,questioner and check list were utilized. Totally 423 samples by proportional cluster sampling

method collected and we used spss15 soft ware for statistical analysis

Results

The results of this investigation demonstrated that maximum mean value of OCRA index in left and right hands were related to shatery task in sangak bakery (OCRAI index=14.99).finally,56.5,67.4,77.3 and 75 percent of all tasks at Tafton davar,Tafton sonnati,

sangak and baget bakeries respectively were in the red area also our results showed that only ,left and right hands OCRA index means of nandari , forushandegi and nandara/forushandegi tasks were equivalent.
