Background: Transcutaneous electrical sensory nerve stimulation (TESS) is used to enhance the recovery of sensorimotor function in post-stroke hemiparesis. However, TESS efficacy for post-stroke gait disturbance remains unknown. We hypothesized that TESS on the area innervated by the tibial nerve, targeting the superficial plantar sensation, combined with gait training would improve gait function in patients with gait disturbance caused by severe superficial sensory disturbance after stroke.Case: A 42-year-old man was referred to the convalescent rehabilitation hospital 4 months after a left pontine hemorrhage. He showed severe superficial sensory disturbance without motor paresis in the right lower leg and planta pedis. Gait training with TESS on the tibial nerve innervated area was performed, targeting plantar sensation according to an N-of-1 study design of a single-case ABCAB that included two 10-min sessions of gait training without TESS (phase A), two gait training sessions with TESS targeting the right plantar sensation (phase B), and one session with TESS targeting the upper leg sensation as control (phase C). The patient showed increased gait distance and stride length, improved superficial sensation on the right planta pedis, and improved balance after phase B, but not after phases A and C.Discussion: Gait training with TESS on the tibial nerve innervated area improved gait ability, superficial plantar sensation on the targeted side, and balance function in a post-stroke patient with sensory disturbance. Gait training with TESS may be effective for gait dysfunction caused by sensory disturbance in patients with central nervous system disorders.

Objectives: This study aimed to update the current knowledge on non-invasive brain stimulation (NIBS) effects, such as repetitive transcranial brain stimulation and transcranial direct current stimulation, in patients with post-stroke dysphagia (PSD).Methods: We summarized the basic principles and therapeutic strategies of NIBS. We then reviewed nine meta-analyses from 2022 that investigated the efficacy of NIBS in PSD rehabilitation.Results: Although dysphagia is a common and devastating sequela of stroke, the efficacy of conventional swallowing therapies remains controversial. NIBS techniques have been proposed as promising approaches for managing PSD via neuromodulation. Recent meta-analyses have shown that NIBS techniques are beneficial for the recovery of patients with PSD.Conclusions: NIBS has the potential to become a novel alternative treatment for PSD rehabilitation.

事物の意味を認知することは人間の持つ高次認知機能のうちでも特に中心的な機能の一つである。本研究では経頭蓋直流電流刺激(tDCS)を用いて、近年意味認知の中枢と考えられている大脳皮質左前側頭葉(ATL)の活動を促進したときに日本語単語意味認知能力の向上が見られるかどうかを検討した。結果としてtDCSによる類義語の判断成績向上が認められ、この効果は事前調査で難易度が高いとされた試行群において得に顕著であった。本知見はATL領域と意味認知との関係についてその因果的関係をさらに強力に立証すると同時に、意味認知障害の臨床においてtDCSが意味認知能力の維持・向上の補助手段として用いられる可能性について示唆するものである。
