Studies have shown that perceptual and cognitive asymmetries are present in the auditory system in patients with adolescent idiopathic scoliosis (AIS). The Dichotic Listening (DL) paradigm was formerly performed in non-forced (NF) conditions only, and no study has examined the conditions of attention to one ear.
To investigate the perceptual and cognitive asymmetry in the auditory system in patients with AIS as well as the asymmetry changes according to the curvature characteristics of patients with AIS.
The DL paradigm was performed on 38 patients with AIS and 10 healthy individuals in all conditions (NF, Forced Right [FR], Forced Left [FL]).
In the NF and FL conditions, the mean number of correct responses for the left ear was significantly lower in patients with AIS than in healthy individuals ( < 0.05). The correct responses for the right ear in the NF condition, right and left ear in the FR condition, and right ear in the FL condition did not show a significant difference between the groups ( > 0.05). Also, there was no difference between patients with AIS with both functional 3-curve and 4-curve ( > 0.05).
Our study indicates perceptual and cognitive asymmetry or lateralisation in the auditory system in patients with AIS. The asymmetry might be caused by the inability to direct their attention to the left ear, which is not affected by their curvature type. Further studies are needed to investigate perceptual and cognitive asymmetry behaviour models in the auditory system in patients with AIS.
Determination of perceptual and cognitive asymmetry in the auditory system may offer a new perspective on conservative treatment protocols for AIS patients. Besides, the DL paradigm can be easily used in patients with AIS as a non-invasive evaluation method in clinics.
研究表明，青少年特发性脊柱侧凸（AIS）患者的听觉系统存在感知和认知不对称。双耳分听（DL）范式以前仅在非强迫（NF）条件下进行，尚无研究考察单耳注意力条件。
研究AIS患者听觉系统的感知和认知不对称以及根据AIS患者的脊柱弯曲特征的不对称变化。
对38例AIS患者和10名健康个体在所有条件下（NF、强迫右耳[FR]、强迫左耳[FL]）进行DL范式测试。
在NF和FL条件下，AIS患者左耳的平均正确反应次数显著低于健康个体（<0.05）。NF条件下右耳、FR条件下右耳和左耳以及FL条件下右耳的正确反应在两组之间没有显著差异（>0.05）。此外，具有功能性三弯和四弯的AIS患者之间也没有差异（>0.05）。
我们的研究表明AIS患者听觉系统存在感知和认知不对称或偏侧化。这种不对称可能是由于无法将注意力指向左耳所致，且不受其脊柱弯曲类型的影响。需要进一步研究来探究AIS患者听觉系统的感知和认知不对称行为模型。
确定听觉系统中的感知和认知不对称可能为AIS患者的保守治疗方案提供新的视角。此外，DL范式作为一种非侵入性评估方法，可在临床上轻松应用于AIS患者。
