Quality-of-outcome measures were documented in the discharge report at the beginning (t1) and at the end (t2) of the 21-day inpatient rehabilitation program. The PROMs consisted of Oswestry Disability Index (ODI), Numeric Pain Rating Scale (NPRS), the Health Assessment Questionnaire Disability Index (HAQ-DI) and the Five-Level EuroQol-5D (EQ5D-5L). The CROM was the Fingertip-to-Floor test (FTF), where the optimal value in this study has been defined as 0 [cm]. Differences between those measurements (difference: t2-t1) and effect sizes (Cohen’s dz) were used to evaluate recovery in rehabilitation. The level of statistical significance was reached for all outcome measures (all p < 0.001***; ηp2 multivariate = 0.490)
