Abstract
Abstract A system for maintaining a desired spinal curvature of a user suffering from improper alignment of the vertebrae of the spine. In it's broad aspects, it comprises a sensor feedback system and electrodes. The sensor feedback system measures spinal curvature, determines whether selected conditions have been met warranting the application of electrical stimulation and provides information regarding the determination to an electronic stimulator. The electrodes are spaceably mounted on selected portions of the user's back. They are in electrical communication with the electronic stimulator for causing contraction of the back muscles at selected levels, thus providing alignment of the spinal vertebrae. The sensor feedback system includes a sensor assembly which comprises an upper elongated rigid segment, a lower elongated rigid segment and a sensor. The upper elongated rigid segment is positionable adjacent the user's upper spine. The lower elongated rigid segment is positionable adjacent the posterior pelvic region. The sensor is mounted on a flexible middle segment between the upper segment and the lower segment. The sensor is so positioned as to measure lordosis.

Claim 2
Independent Claim
130 words
A system for use with an electronic stimulator for maintaining a desired spinal curvature of a user suffering from improper alignment of the vertebrae of the spine, comprising: a) a sensor feedback system for measuring spinal curvature to obtain a spinal curvature measurement, determining, using the spinal curvature measurement whether selected conditions have been met warranting the application of electrical stimulation and providing information regarding said determination to an electronic stimulator including connecting means for electrically connecting the sensor feedback system to said electronic stimulator; and b) electrodes electrically connected to said connecting means spaceably mountable on selected portions of the user's back adapted to be in electrical communication with said electronic stimulator for causing contraction of the back muscles at selected levels, thus providing alignment of the spinal vertebrae.
Claim 3
Dependent Claim
72 words
