Through digital and analog integrations, the QTM software records synchronized data from the Qualisys cameras, two additional HD video cameras, five force platforms, an instrumented staircase, a 16-channel wireless EMG and inertial sensor system, and a strength testing dynamometer.
A unique aspect of this lab is the use of quantitative MR imaging techniques to assess the impact of movement biomechanics on hip and knee joint tissues health. The researchers use a state-of-the-art imaging facility at Boston University with a 3.0 Tesla MRI to quantify cartilage, muscle, and bone structure and composition in the populations of interest.
This allows them to combine measures of joint loading from the motion capture system with high resolution data on tissue health to assess biomechanical mechanisms of disease and outcomes of clinical interventions with high sensitivity.
Optical Tracking and Inertial Sensors
The motion capture system is also used to validate wearable sensors, particularly inertial sensors, for use in measuring quantity and quality of movement outside the lab in free living conditions. These sensors are incorporated into innovative mobile health solutions for intervention monitoring and delivery.
