Fig. 5From: In vivo measurement of intradiscal pressure changes related to thrust and non-thrust spinal manipulation in an animal model: a pilot studyIDP during 30° of motorized flexion with and without manual contact. Intradiscal pressure (IDP) recordings from the L4-L5 disc during motorized flexion of 30° without manual contact (A) and with manual thumb contact applied cranialward to the L4 spinous (B). Note the additional ~ 1.4 kPa decrease in IDP with applied physical contactBack to article page
