I wish I learned this tip earlier in my career:

👉🏽 If you do R&D on wearable or assistive tech, wear/use prototypes regularly in your daily life. It helps empathize with end users. And improves your ability to design and test for usability & practicality.

Here's why (brief 🧵)
1. It builds your intuition.

In retrospect, this tip seems obvious. But most researchers & developers don't do it. It took me >10 years of biomedical R&D to realize it. 

Once I did, it transformed how I evaluate and develop new #exoskeletons, #prosthetics, #bionics & #wearables
2. It provides clarity.

You'll notice design constraints you never knew existed. You'll think more deeply about user experience. And you'll create better lab and field evaluations more quickly.

It helps preempt fatal flaws before you start any serious design or testing work.
This advice has been so impactful to my own R&D that it feels more like a cheat code than a tip.

Give it a try yourself! Post your own suggestions or questions. Or read more about my somewhat unorthodox approach to #biomechanics & wearable tech R&D:

💡 Tip for early career researchers: Sometimes you need to TELL, not ASK.

❌ Instead of asking your organization or boss: "How do I do X (procedure)"

✅ For truly important matters, tell them: "Y (goal) is what I'm striving to accomplish" or "Y is what I need to be successful."
PhD student example:

❌ "How do I find an industry internship?"

✅ "I really need to get some industry experience during graduate school to set me up for success in what I want to do next in my career."
PI example:

❌ "How do I get invited to participate on a grant review panel?"

✅ "It's really important for me to serve on a grant review panel soon to help me improve the competitiveness of my proposals."

This week, I enjoyed visiting the vibrant, creative, & interdisciplinary researchers in @jointbme @CLEAR_NCSU_UNC.

I gave a seminar on lessons from translational #biomechanics R&D.

I shared 6 actionable tips to improve iterative, user-centric development in academic labs: 🧵
@jointbme @CLEAR_NCSU_UNC 1. Spend more time with users

• Get to know users deeply
• Don't focus conversations on your research/tech
• Give time for users to discuss their life & pain points

Use info to build user stories that complement technical requirements, & help prioritize studies or features
@jointbme @CLEAR_NCSU_UNC 2. Perform early user testing

• Most academics involve users too late
• People often feel they need a good prototype
• But this is a missed opportunity

There are lots of ways to test with and learn from users before you have a complete prototype or formal study protocol.

Want to improve your scientific presentations?

Every great seminar and conference speaker I've seen in my 15 years as an academic researcher did these 10 things. These can 10x your research visibility and impact. And this will unleash new opportunities. 🔥🚀

Let's dive in:
1. Start with something engaging

• Funny story
• Personal anecdote
• Interesting statistic (that the audience doesn't know)

The first thing you say determines whether the audience will be leaning in to listen or picking up their phone to check email. Act accordingly #SciComm
2. Explain the significance

• What's the broader impact on your field?
• What's the future impact on society?
• Why should anyone care?

It doesn't matter if you're presenting to experts in your field or a broad audience. Succinctly and clearly explain why your work matters.

Occupational #wearables for monitoring low back load have potential to improve ergonomic assessments & enable personalized, continuous monitoring of overexertion injury risk in the workplace.
#biomechanics #ergonomics

Encouraged by what we discovered:
mdpi.com/1424-8220/21/2…

1/
We wanted to know: if we can only use a small number of wearable sensors to monitor low back loading, then which sensors should we use, where should we place them, what type of algorithm should we employ, & how accurately can we monitor back loading during material handling?

2/ Experiment overview & workflow using motion lab instrumentat
To address this we synchronously collected data from the #biomechanics lab & from #wearables to analyze 10 individuals each performing 400 different material handling tasks. We explored dozens of candidate solutions that used IMUs on various body locations & pressure insoles.

Four years ago @leonscottmd asked if we could use #wearables to monitor & eventually reduce bone stress injury risks in runners. Based on our latest #biomechanics study I'm more & more convinced answer is going to be: Yes!

What we figured out so far:
authors.elsevier.com/c/1byHRcBxf01UA

1/
Here's a few things to discuss...

#1 what causes overuse injuries like stress fractures?

#2 how do current wearables assess injury risk?

#3 benefits of multi-sensor algorithms

#4 epidemiological evidence from occupational health suggests this approach can work

2/
#1 What causes stress fractures (& other overuse injuries)?

Converging, multidisciplinary evidence indicates overuse injuries are consistent with a mechanical fatigue failure process, in which tissues accumulate microdamage due to repetitive loading. (Fig from Edwards 2018)

Excited to share our new #biomechanics publication on the effect of low-profile elastic #exosuits on back muscle fatigue. #exoskeleton #exosuit

nature.com/articles/s4159…

Challenging experiment, but we learned a lot in the process. Here are the top 4 lessons I took away....

1/ Back-assist exosuit offloads lower back by redirecting some
First, huge kudos to lead author @lamers_erik who completed his PhD last month!

During his time @CREATEatVandy he completed a series of studies on quasi-passive wearable assistive devices spanning from foot prostheses to back-assist exosuits

Super proud of the work he did!

2/
Next some background: When I talk to scientists they often want to know how much exosuits reduce muscle activity, or joint torque, or metabolic rate, or about the optimal assistance levels, specific design features, etc.

And I love this technical aspect of research, but...
