Spine Detail for Biomechanical Analysis

Movements of the individual vertebra in the spinal columns can now be analyzed with The MotionMonitor's spine detail functionality. This product is ideal for both in-vitro labs and clinical applications where quantification of spinal motion is required. Multiple sensors are assigned to individual vertebra of the spine. Anatomical landmarks are then digitized to define the dimensions of each vertebra in the segment. Alternatively, use the "default" axis layout for fast set-up in a clinical setting.

An image of a forward flexion movement for a healthy 26 year old athlete is shown on the left. The data on the right is from a 45 year old sedentary lawyer with back pain.  In the detail spine animation, the vertebrae that appear in white have sensors attached to them. In this example, sensors were assigned to T1, L1 and the sacrum for tracking these individual segments as well as the movement of their respective spinal columns. The graphs display the degrees of Lumbar Flexion, Flexion Velocity and Flexion Acceleration. While the range of motion is similar for each, note the differences in the smoothness of velocity and acceleration data for two subjects.
