摘要

目的:确定(1)与健康对照相比,双侧人工耳蜗植入患者的平衡是否受损;(2)声音、非言语或言语的存在是否影响站立平衡。材料与方法:对4例双侧人工耳蜗植入患者闭眼、头部静止或偏航或俯仰运动、无声音、环境背景噪音、粉红噪音、外语、英语5种声音条件下,在3种平衡条件下进行中密度柔性泡沫Romberg测试。结果:依赖测量是站立时间和运动学。在没有声音、背景噪音或粉红噪音的情况下,四分之三的受试者表现良好。在听到外语或英语单词的头部运动条件下,所有受试者的表现都很差。在偏航和俯仰条件下,受试者不能进行足够的头部运动来进行精确的运动学测量。结论:无声音环境对站立平衡技能无明显影响。添加环境噪声或粉红噪声也不会影响它们的平衡。然而,当受试者被注意力分散到单词上时,无论他们是否理解这些单词,站立平衡技能都会下降。因此,这些患者的注意力分散会导致平衡受损,这可能会损害功能性运动技能。

Balance and Sound Conditions in Adults with Bilateral Cochlear Implants
Purpose: To determine if (1) balance is impaired in patients with bilateral cochlear implants compared to healthy controls and (2) the presence of sound, non-speech, or speech affects standing balance. Materials and Methods: Four patients with bilateral cochlear implants were tested on three balance conditions on Romberg tests on medium-density compliant foam with eyes closed, with head stationary or moving in yaw or pitch, under 5 sound conditions: no sound, ambient background noise, pink noise, foreign language, English language. Results: Dependent measures were duration of standing and kinematics. Three of four subjects performed well with head still and no sound, background noise, or pink noise. All subjects performed poorly during the head movement conditions when hearing either foreign-language or English words. Subjects could not perform enough head movements during yaw and pitch conditions for accurate kinematic measurements. Conclusion: The no-sound condition did not influence standing balance skills. The addition of ambient or pink noise also did not affect their balance. However, when subjects were distracted by paying attention to words, regardless whether or not they understood the words, standing balance skills deteriorated. Thus, distracted attention in these patients leads to impaired balance, which may impair functional motor skills.
