An innovative shoulder ROM measurement device was designed to make measurement of shoulder ROM more easy and reliable. The aim of the study was to report on the comprehensive validity and reliability testing of the new device. The validity of the device compared to the goniometer was found to be strong. Correlation for flexion was0.64 extension was 0.78 and for abduction was 0.73. Cronbachs a for ihtra-rater Reliability for flexion was > 0.5, for extension it was > 0.72 and for abduction il was >0.83.The inter rater reliability for flexion was >0.5.for extension it was>0.63 and for Abduction it was >0.30.According to the statistical analysis, the new shoulder device is a valid and reliable device for measuring shoulder ROM.
