Effects of an ergonomic program on the quality of life and work performance of university staff with physical disabilities: A clinical trial with three-month follow-up.
Disability and Health Journal 2018 July 19
BACKGROUND: Problems related to physical disability may have an extremely negative impact in the work environment, reducing productivity and contributing to health problems and a worsening quality of life.
OBJECTIVE: To assess the effects of an ergonomic intervention program on the quality of life and the work performance of people with physical disabilities working in a university environment.
METHODS: A pilot clinical trial with three-month follow-up was conducted at the Physiotherapy Clinic of the Federal University of Paraíba (Brazil). Eight workers at the university took part in an ergonomic adjustment (using ErgoDis/IBV software) and physiotherapy program at their workplace for twelve weeks, in two 60-min sessions per week. The measuring instruments used were the WHOQoL-BREF questionnaire for quality of life and the Work Ability Index for work ability. A repeated-measures ANOVA analysis and Wilcoxon signed-rank test were also performed.
RESULTS: Significant intra-group changes were observed in the QoL subscales for the physical dimension (F = 5.487, p = 0.017) and the environment dimension (F = 7.510, p = 0.006). The post-treatment analysis revealed significant changes for both the physical dimension (Z = -2.552, p = 0.011) and the environment dimension (Z = -2.201, p = 0.028). After the three-month follow-up period, only the environment dimension recorded a significant change (Z = -1.965, p = 0.049). The effect sizes were large. Regarding work ability, the repeated-measures ANOVA analysis showed a significant time effect (F = 5.067, p = 0.022), with large pre-post treatment improvement (Z = -2.555, p = 0.011, d = 0.914).
CONCLUSIONS: The program based on ergonomic and physiotherapy program greatly enhanced the subjects' quality of life and work ability.
