Due to COVID-19, laboratory and hospital closure halted the trial until January 2021. Since that time, the researchers have not had owners with appropriate cases agree to enroll in the study. Major sources of cases are athletic dogs such as agility dogs. Due to COVID-19, agility and other trials were halted. When starting back up in late Spring/early summer of 2021; the formerly busy caseload for supraspinatus tendinopathy has not yet returned. The researchers anticipated a lag between the beginning of agility trials and injury to the canine athlete’s shoulders, however, within the last 24 months, that has not proven to be the case.
Due to the many delays, and the much lower than expected caseload, the researchers and their organization determined to withdraw the clinical trial for supraspinatus tendinopathy. The research team will continue to monitor any future cases of supraspinatus tendinopathy to determine if a future study is warranted. The investigators appreciate the trust of the donors who support this study and the research of musculoskeletal conditions and disease of dogs in the future through the AKC Canine Health Foundation.
