My husband could not speak for months and he was also in a geri chair. I continued to sit beside him and stroke his arms and his hair. He loved for his hair to be rubbed. I would sit close and remind him of old memories and stories. Sometimes he could respond by wiggling his eyebrows. We had always loved to dance, so I would put on old Sinatra songs or New York, New York. Then I would take his hand and gently move to the music. We read poetry and stories. Music was always playing softly in the room. Like Krwcna said, back rubs are good. He lost a lot of weight, but reminded content for many months until he actually passed. Even when their eyes are not open or they seem not to respond, I feel that they can hear and feel.
