Study Design: Cross-sectional study. OBJECTIVE: To compare reliability of shoulder internal rotation (IR) passive range of motion measurements in supine and side-lying position. Background: Intrarater reliability for measuring shoulder IR has been found to be excellent. Interrater reliability for measuring shoulder external rotation has always been good but interrater reliability for measuring shoulder IR has been poor or fair. Side-lying position which is similar to sleeper stretch position has been reported to give better reliability for measuring IR. However, there is need of more evidence to support this hypothesis. Also there is need for more objective data for normative values in this position on both dominant and non-dominant side. Methods: 200 asymptomatic subjects, 108 females and 92 males with mean age 22.24years were included in the study. Shoulder IR passive range of motion (PROM) of dominant and non-dominant side was measured by two physical therapists in both supine and side-lying position. For interrater reliability, each rater obtained 2 PROM measurements on the same day. For intrarater reliability, two PROM measurements were measured after 48 hours again by primary investigator (rater 1) in both positions. Results: Intrarater reliability in supine and side-lying positions was excellent for dominant and non-dominant shoulder IR with ICC ranging from 0.950 to 0.970. Interrater reliability in supine position for dominant shoulder IR was good (ICC= 0.853) and for non-dominant was fair (ICC= 0.775). Interrater reliability in side-lying position for dominant and non-dominant shoulder IR was excellent, ICC= 0.946 and 0.924 respectively. The mean side-lying IR ROM value for dominant shoulder was 61.06˚ ± 9.64˚ and non-dominant shoulder was 69.56˚ ± 9.50˚ and average supine IR ROM value for dominant shoulder was 91.63˚ ± 10.28˚ and non-dominant shoulder was 99.44˚ ± 10.06˚. Conclusion: Intrarater and interrater reliability of shoulder IR measurements in side-lying position was superior compared to that in standard supine position.
