Sit-to-stand and stand-to-sit motions are basic motions for daily animal life, and these motions are used as therapeutic exercises for dogs with functional impairments. The sit-to-stand motion is divided into several phases for kinesiological assessment in human rehabilitation and physical therapy. However, these motions in dogs have not been characterized in detail. We examined canine hindlimb kinematic characteristics during sit-to-stand/stand-to-sit motions and compared the characteristics with those during walking. In addition, we tried to classify phases of the movements based on kinematic characteristics of the transition of the range of motion of the hindlimb. We used a three-dimensional motion analysis system to evaluate the motions of eight clinically healthy beagles. During the sit-to-stand motion, the total range of motion (ROM) in the hip joint flexion/extension was half of that of during walking, but the total ROM of the hindlimb external/internal rotation relative to the pelvis and flexion/extension of the stifle and the tarsal joints were significantly larger than those of walking, suggesting that sit-to-stand exercise causes movements of hindlimb joints without marked changes in hip joint flexion/extension movement. Both sit-to-stand and stand-to-sit motions could not be divided into multiple phases only by the transition of the range of motion of the hindlimb.
坐立和站立动作是动物日常生活的基本动作，这些动作也被用作功能障碍犬的治疗性运动。在人类康复和物理治疗中，坐立动作被分为几个阶段进行运动学评估。然而，犬类的这些动作尚未被详细描述。我们检查了犬类后肢在坐立/站立动作过程中的运动学特征，并将其与行走时的特征进行了比较。此外，我们试图根据后肢运动范围变化的运动学特征对运动进行分类。我们使用三维运动分析系统评估了 8 只临床健康比格犬的运动。在坐立动作中，髋关节屈伸的总活动范围（ROM）仅为行走时的一半，但相对于骨盆的后肢外旋/内旋和膝关节及跗关节的屈伸总 ROM 明显大于行走时，这表明坐立运动导致后肢关节运动，而髋关节屈伸运动没有明显变化。坐立和站立动作都不能仅通过后肢运动范围的变化来分为多个阶段。
