Table 5.

Reliability between three independent observers (interobserver) and one observer scoring three times (intraobserver) using three different scores of hind limb function

Group scored	Stepping score correlation (Cronbach’s alpha)	Coordination score correlation (Cronbach’s alpha)	OFS correlation (Cronbach’s alpha)
Interobserver: chronic non-ambulatory dogs (n = 10)	0.992	0.991	0.997
Interobserver: recovering ambulatory paraparetic dogs (n = 8)	0.991	0.991	0.978
Interobserver: whole group (n = 18)	0.998	0.992	0.997
Intraobserver: (n = 5)	0.997	0.994	1

The dogs were considered as a whole group, but also separated into chronic non-ambulatory and recovering ambulatory paraparetic dogs because the quality of the gait of these two groups of dog is quite different.
