This study evaluated data signatures from an activity monitor of jumps performed by 13 healthy cats that had no evidence of osteoarthritis or degenerative joint disease. Each cat was encouraged to jump up, jump down, or jump horizontally during a 5- to 8-hour observation period. Mean misclassification error rate per cat was 5.4%, which indicates this model is reliable in correctly identifying jumping events in healthy cats. Further studies are expected to show similar results in cats with signs of pain and may be useful in early detection of osteoarthritis and joint pain and in identifying objective end points to assess treatment efficacy.
