Software Technology

Biotonix's core technology is a web-based, imaging software system which is easy to use, non-invasive and provides a complete individualized assessment of musculoskeletal form and function, postural deviation detection, and corresponding corrective exercises.

Light-reflective anatomical markers are placed at specific locations on the body, and a series of four pictures from different views are then taken by digital camera. The markers enable gathering data for the biomechanical analysis. The entire process takes a maximum of ten minutes for each individual. The Biotonix application then scans the pictures to extract the coordinates of each marker on the body. These anatomical location coordinates are then sent over the internet to Biotonix data center servers for the biomechanical analysis to be performed.

The Biotonix system computes many fundamental biomechanical variables that allow determining joint compression forces, deviations from vertical and horizontal alignment, and the center of gravity. Muscle functions underlying these biomechanical properties are then analyzed. This results in a Biotonix report which includes a detailed assessment of posture and biomechanics as well as related individualized stretching and strengthening exercise programs, designed to correct and improve postural deviations and muscle imbalances.

All aspects of the Biotonix system are based on well-established scientific principles, and the exercises are guided by world recognized guidelines, recommended by authorities, and research at the UQTR and McGill University which has shown the system to be both highly valid and reliable.

Biotonix provides an automated biomechanical assessment tool that uses web-based technology to detect postural deviations and automatically generate personalized corrective exercise programs. Light reflective anatomical markers are placed at specific locations on the patient's body. Four digital pictures are taken of the patient from the lateral, anterior, and posterior views. Web-based software is used to scan the images and extract the anatomical coordinates of each marker. Data are sent to a centralized data processing centre. The identity of the client is protected, since only the location of the markers is sent via the web. A completely automated biomechanical analysis is completed. An individualized BioPrint is produced for each client providing a detailed explanation and illustration of his or her biomechanical state, postural deviations, underlying muscular factors, and corrective exercise plan. Follow-up evaluations and comparison reports assess patient progress.

The light reflective markers are placed over anatomical landmarks that correspond to vertical and horizontal plumb lines. Consequently, these markers define optimal posture according to the most respected model of posture provided by Kendall et al. When markers deviate from plumb (or level) this means that body segments or reference points deviate from proper alignment. That is, there is a postural deviation.

Deviations are prioritized to be targeted for exercise intervention using the magnitude of the deviations and the contribution of the body segment to overall postural stability. Biotonix bases its consideration of the contribution of body segments to overall postural stability on the model provided by Kendall et al. and Watkins. These models consider pelvic and trunk stability to be crucial to postural stability. Consequently, the trunk, pelvis, and hips are targeted first with other deviations treated with lower initial priority. Biotonix's exercise treatment for postural deviations is based on the theoretical model that deviations (of non-orthopedic origin) result from an imbalance of activation of antagonist muscles acting on joints. Some muscles are hyper contracted and some are hypo contracted. Goal is to strengthen the weak muscles and stretch the over-developed muscles. The specific stretching and strengthening exercises are based on extensive clinical consultation and Exercise physiology protocols provided by such authorities as the American College of Sport Medicine.
