- Description
- QUESTION: My lab has the required resources and capabilities for the fulfillment of the listed tasks in the solicitation. However I was wondering if you want all the required data processing to be exclusively conducted within the motion tracking system software? Motion tracking software offer limited capabilities for biomechanical analyses and we have offen exported the collected kinematics and kinetics data within the software to process them in computational platform like MATLAB and ABAQUS finite element software. We have been doing a similar projects (Funded by NIH) with collaborators from Walter Reed National Military Medical Center (I have attached a sample paper). For that project, we simply get the de-identified kinematics and kinetics data collected at Walter Reed Biomechanics lab (exported from Vicon Motion tracking System) and perform all simulation of spine biomechanics (i.e. equilibrium and stability analyses through estimation of trunk neuromuscular behavior and resultant spinal loads and stability using our finite element computational plat form). We have also been using a similar approach in our investigations of the effects of body armor on postural balance (i.e., using continues relative phase analyses in MATLAB software). Would NIOSH investigators accept an offer that involves processing and analyzing the collected date outside of the motion tracking software? ANSWER: Yes. We will process our data solely using Vicon motion capture system and Nexus motion capture software. This possible contractor's expertise is in the finite element modeling of the spinal biomechanics. We agree that is a good approach to investigate the precise mechanism of the initiation and development of the spinal injuries and musculoskeletal diseases using finite element analyses (FEAs). However, this is not the purpose of our study. The purpose of our study is to access the postural and kinetics effects during actual manual material handling that may contribute to MSDs and postural instability. The development of the FEA model of the spinal vertebra/discs would need the knowledge of the muscle forces and exact kinematics of the vertebral bones. We will not do inverse dynamical analysis to calculate the forces in the spinal muscles. In addition, in our measurements using Vicon system and Nexus software, we would not try to determine the kinematics of the spine in a precision for the purpose of a FEA modeling. The general interest of our study is to ergonomically evaluate general material handling methods of masonry workers, not to develop a patient specific model, like in a clinical study.
