This study examined acute systolic (SBP) and diastolic (DBP) blood pressure responses within passive and modified proprioceptive neuromuscular facilitation (PNF) stretching techniques. Nonhypertensives (N = 60) were assigned to one of three treatment groups. Group 1 employed an antagonist passive stretch (APS), 6-sec maximal voluntary isometric contraction (MVIC) of the antagonist, and subsequent APS. Group 2 employed an APS, a 6-sec MVIC of the antagonist, submaximal concentric contraction of the agonist, and APS. Group 3 was similar to Group 2, with the deletion of an MVIC prior to the concentric contraction. Blood pressures were obtained during rest, baseline following passive stretch, and at the end of the three phases of the PNF technique. Range of motion (ROM) data were collected for baseline and treatment in terminal hip flexion for each group. All PNF treatments were effective for increasing ROM. One or two trials of PNF improve ROM and avoid increasing SBP, while a third trial increases SBP.
本研究检测了被动和改良型本体感觉神经肌肉促进法（PNF）拉伸技术过程中的急性收缩压（SBP）和舒张压（DBP）反应。将非高血压患者（N = 60）分为三个治疗组之一。第1组采用拮抗肌被动拉伸（APS）、拮抗肌6秒最大自主等长收缩（MVIC）以及随后的APS。第2组采用APS、拮抗肌6秒MVIC、主动肌次最大向心收缩以及APS。第3组与第2组相似，但在向心收缩之前删除了MVIC。在静息时、被动拉伸后的基线以及PNF技术三个阶段结束时测量血压。收集了每组终末髋关节屈曲基线和治疗时的活动范围（ROM）数据。所有PNF治疗均能有效增加ROM。一到两次PNF试验可改善ROM并避免SBP升高，而第三次试验会使SBP升高。
