Multicomponent exercises to prevent and reduce back pain in elderly care nurses: A randomized controlled trial

Abstract

Background Sports science is making an important contribution to health services research and supports the development of tailored interventions, e.g., in nursing settings. Working in elderly care is associated with a high prevalence of low back pain (LBP). Due to the diverse requirements and high strains, multicomponent programs are essential to address all relevant factors. This randomized controlled trial investigated the effects of a tailored ten-week ergonomics and twelve-week strength training on lifting behavior (Progressive Isoinertial Lifting Evaluation (PILE-Test)), strength endurance (Biering-Sørensen-Test), LBP (Visual Analog Scale, VAS), functional impairment (Oswestry Disability Index (ODI)) and adherence (self-developed questionnaire). Methods n = 42 nurses were randomly assigned to the intervention (n = 20) or control group (n = 22). The data were collected at baseline, at ten weeks (after ergonomics training), at 22 weeks (after strength training), and at 34 weeks (follow-up). Group differences were analyzed by Chi2-Tests, ANOVA, and Linear Mixed Models. Results The intervention group showed an improved lifting performance (PILE-Test; 95% CI, 1.378–7.810, p = .006) and a reduced LBP compared to the control group (VAS; 95% CI, -1.987-0.034, p = .043) after ergonomics training (PILE-Test, F (1,34) = 21.070, p < .001; VAS, F (1,34) = 5.021, p = .032). The results showed no differences concerning the Biering-Sørensen-Test and the ODI. Positive adherence rates were observed. Conclusions This approach and the positive results are essential to derive specific recommendations for effective prevention. The study results can be completed in future research with additional strategies to reduce nurses’ burden further.
