Validity of the Wii Balance Board for Evaluation of Medial Patellar Luxation in Small Sized Dog

다국어 초록 (Multilingual Abstract)

Wii® balance board (WBB) is a device that can measure and record body sway. This study was conducted to evaluate the reliability of WBB in small sized dog as inexpensive, portable and convenient tool. The center of pressure path length (CPPL) and 95% confidence ellipse area (Area 95) were evaluated with only two plates of WBB.
The parameters were evaluated between no load (0 kg) and mass group (0.25-4 kg on each one plate). 23 dogs (2.3- 7.3 kg) were evaluated for with hindlimb standing for 10 seconds. The mass group showed a significant value in comparison to the no load during the measurement. And intra-class correlation coefficients (ICCs) between CPPL and Area 95 revealed very high both mass and dog group. In the evaluation of medial patellar luxation (MPL) as a diagnostic tool, 80 dogs with MPL and 23 non-affected dogs were used. In studies of CPPL and Area 95, significant differences were found between non-affected and MPL groups for 10 and 30 seconds, respectively. The WBB can be used as a valid tool for evaluating hind limb standing balance and can be useful as an objective tool to present clinical results in small sized dog with MPL.
