Injury prevention in athletics has been the focus of much attention in recent years. Due to the frequency of injuries arising about the ankle joint, primarily involving the lateral collateral ligament complex, many attempts have been made to reinforce the ankle joint through the use of adhesive tape and preventative strapping. The purpose of preventative ankle strapping, as used in athletics, is to reduce the frequency and severity of ankle injuries. Numerous methods of preventative strapping have been employed in athletic circles which attempt to restrict or limit the specific motion causing the injury. The effectiveness of such devices in limiting only the motion which causes the injury is difficult to determine. The externally applied cloth ankle wrap is one such device which is thought to increase ankle joint stability and thus limit, to "some degree, plantar flexion and inversion. It is the combination of these two movements which are associated with the disruption of the lateral collateral ligament, resulting in a lateral ankle sprain. The purpose of this investigation was to study the effects of inversion forces applied to the ankle joints of cadavers and the resulting influence on talar tilt. The subproblem of this investigation was to examine the affects that an external cloth ankle support has on cadaver talar tilt when inversion forces were applied. Seventeen unpreserved cadaver ankle joints were used as subjects for this study. The limbs for the study had no history of previous injury and had not been subjected to any structural damage prior to experimentation. The seventeen cadaver limbs were examined by x-ray analysis under two test conditions, those being supported and unsupported. Each ankle joint was subjected to four regulated loads under each condition. X-ray photographs were taken at the time each force was applied. The limb testing took place within 24 hours postmortem. Attempts were made to test each ankle joint to failure under maximum loading conditions. The following hypotheses were tested for significance at the .05 level. 1. An increasing inversion force applied to the ankle joint of a cadaver produced increasing talar tilt in a plantar flexed foot position. 2. The application of an external cloth ankle support decreases the amount of talar tilt produced by inversion force in the plantar flexed foot. Preliminary analysis of variance revealed that there was a nonsignificant difference regarding the order in which the ankle joints were tested. Multivariate analysis of the data collected revealed that hypothesis #1 was supported at the 0.001 level and that hypothesis #2 was supported at the 0.002 level. No statistically supported conclusions could be drawn from the data collected from the maximum load conditions. / Education, Faculty of / Kinesiology, School of / Graduate
