objective of this randomized controlled trial is to examine the efficacy of both tensioner and slider neurodynamic approaches in patients suffering from sciatica. This study seeks to establish which approach is more efficacious in alleviating pain intensity, disability functional, and mobility. The results of this study will assist physical therapists in making an informed decision on the type of neurodynamic therapy for their patients.

Due to the increasing prevalence of sciatica and evidence based treatment options using physiotherapy that offers effective alleviation of pain and rehabilitation of function. Neurodynamic mobilization focuses on addressing neurological problems; thus, there is a need to know about the effectiveness of the different types of the technique being used.

The current research is expected to contribute to the existing literature in the area of physiotherapy concerning the identification of the most effective neurodynamic technique in the case of sciatica. These findings could be helpful for medical practitioners during their work, making decisions and planning treatment. At the same time, the results of the investigation may become the basis for further research.
