Exercise Prosthetic Alignment

Exercises:

In this exercise, we will develop a program to read and plot center of gravity (CG) data from two prosthetic alignment processes.

Device a program to read the CG and Base of Support (BOS) data provided (i.e., patient1.txt and BOS.txt, respectively).

Codes

Results

Use Matlab function(s) to plot the BOS data (hint: rectangle).

Codes

Results

Please add the CG data to the previous figure.

Codes

Results

Please identify and color-code the CG data points outside the BOS range.

Codes

Results

Lets repeat the processes in the previous task with the second data set (i.e., patient2.txt).

Plot the CG data from patient 2. Be sure you color-code the data points outside the BOS range.

Results

Compare the CG data from both patients and determine which alignment was more optimal.

Selection

Rationales

Please suggest one or more existing technologies that can facilitate the prosthetic alignment process.
