Background: Physical therapists (PTs) work in diverse communities with individuals whose identities and beliefs may differ significantly from their own. Academic institutions must include intentional curriculum aimed at graduating PTs who can skillfully navigate intercultural encounters. Being prepared to engage with difference and demonstrate skills related to intercultural competencies (ICC) will prepare entry-level PTs to provide individualized, high-quality care.

It has been shown that statistical persistence in stride intervals characteristics exist during walking, running and cycling and were speed-dependent among healthy young adults. The purpose of this study was to determine if such statistical persistence in stride time interval, stride length and stride speed also exists during self-paced continuous stairmill climbing and if the strength is dependent on stepping rate. Stride time, stride length, and stride speed were collected from nine healthy participants during 3 min of stairmill climbing at 100, 110, and 120% of their preferred stepping rate (PSR) and 5 min of treadmill walking at preferred walking speed (PWS).
