The dataset provides postural sway data from 23 subjects as well as their summary. The file named “Scatter_plots.xlsx” includes postural sway directions for the 23 subjects on all experimental conditions (gaze change and auditory stimulation). HLEL denotes an experiment in which a subject turned his/her head left and his/her gaze left. For the details of such notation, please read the next paragraph. The postural sway direction of each trial was given in the second to 13th lines for the 23 subjects (Sub_1 to Sub_23). The averaged directions were given in the 17th to 22th lines. The 26th to 44th lines represent the averaged postural directions between head/gaze conditions and sound conditions. The four block correspond to the four graphs, A to D, on the right.

A file named as Sub_X.xlsx includes all trajectories of a subject. Here, X represents the subject ID, which is between 1 and 23. Each sheet in a file contains a trajectory in an experimental condition. As mentioned earlier, a notation such as “HRER” denotes an experiment in which a subject turned his/her head and gaze right. There are two sheets begins with HRER because two trials were carried out in each experimental condition. HLER represents head left, gaze right. The other combinations of HxEy were named in the same manner. CSL/CSR denotes the sound simulation was applied from the left/right, the first C means eyes closed.

Each sheet includes four data columns. Columns A and B are the raw positions on the x and y axes for the entire 40 s trial. Columns D and E represent the normalized positons, which were translated so that the position at the onset of the neck dorsal muscle stimulation became the origin. G2 cell denotes the postural sway direction.

For the details of the experimental conditions, please consult the original article.

本稿では23名の被験者の測定結果と解析結果を提供する(実験条件などの詳細は原論文を参照のこと).“Scatter_plots.xlsx”というファイルには,23名の被験者の全実験条件での身体傾斜方向が含まれている。HLELは頭部が左方向,視線が左方向を向いた試行である(表記の詳細については,次の段落を参照)。各試行での23名の被験者(Sub_1からSub_23)の身体傾斜方向が2行目から13行目に示されている。各条件の平均値が17行目から22行目に示されている。26行目から44行目は,視線条件と聴覚刺激条件ごとの身体傾斜方向の平均値が示されている。4つのブロックは,右の4つのグラフ(A~D)に対応している。 Sub_X.xlsx というファイルは,1人の被験者の全ての条件の軌跡を含んでいる。ここでXは被験者の番号で,1~23のいずれかである。ファイル中の各シートは,1つの実験条件の1試行の軌跡のデータを含む。前述のように,HRERなどの表記は被験者が頭部・視線ともに右に動かしたことを示している。各条件について2回の試行を行ったので,1条件につき2つのシートがある。HLERは頭部・左,視線・右を表す。HxEyなどの表記も同様に命名されている。CSL/CSRは聴覚刺激の左(CSL),右(CSR)を表す。最初のCは閉眼であることを示す。 各シートは4列のデータを含む。A列とB列はx軸y軸生の値である。D列とE列は,振動刺激開始時点の位置が原点となるように平行移動した座標である。G2セルは身体傾斜方向を表している。
