Sports Medicine Research Practices for Categorizing Transgender and/or Intersex Participants.

Context: Approximately 1 to 1.4 million individuals (0.58% of the population) in the United States identify as transgender, yet no literature could be found regarding how researchers should adapt clinical research studies when intersex or transgender individuals volunteer as participants.

Acute and Residual Effects of IASTM and Roller Massage Stick on Hamstring Range of Motion.

Purpose: Fascial adhesions can reduce range of motion (ROM). Different techniques of varying costs have been studied to release these adhesions and restore normal ROM, but none have compared instrument-assisted soft tissue mobilization (IASTM) with a roller massage stick. The objective was to compare the acute and residual effects of IASTM and a roller massage stick on active and passive hamstring ROM after a single treatment.
