  The pelvis is stabilised by form closure and force closure, and becomes unstable when these fail

  The sacroiliac joint is stable only when bony form (form closure) and muscular and ligamentous tension (force closure) engage together. When that closure fails, pelvic instability and pain follow.

  Nerves, like joints, must glide and tension in order to function normally

  Nerve sliding and tensioning were systematised for clinical use. Where neural mobility is reduced, entrapment and symptoms follow.

  Placing a segment in a position of ease switches off muscle spindle hyper-excitability and tension releases

  An indirect technique that places the tender point in its most comfortable position to reset abnormal muscle spindle signalling.
