3) Gait Analysis (25 points) For this question you are going to work with gait_final.xlsx and gait_final.munx files. Please answer the following questions, relying on the data provided to you. 1) What is a gait analysis? (0.5 points) 2) What is a gait cycle? (0.5 points) 3) How many right gait cycles are present in the recorded data? (0.5 points) 4) How many left gait cycles are present in the recorded data? (0.5 points) 5) What is the stride time for each gait cycles? Show your calculation. (3 points) 6) Plot five different joint angles for right gait cycles? (1 points) 7) Plot the same five different joint angles for left gait cycles? (1 points) 8) Plot the normalized version of step 6 (1 points) 9) Plot the normalized version of step 7 (1 points) 10) Are there any diffences between the joints angles that you plotted for left and right gait cycles, just make a visual check, and explain. (1 points) 11) Calculate the percentage of stance and swing phases for left and right gait cycles. Are they consistent with lecture notes?(3 points) 12) What are the peak values of right knee flexion/extension during stance phases for each right gait cycles. (2 points) 13) How the COM is changing while the subject is walking, try to explain that change? (2 points) 14) What is the cadence for this recording? (2 points) 15) Calculate the percentage for loading response" for right gait cycles, are they consistent with the lecture notes? (3 points) 16) Calculate the percentage of "single limb support" for right gait cycles, are they consistent with the lecture notes? (3 points) Show your all calculations as a report, explain each step one by one, you can use excel or matlab for your calculations. Do not write codes that are irrelevant, only write the codes which are necessary. I will directly copy/paste your codes to matlab platform. If it's not working, your question is not going to be evaluated. So when you're writing and explanation, please write them as comments with % signs
