Background•Ankle sprains are most common injury
amongst college athletes•Many athletes continue to tape as
preventative measure ▫Shown to reduce ankle sprains by up to
50%
![Page 3: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/3.jpg)
How does taping help?•Mechanical support•Psychological benefits•Enhanced proprioception
▫Ability to sense a joint’s position Leads to improved balancing performance
•Direct effects on balance remain unclear

Components of Balance
Increased proprioception helps improve balance
![Page 5: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/5.jpg)
Significance •Review of literature shows little research done studying the effects of long term use of taping ▫Determine if the effects of taping on
ankle proprioception and balance continue to be significant over time
![Page 6: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/6.jpg)
Use of new information•Make more informed decisions about the best treatment plan for athletes suffering a sprained ankle ▫Better evaluate the practicality of regularly taping ankles

Question
•How does the long term use of ankle taping effect balance?
![Page 8: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/8.jpg)
Hypothesis •Ankle taping will have a larger effect on
the balance of the participants who do not regularly tape ▫Body becomes acclimatized to the tape,
such that the benefits decrease with long-term use
•Effects of taping on balancing ability will vary depending on the condition being tested
![Page 9: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/9.jpg)
Methods•16 NCAA gymnasts
are being tested ▫Balance plays a
large role in this sport
•Approximately half ‘tapers’ and the other half ‘non-tapers’ Gymnast who
regularly tapes her ankle

Single leg balance test•With hands on hips ▫Three 30 second
trials performed for each of the 4 conditions
![Page 11: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/11.jpg)
Testing conditions•Closed eyes removes visual cues
▫Increases reliance on proprioception
•2 inch thick block of foam between the foot and force platform Foam pad to make
balancing more difficult

Force Plate •Used to examine
balancing ability▫Forces used to
calculate the motion of the center of pressure (COP)
![Page 14: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/14.jpg)
Center of Pressure •Average location of the force acting
between the foot and the ground•Less movement of COP equates to
better balance
![Page 15: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/15.jpg)
Center of Mass •Less movement of COM equates to better balance
![Page 16: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/16.jpg)
Data Analysis •Compare how far and how fast COP and COM moved ▫Side to side (M/L)
▫Forward to backward (A/P)

Discussion•Contrary to hypothesis, tape negatively affects balance, regardless of group
•Long-term tapers showed balancing differences in the A/P direction and with eyes closed▫Slower corrections to balance made
![Page 24: The effect of long-term use of ankle taping on balance](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816427550346895dd5e706/html5/thumbnails/24.jpg)
Discussion•Further investigation needed
▫For preliminary data only, not all subjects have been tested yet
•Worthwhile to investigate alternatives to ankle taping
