Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial

Two recruit intakes allocated by Army into two groups per intake.
Cluster randomised into intervention and usual training groups.
Computer randomisation per group by a person unrelated to study.
Result concealed in envelop and handed to head Physical Training Instructor for distribution. to Physical Training Instructors of each study group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple computer randomisation A or B then 1 or 2
One group was intervention, the other usual training.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
Intervention assignment
Parallel
Other design features

Type of endpoint/s
Efficacy
Statistical methods / analysis
The effect of the neuromuscular training program will be examined using one-way ANOVA comparisons of primary and secondary outcome measures between the experimental and control groups. Multiple linear regression analysis will be utilised to determine the influence of biometrics and other participant characteristics on treatment response.

As a direct consequence of working within the constraints of an Army training environment we were required to examine a convenience sample of 2 intakes (8 platoons) compromising approximately 280 soldiers.

Summary
Brief summary
The primary aim of this study is to investigate if the introduction of a 6 week neuromuscular training program compared to usual physical training results in fewer lower limb injuries in New Zealand Army recruits during basic training.
A secondary aim will investigate if a 6 week neuromuscular training program compared to usual physical training results in fewer health care encounters and lower health care costs from injuries sustained during basic training.

It is hypothesised, that during basic training, recruits participating in the intervention compared to the usual training group will have:
i) fewer lower limb injuries; and
ii) fewer health care provisions and lower costs for injuries sustained.

Study design: cluster randomised controlled trial.

The intervention consists of a 6-week neuromuscular training program involving a light run warm up and a circuit of 14 plus exercises that include strength, technique, core stability, motor control and plyometric training performed at low to moderate intensity. The neuromuscular training intervention exercises are administered by 2 qualified and experienced Army Physical Training Instructors trained by a physiotherapist. Exercises are performed 3-5 sessions per week which was determined by the existing physical training schedule.
Usual training involved running based warm up exercises performed at low to moderate intensity and 3 -5 sessions per week..
