To evaluate the effectiveness of prefabricated foot orthoses for the prevention of lower limb overuse injuries in naval recruits.
This study involved a randomised controlled trial of . Three-hundred and six participants aged 17–50 years. They all undertook 11 weeks of initial defence training at the Royal Australian Navy Recruit School (Cerberus, Australia) They were then split into a control group who wore flat insoles and an intervention group who wore prefabricated foot orthoses.
They Looked for the incidence of medial tibial stress syndrome (shin splints), patellofemoral pain, Achilles tendinopathy and plantar fasciitis/plantar heel pain during the 11-week training period.
Sixty-seven injuries (21.9%) were recorded. The all together the recruts group sustained 67 injuries. The flat insoles had 40 injuries (26.1%) and the orthotic group 27 (17.6%) injuries,
This means there was a 34% reduction in risk of developing medial tibial stress syndrome, patellofemoral pain, Achilles tendinopathy or plantar fasciitis/plantar heel for the orthotics group compared with the flat insole group.
Foot orthoses may be beneficial for reducing the incidence of lower limb injury.
