AB Congenital  muscular  torticollis  (CMT)  is  a  common  postural  asymmetry  of  the  neck  affecting  3.9%  (Aarnivala,  Valkama,  &  Pirttiniemi,  2014;  Chen,  Chang,  Hsieh,  Yen,  &  Chen,  2005)  to  16%  (Stellwagen,  Hubbard,  Chambers,  &  Jones,  2008)  of  newborns.  It  results  from  unilateral  shortening  of  the  sternocleidomastoid  muscle  (SCM)  and  is  typically  characterized  by  ipsilateral  cervical  lateral  flexion  and  contralateral  cervical  rotation  (Do,  2006).  Screening  for  nonmuscular  causes  of  the  asymmetry  is  essential  because  the  asymmetrical  neck  posture  in  up  to  18%  of  infants  results  from  nonmuscular  causes,  including  skeletal,  neurological,  and  visual  conditions  (Ballock  &  Song,  1996).  It  is  also  important  to  screen  infants  for  conditions  associated  with  CMT  because  craniofacial  asymmetry  is  a  coexisting  impairment  in  up  to  90%  of  infants  with  CMT  (Cheng,  Tang,  Chen,  Wong,  &  Wong,  2000).  Other  associated  impairments  include  developmental  dysplasia  of  the  hip  (DDH)  (Tien,  Su,  Lin,  &  Lin,  2001),  perinatal  brachial  plexus  palsy  (Ballock  &  Song,  1996),  and  foot  deformities  (Cheng  et  al.,  2000).
