Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Neurodynamics
Neurodynamics
Subjects in the neurodynamic group performed the 'Seated Straight Leg Slider' (SSLS) (Fig.1). To execute this sliding technique, subjects assumed a seated slump position (thoracic and lumbar flexion) which they needed to maintain throughout the exercise. This SSLS consisted of alternating movements towards knee extension and ankle dorsiflexion (increase of neural tension) combined with cervical extension (decrease of neural tension) on one hand, and knee flexion and ankle plantar flexion (decrease neural tension) combined with cervical flexion (increase of neural tension) on the other. During this 6-week period, each subject in this neurodynamic slider group was instructed to perform 3 sets of 20 repetitions on a daily basis for 6 weeks.
Static stretch
Static stretch
Subjects in the control group were instructed to perform a standard standing static stretch with the heel of the dominant leg taking support on a chair. Then they had to move the pelvis into anteversion, simultaneously inducing a forward lean of the trunk, until the clear sensation of hamstring stretch was perceived at the posterior aspect of the thigh. Again, the execution of the exercise was thoroughly explained and evaluated by the researchers and subjects sent home with a comprehensive instruction guide and supporting pictures. Each subject was instructed to do 3 repetitions of 30 second static stretches on a daily basis during the 6-week intervention.
