Height and in-flight low back pain association among military helicopter pilots.

摘要: Introduction Low back pain (LBP) among helicopter pilots is a well-recognized problem, with prevalence ranging from 61 to over 80%. Studies indicate association total flight hour (TFH) exposure and lack of height or body mass index (BMI); however, those that have excluded injuries unrelated flying are limited. Methods Surveyed regarding LBP were 1028 U.S. Navy pilots. Of the 648 (63%) respondents, 83 pilots, 12.9%, who reported nonflying related without necessary data excluded, yielding N = 554. Case-control analysis was performed logistic regression for height, BMI, TFH on significant (defined as > 30% each flight) presence versus absence Chi-square median split ANOVA include airframes. Results Height positive predictor all subjects (OR: 1.7), strongest male 2.1). THF, airframe (H-60, TH-57, H-53, H-46) not associated. Discussion These results imply ergonomic stressors adversely impact lumbar symmetry may be predominant factor in during flight. Significant rates persist design enhancements mitigate these stressors. in-flight studied TFHs, not. For every 1" increase pilot values, odds experiencing increased by 9.3%, equal/taller than (71 in.) having twice compared shorter.
