• Development of Line Bisection Task Software Using a Tablet PC

  Sanada Hirofumi, Takezawa Megumi, Ota Hisaaki, Saito Hidekazu

  IEEJ Transactions on Electronics, Information and Systems ( The Institute of Electrical Engineers of Japan )  145 ( 1 ) 122 - 123  2025.01

  　View Summary

  This study presents the development of a tablet PC-based Line Bisection Task (LBT) software. The software was created through an iterative process involving collaboration between software developers and occupational therapy researchers, incorporating user feedback to refine the prototype. The resulting software addresses the limitations of traditional paper-and-pencil LBT methods, underscoring the value of interdisciplinary collaboration in healthcare technology development. The software offers several advantages over paper-and-pencil LBT, including enhanced flexibility, improved efficiency, real-time feedback, and reduced risk of human error. This tablet-based LBT software is expected to provide an efficient and effective tool for assessing spatial perception.

  ＜文献概要＞上肢機能評価バッテリーの使用状況について,アンケート調査で得られた結果から,上肢機能評価の現状と問題点を明らかにし,その対応を検討した.北海道内の病院等に所属する作業療法部門代表者に郵送式のアンケート調査を実施し,対象疾患に脳卒中または脳損傷を含む75施設を分析対象とした.その結果,上肢機能評価バッテリーの使用・不使用理由として,評価バッテリー・物品の保有,未保有・不足の影響が大きいことが明らかとなり,評価に対する知識・技術不足も不使用の理由として挙げられた.また臨床現場では,ADL上の実動作に関する上肢機能評価の必要性を感じていることが明らかとなった.以上より,上肢機能評価についての知識・技術の指導や,新たな評価バッテリー開発によって,作業療法技術向上や円滑な治療介入につながる可能性が示唆された.

• Does 20 Hz Transcranial Alternating Current Stimulation over the Human Primary Motor Cortex Modulate Beta Rebound Following Voluntary Movement?

  　View Summary

  Beta frequency oscillations originating from the primary motor cortex increase in amplitude following the initiation of voluntary movement, a process termed beta rebound. The strength of beta rebound has been reported to predict the recovery of motor function following stroke, suggesting therapeutic applications of beta rebound modulation. The present study examined the effect of 20 Hz transcranial alternating current stimulation (tACS) on the beta rebound induced by self-paced voluntary movement. Electroencephalograms (EEGs) and electromyograms (EMGs) were recorded from 16 healthy adults during voluntary movements performed before and after active or sham tACS. There was no significant change in average beta rebound after active tACS. However, the beta rebound amplitude was significantly enhanced in a subset of participants, and the magnitude of the increase across all participants was negatively correlated with the difference between individual peak beta frequency and tACS frequency. Thus, matching the stimulus frequency of tACS with individual beta frequency may facilitate therapeutic enhancement for motor rehabilitation.

• Validity and Reliability Study of a Line Bisection Task on Tablet Personal Computer

  Asian Journal of Occupational Therapy ( Japanese Association of Occupational Therapists )  20 ( 1 ) 142 - 148  2024

  　View Summary

  Objective: Recently, we developed a line bisection task (LBT) that could be performed on a tablet personal computer (PC) by recording the results and automatically calculating the lateral deviation from the true center for each trial. The present study aimed to verify the validity and reliability of the LBT on a tablet PC. Additionally, we examined whether there were any differences between the results of the tablet and paper LBTs. Methods: The LBT was performed both on paper and tablet PC by 26 right-handed healthy adult volunteers (mean age 21.2 ± 2.1 years). Lines of three different lengths (200, 100, and 50 mm) were presented five-times in a pseudorandom order in each task condition. The participants were asked to mark a subjective midpoint with a pencil or a dedicated pen. Additionally, eight participants performed the LBT on the tablet twice to evaluate reliability. Results: Data analysis revealed a significant and “strong” to “very strong” correlation between the results of paper and tablet LBTs for each line length. Additionally, “good” test-retest reliability was confirmed by the results of the tablet LBT. There was no difference in the LBT results for each line length between the two task conditions. Conclusions: The validity and reliability of the newly developed tablet LBT were confirmed. Additionally, the LBT performed on the tablet PC yielded results equivalent to those obtained when performed on paper.

• Event-Related Brain Potentials N140 and P300 during Somatosensory Go/NoGo Tasks Are Modulated by Movement Preparation.

  Brain sciences   14 ( 1 )  2023.12  [International journal]

  　View Summary

  The Go/NoGo task requires attention and sensory processing to distinguish a motor action cue or 'Go stimulus' from a 'NoGo stimulus' requiring no action, as well as motor preparation for a rapid Go stimulus response. The neural activity mediating these response phases can be examined non-invasively by measuring specific event-related brain potentials (ERPs) using electroencephalography. However, it is critical to determine how different task conditions, such as the relationship between attention site and movement site, influence ERPs and task performance. In this study, we compared attention-associated ERP components N140 and P300, the performance metrics reaction time (RT) and accuracy (%Error) and movement-related cortical potentials (MRCPs) between Go/NoGo task trials in which attention target and movement site were the same (right index finger movement in response to right index finger stimulation) or different (right index finger movement in response to fifth finger stimulation). In other Count trials, participants kept a running count of target stimuli presented but did not initiate a motor response. The N140 amplitudes at electrode site Cz were significantly larger in Movement trials than in Count trials regardless of the stimulation site-movement site condition. In contrast, the P300 amplitude at Cz was significantly smaller in Movement trials than in Count trials. The temporal windows of N140 and P300 overlapped with the MRCP. This superposition may influence N140 and P300 through summation, possibly independent of changes in attentional allocation.
