Poor traction on slick surfaces is difficult for dogs with neurologic deficits, osteoarthritis, or recovering from injury or surgery. Many dogs respond inappropriately to slick surfaces by decreasing digital pad-floor contact and extending their toenails. A device marketed to increase paw-floor friction in dogs was evaluated. Fifteen normal dogs underwent kinetic gait analysis before and after application of Dr. Buzby's ToeGrips. Ground reaction forces, including vertical peak force (VPF) and impulse for each limb, were measured and compared between pre- and post-application values. Stance time was significantly increased in all limbs after toe grip application. Stride velocity was slower in all limbs but significantly slower only in the left forelimb. VPF was significantly deceased in both hindlimbs after toe grip application, but the decrease was within the group SDs. Vertical impulse was significantly increased in both forelimbs and in the right hindlimb. Dr. Buzby's ToeGrips result in a slower gait, with slightly decreased VPF in the hindlimbs and increased effort for propulsion kinetic changes were of minor magnitude and unlikely to be clinically relevant.
对于患有神经功能缺损、骨关节炎或正在从损伤或手术中恢复的狗狗来说，在光滑表面上行走时难以获得良好的抓地力。许多狗狗在光滑表面上会做出不适当的反应，减少趾垫与地面的接触并伸出它们的爪子。对一种旨在增加狗狗爪子与地面摩擦力的装置进行了评估。15只正常狗狗在使用布兹比博士的趾套前后接受了动力学步态分析。测量并比较了使用趾套前后包括垂直峰值力（VPF）和每个肢体的冲量在内的地面反作用力。使用趾套后，所有肢体的站立时间均显著增加。所有肢体的步速都较慢，但仅左前肢的步速显著减慢。使用趾套后，两个后肢的VPF显著降低，但降低幅度在组标准差范围内。两个前肢和右后肢的垂直冲量显著增加。布兹比博士的趾套导致步态变慢，后肢的VPF略有降低，推进力增加，动力学变化幅度较小，不太可能具有临床相关性。
