Yes, Terri's family was kept in the dark (until ~ 2001) about a bone scan that was done in 1991. Apparently, according to the scan details, Terri "complained" during her physical therapy sessions. She was sent for a scan and it was discovered that she had broken bones all over her body: ribs, pelvic area, and femur among others. It makes one wonder why Terri really collapsed that Feb. night in 1990. Here's the link:

Here's more of Terri's medical record documents. Notice at the bottom of page 2 that the doctor notes that Terri vocalizes in the prone position during physical therapy, and that she says "stop!" to the nurses. Back in 1990!!! That Terri might no longer do this is proof that Michael has neglected her care.

Michael has definitely kept her from receiving the therapy she needs unless we are unaware of recommendations by the therapists and physicians that they had done all they could do.
As for the scan, did they rule out the other possibilities for the results: neoplastic bone disease or multiple bone infarcts from abnormal hemoglobin?
