Abstract

Background

Idiopathic normal pressure hydrocephalus (iNPH) is characterized by cerebrospinal fluid circulation disorders, and presents as gait and balance disturbances similar to those observed in other incurable neurological diseases. Although previous studies have reported deficits in bimanual coordination among patients with iNPH, these potential pathological characteristics have not received much attention to date. This study investigated the temporal characteristics of a bimanual finger-tapping task in patients with iNPH, focusing on within- and between-hand coordination.

Methods

Study participants comprised three groups: patients with iNPH (N = 19, mean age = 76.9 ± 5.6 years), older adults (N = 19, 76.4 ± 5.3 years), and younger adults (N = 13, 32.2 ± 8.5 years). Participants performed a bimanual finger-tapping task under five conditions that manipulated the temporal differences between the two taps.

Results

The iNPH group exhibited significantly greater errors in both within- and between-hand coordination tasks compared to the other two groups.

Conclusion

These results suggest that assessing temporal errors in bimanual coordination tasks, particularly within-hand coordination, may be useful for uncovering pathological characteristics specific to iNPH.

特发性正常压力脑积水患者双臂协调的显著特征

背景特发性正常压力脑积水（iNPH）的特点是脑脊液循环障碍，表现为步态和平衡障碍，与其他无法治愈的神经系统疾病相似。虽然以前的研究曾报道过 iNPH 患者的双足协调能力存在缺陷，但这些潜在的病理特征迄今为止尚未得到广泛关注。本研究调查了 iNPH 患者双指敲击任务的时间特征，重点关注手内和手间的协调。研究参与者包括三组：iNPH 患者（19 人，平均年龄为 76.9 ± 5.6 岁）、老年人（19 人，76.4 ± 5.3 岁）和年轻人（13 人，32.2 ± 8.5 岁）。结果与其他两组相比，iNPH 组在手掌内和手掌间协调任务中表现出明显更大的误差。结论这些结果表明，评估双手协调任务中的时间误差，尤其是手掌内协调，可能有助于发现 iNPH 的病理特征。

期刊介绍： The journal "Acta Neurochirurgica" publishes only original papers useful both to research and clinical work. Papers should deal with clinical neurosurgery - diagnosis and diagnostic techniques, operative surgery and results, postoperative treatment - or with research work in neuroscience if the underlying questions or the results are of neurosurgical interest. Reports on congresses are given in brief accounts. As official organ of the European Association of Neurosurgical Societies the journal publishes all announcements of the E.A.N.S. and reports on the activities of its member societies. Only contributions written in English will be accepted.
