随病情的进展,均出现四肢痉挛性瘫痪,肌力Ⅲ~Ⅳ级,肌张力呈折刀样增高,四肢腱反射亢进,两侧踝阵挛及Babinski征(+)。
As the disease progressed slowly , the patients presented with spastic paralysis of four extremities , reduced muscle strength ( 3 to 4 degree ), clasp-knife like of muscular tension , hyperactivity of tendon reflexes , ankle clonus and presence of Babinski sign .
-
踝阵挛阳性是另一有重要意义的体征。
The positive sign of ankle clonus is an another important sign .
-
下肢肌张力增高,肌力Ⅳ级,腱反射亢进,髌、踝阵挛阳性,Babinski征阳性,屈性病理反射阳性;
Hypermyotonia and ⅳ - level myodynamia in both lower extremities , tendon hyperreflexia , knee cap clonus ( + ), ankle clonuses ( + ), Babinski sign ( + ), and flexion pathologic reflexes ( + );

踝阵挛试验在脊柱侧凸手术中的监测价值
The ankle clonus test in surgery of scoliosis
-
踝阵挛出现的时间明显早于唤醒试验(P<0.001)。
The ankle clonus test appeared significantly earlier than the wake-up test ( P < 0.001 ) .
-
由同一位医生在1周内2次评定患侧下肢的痉挛,内容包括跟腱反射、小腿三头肌的肌张力及踝阵挛。
Spasticity was assessed twice at the same time on different days within one week by the same doctor .
-
踝阵挛及病理反射消失率100%,12例术前膝腱反射亢进的患者,术后膝反射减弱。
All ankle clonus and pathologic reflexes disappeared . The brisk knee reflex in 12 patients became sluggish after operation .
-
因此在本观察中,踝阵挛试验无真阳性和假阴性结果,4例假阳性结果(8.16%)。
Therefore , the ankle clonus test had no false-negative or true-positive result and 4 false-positive results ( 8.16 % ) .
-
结果19例患者术后肢体痉挛都得到缓解(100%),表现在肌张力下降,踝阵挛和病理反射消失或减轻。
RESULTS Spasticity in lower extremities got lessened in all patients ( 100 % ), which showed decreasing of muscle tone , disappearance or decrease of ankle tremor and Babinski sign .
-
结果术后随访3~6个月,16例患者肌张力增高均得到缓解,踝阵挛和病理反射消失或减轻。
Results During the follow up of 3 to 6 months , all the sixteen patients showed decreasing of the muscular spasticity , disappearance or relief of the ankle tremor and Babinski sign .
-
结论:踝阵挛试验对脊柱侧凸矫形术中脊髓功能的监测具有应用价值,且出现较早、简单易行,应作为常规监测,甚至可取代唤醒试验。
Conclusion : The ankle clonus test is a safe , easily performed and early parameter for intraoperative monitoring the spinal cord function during corrective surgery of scoliosis and should be routinely scrutinized .
