an electrical stimulus provided by the one or more stimulating elements at an area proximate the spine in response to the detected movement; and
arranging the one or more sensing elements such that the one or more sensing elements align with a direction of deformation of the sensor.

### Claim 68 (depends on 67)

The method of claim 67, wherein the one or more sensing elements each include a first set of sensing elements and a second set of sensing elements.

### Claim 69 (depends on 68)

The method of claim 68, wherein the first set of sensing elements is substantially aligned with the second set of sensing elements when the sensor is in the initial state.

### Claim 70 (depends on 68)

The method of claim 68, wherein the first set of sensing elements is offset from the second set of sensing elements when the sensor detects movement.

### Claim 71 (depends on 67)

The method of claim 67, wherein the sensor includes a resistive layer disposed between a substrate and the one or more sensing elements.

### Claim 72 (depends on 71)

The method of claim 71, wherein the substrate is a flexible substrate.

### Claim 73 (depends on 71)

The method of claim 71, wherein the resistive layer is formed via deposition of conductive ink on the substrate.

### Claim 74 (depends on 71)

The method of claim 71, wherein the resistive layer is formed via embedding conductive ink or particles within a silicone.

### Claim 75 (depends on 71)

The method of claim 71, wherein the sensor includes overmolding disposed on the resistive layer, the one or more sensing elements being disposed within the overmolding.

### Claim 76 (depends on 67)

The method of claim 67, wherein detecting movement comprises:
comparing an altered property value to a threshold value;
determining that the altered property value exceeds the threshold value;
calculating a difference between the altered property value and the threshold value in response to the determination that the altered property value exceeds the threshold value; and
based on the difference, calculating a spinal deviation, wherein the spinal deviation includes one or more of flexing or twisting of the spine from an initial spinal position to a deviated spinal position.

### Claim 77 (depends on 76)

The method of claim 76, wherein the deviated spinal position is due to flexing of one or more muscle located proximate to the spine.

### Claim 78 (depends on 76)

The method of claim 76, wherein the stimulating elements provide cervical spinal cord stimulation for treatment of neurological disease, disorders, or injuries.

### Claim 79 (depends on 67)

The method of claim 67, wherein detecting movement of the spine comprises:
measuring an initial property value;
continuously measuring an altered property value;
calculating a difference between the altered property value and the initial property value; and
based on the difference, continuously calculating a spinal deviation, wherein the spinal deviation includes one or more of flexing or twisting of the spine from an initial spinal position to a deviated spinal position.

### Claim 80 (depends on 79)

The method of claim 79, wherein the movement of the spine is due to flexing of one or more muscle and/or skeletal structures located proximate to the spine.

### Claim 81 (depends on 79)

The method of claim 79, wherein the initial property value and the altered property value are different.

### Claim 82 (depends on 79)

The method of claim 79, wherein the initial property value is an initial resistance value, and the altered property value is an altered resistance value, the initial resistance value and the altered resistance value associated with a resistance of the sensor.

### Claim 83 (depends on 79)

The method of claim 79, wherein the initial property value is an initial capacitance value, and the altered property value is an altered capacitance value, the initial capacitance value and the altered capacitance value associated with a capacitance of the sensor.

### Claim 84 (depends on 67)

The method of claim 67, wherein one or more gaps are disposed between each of the one or more sensing elements.

### Claim 85 (depends on 67)

The method of claim 67, wherein the movement of the spine includes torsion or flexion of the spine.
