Abstract
Objective: To evaluate the impact of postoperative swimming therapy on hind limb functional recovery in dogs following femoral head and neck excision (FHNE) using the symmetry index (SI) of peak vertical force (PVF) data from ground reaction force measurements and orthopedic evaluations.
Methods: From February 18, 2021, through February 18, 2023, dogs undergoing FHNE were randomized to swimming and nonswimming therapy groups. Hind limb PVF and an orthopedic assessment score were recorded at 1, 2, 3, 4, 5, 6, 9, and 12 months postoperatively. Time to functional recovery, defined as the period needed for a dog to regain use of the operated limb and determined by the SI of PVF, and lameness score of orthopedic assessment score were analyzed using Kaplan-Meier estimation and compared between groups using the log-rank test.
Results: The data from 27 dogs were analyzed: 12 in the swimming and 15 in the nonswimming groups. The swimming group demonstrated a faster median functional recovery time as determined by the SI of PVF at 3 months, compared to the nonswimming group median functional recovery time at 6 months postoperatively. Based on lameness scores during trotting, the operated limb achieved functional equivalence with the nonoperated limb by 3 months in the swimming group and by 5 months in the nonswimming group.
Conclusions: Swimming therapy accelerates functional recovery and facilitates a faster return to normal hind limb function in dogs after FHNE.
Clinical relevance: This study supports the use of swimming therapy following FHNE, potentially reducing recovery time and improving outcomes when used alongside other therapeutic techniques.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
