Inference of the stress field of a cell sheet
The mechanical behavior of living tissues is deeply connected with many important biological questions, yet little is known about internal tissue mechanics. Since the traction forces exerted by cells on a planar, deformable substrate can be measured, we propose to combine traction force data with Bayesian inversion to estimate the internal stress field of a cell sheet. The method is validated using numerical simulations performed in a wide range of conditions. It is robust to changes in each ingredient of the underlying statistical model. Importantly, its accuracy does not depend on the rheology of the tissue. Combining Bayesian inversion with Kalman filtering allows to process time-lapse movies of the traction force field. As an example of application, we provide an estimate of the tissue stress field close to cell delaminations in an epithelial cell monolayer.

Forging Mens et Manus: the MIT Experience in Upper and Lower Extremity Robotic Therapy
The field of rehabilitation robotics has grown steadily over the past decade, making significant clinical contributions. Studies have demonstrated both the efficacy and advantages of robotics for assessing and treating motor impairment. Recent guidelines, such as the 2010 AHA American Heart Association’s “Comprehensive Overview of Nursing and Interdisciplinary Rehabilitation Care of the Stroke Patient,” endorsed the use of rehabilitation robotics for upper extremity rehabilitation. The same is true of the 2010 VA/DOD guidelines. The recent 2016 AHA guidelines reaffirmed the same standing. The purpose of this talk is (1) to provide a concise yet broad-based review of the neuroscience basis of motor rehabilitation for the upper and lower extremity, (2) a historical perspective on how the field has developed, (3) review the state-of-the-art for upper extremity robotics, (4) and lower extremity rehabilitation robotics, and (5) describe on-going research at MIT.
