Preop, preoperative status; ROM, range of motion; USROM, upper segmental range of motion; LSROM, lower segmental range of motion.
All data are expressed as mean±SD.
*p<0.05. Statistics using paired t test were used to obtain p values for normally distributed data. Wilcoxon signed-rank test was used to assess differences between pairs of data for non-normally distributed data analysis.
