An injury of the ACL is a devastating injury which commonly occurs in sports with a lot of jumping, accelerations and decelerations.1 Ideally, ACL injury prevention programs achieve long-term effects due to improved movement patterns on the field that translates to reduction of ACL injury incidence. For effective ACL injury prevention, learned motor skills needs to become relatively permanent after a certain time interval when no feedback, guidance or instructions are given. Retention of movement technique is crucial in anterior cruciate ligament (ACL) injury prevention programs. It is unknown if specific instructions or video instructions result in changes in kinematic and kinetic measures during a relatively short training session, and in a retention test one week later. The purpose was to determine the effects of verbal external focus (EF), verbal internal focus (IF) and video instructions (VI) on landing technique (i.e. kinematics and kinetics) during training and retention.
Males and females in the EF and VI instruction group showed beneficial results during and after the training session, in terms of improved landing technique. Retention was achieved after only a short training session.
ACL injury prevention programs should include EF and/or VI instructions to improve kinematics and kinetics and achieve retention. #winner 🏆 #bestoriginalresearch #sportsphysicaltherapy #preventionACL 🔝👍🏼
