AB For  goniometry  to  provide  meaningful  information,  measurements  must  be  valid.  Validity  is  "the  degree  to  which  a  useful  (meaningful)  interpretation  can  be  inferred  from  a  measurement."1  Stated  in  another  way,  the  validity  of  a  measurement  refers  to  how  well  the  measurement  represents  the  true  value  of  the  variable  of  interest  and  how  well  this  measurement  can  be  used  for  a  specific  purpose.  The  purpose  of  goniometry  is  to  measure  the  angle  created  at  a  joint  by  the  adjacent  bones  of  the  body.  Therefore,  a  valid  goniometric  measurement  is  one  that  represents  the  actual  joint  angle  and  one  that  can  provide  data  for  use  in  clinical  decision-making.  The  joint  angle  obtained  from  a  goniometric  measurement  is  used  to  describe  a  specific  joint  position  or,  if  a  beginning  and  ending  joint  position  are  compared,  a  range  of  motion  (ROM).  In  this  section,  the  four  main  types  of  validity  (face  validity,  content  validity,  criterion-related  validity,  and  construct  validity)  are  discussed  as  they  relate  to  the  measurement  of  joint  motion.
