Abstract:

Objective To investigate the reproducibility and consistency of five⁃repetitionsit⁃to⁃stand test in patients with lumbar degenerative diseases. Methods From January 2019 to May 2020，a total of 63 patients with definite diagnosis of lumbar degenerative disease were selected according to inclusion and exclusion criteria. 5R⁃STS，VAS and ODI were carried out. Paired T⁃test was used to analyze the differences of the two measurements. Interclass correlation coefficients（ICC）were used to analyze the reproducibility of the 5R⁃STS test，and Bland⁃ Altman plot was used to analyze the range of consistency.Pearson correlation was used to analyze the correlation between 5R⁃STS and VAS low back pain，VAS leg pain and ODI score. Results Paired t test showed that the difference between the two repeated measurements was not statistically significant（t = -1.776，P = 0.080 6）. The two repeated measurements showed good consistency，with the correlation coefficient ICC value 0.978 2（95% CI： 0.964 2 ~ 0.986 8，P < 0.05）. 5R⁃STS was positively correlated with VAS low back pain（r = 0.443 8）and ODI （r = 0.660 8）. However，5R⁃STS had no significant correlation with VAS leg pain. Conclusion The 5R⁃STS test could be used as a supplementary measure for functional evaluation in lumbar degenerative diseases，which provides high reproducibility and is consistent with VAS low back pain and ODI score to some extent
