You collected gait data on a child with cerebral palsy (a group of disorders that affect a person’s ability to move and maintain balance and posture). This child recently underwent a tendon transfer surgery but your final computer-animated model did not walk or move as expected. You are suspicious the error is coming from your position data. List 2 sources of error that could contribute to inaccurate position data. You may provide types of error for any motion capture system but state what type of motion capture you are referring to.

Please upload documentation of your methods/work or Matlab code here in PDF file format. Points are awarded here are based on readability, reproducibility, and efficiency. Accuracy of your code is evaluated in question prompts above. If you have more than one file/file type, we’d appreciate if you combined them in to one but an additional file upload box is included below if necessary. 

In this technique, the patient lies within a cylindrical chamber that creates a magnetic field 3,000 to 60,000 times as strong as the earth’s. This technique is called a(n)

Ann performs three different dives and rotates through the same number of revolutions in the same amount of time in all three dives. In all the dives, Ann’s positions at takeoff and just before water entry are identical layout positions. In dive 1 she is in a layout position in midflight. In dive 2 she is in a tuck position in midflight. In dive 3, she is in a pike position in midflight. Select which dive Ann has the smallest mass moment of inertia about the transverse axis (in/out of the page) of rotation.
