Abstract：
This study examined the percentage and location of trigger points in police working dogs. Twelve dogs housed at a military police kennel were selected through convenience sampling. Only active dogs with no comorbidities or radiographic changes doing 6 hours of intense physical activity per day were included. After orthopedic and neurological examination, dogs were palpated for the detection of trigger points (TPs), carried out by two independent examiners, with criteria of palpations previously standardized. TPs were recorded using an anatomy reference image according to the corresponding anatomical location. The percentage of TPs was highest in the lumbar portion of the longissimus dorsi muscle (42%), followed by the latissimus dorsi, pectineus, quadriceps femoris, and sartorius (33%) muscles. Most TPs were located on the right side of the body. This study\'s percentage of TPs in police working dogs was higher in spinal and hind limb muscles, especially on the right side. The major criteria for identifying TPs in dogs were the pain responses to palpation and contractile local response. The findings of this study could be used to refine myofascial pain prevention to reduce early retirement due to musculoskeletal pain and draw attention to this kind of problem that can also affect dogs.
摘要：
这项研究检查了警察工作犬中触发点的百分比和位置。通过便利抽样选择了十二只饲养在宪兵狗窝中的狗。仅包括没有合并症或放射学变化的活跃狗，每天进行6小时的剧烈体力活动。经过骨科和神经系统检查，对狗进行触诊以检测触发点（TP），由两名独立考官进行，具有先前标准化的触诊标准。根据相应的解剖位置使用解剖参考图像记录TP。TP的百分比在背最长肌的腰椎部分中最高（42％），紧随其后的是背阔肌，果胶,股四头肌,和缝匠(33%)肌肉。大多数TP位于身体的右侧。这项研究的警察工作犬中的TP百分比在脊髓和后肢肌肉中更高，尤其是在右边。在狗中鉴定TP的主要标准是对触诊的疼痛反应和收缩局部反应。这项研究的结果可用于改善肌筋膜疼痛的预防，以减少由于肌肉骨骼疼痛而导致的提前退休，并引起人们对这种也可能影响狗的问题的关注。
