Possessed Woman Ends Up in Wheelchair

Does anybody remember this supernatural horror film from the late 70's or early 80's?

A family lives in a possessed home, along with their dogs. The wife becomes a victim of evil spirits and in the end her husband is seen pushing her in a wheelchair because she can no longer function from all the evil that happens to her. She looks like she is in shock.

Does anyone have any idea what that movie might have been called?
