Sistens enables users to submit two pictures which we then use to create your BioStructural Analysis report. The purpose of the analysis is to look for structural deviations of the body so we can recommend corrective techniques & exercises. BioStructural deviations have been shown to lead to degenerative disc disease (DDD) and/or osteoarthritis (OA) of the spine. Correcting these deviations helps prevent DDD & OA from occurring and improves overall health, performance, spinal hygiene, and well-being.
