Fig. 4From: Assessment of net knee moment-angle characteristics by instrumented hand-held dynamometry in children with spastic cerebral palsy and typically developing childrenBland and Altman plot for knee angles at 4 Nm. Net knee moment at day one and day two (between-day) (●) and session one and session two (within-day) (○). X-axis: mean values of day one and day two measurements as well as mean values of session one and session two. Y axis: difference between the knee angles (day one minus day two as well as session one minus session two). Dotted line: smallest detectable difference (SDD) of the between day reliability. Dashed line: SDD of the within-day reliabilityBack to article page
