The Measurable Support of the Ankle Joint by Conventional Methods of Taping

Abstract
In this study, the support provided by four methods of ankle taping was objectively measured before and after exercise. Measurements were obtained by a cable tensiometer as the foot was passively moved in plantar flexion and inversion through the normal range of movement. The results clearly showed wide variability among the subjects in the measured support of each type of strapping both before and after exercise. However, the data indicated that the greatest support was provided by the basket weave with the combination stirrup and heel lock. The supporting strength of the basket weave with stirrup was almost as great. The least support was given by the standard basket weave both before and after exercise. The results clearly demonstrated that as much as 40 per cent of the net supporting strength of the strappings was lost after ten minutes of vigorous exercise. Inspection of the strappings following testing disclosed that almost invariably the supporting strips of tape were either broken or the anchoring lateral strips were displaced downward. While some support is given to the ankle joint by current methods of taping, it is doubtful that the protection is as great as many believe. Most certainly the stress of exercise quickly loosens the adhesive supports, leaving the ankle joint with only limited protection.
