Outstanding Paper Award for Surgical Science from the Spine Journal

Mobilize Center faculty Matthew Smuck and colleagues won the 2017 “Outstanding Paper: Surgical Science” at the North American Spine Association (NASS) 32nd Annual Meeting for their paper“Objective Measurement of Function following Lumbar Spinal Stenosis Decompression Reveals Improved Functional Capacity with Stagnant Real-Life Physical Activity” in The Spine Journal. Results showed improvements in self-reported function and objectively measured physical capacity 6 months post-surgery, but not in physical performance as measured by continuous activity monitoring. Read more.

NIPS “Learning to Run” Challenge Winners Announced

NNAISENSE, an artificial intelligence company based in Switzerland, beat out 441 other participants to win first prize in the “Learning to Run” competition co-organized by researchers from UC Berkeley, EPFL, and the Mobilize Center. The competition was part of the Neural Information Processing Systems (NIPS) 2017 Competition track. In the competition, participants were tasked with developing a controller to enable a physiologically-based human model to navigate a complex obstacle course as quickly as possible. NNAISENSE’s model ran at 4.60 m/s. The second prize winner’s model (Beijing University, China) ran at 4.17 m/s, and the third prize winner’s model (, USA) ran at 3.84 m/s. View a video summarizing the competition and showing simulations of the submitted models.

Stanford Health++ Hackathon

The Mobilize Center is excited to be a co-sponsor for the Stanford Health++ Hackathon. This event brings together engineers, designers, healthcare professionals and business experts to collaborate, design and create models and solutions for healthcare affordability here in the US and internationally. This two-day health hackathon will take place October 21-22, 2017 at Stanford University, Huang Engineering Center. Click here to register to participate, mentor, or pitch a need. Featured speakers include Lloyd Minor, Dean of Stanford University School of Medicine.

Highlights of “Data Science in Biomechanics” Thematic Session at ISB 2017

The Mobilize Center organized the thematic session on “Data Science in Biomechanics” at the 26th Congress of the International Society of Biomechanics (ISB) in July. The thematic session generated a lot of interest with over 160 people in attendance. The talks highlighted various data science topics including: 1) how large data from wearables, clinics, and research labs are leading to new actionable insights, and 2) how data science tools can help generate new knowledge that conventional statistical methods may miss.

First Annual eWear Student Symposium

Mobilize Center postdoc Łukasz Kidziński is co-organizing the first annual eWear student symposium taking place Thursday September 7, 2017 at Stanford University. This one day symposium will highlight research on the impact of wearable technology and inspire discussion, generation of ideas, and opportunities for collaboration. Keynote speakers include: Dr. Bill Liu, Founder and CEO of Royole Corporation; Michael S. Eggleston from Bell Labs; and Hind Hobeika, inventor and developer of the first version of Instabeat. Mobilize Center graduate students Tim Althoff and postdoc Jessilyn Dunn will also be speaking at the symposium. Read more and register.

Analysis of Physical Activity Data from Over 700,000 Worldwide Users Reveals Physical Activity Inequality

Mobilize Center faculty member Jure Leskovec and colleagues published a paper in Nature this week where they analyzed physical activity data from over 700,000 users of a smartphone fitness app. Their analysis shows that the disparity of physical activity distribution within a country, what they refer to as “activity inequality,” is a better predictor of obesity levels within a country than average activity levels. In other words, the greater the activity inequality or activity disparity is in a country, the higher the prevalence of obesity. They also identify associations between a city’s walkability and activity inequality. Visit to access findings from the study, including data and code. Read more.

Multivariate Pattern Analysis of Physical Activity and Cartilage Health in Osteoarthritis

Mobilize Center postdoc Eni Halilaj presented her work on the role of physical activity on early progression of knee osteoarthritis (OA) at the World Congress on Osteoarthritis (OARSI) 2017 in April. Using data from the Osteoarthritis Initiative, she and co-authors recently showed that multivariate statistical methods can generate new insights on the ranges of activity intensity that are protective and detrimental for joint health, which are missed by conventional statistical tools. Read abstract and view poster.

“Data Science in Biomechanics” Symposium at ISB 2017

The Mobilize Center has organized a symposium on “Data Science in Biomechanics” at the 26th Congress of the International Society of Biomechanics (ISB) taking place July 23-27, 2017 in Brisbane, Australia. The symposium will highlight current applications of data science methods in biomechanics research, foster discussions of the challenges and opportunities with biomechanics data, and promote the sharing of data and knowledge within the community.
