Abstract

Devices and systems for characterizing a condition of spinal deformities are contemplated. Mobile devices that incorporate inclinometers or accelerometers (e.g., a smart phone) are held securely in a supporting structure that renders it useful to characterize spinal deformities such as scoliosis and/or kyphosis. Supporting structures can include features that secure the mobile device (for example, chamfered surfaces, high friction surfaces, pliant projections, straps, hook and loop enclosures, tensioning devices, detents, etc.) in an upper portion and a lower portion that includes at least one, but preferably two or more rollers, and an interposing centrally placed notch dimensioned to permit the assembled device (supporting structure and mobile device) to span the width of a typical human spinal column. At least one roller includes an encoder (e.g., optical, mechanical, and/or magnetic encoders) that provide data related to their rotation or translation, thereby providing a measure of distance travelled as the device rolls, as well as direction. Such a support device can include additional features, such as additional sensors that are accessible by the mobile device, a centrally placed guide (such as a projected LED laser, illuminated filament, flexible bristle, etc.) that can be used to keep the assembled device in alignment during use, and supplementary battery power for the mobile device.
