In the present study, we evaluated the effects of the Limb Activation Treatment (LAT) alone and in combination with the Contralateral Arm Vibration (CAV) on left neglect (LN) rehabilitation. We conceived them as techniques that both prompt the activation of the lesioned right hemisphere because of the activation (with the LAT as an active technique) and the stimulation (with the CAV as a passive technique) of the left hemibody. To test the effect of the simultaneous use of these two techniques (i.e., LAT and CAV) on visuo-spatial aspects of LN, we described the case of an LN patient (GR), who showed high intra-individual variability (IIV) in performance. Given the high IIV of GR, we used an ABAB repeated-measures design to better define the effectiveness of the combined application of LAT and CAV, as a function of time. The results showed an improvement of GR's performance on the Bells test following the combined application of LAT and CAV, with respect to the application of LAT alone. We did not find, however, significant effects of treatment on two other LN tests (i.e., Line bisection and Picture scanning). We propose that the combined application of LAT and CAV can be beneficial for some aspects of LN.
在本研究中，我们评估了单独使用肢体激活治疗（LAT）以及与对侧手臂振动（CAV）联合使用对左侧忽略（LN）康复的影响。我们认为它们是两种技术，都可以通过激活（LAT 是一种主动技术）和刺激（CAV 是一种被动技术）左侧身体来促使受损的右半球激活。为了测试同时使用这两种技术（即 LAT 和 CAV）对 LN 视空间方面的影响，我们描述了一位 LN 患者（GR）的病例，他的表现具有很高的个体内变异性（IIV）。鉴于 GR 的高 IIV，我们使用 ABAB 重复测量设计来更好地定义 LAT 和 CAV 联合应用的有效性，作为时间的函数。结果表明，与单独使用 LAT 相比，GR 在 Bells 测试中的表现随着 LAT 和 CAV 的联合应用而有所改善。然而，我们没有发现治疗对另外两项 LN 测试（即线二分和图片扫描）有显著影响。我们提出，LAT 和 CAV 的联合应用可能对 LN 的某些方面有益。
