Brief summary
An emerging body of research has shown promising effects of exercise-based injury prevention programs (IPPs) in reducing knee injury risk. However, the efficacy of IPPs as reflected in clinical trials have not been replicated in real-world practice largely due to lack of compliance and implementation support. Individualized IPPs targeted to specific biomechanical components may provide the most prudent and effectual implementation strategy by specifically targeting high risk groups. However, the individualization process is hampered by the absence of field-based objective screening methods to stratify risk according to trunk dominance deficits, and a lack of consensus on the ‘best’ combination of IPP components. Thus, the objectives of this study are 1) to identify the best combination of field-based tests to screen for trunk dominance deficits, and 2) to explore the effects of an injury prevention program individualized according to trunk dominance screening results in reducing knee injury risk in athletes. Study hypotheses: 1) that field-based tests for trunk dominance deficits are a valid and reliable alternative compared to three-dimensional biomechanical motion analysis; 2) that individualization of IPPs are more effective in decreasing trunk dominance deficits than generic IPPs
Interventions
Exposure group will perform their usual warmup, followed by 10 mins proximal stability training at the end of the training session.
These exposures will occur during warm-up at bi- or tri-weekly club training sessions, for 8 weeks. The 8-week intervention will be supervised by the coaching staff. There will be a training session prior to commencement of intervention by a Australian Health Practitioner Regulation Agency registered Physiotherapist. The mode of administration will be in a group of
Exposure group will perform their usual warmup, followed by 10 mins proximal stability training at the end of the training session. These exposures will occur during warm-up at bi- or tri-weekly club training sessions, for 8 weeks. The 8-week intervention will be supervised by the coaching staff. There will be a training session prior to commencement of intervention by a Australian Health Practitioner Regulation Agency registered Physiotherapist. The mode of administration will be in a group of 12-20 players per age group depending on club training policies. Proximal stability training consists of 6 exercises in the following categories - trunk flexion, lateral trunk flexion, prone trunk stability, single-leg anterior stability, single leg lateral stability, single leg rotatory stability at the end of training. that are based on previously published reports and pilot work. Specific information on the exercises, recommended intensities, sets, and repetitions may be found in this paper - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2586107/ The exercises are self-limiting, and participants should perform them with optimum technique and/or to technical failure depending on the type of exercise. There will be no prescribed level of intensity. If the participant fatigues to a point that they can no longer perform the exercise with near-perfect form, or displays a sharp decline in proficiency, then they will be instructed to stop. The intensity of these exercises are not intended to match the intensity at which the control group will be performing their drills, and vice versa. Adherence will be monitored through club attendance log managed by respective managers and coaches of each age group. They will be overseen by club technical director and research team.
