Introduction: One of the causes of low back pain is lumbar hyperlordosis. There are different therapeutic exercise protocols for its correction that do not involve all body segments. A modified protocol (Pérez-Olmedo) that involves all body segments is proposed. Objective: To evaluate the effectiveness of the proposed protocol compared with two established protocols for lumbar hyperlordosis correction. Methods: A simple- blinded clinical trial was carried out on 42 medical school students fro m the Universidad de Colima. Pérez-Olmedo, Williams and Jeffrey Saal protocols were randomly assigned. Clinical and radiological evaluations were done. Lumbar hyperlordosis was considered to be present when Ferguson’s angle was > 30°, measured by lateral spinal x-rays. Students underwent directed and supervised exercise sessions for two months. Improvement of hyperlordosis correction with each protocol was compared using the paired Student t test and ANOVA. Results: Mean age was 18 + 0.9 years. Hyperlordosis frequency was 31% (n = 15). At the end of the study there was no significant difference in mean Ferguson’s angle comparison among the three treatment groups. There was hyperlordosis improvement in the following percentages: Group A = 60%, Group B = 16% and Group C = 0%. Conclusions: The proposed exercise protocol (Pérez-Olmedo) may be an alternative for lumbar hyperlordosis improvement in asymptomatic youths.
