For as methodical, logical and evidence driven Dr. Brennan is, she made some major assumptions in this episode. I can accept evidence of De Quervane's Tenosinovitis(?) markers on the bones but she assumed the victim was in too much pain to have played the record-setting game. The only one who could have told her what his pain level was was a pile of bones on her table. She assumed he didn't have the range of motion to have played the game. Since tendons are soft tissue (out of her area of expertise) she couldn't have known by examining the bones. Also, range of motion decreases as the condition worsens, so she also assumed the length of time he suffered from it. And last, she assumed he didn't have the surgery and subsequent physical therapy to restore range of motion, Yes, she could have spoken to his doctor but that's doubtful because the doctor would have cited HIPAA laws to keep the information confidential. For a character that's as evidence driven as Dr. Brennan, she drew conclusions that had little to no evidence backing them.
As a side note, I know this because I suffer from De Quervane's.
