Vibratory studies were performed on 10 adolescent subjects being followed for congenital scoliosis. The average age was 12 years 4 months and the average curve was 32 degrees. Twenty-one age-matched controls underwent identical studies. Threshold to detection of vibratory stimuli in the upper and lower extremities was quantified. Results showed that the scoliotic subjects were consistently less sensitive than the controls in the lower but not the upper extremity. The occurrence of hyposensitivity in only the lower extremity of persons with congenital scoliosis implies that the sensory deficit is secondary to the spinal deformity itself rather than a primary etiologic factor.
对10名因先天性脊柱侧弯而接受随访的青少年受试者进行了振动觉研究。平均年龄为12岁4个月，平均侧弯角度为32度。21名年龄匹配的对照组受试者接受了相同的研究。对上下肢振动刺激的检测阈值进行了量化。结果显示，脊柱侧弯受试者在下肢的敏感性始终低于对照组，而上肢则不然。先天性脊柱侧弯患者仅下肢出现感觉减退，这意味着感觉缺陷是脊柱畸形本身所致，而非原发性病因。
