Dad began uncontrollably and repetitively hip thrusting/rocking back and forth non-stop about a week ago. Any ideas?

Dad is 66 with dementia, non-specific, and is in a nursing home. He did break his hip and have a rod put in in January. He also currently has a catheter. These things may have some relevance?

He was fine Wednesday the 22nd of June. I visited him Monday the 27th and for the entire 4 hour visit he was rocking back and forth in his wheelchair. He said he didn't know why he was doing it. I talked to his nurses and they had him lay down and assured me that he stopped doing it when he was laying down. They said they would monitor the situation. This was Monday. Unfortunately, I did not talk to him until Friday as they are short staffed and they don't always answer the phone in his area. We are supposed to have scheduled calls 3 times a week but rarely do they happen.

Anyway, he tells me he is still rocking back and forth and has been even when laying down. I talk to a nurse there and she goes "yeah it looks like he's hip thrusting." What? I thought they were supposed to be monitoring this.

Anyway. Apparently, as of Friday, they were going to have a nurse practitioner and the assistant director of nursing check him out and I still havent heard anything. I talked to the operator and she is relaying my messages. But, I don't know if he's been seen or what.

Basically these symptoms have been happening for a week now.

He is thrusting his hips uncontrollably and when he sits up it makes him rock back and forth but he does it in bed laying down as well. He's not on any new meds to my knowledge. He doesn't have parkinson's, so he's not on any parkinson's meds and to my knowledge that's why people with parkinson's rock, right?

Can it be that he's so stressed that this is his body's way of coping? He really wants to come home :( Or maybe there's an issue with the rod in his hip?

Any ideas at all?

I sit here and wait.

Thank you
