Something about your model. #7

Hello Sepehr, I am now trying to measure my upper limb muscle parameters, and I find there are loads of methods. At this moment of hesitation, I found your model code in Github, and I wonder how to use this model to estimate my parameters of the upper limb, like the biceps. What kind of data is needed of my arm in this model? And is there any instruction letter or paper about parameters estimation?

Thanks, Yanfeng

Hi Yanfeng, I can help you more if you describe what parameters are you going to estimate or measure. if you are talking about protocols it's highly depends on your study and your goal. My study currently is on the lower limb and my model does not support upper muscles. Best, Sepehr

Hi Sepehr, Thanks for your kindly reply. Actually, I want to estimate some parameters (like the maximum isometric muscle force, Optimal fiber length, non-linear shape factor A, ...) of the Hill-based musculoskeletal model. The muscle group I want to adopt in my experiment is the agonist and antagonist muscles of wrest, like the Biceps and Triceps. The sensors that our lab has are a surface EMG device and an ATI 6D force sensor. Is there any possibility to obtain those wanted parameters with the sensors we have?

Sincerely, Yanfeng

You need to think a bout feasibility of your problem. It seems you don't have kinematic of your system which makes your problem difficult. You need IK data to calculate moment arm of your muscles and other geometry related parameter like muscle length. I would say if you try to run Isometric task and measure joints angle with manual goniometer and feed it to the model probably you can do some thing.
