iam confused about this......epoch with major body movement , not associated with alpha rhythm ,not preceded or followed by waking epoch...this epoch will be scored as the epoch following it ...
but what about the movement??... will be scored arousal ???

Movement is not scored on its own. If no arousal, then no arousal. But otherwise, movements are not tagged according to the new rules. No more "MT" Movement Time.

J. Scoring Epochs with Major Body Movements
1. Score in accordance with the following definition:

Major body movement: Movement and muscle artifact obscuring the EEG for more than half an epoch to the extent that the sleep stage cannot be determined.
2. If alpha rhythm is present for part of the epoch (even <15 seconds duration), score as stage W.
3. If no alpha rhythm is discernible, but an epoch scoreable as stage W either precedes or follows the epoch with a major body movement, score as stage W.
4. Otherwise, score the epoch as the same stage as the epoch that follows it.

For minor body movement I add:
Does EMG increase? If it does it may change stage if in REM.
