... position. To measure the stride length, a video analysis software Dartfish Team Pro 5.5 (Dartfish, Fribourg, Switzerland) was used. Assuming the distance between the tapes placed at 1-m intervals was 1.00 cm, the distance between the left and right heel positions at the heel contact of one side was converted from centimeters to meters (Fig. 1). Next, the Multi-PAS II system (DKH, Tokyo, Japan) was used for P-RT measurement. PH-1211 (DKH, Tokyo, Japan) was used as an audio trigger device to cue the phonation task. PH-1131A1 (DKH, Tokyo, Japan) and Diversity Wireless Receiver WX-4200 (Panasonic, Osaka, Japan) were used for audio data conversion. A measurement headset ...
