Effective evidence-based intervention strategies are essential to reduce MSKI incidence, and research has shown the positive effect of both nutritional interventions and physical training (PT) interventions on reducing MSKI incidence. Levels of vitamin D metabolites have been associated with MSKI and bone stress fracture risk, while calcium and vitamin D supplementation has been shown to reduce the incidence of stress fractures during military training. Protein and carbohydrate supplementation during arduous military training (high volume, high intensity) has also been shown to reduce MSKI risk and the number of limited/missed duty days. PT has played a key role in soldier development to meet the occupational demands of serving in the armed forces. Paradoxically, while PT is fundamental to enhancing soldier readiness, PT can also be a major contributor to MSKI; emerging evidence suggests that the nature of the PT being performed is a risk factor for MSKI. However, strategies like reducing training load and implementing PT programmes using evidence-based training principles can reduce MSKI incidence among military service members by 33-62%, and reduce the financial burdens for military services. This review provides a summary of effective MSKI reduction interventions and provides strategies to enhance the success and adoption of such interventions.</p>","PeriodicalId":48485,"journal":{"name":"Bmj Military Health","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142113559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spinal immobilisation can be costly in terms of time and personnel required to apply and sustain it. C-spine 'clearing' tools frequently do not apply to the blast-injured casualty, so clinical judgement must be used to determine those requiring c-spine immobilisation. This will be strongly influenced by the likelihood of such an injury, but currently, the incidence of c-spine injury in dismounted blasts is not known.</p><p><strong>Methods: </strong>We searched PubMed, EMBASE and the Cumulative Index to Nursing and Allied Health for original research reporting the number of patients suffering c-spine injury as a result of the dismounted blast, as well as indices of injury severity such as incidence of limb amputation.
