Objective: Whilst voodoo floss bands are thought to increase range of motion through tissue compression, partial occlusion and fascial deformation, this has not been demonstrated. Consequently, this study aimed to investigate the short-term effects of using floss bands on range of motion in the ankle.
Design: This crossover design had participants go through range of motion tests prior to the application of the floss band. After the floss band was applied, participants were required to perform various non-weight bearing and body weight exercises, followed by post-intervention range of motion testing. In this study, one ankle served as the intervention (FLOSS) leg whilst the contralateral ankle served as the control (CON).
Setting: The Bangor University School of Sport, Health and Exercise Sciences (SSHES) Laboratory.
Participants: 5 recreational male athletes.
Main outcome measures: Pre and post measures included handheld goniometry for dorsiflexion (DF) and plantarflexion (PF), weight bearing lunge test (WBLT) performed with straight leg (SL) and bent leg (BL) and a subjective tightness rating (TIGHT).
Results: FLOSS resulted in one significant (p < .05) enhancement across the outcome measures as compared to CON in dorsiflexion (p < .032). However, there is a trend toward significant improvement and clinical meaningfulness (p < .15) in favor of FLOSS over CON in bent leg weight bearing lunge test (p < .145).
Conclusion: Applying floss bands to extremities to achieve an increase in range of motion is a plausible and potentially helpful treatment alternative. This study was limited by a small sample
