There are 2 topics to choose from this week, there should only be 2 total Discussion threads.
Only ONE (1) very long thread for each:
Functional Activity
Range of Motion
What then follows the beginning of each thread is a great discussion.
If there is a thread that is already started, please do not start another one on the same topic.
Thank you for your attention to this.
