Effects of Slider, Tensioner Neurodynamic Mobilization Techniques and Stretching Exercises in Treatment of Chronic Discogenic Sciatica: A Comparative Study

Résumé

Abstract Background: Sciatica is a critical musculoskeletal disorder affecting many people and its related disabilities disturb their lives. Methods: The study purpose was to see which one of two neurodynamic techniques and stretching exercises has a better effect on improving symptoms and dysfunction for cases of sciatica due to disc herniation. There were 36 unilaterally affected participants. They were assigned at random into three groups; participants in the first were treated by the slider technique, while participants in the second were treated by the tensioner technique, and participants in the third were treated by stretching. The treatment program was set to be 6 successive sessions in 2 weeks. The therapist assessed the participants pre and post-program.Results: The statistical analysis revealed that there were significant differences in favor of the slider and tensioner techniques compared with stretching. Furthermore, there were found significant differences in favor of the slider as compared to the tensioner technique regarding range of motion (ROM).Conclusion: Slider and tensioner techniques have better clinical results than stretching exercises in improving symptoms and dysfunction with a greater effect for the slider technique in enhancing ROM.Trial registration: This study was executed under the ethical guidelines of 1964 declaration of Helsinki and was registered in the clinical trial registry with clinical trial.gov on 10/02/2021, ID: NCT04746690.
