ABSTRACT

Objective The aim of this study was to analyze the effect of gender and age on shoulder and hip range of motion (ROM) and to determine the differences of ROM of normal side shoulder and hip joints between the data we collected and the published standards (Guideline of Examination for Body Impairment in Clinical Forensic Medicine SF/ZJD0103003-2011) in China. Methods We collected cases with unilateral injury of shoulder or hip from clinical forensic medicine. The differences of ROM of normal side joint between the data we collected and the published standards were studied. Descriptive statistics was calculated between male and female subjects in ifve age groups including 0~25, 26~40, 41~50, 51~60 and >60 years, and the ROM changes with age were also studied. Results The data collected in this study was signiifcantly different from the published standard. With age growth, the ROM of shoulder and hip were decreased and a significant difference between genders in partial activity direction of shoulder and hip was found in the individuals who were over 50 years. Conclusion Gender and age appear to be inlfuential factors to determine the normal ROM of the shoulder and hip joint, and there is signiifcantly difference of ROM of normal side shoulder and hip joints between the data we collected and the published standards (Guideline of Examination for Body Impairment in Clinical Forensic Medicine SF/ZJD0103003-2011).
