Abbreviations: a: Results of Bonferroni Post Hoc tests in the CFT group; b: Results of Bonferroni Post Hoc tests in the MSI group; CI, Confidence Interval; NRS: numeric rating scale; NA, Not applicable; ODI: Oswestry Disability index; TSK: Tampa Scale of Kinesiophobia; ↓ decrease, ↑ increase; †, Effect size (Cohen’s d).
All calculations were done using intention-to-treat principles. Two-way repeated-measures analysis of variance (group × time) was used to compare differences between two groups based on adjusted analysis.
