Parkinson's disease is a movement disorder often characterized by muscle rigidity, tremor, a slowing of physical movement, and in extreme cases, a loss of physical movement.

My mother, who also uses a walker, as you may recall, does this from time to time, too, without being off balance. I attribute it to the PDD, specifically, slow mental processing with, perhaps, some memory loss. I try to read her face when this happens and get a feeling that she may have stopped because she's wondering where she was going. I'll say something to trigger her memory like, for example, "Are you heading to the laundry room?" seeing how she was heading that direction; it may take a couple of seconds and then she'll either just continue to walk to the laundry room or say something to the affirmative and then go there. It doesn't happen that often, but I've noticed it since becoming a more hands-on caregiver on an almost-daily basis in recent months.
My suggestion is to say something to your husband when this happens to help trigger his memory about where he is planning on going, which then should get him oriented and focused again. If that doesn't help, then it may be something else. His neurologist might be of some help and/or, perhaps, others will respond to your posting with their suggestions. When I have some free time later this week or weekend, I'll see if I can find info. about it on-line; if so, I'll pass it along to you here.
