Standing up from a chair is something most people take for granted, but for many who undergo total knee arthroplasty (TKA), that simple action can remain frustratingly difficult. Researchers analyzed movement and muscle function in patients before and six months after surgery using dynamic musculoskeletal simulations. They examined how joint motion, muscle forces, and knee extension strength contributed to the sit-to-stand movement, finding: 🔹 Quadriceps weakness persisted after surgery, with no significant changes in muscle forces or contributions to acceleration. 🔹 Despite surgical intervention, overall movement patterns and joint mechanics remained largely unchanged during the sit-to-stand motion. 🔹 Patients relied on compensatory muscle strategies before and after surgery, limiting improvements in functional performance. Even after TKA, the consistent movement patterns observed in this study signal opportunities to refine rehabilitation by focusing on muscle strength and control to improve real-world mobility.

A great convo with OSU MAE Grad Students & 2 other great @OhioStateMAE alumni about post-PhD career paths. There are certainly differences between academia/industry/national labs, but I think you'll hear more commonalities than differences! youtu.be/pmz5xHrn1vc?si=FAZS…

I had the pleasure of being interviewed by Nehal Jajal & @K_Blessinger for the @OhioStateMAE MEGA Alumni Podcast. Thanks for the great conversation & opportunity to discuss mental health, motherhood, & my experiences in academia. #AcademicTwitter youtube.com/watch?v=QfjuEgcL…

Given that I work in a field that values the health benefits of physical activity, it's ironic how much time I spend at a computer simulating human movement. #biomechanics

For the record, brave people who make hard decisions to focus on their mental health are not “quitters”. Do better @nbc4i. We are very proud of @h_miller76 at @OhioStateMAE

Prof. Rob Siston has been named chair of the Department of Mechanical and Aerospace Engineering, effective February 1. An @OhioState alum, he's taught at Ohio State since 2006 & holds appointments in @OhioStateMAE, @OhioStateBME, @osuhrs & Orthopaedics. engineering.osu.edu/news/202…

Fantastic presentation this morning by fellow buckeye Prof. Agarwal (@OhioStateMAE @OhioStateBME) on the interdisciplinary nature of bioengineering! #imece2022 @ASMEdotorg #GoBucks

Kudos to Anne Kloos, PT, PhD, clinical professor & board-certified clinical specialist in neurologic physical therapy at @osuhrs, who recently received the American Physical Therapy Association’s Humanitarian Award. 👏👏👏

Great talk yesterday by Fariha Haque (@OhioStateMAE) on additively manufactured cranial implants at #IMECE2022! @ASMEdotorg @AlokSutrad #GoBucks

Come visit the Ohio State MAE booth (Booth 402) at the @ASMEdotorg IMECE Conference from 12-5 p.m. to learn about our research, graduate programs and more.

Are you a #clinician #researcher in interested in #KneeOA #osteoarthrits? Our recent #webinar on new insights and emerging technology-based is now online. Six great talks from leading academics. Click here to watch the talks: oatechnetwork.org/events/web…

Ayonga Hereid, Asst. Prof. in @OhioStateMAE, has earned a $600K Faculty Early Career Development (CAREER) award from @NSF for his work on humanoid robots and lower-limb exoskeletons. #BuckeyeEngineering #Robotics engineering.osu.edu/news/202…

I'm excited to share the first study from my PhD work. Motor modules are malleable after TKA. Thanks to @SarahRoelker, Jeff Pan, Laura Schmitt, @BiomechAjit, and @ProfSiston for their hard work and support! #PLOSONE: dx.plos.org/10.1371/journal.…

We were a small group this year for #ORS2022 but promise to drag @ProfSiston out for the next one! It was great to connect with some colleagues and to have met many more! Always great science at the @ORSsociety.

And that's a wrap! Great first time at #ORS2022 @ORSsociety
