[Purpose] In this study, we investigated the effectiveness of elastic tape in increasing
the dorsiflexion angle and plantar flexor strength in healthy individuals. [Participants
and Methods] This randomized controlled trial included 24 healthy university students who
were categorized into the following groups (12 participants in each group): the
intervention group (elastic tape was applied to the dominant foot) and the control group
(no intervention was performed). We performed intergroup comparison of the pre- and
post-intervention dorsiflexion angles and plantar flexor strength. Additionally, we
performed subgroup analyses based on a straight-leg raise angle of 70°. [Results] We
observed no significant intergroup differences in the dorsiflexion angle or plantar flexor
strength. However, the post-intervention dorsiflexion angle was significantly greater than
the pre-intervention angle in the subgroup with a straight-leg raise angle of <70°
among participants in the elastic tape group. [Conclusion] Elastic tape application may
effectively increase the dorsiflexion angle in individuals without hamstring
extensibility.
