Think this is my 1st time commenting on this case, but been reading for a long time!
Yes, it's quite easy to fully restraint yourself, including rendering yourself completely immobile, and you don't need anything fancy. You have probably seen cases (often times stars) where they die from something self-inflicted and "kinky".
If I recall correctly, they said she was not "cut" but had "burns" which says to me the brand is a burn and not something carved into her. Brands that are burned into someone, often heal very oddly and can partially scar or not scar at all in some spots. If picked at or an ointment is used the skin is less likely to bubble up and such. People who get brands done as body modifications often struggle with even healing. I BELIEVE that Caucasian skin leaves less of a scar then people who are darker. Unless she also had burns on her hands I cannot imagine HOW she would have burned her own shoulder, which is just one of the reasons why I don't feel this is a hoax.
The hose clamps on her ankles would have been quite tight as they were for "compliance". This generally means they are tightened to the point that a person is pretty much forced to tip toe as the Achilles tendon is pushed in. I have no clue how long she had these on for or how tight they were, but they would have definitely cut into her skin and depending on the time would have probably left some scars and raw skin under them, especially after adrenaline kicked in and she was free to run. It's so hard to tell if she is running on flat feet or tip toed, but at that point if survival was the only thing on her mind, that pain wouldn't have stopped her from running. (You see women run in HIGH heels all the time).
All JMO
