Your husband's condition sounds similar to mine, when he was discharged from acute rehab unit of the hospital. We continued with physical, speech and occupational therapy home visits through a private agency. Are home visits for therapy an option for you? I found that though the scheduling was erratic for these home visits, it gave us both something to work from.
I don't know about your area, but there is an excellent rehab hospital in Washington DC, National Rehabilitation Hospital that is state of the art in their programs for recovery as well as neurological research. They have a website, and may be able to refer you to an agency in your area.
I tried to help my husband with walking, recommended exercises, etc., but found it difficult to make it a regular practice (I work full time). We posted diagrams of exercises that he could do safely while sitting on the edge of his bed or lying down, on the walls as a reminder so he could do them himself.
I think any effort to keep up the rehab goes a long way to recovery. I have also read that the 1-year window for recovery is too conservative and we should set our sights higher for continued progress. Best of luck to you and your husband.
