Pitt Researchers Develop Computational Model to Predict Friction of Shoes and Prevent Falls

Bioengineering

PITTSBURGH (April 20, 2018) … Slips and falls are one of the biggest causes of workplace injury in the U.S., and shoe choice can make all the difference in avoiding it. A proper shoe tread provides friction with the floor, which is necessary in preventing falling accidents. However, treads come in a variety of forms, and not all are designed to help prevent injury. A new computational model created by a team of researchers in the University of Pittsburgh Department of Bioengineering may help in the design of safer shoes. The project is led by Kurt Beschorner, associate professor of bioengineering at Pitt, and graduate student researcher Seyed Moghaddam, who conduct research in the Human Movement and Balance Laboratory in Pitt’s Swanson School of Engineering. Beschorner’s lab focuses on the development of ergonomic solutions for preventing falling accidents through biomechanics and tribology fundamentals. While a lot of research has been published on how surface features affect traction or friction, there remains a need to investigate actual shoe geometries to gather an understanding of the whole shoe-floor coefficient of friction. Beschorner’s latest findings are the result of a $1.5 million NIOSH R01 award he received in 2015 to better predict the wear rate of shoes. Beschorner and his team tackled this knowledge gap and recently published an article in the Journal of Biomechanics (doi.org/10.1016/j.jbiomech.2017.11.009) that discusses how they apply their computational model to measure and predict shoe-floor coefficient of friction. His lab is one of the first to use computational modeling to study friction between shoe and floor surfaces. Over the past three months, their publication has been the top downloaded article on the journal’s website. “Shoe-floor friction is influenced by microscopic and macroscopic features of the shoe and flooring,” said Beschorner. “Using our computational model, we can look at individual features to determine how it contributes to friction mechanisms.” “The model simulates shoe and floor interactions at multiple scales,” explains Beschorner. “This includes simulating the interaction of shoe and floor features at the micrometer scale as well as the visible scale. By combining information from these two scales, we can estimate the overall performance of the shoe.” Beschorner said, “In the end, this will enable us to develop safer shoes more efficiently.” The next step for this team is to work with footwear companies to integrate these methods in their design process. ###

Bioengineering and the Brain

Bioengineering

In January 2014, the University of Pittsburgh announced it would establish a new Brain Institute to “unlock the mysteries of normal and abnormal brain function, and then use this new information to develop novel treatments and cures for brain disorders.” Its founding scientific director, Peter L. Strick, PhD is Distinguished Professor & Thomas Detre Endowed Chair of the Department of Neurobiology and an expert on the neural basis of movement and cognition. He believes that the success of the program requires a multi-disciplinary approach that includes the Swanson School’s Department of Bioengineering. Dr. Peter Strick enjoys telling stories and speaks with a quiet passion that resonates with the history of neuroscience he has helped to build at Pitt. He also understands that it takes more than one discipline, one way of thinking to build upon that success and create a game-changing Brain Institute. “I started at Pitt 18 years ago as the co-director of the Center for the Neural Basis of Cognition (CBNC),” a joint venture between the University of Pittsburgh and Carnegie Mellon University, with Dr. Strick representing Pitt. “The Center took the comparable strengths of CMU robotics, computer science and statistics, and merged it with the strong neuroscience and clinical programs at Pitt. At the time, Pitt’s bioengineering program was in its infancy and wasn’t involved, but I saw that as a mistake. “Neural engineering and brain interface research was beginning to blossom and I truly thought that it could be a key player in the Center, especially because of its revolutionary work in tissue engineering.” Dr. Strick explains that bioengineering was key because of its inherent nature of being a multi-faceted discipline. “I related the potential of bioengineering to the beginning of my own career, as a neuroanatomist who cross-trained in my post-doc as a neurophysiologist. An eminent neurophysiologist told me that I would have to decide what I was going to be when I grew up.  Otherwise, I would be neither fish nor fowl – I wouldn't swim well or fly well. “Fifteen years later, when he saw me once more and it became apparent that the cross training had benefited my research [in utilizing viruses to understand neural circuitry], he said he was glad I didn’t take his advice. Neuroscience and bioengineering are similar in that both need to ask questions and then use whatever technique is most appropriate to answer them.  Bioengineers have the special challenge of combining training in hard core biology with the quantitative and computational approaches of engineering.” Dr. Strick believes that “it takes a University” to develop a leading program in brain research, one that taps into the multidisciplinary and open nature of collaboration between disciplines. One of his first recruits was Andrew Schwartz, professor of neurobiology with expertise in neural control. “Andy was responsible for the explosive growth of neural engineering research at Pitt, and led a pioneering group in brain-machine interface,” Dr. Strick says. “I saw its potential and the need to nurture and sustain it.” Dr. Strick explains that Dr. Schwartz shared his vision because he too understands the need to remove barriers to collaboration and take advantage of the open academic architecture of a university like Pitt. Over time the university would grow to include approximately 150 neuroscientists across disciplines, not including purely clinical colleagues. Dr. Strick says that the Swanson School’s Department of Bioengineering continues to play a key role in that growth, especially in Pitt’s growing expertise in neural engineering and brain-machine interface research. “The bioengineering faculty truly are a university resource, an intellectual resource that is active across all departments,” he explains. “The brain-machine interface program is bigger than a single department. It includes neurosurgeons who interact with physical medicine and rehabilitation scientists who work with patients to promote recovery, as well as the bioengineering faculty who explore everything from the electrode-tissue interface of brain implants to decoding neural signals to control robotic devices.” The brain-machine interface program captured international headlines when the team enabled patient Jan Scheuermann, a 53-year-old woman who suffers from a neurodegenerative disease and is paralyzed below the neck, to move a robotic arm and feed herself a bar of chocolate. The robotic arm was controlled via microeletrode arrays implanted into the surface of her cerebral cortex, enabling her to move the arm with her thoughts. “The success with Jan is a perfect example of how a multi-disciplinary program, built from the strengths of multiple departments in a major university and its medical school, can literally transform a life,” he says. Cross-disciplinary and cross-departmental interactions, as well as outside-the-box thinking were critical to the success of this project. “In the 1980s Andy proposed placing a monkey in a primate chair and training the animal to control an imaginary ball within a virtual reality environment,” Dr. Strick remembers. “People thought this research would lead nowhere, but in fact it was the foundation to allow a woman to control a robotic arm and feed herself chocolate.” WHAT MAKES A GREAT SCIENTIST AND BIOENGINEER? “There is a notion that individuals have brains with certain specific abilities that lead some of us to be writers, others to be mathematicians and scientists and still others to be artists.  According to this view, few of us have all of these abilities.  Thus, one doesn't normally expect the math genius to be the most communicative person in the room,” Dr. Strick says. “Today's modern scientist has to be multidisciplinary and broadly skilled to be successful.  He or she must write well, speak well and of course do science well.  The modern scientist must write grants that are clear and compelling and be able to communicate their ideas and findings to the lay public as well as to specialists in the field. “The modern bioengineer has an even more daunting challenge.  They must be cross-trained in math, physics, engineering, computer science and still think like a biologist.  Learning each of these disciplines is like learning a new language.  In a sense, bioengineers must be multilingual.  Not everyone is interested or even able to stretch in this way.  Our Bioengineering Department is unique in that it has attracted faculty who speak the many languages of science and recognize the value of multiple levels of analysis from cell and molecular approaches to whole systems and networks.” BUILDING A BETTER BRAIN INSTITUTE A major task of the Brain Institute, according to Dr. Strick, is to identify and provide the necessary research resources to enable world-class neuroscience at Pitt.  These resources include major equipment, outstanding faculty and research funding.  The most difficult part of this task is fundraising. “Our faculty do a wonderful job of obtaining federal grants to support their research. But, by all accounts, federal funding for research is shrinking,” Dr. Strick explains. “As a consequence, we are in danger of shutting off the pipeline for discovery.  Our representatives and the general public want the field to translate results into new treatments and cures for neurological and neuropsychiatric disorders.  However, this translation depends critically on new discoveries that come from basic fundamental research. “In essence, without new discoveries, there is nothing to translate.  A major task of the Brain Institute is to identify financial resources that can enable us to keep the pipeline of discovery open.” As noted earlier, the core mission of the Brain Institute is to unlock the mysteries of normal and abnormal brain function, and then use this new information to develop novel treatments and cures for brain disorders.  “I see bioengineering as a major player in this mission,” Dr. Strick says. “Indeed, the faculty and students at the Swanson School and in the Neural Engineering Track are posed to make major contributions to new areas of neuroscience such as multi-modal neuro-imaging with PET, MR and MEG; neuromodulation with deep brain stimulation, and neuro-technology with brain machine interfaces.  Faculty in Bioengineering like Aaron Batista, Tracy Cui, Raj Gandhi, Takashi Kozai, Gelsy Oviedo-Torres, and Doug Weber are all involved in cutting-edge research.  The success of the Brain Institute will depend in part on the efforts of this vibrant faculty.”

“Tic-Tac-Toe”-Themed MRI Technology Easy Win for Neurological Disease Researchers

Bioengineering

PITTSBURGH (April 12, 2018) … The University of Pittsburgh houses a whole-body 7 Tesla magnetic resonance imager (7T MRI), one of the strongest human MRI devices in the world and a powerful imaging tool that allows researchers to gain a far better understanding of brain structure and function. Tamer Ibrahim, associate professor of bioengineering in Pitt’s Swanson School of Engineering, runs the Radiofrequency (RF) Research Facility and conducts experimental and human studies with this device - one of only five dozen 7T MRI machines in the world. Over the past two years, in collaboration with Pitt’s Departments of Psychiatry and Epidemiology, Ibrahim’s lab has received close to $5 million from multiple NIH grants that total more than $18 million and extend through 2022. These awards fund the development and use of innovative 7T human imaging technologies. Ibrahim and his team of bioengineering graduate students constructed and optimized the “Tic-Tac-Toe” RF coil system for 7T human MRI devices. This system is a collection of transmit antennas and receive antennas that are tightly arranged to fit the human head.  It was designed through many hours of computer simulations using full wave electromagnetic software developed in his lab. Though advancements have been made, several major obstacles still face neuro 7T imaging such as considerable scanning and preparation time for every subject; significant RF excitation intensity losses; potential RF heating; and concerns regarding the unclear RF safety assurance between different subjects. “The Tic-Tac-Toe RF coil system is a novel design that addresses many of the technical difficulties associated with ultrahigh field human MRI,” said Ibrahim. “Our system provides highly consistent and homogenous excitation across different patients, which in turn provides improved images.” In collaboration with Howard Aizenstein (MPI), Charles F. Reynolds III and Ellen G. Detlefsen Endowed Chair of Geriatric Psychiatry at Pitt, Ibrahim recently became PI/PD on an NIH R01 grant where he will use the technology developed in his lab to investigate small vessel disease in older adults with depression. This disease affects a large amount of the American population, but research has been hindered in part due to the inadequacies of traditional imaging. 7T diffusion fiber tracking. In this $3.1 million project, Ibrahim uses the “Tic-Tac-Toe” RF coil system and develops a new 7T RF coil system to better understand the neurological issues, treatment, and management of depression. “White matter hyperintensities (WMH) in the brain are a hallmark symptom of small vessel disease, which has been associated with depression in older adults,” explained Ibrahim. “Traditional MR imaging does not provide enough detail; thus, researchers cannot determine the specific mechanisms that contribute to depression. Ultrahigh field MR imaging allows for greater specificity of the WMH lesions and other components of small vessel disease, which will give us a better understanding of depression as a whole.” In addition to their work with depression, Ibrahim’s developed technology has contributed to research in a variety of other neurological diseases such as Alzheimer’s disease, schizophrenia, sickle cell disease, and major depressive disorder. Ibrahim’s lab is composed entirely of graduate and undergraduate students who aim to develop highly technical RF devices, which they typically get to implement into clinical studies. “We have applied our work to several patient and disease studies at Pitt,” said Ibrahim. “Our lab’s research is unique because its roots are in engineering and physics, but it has now matured to extensive patient-level studies.” “It has been interesting to see our work go from engineering and physics concepts to real-world applications,” Ibrahim continued. “This is a great example of how engineering innovation done in the Swanson School of Engineering translates into medicine.” ###
