Clinical examination of the tendon reflexes is helpful in localising lesions in the nervous system, which is an important step in the diagnosis of neurological disorders. The large intra- and interindividual variations of reflex amplitudes make interpretation difficult. Published interobserver agreement studies provide conflicting results. The diagnostic specificity of unequivocally abnormal reflexes is moderate to good (70-95%, decreasing with increasing age), but the sensitivity is lower (50-70%), both for peripheral and for central lesions. This implies that the finding of a clearly abnormal reflex pattern is often helpful, but the finding of normal reflexes usually does not exclude a neurological lesion.
腱反射的临床检查有助于神经系统病变的定位，这是诊断神经疾病的重要步骤。反射幅度在个体内和个体间存在较大差异，这使得解释变得困难。已发表的观察者间一致性研究结果相互矛盾。明确异常反射的诊断特异性为中度至良好（70-95%，随年龄增长而降低），但敏感性较低（50-70%），无论是外周病变还是中枢病变。这意味着发现明显异常的反射模式通常是有帮助的，但发现正常反射通常并不能排除神经病变。
