Description: Caregivers experience back injury at alarming rates. Portable tools are needed for performing biomechanical evaluations of caregiving work in the field to determine which activities cause back injury. This work describes the design and validation of portable motion capture devices developed for this purpose. Two novel portable motion capture systems were developed. The performance of the novel systems was compared to an existing motion capture system for their ability to estimate resultant forces at the L5/S1 joint by finding the relative three dimensional positions of the L5/S1 joint and feet. The first system (FootCam) was found to estimate resultant forces with insufficient accuracy due to poor coupling of the device with the subject's body. This coupling error was due to inertial effects and bulk tissue movement. The second system (semi-portable) was found to be sufficiently accurate to serve as a portable replacement for existing motion capture systems.
