Abstract
Background: Low back pain is considered a frequent musculoskeletal disorder, generating limitations to perform daily activities and states of disability. The objective is to establish the effectiveness of the Proprioceptive Neuromuscular Facilitation (PNF) technique in reducing lumbar pain of workers in dairy factories. Methods: a comparative study among longitudinal cohort groups was carried out. 25 participants were divided into two groups. PNF was applied to group A (n=13) and group B that was the control group (n=12). An initial evaluation was done and 12 weeks after the intervention a final evaluation was done. Pain intensity, the index of disability associated with back pain (BP) and quality of life were measured. Results: after 12 weeks of application of the protocol, the PNF technique significantly decreased pain intensity, improved functional disability associated with lumbar pain and quality of life with respect to health (p<0.005). For the control group there were no differences in the variables before and after the protocol was applied. Conclusions: The application of FNP in dairy factory workers is effective in reducing pain, disability associated with non-specific lumbar pain and improving the quality of life.
