Abstract
Context:  Neurodynamic tension affects hamstring extensibility and stretch tolerance, and is considered important in hamstring injury management. Neurodynamic tension was postulated to affect segmental muscle extensibility and stretch tolerance, and potentially also demonstrate extra-segmental and contralateral effects.   Objectives:  Assess the effects of a novel sciatic-tibial neurodynamic tension technique, the modified long sit slump (MLSS), on segmental, extra-segmental and contralateral muscle extensibility and stretch tolerance.  Study design:  Counterbalanced cross-over study.  Setting:  University research laboratory.  Participants:  Thirteen healthy and active subjects (mean±SD age 24±8 y, BMI 23.1±2.8 kg·m-2).  Intervention:  MLSS application (5 seconds, 5 repetitions, 3 sets) on two occasions with a three-week washout period, and either stance or skill leg treated in a counterbalanced manner.  Main outcome measures:  Segmental and extra-segmental muscle extensibility were measured utilising passive straight leg raise (PSLR) and prone knee bend (PKB) at pre-, immediately post- and one hour post-intervention. Stretch intensity ratings were measured utilising a simple numerical rating scale (SNRS).  Results:  MLSS significantly increased PSLR and PKB bilaterally (p
