Thank you for understanding the lesson and sharing your assignment; I hope that you will enjoy this week's lesson and try to implement it in your life if you see any such case.

Observations

Task 1 (1.7/3)
You have shared a less knowledge about knee osteoarthritis, even you didn't explain types and stages or grades of knee OA. You need to explain in more depth. I appreciate your effort.

Task 2 (1.7/3)
In the second question, you tell us about how you assess the patient with knee OA by clinical investigation like X ray. But you didn't add the other investigations, physical examination, special tests. Good.

Task 3 (3.8/4)
You try the heel slides, calf & hamstring stretch, William Flexion ( knee to chest exercise), Knee Isometric ( Knee flexion ). If you feel pain behind your thigh or knee back it's mean you have weak muscle due to inactivity try to stay active and perform exercises. Remember always apply heating pad before performing these exercises. I appreciate your efforts.

Overall you made a good attempt to answer all the questions. I appreciate your efforts. But next time try to avoid the above written suggestions. Keep learning and try to implement your knowledge to the people suffering from any knee Osteoarthritis. Thank you.
