The role of quickness, adjustive amplitude, preadjustive tension, and countertension in facilitating joint distraction to cavitation is investigated. These characteristics are further shown to contribute to joint isolation, protection of joints from injury, and enhanced adjustive efficiency. Block and spring "slinky dog" models aid in illustrating the physics principles involved. The complete role of mass and acceleration in the adjustive process is discussed.
研究了速度、调整幅度、预调整张力和反张力在促进关节牵张至关节腔形成中的作用。这些特性进一步表明有助于关节隔离、保护关节免受损伤以及提高调整效率。滑轮和弹簧“弹簧狗”模型有助于阐明其中涉及的物理原理。讨论了质量和加速度在调整过程中的完整作用。
