Eye-head co-ordination of patients with Parkinsonism and cerebellar ataxia was investigated and compared with that of normal subjects. In Parkinsonian patients eye-head co-ordination was of the same pattern as normals, with an accurate and stable gaze. Reaction times for both eyes and head, however, were prolonged. It was also noted that the contribution of head movements to gaze shift was abnormally large and that the gaze accuracy was decreased when the head was immobilised. In patients with cerebellar ataxia, gaze was dysmetric, often hypermetric, and was unstable during head movements. The contribution of head movements to gaze was also large. It is concluded that Parkinsonism and cerebellar diseases influence eye-head co-ordination differently.
对帕金森病患者和小脑共济失调患者的眼头协调功能进行了研究，并与正常受试者进行了比较。帕金森病患者的眼头协调模式与正常人相同，凝视准确且稳定。然而，双眼和头部的反应时间都延长了。还注意到头部运动对视线转移的贡献异常大，并且当头部固定时，凝视准确性会降低。在小脑共济失调患者中，凝视是测量不准的，通常是过强测量的，并且在头部运动期间不稳定。头部运动对凝视的贡献也很大。结论是，帕金森病和小脑疾病对眼头协调的影响不同。
