Do sleep walkers still get the same, sufficient amount of recuperation as if they slept soundly?

After watching the reaction video of the mother who was treated to a video of herself sleepwalking (for what I assume is the first time), I was curious if the brain can still recuperate as efficiently when someone is sleepwalking as if they had slept soundly.

No, sleep walkers generally walk during the SWS (slow wave sleep) phase of rest and require a higher level of consciousness than is typically seen during REM (rapid eye movement) because their brain is partially engaged during the walk.

But, this varies depending on the complexity and length of the sleep walk.  Sleep walking can be as short lived as 30 seconds or as lengthy as 30 minutes.  

Given a sleepwalker with a complex walk (such as walking about the house and re-arranging things) and lengthy walk (30 minutes), their brain may miss the benefits of an entire REM cycle and feel as if they have slept for 1.5 hours less than a non-walker.  

On the opposite end of the spectrum, a sleep walker that sits up on their bed for 30 seconds may not feel any different than any other non-walking night.

So, the answer is no sleepwalkers do not get the same amount of rest as compared to a night where they sleep soundly, but it really depends.

**Edit**: Misread the question.

**Edit 2**: Yes, there are no empirical facts here but it is well-understood that a lengthy interruption of REM sleep (being the most vital cycle in feeling well-rested) will cause the individual to feel lethargic the next day.  This can safely be inferred.  But, as to some of the shorter sleep walks it would be scientifically responsible to map the brain waves of the sleepwalker and determine if the short walks cause enough interruption to interfere with sleep cycles in any meaningful way.

The point is, lengthy sleep walks are very likely to cause the sleepwalker to feel the effects of the interrupted sleep the next day.
