Mascle activity during sit-to-stand
Posted: Tue Jan 30, 2018 7:57 pm
Hello, everyone.
I use OpenSim to examine muscle activity during sit-to-stand movement.
I’ve made some STS motion, but result of SO data is too large than I expected. This picture is result of the muscle activity of soleus_r and ercspn_r. I think these values are too large. I created some models and carried out simulation in the following procedures.
1. I made a motion file from motion capture data. I used Kinect and marker as the motion capture device. To analyze STS motion patterns, I focused on 7 joint angles(ankle_r, ankle_l, knee_r, knee_l, hip_r, hip_l, lumbar_extension) because I acquired these joint angles on sagittal plane in motion capture experiment.
2. I use “gait2392_simbody” as a model. I fixed calcn to the ground using “WeldConstraint” .
3. To examine muscle activity, I did SO from these models.
Do you think there is any problem of my procedures? If I have some mistakes, please tell me where I should change my procedures.
