Inter-rater reliability between traditional trunk endurance assessment and mDurance.

Variable	ICC (ρ)*	CI 95% of ICC+	Cronbach's α
STEET	0.92	0.68–0.98	0.92
TCSET	0.89	0.59–0.97	0.88
SBET right	0.84	0.39–0.96	0.83
SBET left	0.75	0.06–0.94	0.78

^*ICC (ρ) was calculated using a one-way random model.

⁺ICC indicates the intra-class correlation coefficient.

CI, confidence interval.
