Abstract
Damage to the cerebellum results in dysfunctional standing postural control. Patients with cerebellar ataxia have a larger sway in the center of gravity (COG) while standing. Transcranial direct current stimulation (tDCS) has been applied in the rehabilitation of patients with central nervous system disorders; however, its effect on COG sway in patients with cerebellar ataxia remains unknown. We aimed to confirm the effects of anodal cerebellar tDCS (ctDCS) combined with physical therapy on COG sway in a patient with cerebellar ataxia using a retrospective ABA single-case study design. This study involved a patient with left cerebellar hemorrhage. Walking and postural balance rehabilitation were conducted in phase A. Anodal ctDCS was combined with the walking and postural balance rehabilitation in phase B. We measured COG sway in the open- and closed-eyes standing conditions daily throughout all the phases. In the open-eyes standing condition, there was no significant change in COG sway in phase B. Conversely, in the closed-eyes standing condition, the circumferential area, total sway path length, and anteroposterior sway path length decreased in phase B. No change was observed in the mediolateral sway path length. The combination of anodal ctDCS and physical therapy may decrease COG sway in patients with cerebellar ataxia in the closed-eyes standing condition, and its effect may be greater in the anteroposterior direction.
小脑受损会导致站立姿势控制功能障碍。小脑共济失调患者站立时重心(COG)摇摆较大。经颅直流电刺激(tDCS)已被用于中枢神经系统疾病患者的康复治疗,但它对小脑共济失调患者重心摇摆的影响仍不清楚。我们的目的是采用回顾性 ABA 单病例研究设计,证实阳极小脑 tDCS(ctDCS)结合物理疗法对小脑共济失调患者 COG 摇摆的影响。本研究涉及一名左侧小脑出血患者。我们在所有阶段每天测量睁眼和闭眼站立状态下的COG摇摆。相反,在闭眼站立条件下,周长、总摇摆路径长度和前胸摇摆路径长度在 B 阶段均有所下降,而内外侧摇摆路径长度则没有变化。小脑共济失调患者在闭眼站立状态下,将阳极ctDCS和物理疗法结合使用可能会减少COG摇摆,而且其在前胸方向的效果可能更大。
