the trunk pelvis hip angle test is a reliable measurement of the range of the lower trunk pelvis rotation in adolescents

1. Abstract 1.1. Introduction: Rotational movements of the trunk and pelvis are visible during activities of daily living. To date, no researchers have assessed the reliability of any test used to examine rotational mobility of the  lower trunk-pelvis  complex. The aim of the study was to assess the reliability of the  Trunk-Pelvis-Hip Angle  test. 1.2. Materials and Methods:  The study included healthy 41 adolescents aged 12-15 .  Measurements were performed by three experienced physiotherapists. 1.3. Results:  Reliability was excellent for three observers. Intraclass correlation coefficient ranged  from 0.894 to 0.938 for intraobserver reliability. The interobserver intraclass correlation coefficient ranged from 0.888 to 0.900 . 1.4. Conclusion: The Trunk-Pelvis-Hip Angle test is a reliable measurement and may be used for examining the range of the lower trunk-pelvis rotation in adolescents. The test provides a new possibility in diagnosing the musculoskeletal system. 2. Keywords:  Adolescents; Pelvis; Range of Rotation; Reliability; Spine; Trunk 3.
