Trigger points (TP) are objectively demonstrable foci in muscles. They are painful on compression and trigger pain in a referred area. This area may be the only locus of complaint in humans. In dogs we cannot prove the existence of referred zones of pain. Therefore, we can only diagnose a TP-induced claudication if we cannot find bone, joint, or neurologic abnormalities, and we do find TP that disappear after treatment together with the original lameness. Several methods have been developed to demonstrate TP existence objectively. These are pressure algometry, pressure threshold measurements, magnetic resonance thermography, and histology. In humans, 71% of the TP described are acupuncture points. TP treatment consists of TP stimulation with non-invasive or invasive methods such as dry needling or injections. In the dog, ten TP are described in two categories of clinical patients. First, those with one or few TP reacting favorably on treatment (+/- 80% success in +/- 2-3 weeks). Second, those with many TPs reacting badly on treatment. Most probably the latter group are fibromyalgia patients.
触发点（TP）是肌肉中可客观证实的病灶。它们在受压时疼痛，并在牵涉区域引发疼痛。该区域可能是人类唯一的主诉部位。在犬类中，我们无法证明疼痛牵涉区域的存在。因此，只有在我们未发现骨骼、关节或神经异常，且确实发现治疗后触发点与最初的跛行一同消失时，才能诊断为触发点诱发的跛行。已经开发出几种方法来客观地证明触发点的存在。这些方法包括压力痛觉测定法、压力阈值测量、磁共振热成像和组织学。在人类中，所描述的触发点中有71%是穴位。触发点治疗包括用非侵入性或侵入性方法刺激触发点，如干针疗法或注射。在犬类中，在两类临床患者中描述了10个触发点。第一类是那些有一个或几个触发点且对治疗反应良好的犬（在约2 - 3周内成功率约为80%）。第二类是那些有许多触发点且对治疗反应不佳的犬。很可能后一组是纤维肌痛患者。
