This was part of a larger goal to create a digital twin for a robotic spine simulator "TIM" we are developing — a hands-on benchtop test bed to visualize and understand spinal mechanics interactively.

Siril Dukkipati @biomech.siril.me · May 20

Key highlights:

Two novel methods to represent IAP in rigid body dynamics

Inclusion of nonlinear ligament, muscle, and disc behaviors

Model validated against in vivo, ex vivo, and in silico datasets

Open-source MATLAB implementation for broader accessibility

This model compiles in seconds, simulates in just over a second, and could be a powerful simulation platform for real-time applications, like robotic spine simulators or reinforcement learning frameworks for posture control.

In this work, we developed a computationally lightweight spine model in MATLAB that doesn't just simulate musculoskeletal mechanics but also integrates intra-abdominal pressure (IAP) to reflect spinal load-sharing more accurately during everyday movements.

Thrilled to share that my latest research has been published in IEEE Transactions on Biomedical Engineering!

It would have been a worthwhile debate. Peer review vs. IP

I think there's not need to blur out the journal name. These for-profit syndicates need to be held accountable for this behavior.

Siril Dukkipati @biomech.siril.me · Feb 23

Highlights:

1. Open-source: anyone can print these models and use them for spine testing. Or buy from us and support the research @ simcare.tech

2. Fully 3D printable

3. Stiffness tunable to patient biomechanics

4. Cheap

Can analogue spine models behave physiologically?

We recently published 2 papers on this. They report our analogue spine's mechanical behaviour similar to living spines which we use to corroborate our in silico spine models and test spine implants in a controlled and validated environment.

L3-L4 fusion simulation on a lumbar spine phantom. We wanted to see if our 3D printed phantom could realistically simulate range of motion compensation in adjacent levels when fused. Results to come. #spine #biomechsky #biomechanics #mdsim #mcgill

Today is the last day of classes for the "Intro to #MSK #biomechanics" course I'm teaching this semester. This has been such a privileged and rewarding experience for me. Got to #teach a very bright bunch of students. Looking forward to many more of these.!

This is pretty awesome 👏🏻👏🏻. The contact mech looks very realistic. Is there an RL agent underneath for muscle recruitment? Or some sort of optimization to be run for each task?
Any plans to introduce flexible bodies? We are building a similar model focused on spine and speed. bsky.app/profile/biom...

Siril Dukkipati @biomech.siril.me · Nov 19

I'm also interested in modeling muscle recruitment, particularly in spinal stabilization. Recently, we built a high-fidelity digital twin of this human torso, from scratch...with integrated flexible bodies, and the runtime is just under 10 secs!

Doing some HIL testing with actual hardware in Dec.

This is amazing to see. Thank you for taking the initiative @sheynlab.bsky.social. Let's hope the group keeps getting bigger.

I’d love to connect with fellow #spine researchers and #biomechanics enthusiasts here! Let’s chat science—feel free to send me a follow request.

Siril Dukkipati @biomech.siril.me · Nov 19

These posts are just a glimpse of my full thesis—there’s much more to it, with even more to come. I'll update here as we go.

I've also been teaching a graduate course, "MECH 561 - Intro to MSK Biomechanics" these past two semesters and have been really enjoying the teaching side of things.

Something I've been recently interested in and is the natural next phase of the above model - introducing #IVD stiffness tuning and nonlinearly to be able to represent level-by-level stiffness variability and in a population.

The solution might be lattices!

Just got here from the other side, so I thought I'd give an intro.

I'm a PhD candidate working with Dr. Mark Driscoll at McGill University, studying #spine #biomechanics, building 3D printed spine phantoms, muscles, and robotic benchtops of the human spine.
