Novel Musculoskeletal Loading and Assessment System (MLS), Year 2

The 4 main objectives in this FY'17 effort include: 1) improve the MLS bar electronics by installing full inertial measurement unit (IMU) systems, load cells, and improved Bluetooth technology; 2) ruggedize the MLS and fabricate a telescoping bar design; 3) add sensorimotor assessment and countermeasures capabilities using the WalkasinsTM system; 4) develop a novel data processing platform to integrate sensor, load, and positional data to assess sensorimotor function and provide a surrogate measure of ground reaction force. Industry and academic efforts in the sensorimotor area are typically conducted in large laboratories and include ambulation tasks and balance challenges. Testing and training sensorimotor function during exploration missions, without treadmill availability for ambulation, and within limited volume provides a very unique set of challenges that is not currently being explored by other efforts. Development and testing results of this device will be shared with the HRP's Advanced Exercise Concept team and ISS Exercise Engineering teams, as it is directly related and informative for next generation exercise devices. This hardware development and integrated analysis of pressure sensor, IMU, and load data has tremendous potential beyond spaceflight as a tool for individuals inflicted with neuromuscular diseases and stroke patients.
