A binodal wireless sensor provides biomechanics feedback focused on movement tracking for the purpose of facilitating enhanced user training and recovery decisions. The sensing device and methods of use differs distinctly from current devices by utilizing a plurality of inertial sensors within a single, non-rigid unit to, among other things, identify a segment's position in space, identify internal movement and stability such as torsion, bending, shear movement, etc. in the segment, and/or between two segments. The unit includes data storage, wireless transmission, rechargeable battery, local processing and data collection sensors. The unit relays data to an intelligent device that provides feedback to the user.
