Abstract
The purpose of this Academic Exercise was firstly to provide a descriptive kinematic analysis of the sidestep cutting manoeuvre to allow a better understanding of this action which has been associated with injuries, and secondly, to identify whether the use of prophylactic taping is in fact altering the kinematic pattern such that despite protecting the ankle joint, the risk of injury to the knee joint may be increased.
Eleven healthy male university and/or club representatives (mean age = 25.05 ± 3.91 years) were selected from the School of Physical Education (SPE), National Institute of Education, Nanyang Technological University, Singapore and the Singapore Rugby Union (SRU) to perform a sidestep cutting manoeuvre under non-taped (for descriptive purposes) and taped conditions (effects of ankle taping). Kinematic data was collected using the Peak Motus Motion Analysis System with results analyzed under the three phases, namely, foot plant, during contact and toe-off.
Descriptive results showed that the foot was abducted and everted with an extended knee rotated lateral relative to the foot at foot plant. During contact, the foot moved through a range of adduction and eversion with the knee flexing. At take-off, the foot was at a neutral position with the knee extended and hip adducted.
The foot plant and toe-off positions of the sidestep cutting manoeuvre predisposed the athlete to possible anterior cruciate ligament (ACL) injuries with anterior and rotational forces loaded throughout the lower limb when the knee is in an extended and abducted/adducted position. Given that the foot was already everted at foot plant, the impact forces could not be attenuated and thus, may have been transmitted the forces up the closed kinetic chain of the foot-leg-thigh, thus increasing the risk of injury at the knee too.
For the second part of this Academic Exercise, ankle taping did not significantly affect the kinematic variables analyzed during the sidestep cutting manoeuvre and thus could not be seen to increase the risk of knee injuries based on current findings. It is however recommended that future studies include kinetic data and a large sample size.
