Good idea: soundwaves that change material stiffness

https://techxplore.com/news/2026-03-remotely-reprogram-material-stiffness-implants.html

A team of researchers co-led by the University of California San Diego, University of Michigan, and the French National Center for Scientific Research (CNRS) at Laboratory of Acoustics of Le Mans University has demonstrated a new way to remotely control how a material behaves—using sound. The findings could lead to the development of protective gear, robotic muscles or medical implants that adjust their stiffness on demand.

A post stretch report on a not-so-good day

Original post:

This is my post-stretch report on a not-so-good day. I woke up extremely stiff and in pain. Time to do those stretches I learned about in Bath.

Here’s my #WorkOut report.

Shoulder rolls

• Rolling shoulders forward, up, and back.

Some relief for my neck and shoulders.

Neck flex and extend

• Moving head over to the side. Then the other.
• Head forward, then back.
• Twisting neck by looking left and then right.

More head and neck stiffness relief. Slightly less head pain.

Seated flexes and twists

• Twisting body clockwise and then counterclockwise while seated.
• Hip flex by side leaning.

Some back tension relief. Starting to feel human again.

Chest and shoulder

This one is harder to explain. hands out face up with elbows at a right angle. Move hands in a circular motion outwards. This opens up the chest and flexes the shoulders taking tension from the neck as it does so.

Overall

I feel somewhat better. Head hurts less. Back and shoulders feel freer as the stiffness is lower.

I should really do this more often.

Why Mobility Work is a Great Recovery Tool 🛠️

Mobility work is any form of exercise or movement designed to improve the functional range of motion in your joints.

🩸Improves Blood Flow and Nutrient Delivery

📉 Reduces Stiffness and Soreness

🦵 Maintains Joint Health and Range of Motion

🔄 Supports Better Movement Mechanics

Happy Christmas, I guess

I’m awake early, not because of excitement; I’m low-key dreading today. No, I am awake because today is a pain day. I’m hoping the waking stiffness lifts.

In unrelated news, I went to the NASS website thinking I’d use the shop to replace my good/okay/bad day wrist bands. Shop is gone. Found some wholesalers but not sure if I want to buy/sell that many bands just to get mine.

Is that a good idea?

Anyway, Happy Christmas, I guess.

For those who struggle with back pain. Take a look and learn why.
This was an enlightening education. A deep dive into why peoples suffer back pain or back stiffness and why people seem to not being able to correct the issue.
I think he brought up very good points and helpful tools to treat the problem instead of managing the symptoms that only work for a while. There is proper solutions and demonstrations of what to do and how to do it as well as why you must do them. If you understand the reasons why, you'll likely be more eager to follow through with the treatment. Correcting muscle imbalance seem to be the solution to most problems, even that of flexibility and nervous system challenges. Anyway, the video was an hour long but well worth the time if you want to educate yourself on this topic, the best explanation and solution I've come across so far.

Oh and he is the only person I've come across who understand what the core muscles consists of. Your "barrel" core muscles (Obliques, Transvers, Abdominal, Pelvic floor, Diaphragm) but also the often overlooked spinal core muscles (Spinal Erector, Quadratus Lumborum, Psoas), together they are essential to keep your back, your lower back strong and healthy. And he make a point of actually strengthen them, especially the spinal core muscles, which he complain most of the therapists neglect.
