A retrospective survey of the incidence of positive scoliosis screenings in schools for the hearing impaired was performed.
The incidence rate of scoliosis in a population with a high incidence of vestibular dysfunction was compared with the national normative incidence rate. The comparison was done to investigate the contribution of the vestibular system to scoliosis.
Several reports have emphasized a possible neural etiology to idiopathic scoliosis. Based on the experimental hypothesis that an altered vestibular processing is critical for the production of scoliosis, 100 schools for the hearing impaired were surveyed to determine their incidence of positive screenings for scoliosis. Because it is known that hearing-impaired children have a high incidence of vestibular dysfunction, it was hypothesized that their screening incidence would change if the vestibular system contributed to idiopathic scoliosis.
Surveys were sent to 100 schools for the hearing impaired asking for their most recent scoliosis screening data.
Of the 40 surveys returned, 28 schools for the hearing impaired conducted routine scoliosis screenings, of which 17 had demographics representative of the national norms. Of the 3127 students screened at these 17 schools, 1.2% of the students screened positive for scoliosis. This is significantly less than national incidence rate of 4%-10%.
The results suggested that hearing-impaired students may be a population that is protected from idiopathic scoliosis by a neural dysfunction. These data strongly suggest that idiopathic scoliosis has a neural etiology.
对听力受损学校脊柱侧弯筛查阳性的发生率进行回顾性调查。
将前庭功能障碍高发人群中的脊柱侧弯发病率与全国标准发病率进行比较。进行该比较是为了研究前庭系统对脊柱侧弯的影响。
几份报告强调特发性脊柱侧弯可能存在神经病因。基于改变的前庭处理对脊柱侧弯的发生至关重要这一实验假设,对100所听力受损学校进行了调查,以确定其脊柱侧弯筛查阳性的发生率。由于已知听力受损儿童前庭功能障碍的发生率较高,因此假设如果前庭系统导致特发性脊柱侧弯,那么他们的筛查发生率将会改变。
向100所听力受损学校发送调查问卷,索要其最新的脊柱侧弯筛查数据。
在回复的40份调查问卷中,28所听力受损学校进行了常规脊柱侧弯筛查,其中17所学校的人口统计学特征代表了全国标准。在这17所学校接受筛查的3127名学生中,1.2%的学生脊柱侧弯筛查呈阳性。这明显低于4%-10%的全国发病率。
结果表明,听力受损学生可能是因神经功能障碍而免受特发性脊柱侧弯影响的人群。这些数据有力地表明特发性脊柱侧弯存在神经病因。
