This study was conducted at the outpatient clinics, faculty of physical Therapy, Kafrelsheikh University to compare between the effects of slider, tensioner neurodynamic mobilization techniques and stretching exercises on pain, Range of motion (ROM) and functional disability for patients with chronic discogenic sciatica.~Design of the study:~A pre-test post-test three-armed comparative study design was used for comparison between the effects of slider, tensioner neurodynamic mobilization techniques and stretching exercises for patients with chronic discogenic sciatica.~Selection of patients:~Sample size:~Using G-power software program and regarding F test study , alpha level of 0.05, confidence interval 95% and effect size of 0.25 (to detect small effects ), three groups and 6 dependent variables, the total sample size will be 36 patient (twelve in each group).~To reach the specific sample size, forty-three patients were screened regarding the inclusion/exclusion criteria. Thirty-six patient with unilateral chronic discogenic sciatica from both sexes (….male and … female) were recruited from the outpatient clinics, faculty of physical Therapy, Kafrelsheikh University.
