I am required to do my 90-day report in person as I left the country. I had an accident fell down with a knee fracture so have very little mobility wearing a splint. How can I request to do my 90 day report online due to my accident? I have continuously been doing it online except I left the country for a trip and the requirement is to do it in person after returning to the country.

AFAIK, "in person" ,means "by a person".  So anybody can do it for you, wife, friend, agent.

Above post is correct. Agent a good option. 

You could do it via mail 15 days prior to due date. 

Some folk state that's incorrect information however I believe that's possible. 

Another option is just to skip doing the report and cop a 2k fine. 

 

Somewhat depends on where you are located.

Such a request does not exist.  Thais do not think outside the box, ever.  So your options are mail, go in person, or have someone else go in person for you.

They will accept mailing in the form? Does anyone have the mailing address?

You can report by mail.

The link posted above gives clear guide and address details. 

When I do Report via, mail to CW., I use 2 B4 envelopes. 

One to send and the other  folded envelop addressed to my residence. 

Don't forget correct stamps as outlined in link. 

Usually they post the approved TM47 receipt along with pp photocopies you sent. 

Note: when you go to post office to send they ask for your pp.
