Examination of the superficial abdominal reflexes in patients thought to have idiopathic scoliosis has been considered possibly beneficial for deciding who should have magnetic resonance imaging to rule out syringomyelia. The purpose of this study was to determine what is normal for this examination. Thirty normal adolescents and 35 normal young adults underwent testing of the superficial abdominal reflexes and the patellar and Achilles deep tendon reflexes. Each test was repeated two times. Thirty-nine (60%) subjects had bilaterally equal abdominal reflexes. Nine (14%) subjects had asymmetric reflexes, and seven (11%) subjects had no reflex in at least one quadrant. No subjects had reflexes present on one side and absent on the other. Ten (15%) subjects had absence of the abdominal reflexes in all quadrants. Sixteen (25%) subjects had extinguishing of the reflex in at least one quadrant as the test was repeated. Eleven of these had asymmetric or partially absent reflexes initially. In contrast, the patellar and Achilles reflexes were more consistent. The patellar reflexes were bilaterally equal in 52 (85%), asymmetric in eight (13%), and absent in one (2%). The Achilles reflexes were bilaterally equal in 59 (97%), asymmetric in one (2%), and absent in one (2%). The finding of abdominal reflexes consistently present on one side and consistently absent on the other side did not occur in our normal subjects. This finding might warrant further workup if found in a patient with scoliosis. Other variations in abdominal reflex testing such as asymmetries, absent in some quadrants, and absent in all quadrants are fairly common in normal subjects.
对于疑似患有特发性脊柱侧凸的患者，检查其腹部浅反射可能有助于决定哪些患者应接受磁共振成像检查以排除脊髓空洞症。本研究的目的是确定该检查的正常表现。30名正常青少年和35名正常青年接受了腹部浅反射以及髌腱和跟腱深反射的测试。每项测试重复两次。39名（60%）受试者双侧腹部反射相等。9名（14%）受试者反射不对称，7名（11%）受试者至少在一个象限无反射。没有受试者一侧有反射而另一侧无反射。10名（15%）受试者所有象限均无腹部反射。16名（25%）受试者在重复测试时至少在一个象限出现反射消失。其中11名最初反射不对称或部分缺失。相比之下，髌腱反射和跟腱反射更具一致性。髌腱反射双侧相等的有52名（85%），不对称的有8名（13%），消失的有1名（2%）。跟腱反射双侧相等的有59名（97%），不对称的有1名（2%），消失的有1名（2%）。在我们的正常受试者中未出现一侧腹部反射持续存在而另一侧持续缺失的情况。如果在脊柱侧凸患者中发现这一情况，可能需要进一步检查。腹部反射测试中的其他变化，如不对称、某些象限缺失以及所有象限缺失，在正常受试者中相当常见。
