If your loved one has LBD, then they have a severe lean to one side. Their head rests on their shoulder and their body tilts heavily in one direction. Whether on the couch or in the car, they lean.
One thing we’ve done to help support her neck is to take one of those head rest things you use on an airplane and use it for her. We had to take a little of the stuffing out where it lies against the back of her neck, but other than that, the sides help support her head. It’s important as the muscles get overstretched if constantly in the heavy tilt position.
So we have two. One for the couch and one for the car. Both destuffed a little but while she isn’t fond of them, they do work better than pillows or other things.
