of spinal core stability is supposed to be one of the
important predisposing causes of recurrent low back pain
(LBP)1). As a result, more attention has been paid to training
of localized spinal stabilizer muscles in subjects with
LBP2). It is believed that specific stabilization exercises lead
to changes in motor programing of the automatic feed-forward
recruitment of deep core muscles3). Therefore, stabilization
exercises were suggested for chronic low back pain
(CLBP) patients4–7).
Recently, it has been reported that the use of stabilization
exercises can improve the multifidus (MF) muscle size in acute LBP
