'Percieved hamstring tightness' is a common complaint in patients with lower back, buttock and posterior thigh pain. Wether this tightness originates from reduced tissue extensibility to altered neural mobility can be determined with tests such as the passive knee extension, active knee extension, passive straight leg raise and slump tests. Treatments targeting an improving neural tissue mobility and address pathoneuromechanics have been shown to be more effective in reducing hamstring tightness, than the more tradition passive/active static hamstring stretches.
