Outcomes

Primary Outcome Measures

Change in pain intensity measurements using visual analogue scale
A scale form 0 to 10 points, a less score means improvement.
Change in hip flexion range of motion measurement using universal goniometer.
the therapist measures it for patients, an increasing value means improvement.
Change in knee extension range of motion measurement using universal goniometer.
the therapist measures it for patients, an increasing value means improvement.
Change in ankle dorsiflexion range of motion measurement using universal goniometer.
the therapist measures it for patients, an increasing value means improvement.
Change in lumbar flexion range of motion measurement using universal goniometer.
the therapist measures it for patients, an increasing value means improvement.
Change in functional disability measurement using the oswestry disability index.
An index indicating disability level, a less score indicates improvement.

5. Study Description

Brief Summary
This study compares between neurodynamic mobilization and stretching exercises in treatment of chronic dicogenic sciatica
Detailed Description
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. Their age ranged between 21-50 years. They were randomly allocated by simple random method; to avoid selection bias, patients were asked to choose a card of three wrapped cards representing the three treatment groups: Group (A): received Slider technique only. Group (B): received Tensioner technique only. Group (C): received Stretching exercises of back extensors, hamstrings and gastrocnemius muscles only.
