OpenSim simulations yield insights into the design of assistive devices to reduce the metabolic cost of running

Mobilize Center researcher Thomas Uchida and OpenSim researchers published a paper in PLOS One where they generated muscle-driven simulations of movement to augment experimental data and provide insights into the design of assistive devices to reduce energy consumption during running.

Using the open-source OpenSim software platform, they simulated 10 human subjects running at 2 and 5 m/s to examine the predicted changes in muscle recruitment patterns and metabolic power consumption with assistive devices.

Results from the simulations yielded observations that can be used to form hypotheses for future experimental studies.

Analysis of 600,000+ crisis hotline text messages identifies successful counseling techniques

Mobilize Center graduate student Tim Althoff and Mobilize Center faculty member Jure Leskovec published a research paper in the Transactions of the Association for Computational Linguistics Journal where they conducted a large-scale quantitative analysis of over 600,000 text messages from 15,555 counseling conversations. They developed novel computational methods such as a sequence-based unsupervised conversation model and psycholinguistics-inspired word frequency analyses to learn how various linguistic aspects of conversation are correlated with conversational outcomes.

Results from the analysis yielded five strategies that successful counselors utilize. Read the full article

NIH Rehabilitation Research Conference Highlights Role of Technology and Big Data

The NIH is hosting a conference “Rehabilitation Research at NIH: Moving the Field Forward” on May 25-26, 2016 to discuss the range of rehabilitation research projects funded by the NIH and to gather feedback on the development of the recommendations for the NIH Rehabilitation Research Plan.  Panel discussions include a discussion of telemedicine and smartphone apps in rehab (“Bending the Arc of Technology Toward Rehabilitation and Health) and the use of big data in rehab (“Using Data to Drive Discovery”). Dr. Jennifer Hicks, the Mobilize Center Director of Data Science, will present a talk on how our Center uses data from wearable sensors, research labs, and clinics to understand and improve human mobility.

The full agenda is available here.  The event will also be webcast:

Abby King Discusses the Key for Behavior Change at mHealth Connect

At last week’s mHealth Connect, Abby King highlighted the need to personalize incentives for behavior change. How to select the right approach for motivating an individual, though, should come from an analysis of the individual’s behavior, not from asking the individual about her preference.

Read more about this idea in a piece written by David Shaywitz, the moderator of the panel on which Abby King participated. A recording of the discussion will also be available.

Announcing Panel Discussion “Consumer Wearables: The Path to Clinical Application”

As the wearables market continues its remarkable growth, there is an increased awareness and interest to utilize this technology for clinical and research purposes. The ability to gather information from patients 24/7 on a long-term basis and to study and influence the behaviors and health of millions of individuals in real-time has the potential to radically transform medicine, health policy, and biomedical research. How close is this vision to becoming a reality? What are the barriers to this vision and what can be done to overcome them?

This panel features four individuals who are paving the way for the use of physical activity wearables and apps for clinical purposes. They will describe how they are leveraging consumer devices and apps for a diverse set of clinically related applications, ranging from orthopaedic diseases to autism to health promotion. In the follow-up discussion, they will describe the challenges they have encountered along the way and share their thoughts on what it will take to fulfill the vision of using consumer wearables for clinical and research applications.

When:  Thursday, March 17, 2016 from 9:45am – 11:00am Pacific Standard Time
