A flexibility intervention to reduce the incidence and severity of joint injuries among municipal firefighters.

The present study of 469 municipal firefighters examined the effect of flexibility training on the incidence and severity of joint injuries. Both flexibility measures and costs (lost time and medical care costs) were investigated in this study. Significant differences were found in flexibility scores of the experimental and control subjects with overall flexibility increased in the experimental group. Although incidence of injury was not significantly different for the experimental and control groups, injuries sustained by the experimental group resulted in significantly less lost time costs. Findings indicate that the flexibility training program had a beneficial effect on reducing the severity and costs of joint injuries in this firefighter population.
