Inclusion criteria

Original articles

Gait analysis performed with the help of the CW or CW XT

Arthritic disorders as leading component: Studies which made use of the CW or CW XT to evaluate changes of gait in rats or mice of arthritic disorders

Full-text available in English

Data assessment performed at least at two different time points, i.e., preoperatively and postoperatively

Exclusion criteria

Studies evaluating changes of gait related to other causes than defined in the inclusion criteria, e.g., injuries of the peripheral or central nervous system or the vascular system, internal disease (Diabetes) or other musculoskeletal disease than arthritic disorders (e.g., bone cancer pain, fracture)

No gait analysis at all or gait analysis in healthy animals only

Non-rodent models: Studies focusing on animal models other than rodents, e.g., ferrets, monkeys, humans

Review articles, expert opinion, abstract only

Gait analysis was not performed with CW or CW XT: Studies using another gait analysis system than the CW system, e. g. the DigiGait or the TreadScan for evaluation of gait

Complex injury patterns

Intraplantar injection of chemical agents with no direct relation to the joint
