Taping is generally being used to take some of the load off an injured structure for pain relief. The choice of tape and the technique we use will vary from one situation to another but tends to drop into one of two categories:
We may be looking to brace a segment of the foot to limit painful movement as much as possible. A good example would be taping up the big toe joint, perhaps in an older patient with an acute arthritic pain or in a rugby player with a turf toe injury. In these cases we are using a rigid tape like zinc oxide.
The other big use for taping is to “share the load” of a tissue that we still want to allow to move and function as well as possible. An example of this might be when taping up someone’s painful tibialis posterior tendon (like the blue tape in the picture) so it can still move but hopefully giving the patient less pain and more confidence which can be so important to get you on-side with the “homework” (exercises) we are likely to ask you to do!
The trick with any taping technique is sound anatomy knowledge and knowing in detail how the mechanics of the foot and ankle work. Done right, people are often shocked at how well this can work!
