The aim of this study was to evaluate the effect of interferential current therapy on ground reaction force and orthopedic assessment score of canine patients with hip osteoarthritis. Nine dogs that met the inclusion criteria were enrolled in this study. Each dog received 3 types of treatment: interferential current therapy (IFC), sham current therapy (SHAM), and control treatment (CTR). The order of the treatments for each dog was assigned by block randomization method. A 24-hour interval was applied between each treatment session. Subjective orthopedic assessment and objective force plate gait analysis were used as measurement of clinical improvement in this study. Lameness, articular mobility and articular pain scores as well as peak vertical force (PVF) variables were assessed prior to and post treatments. Statistical analyses revealed significant increase in PVF of the IFC group (p<0.05). There was a significant decrease in PVF in the CTR group (p<0.05). In the SHAM group, there was no significant change in PVF. There were no significant changes detected in the lameness, articular mobility and articular pain scores. Post hoc comparisons using Tukey-Kramer test demonstrated that the IFC treatment was significantly more effective than the SHAM and CTR treatments (p<0.05). The significant improvement in PVF of the dogs with hip osteoarthritis may be associated with pain alleviation effect of the IFC treatment. The results of this study suggest that IFC may be useful for the treatment of canine osteoarthritis
