Cincinnati Orthopaedic Disability Index in canines

General description: The Cincinnati Orthopaedic Disability Index (CODI) is a case-specific questionnaire completed by owners of dogs with orthopaedic disease, to measure individual functional status of the dog (Gingerich and Strobel 2003). Owners are asked to describe activities which are restricted in their dog due to the orthopaedic condition and each activity is categorised for severity by the owner.Instructions and scoring: After nomination of the restricted activities, owners are asked to prioritise five activities which they feel are most restricted in the dog. Each activity is rated and scored as either 'no problem' (0), 'a little' (1), 'quite a bit' (2), 'severe' (3 points), or 'impossible' (4) points. The scores are added for all 5 activities with a maximum possible total score of 20 points. Higher scores indicate greater functional restrictions than lower scores. On subsequent assessments, owners are asked to score the previously nominated activities, so that changes in functional restrictions can be monitored over time.Reliability, validity and sensitivity to change: The reliability and validity to change of this outcome measure has not been identified. However, the original paper which reported the CODI found it to be sensitive in detecting change when investigating the effects of a neutraceutical on orthopaedic functional restrictions in dogs (Gingrich and Strobel 2003)
