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

Unit of plot
hi
i have one question about units of results plot of static optimization.
can u tell me what is the unit of result plot of muscle activation and muslce force obtained by static optimization?
thanks

RRA double limb support with only one force plate
hi I have one question. Our lab only has one force plate. When we conducted a walking experiment, we instructed the subject to step on the force plate with their right foot. So we don't have left foot ground reaction force data. In this situation, I think the RRA results are correct in the single li...

Generating muscle weakness patient kinetics and kinematics data from healthy subject's data?
Based on the walking experimental data (trc / GRF / EMG) obtained for healthy subjects, can we create walking data for muscle weakness patients?
