DOT significantly increases harmstring flexibility (passive straight leg raise) in healthy participants (sportsmen). A significant moderate positive correlation was identified between the GRoC and the mean change score of hamstring flexibility in all participants. Participants believed that the intervention improved their hamstring flexibility and considered the treatment to be relaxing (Winkelmann et al. 2018).
The study was conducted with the deep oscillation therapy device HIVAMAT® 200, predecessor of the personal and evidence devices.
