Neurodynamics vs. Stretching in Soccer Players With Short Hamstring Syndrome

Study Overview
=================
Brief Summary
-----------------
Comparison of the effects of passive stretching vs. sciatic nerve gliding in soccer players presenting with short hamstring syndrome.

Detailed Description
-----------------
Soccer players from three teams in the region of Murcia (Spain) were recruited and randomly divided into three groups: control group, experimental group 1 and experimental group 2. In the control group passive shoulder mobilization will be applied, in experimental group 1 sciatic nerve gliding will be applied and in experimental group 2 passive hamstring stretching will be applied. Treatments will be performed once a week for 4 weeks and measurements will be taken at week 1 and 4.
