Bedo model

Hi Thank you so much for providing your amazing model. i have three questions. first, I'm curious about what the RLAS and LLAS marker are. are these markers marker's on iliac crest? second, I'm trying to implement the sit-to-stand motion, stair ascending and descending on your bedo model. I know tha...

bedo model and marker edit (sit to stand)

Hi i need some help The marker set used in our lab consists of 38 markers, and the bedo model I want to use consists of 45 markers. I have some questions here. 1. Our lab's marker set is fewer than the 45 marker sets of the bedo model, at 38. If we modify the marker set of the bedo model to our lab'...

Problem in openning model

Hi i use "Examining Muscle Forces during Sit to Stand Transfer with Full Body Model 2016" model to analysis muscle force during sit to stand movement. when i opened the model, it's skeleton looks weird below, even i tried 'show' the right side humeus in this model but it didn't work. is it graphical...

Sit to stand model openning error

Hi i use "Examining Muscle Forces during Sit to Stand Transfer with Full Body Model 2016" model to analysis muscle force during sit to stand movement. To use this model, i opened .osim file of model, but there's an error message below. So i corrected 'rotational' to 'coupled' of coordinates in this ...

Sit to stand one force plate

hi I have one question I want to analyze the angle, moment, joint contact force, and muscle activation of the ankle and knee joints for sit-to-stand and stand-to-sit movements. Since our lab only has one force plate, I think we can't perform CMC through RRA. So I'm planning to perform SO (static opt...

Predict left foot GRF

hi Our lab has a motion capture system, emgs and only one ground reaction plate. We experiment with movements such as walking down and up stairs, walking down and up an incline, walking on level ground, sitting and standing, and standing and sitting. For walking experiments, subjects were instructed...

CMC vs RRA vs SO

hi I have a question. As I know, Result of RRA: excitation for each joint, Result of CMC: excitation for each muscle, Result of Static optimization: excitation for each muscle. Here, the results of CMC and SO are the same(excitation of muscles), but CMC produces excitation of muscles as a result aft...

one force plate during sit to stand and gait experiments

hi I want to analyze muscle activity and joint moments from sitting to standing and gait seperately. There is only one force plate in our lab. During the sit to stand experiment, only the right foot was placed on the force plate and only the right foot stepped on the force plate during gait experime...

Re: Subtalar joint in gait2354 model

Hi mohammadreza thanks for your reply. I will proceed according to your answer. I have one question. Regarding the marker weight and coordinate weight in the picture below, the marker weight seems to be weighted to follow the trajectory of the marker more appropriately, but if you enter a large numb...

Subtalar joint in gait2354 model

hi
I have motion capture data for walking and sit to stand movements.
However, when this data is entered into the gait2354 model, the subtalar joint does not move.
I would like to analyze the ROM, moment, and contact force of the subtalar joint. How can I do this?
I need help
thank you
