The time-course effects of talus taping on ankle dorsiflexion range of motion

Background/Aims Talus taping may be an effective physiotherapeutic treatment for equinus (passive dorsiflexion range of motion <10 degrees). However, the time-course effects of this intervention are unknown. The aims of this study were to identify the effect that the application of talus tape for 48 hours during normal functional activities has on dorsiflexion range of motion, and to determine whether any changes in dorsiflexion range of motion persisted until 5 days after removal (study day 7). Methods A total of 16 healthy participants (mean age 28.3 +/- 8 years) were recruited. Participants' were randomly assigned to control and intervention conditions. Baseline measures of dorsiflexion range of motion were taken in both ankles using the weight-bearing lunge test. The intervention ankle had talus tape applied, which remained in place for 48 hours during normal functional activities. To determine the time-course effects, dorsiflexion range of motion was reassessed in the control and intervention ankles immediately following removal of the tape (at 48 hours) and again 5 days later, on day 7. Findings Dorsiflexion range of motion in the taped intervention ankle increased significantly between the baseline and 48-hour measures. However, when reassessed at day 7, participants' dorsiflexion range of motion had returned to baseline levels. There were no significant differences in the control ankle across all three measures. Conclusions Applying talus tape for 48 hours during normal functional activities results in immediate but not long-lasting changes in dorsiflexion range of motion.
