Single, periodic reflex modulation in 1 of the antagonistic muscle groups only; Recip. or Synch., periodic reflex modulation occurring concomitantly in pairs of related muscle groups with reciprocal (Recip.) or synchronous (Synch.) relationship; Fluct., fluctuation between reciprocal and synchronous modulation; x, pattern present.
