The above graphs are past measurements of knee motion using previous prototypes.  On the top right is Prototype 1. When it was tested, it was able to function and collect data. That data, however, was relatively noisy, which is why the graph is not very clean. But once we applied a filter in Prototype 2, the values generated a much smoother graph where we can see the distinct times at motion and rest.

CASE STUDY

SUBJECT: Jason Chavez

• 9 Dec 2015: Possibly a partial tear on left knee. He was able to bend the knee but if it was for more than a few seconds past 90 degrees it would start to hurt. Report from the doctor indicated no serious or severe damage to the knee. He got an x-ray beginning of January 2016 and was scheduled for an MRI 01/09/16.
• 8 Jan 2016: Tore the ACL. Played basketball while his knee wasn’t fully recovered from the first minor injury. Caused by some abnormal motion/twisting of the knee. MRI and doctor’s report confirmed that he tore his ACL that weekend.
• 26 Jan 2016: ACL reconstruction surgery on the left knee.​
