Injury Mechanisms, Activities, and Limited Work Days in US Army Infantry Units.

Injuries are a leading health and readiness concern for the US Army. For effective prevention planning, details concerning circumstances associated with injuries are needed. Over 5,000 Soldiers were surveyed to collect demographic and injury details (type, body part, mechanism, activity, limited duty days); 874 reported an injury within 6 months of survey administration. The greatest proportion of limited duty time was associated with knee (19.2%), ankle (14.8%), and lower back injuries (12.9%). Overexertion was the leading injury mechanism (43.9%), followed by falls, jumps, trips, and slips (35.2%), which accounted for the highest average limited duty days per injury (42±43 days). Running was the leading activity associated overexertion injuries (39.3%) and falls (30.5%). Running also accounted for the greatest total limited duty days (5,844 days, 29.8%). For Army infantry units, results suggested a focus of prevention activities on running-related injuries resulting in overexertion or falls. Healthcare providers can facilitate injury prevention with contributions to initiatives providing details on injury mechanisms and activities associated with injuries.
