Thanks for all the great @BiomechanicsDay posts, videos & memories shared this week! Refreshing, energizing & inspiring! @CREATEatVandy & I posted on a few social media sites. Compiling here into #NBD2020 ode to #biomechanics! What biomech is to us...

1/

#Biomechanics is about improving lives. Improving mobility & independence for those w/ disabilities. Preventing injury & sustaining health in others.

We aim to advance understanding of how people move, & translate science/engineering out of the lab.

#Biomechanics is studying human movement and musculoskeletal loading to inform how we design #wearables, #exoskeletons and #exosuits to support and protect manual material handlers and other workers in physically demanding jobs.

#Biomechanics is using #robotics to deepen our understanding of human walking and #musculoskeletal dynamics, so that we can design better medical interventions and improve patient care.

#Biomechanics is about using computational modeling to understand movement and envision the future of human augmentation. Then using engineering and design to fabricate and test these new #exoskeleton concepts.

#Biomechanics is also intentionally tripping the Dean of Engineering... and not losing my job nor the lab getting shut down as a result.

#Biomechanics is working with talented, dedicated students & multi-disciplinary collaborators, to advance our scientific, clinical and engineering understandings. Depicted are: Clinician + Postdoc + Grad Student + Undergrad Student.

#Biomechanics is using science to empower people to stay physically active and continue to do the things they love -- and to do them injury- and pain-free!

#Biomechanics is pulling on people with robots until they politely ask us to stop. To ensure wearable #exosuits & other #biomechanical assist devices we develop are comfortable, practical & effective for the people wearing them.

#Biomechanics is doing motion analysis lab experiments to understand human stumble recovery reflexes, then using this insight to design next-generation #prosthetic limbs that help prevent falls in individuals with limb loss.

#Biomechanics is studying how #prosthesis users perform tasks of daily living like squatting and lunging, to learn if and how we can improve prosthetic designs to overcome existing deficits, in order to improve quality of movement and quality of life.

#Biomechanics is about helping real people. Everyday heroes. By using science to develop tech that can support & sustain men and women who support & sustain all of us; like those in #logistics moving vital resources across the globe.

#Biomechanics is advocating for equity, inclusion and accessibility for all. It's about more than our specific research or our specific technology. It's about the impact we can have now, and the enduring impact we can have on the future.

#Biomechanics is also about messing up, failing, making mistakes & even feeling stupid. Science is hard. It's a humbling process that takes time, dedication & perseverance. Failures lead to learning & new discovery. Laugh, learn, enjoy the process.

15/

#Biomechanics is about being part of a global community of extraordinary people & organizations who are committed to science, outreach and societal impact. @CREATEatVandy thanks all who shared their science & passion this #NBD2020!

Exoskeletons in construction:

Nice article posted to the Associated Builders & Contractors of Wisconsin website & co-written by Prof. Zhenhua Zhu from UW-Madison & Mariya Sorenson, a construction manager with M.A. Mortenson.

They highlight 3 potential broad impacts of exos: Image
1. Improving worker safety & fostering a better safety culture in the construction industry.

Exoskeletons can reduce fatigue, muscle strain & wear-and-tear injuries, which could lead to substantial cost savings.
2. Alleviating the shortage of skilled construction workers.

Exoskeletons could help extend careers & attract candidates who might otherwise be deterred by physically demanding jobs.

🚀 5 years ago, I stumbled—somewhat unexpectedly—into the world of tech translation, commercialization & startups. It's been a wild & enriching adventure!

👨🏾‍🔬 As a scientist-turned-entrepreneur, this journey opened my eyes to the business world.

But...
😡 Amidst all the positive learning & growth, there's one thing that truly gets under my skin: misleading marketing & unsubstantiated claims.
😬 Brace yourself: The wearable & assistive tech industry (think #exoskeletons, #prosthetics, sensors) is still plagued by this problem! Whether it's in clinical, occupational, sport, or recreational applications, we need to address it head-on.

Now...

I spend a lot of time thinking about & discussing the science of #exoskeletons.

3 years ago, the single most common question I heard was:

❓Do exoskeletons cause muscle atrophy?

Short answer: No.

But I don't hear this as often anymore.

I believe there are 2 reasons why👇🏽
1️⃣ Science Communication

• For a long time, exo engineers/scientists mostly spoke to each other

• But now a broader audience is interested in exo tech

• And more researchers/developers are engaging in public discourse

This is helping reduce exo myths & misconceptions 👏🏽 🎉
If you want a quick rundown on:

• what causes atrophy (muscle weakening/wasting)

• why exos are more likely to prevent atrophy than to induce it

Where do your research ideas originate from?

I used to source all of mine from academic literature & conferences, or from my own research.

But these can become echo chambers that limit thinking & creativity.

🔥 Here are 4 overlooked places to find impactful research problems:
1️⃣ Your own life

• This is why I started studying low back #biomechanics
• I was a parent to young kids & experiencing back pain
• I was curious if we could create more practical exoskeletons that'd fit into my own life

It started as an undergrad project then grew into more:
2️⃣ Spending time w/ users

• In academia we often talk about this
• But we tend to involve users too late in R&D
• And I'm not convinced we spend enough time doing it

Hearing pain points directly from #prosthetics users is what prompted the daily activities we now study:

Science is the foundation, but user feedback is the north star:

• to know what to prioritize
• to learn where to improve
• to remember why you sweat all the science details

This is a vital lesson for those doing applied research whose feedback is mostly from other scientists
The combination of #biomechanics science and user-centric design is beginning to have the real-world impact the occupational #exoskeleton field long hypothesized it would.

End-users explain this best:
“When you show you care about people, that retains people,” one warehouse worker who piloted a back exosuit said. “Everybody in here, we’re all sore. We’re all hurting. But for the first time in a long time I won’t be hurting walking out of this building [because of the exosuit]”

Early career researchers often stress out when they talk to more senior faculty about how many grant proposals they submit.
 
Don't compare. Focus on your writing process. Outcomes will follow.
 
Here are 5 proven tricks senior faculty use to submit more high-quality proposals:🧵
1. Resubmitting

• Revise/resubmit an unfunded proposal
• This takes much less time than writing a new application

This is easier to do (and comes naturally) as you get further into your career.
2. Repurposing

• Take a similar core idea and apply it to a new population or context
• Or you can sometimes submit the same proposal to multiple agencies (check w/ program officers first; you just can't accept two grants for the same work)

This helps get more shots on goal.
