2 Introduction Restricted range of motion is an issue that athletes and recreationally active individuals may experience Range of motion may be restricted due to inflammation or joint swelling surgical hardware muscle tightness immobilization > 1 week 1

3 Ankle Dorsiflexion Commonly limited in healthy individuals and in patients recovering from lateral ankle sprain 2 Affects daily activities such as walking, running, stair climbing and squatting 2, 3 Research has found that decreased dorsiflexion range of motion contributed to higher risk of lateral ankle sprains and other lower limb injuries 4, 5

4 Voodoo Floss 7 foot long by 2 inch wide latex band Used by wrapping around joints and muscle bellies Looking to improve 6 range of motion restore joint mechanics unglue matted down or previously injured tissue

5 Purpose The purpose of this study was to explore the acute effects of the Voodoo Floss band on gastrocnemius length when compared to the control group.

6 Methods: Design Randomized Control Study Independent Variables Group Voodoo floss group Standard of care group Time Pre and post measurements Dependent Variable Gastrocnemius Length

7 Methods: Subjects Inclusion Criteria Males and females years old < 10 of DF ROM in open chain measure of the dominant leg Exclusion Criteria Excessive gastrocnemius length of > 20 Loss of TCJ motion of < 20 Lower extremity injury within the past 6 months Open reduction internal fixation (ORIF) Allergy to latex material Open wounds/cuts Poor circulation (varicose veins, diabetes, DVT, PAD)

8 Methods: Instruments

9 Methods: Procedure Subject Screening (informed consent form, general medical history questionnaire, inclusion/exclusion screen) Baseline Measurements Randomly Allocated Voodoo Floss Intervention Control Group Post Intervention Measurements Post Intervention Question

10 Screening Open Chain Gastrocnemius Length Open Chain Talocrural Joint Range of Motion

11 Closed Chain Measurement

12

13 Voodoo Floss Intervention

14 Closed Chain Measurement

15 Methods: Statistical Analysis Means and standard deviation were calculated A two-way mixed ANOVA was used to assess for CCDF differences between groups over time Post hoc pairwise comparisons α level was a priori at p 0.05

16 Descriptive Statistics Baseline Characteristics of Subjects Subjects (N) 59 Male (n) 8 Female (n) 51 Age (y) 21.6 ± 3.5 Height (cm) ± 8.1 Mass (kg) 68.5 ± 12.5

17 Results: Dorsiflexion ROM Control Voodoo Average Pre Intervention Average Post Intervention

18 Results: Post Intervention Question #1 100% 90% 80% 70% 60% Do you feel the same, tighter, or looser than before the intervention? 50% 40% 30% Control Voodoo 20% 10% 0% Same Tighter Looser Subject Answer

19 Results: Post Intervention Question # % 80.00% 70.00% 60.00% Do you feel as thought you gained motion? 50.00% 40.00% Control Voodoo 30.00% 20.00% 10.00% 0.00% Yes No

20 Discussion Our results were not statistically significant despite seeing minor differences between the control and intervention group. Voodoo floss did not have a greater effect on closed chain dorsiflexion when compared to static stretching alone.

21 Discussion A change was seen in closed chain dorsiflexion over time Average increase was 2 after 2 minute bout of stretching Other studies looking at the effect of static stretching on ankle DF found small gains ranging from Konor et al. found MDC for CCDF was

22 Discussion When asked the post intervention questions A larger percentage of subjects in the Voodoo Floss group reported feeling looser afterwards However, similar amount of subjects in both groups reported feeling as though they gained motion Only a small number of subjects in both groups stated they felt the same or tighter after the intervention and felt they did not gain motion

23 Limitations Subjects pre-participation activities Subject population was not very broad Some subjects felt a strong stretch while others did not Static stretching alone may not have been effective Novice s to using Voodoo Floss

24 Clinical Implications Voodoo Floss alone did not show much increase in CCDF, but it was found to be a safe technique/tool to use that subjects preferred subjectively

25 Future Research Use the band with active stretches and exercises Try using the band with multiple bouts Investigate the lasting effects of each intervention
