  • *For baseline differences between intervention groups, χ2 test was used in case of categorical variables and F-test (ANOVA) in case of continuous variables.

  • †For differences within intervention groups between participants who completed all follow-up assessments and those who dropped out of the study, χ2 test was used in case of categorical variables and t-test in case of continuous variables (corrected for unequal variances where applicable).

  • ANOVA, analysis of variance; NHV-E, early rehabilitation group; NHV-L, late rehabilitation group; SCI, spinal cord injury; TBI, traumatic brain injury.
