When using the term "physical therapy" in a sentence, it does not need to be capitalized unless it is at the beginning of a sentence. For example:

- She is going to physical therapy for her knee injury.
- Physical therapy has helped improve his range of motion.

In the first sentence, "physical therapy" is not capitalized because it is in the middle of the sentence. In the second sentence, it is capitalized because it is at the beginning.

Regarding "Mr. Edwards," the "s" does not require an apostrophe. When using the title "Mr." before someone's name, it is not necessary to add an apostrophe before the "s." The apostrophe is only used to indicate possession or as a contraction, not when indicating a title or form of address. Examples:

- Mr. Edwards is coming over for dinner tonight.
- The book on Mr. Edwards' desk is quite interesting.

In the first sentence, "Mr. Edwards" is used as a form of address and does not have an apostrophe. In the second sentence, "Mr. Edwards'" indicates possession, so an apostrophe is added before the "s" to show that the book belongs to Mr. Edwards.
