How the OS Test Works: Passive Muscle Testing

Every adjustment I make is guided by a test. Before I correct anything, I want to know exactly which structure is holding stress and in which direction. The tool I use for that is the OS Test.

Active and passive muscle testing

Many muscle testing methods are active. You push against the practitioner’s hand, and they judge whether the muscle holds.

The OS Test is passive. You lie relaxed on the table while I challenge a structure in a specific direction and watch how your leg length responds. You do not have to push or hold anything, so you do not tire, and I can check many structures in a single visit.

What it tells me

The response tells me whether a structure is involved and which direction it needs. That can be a vertebra, a rib, a disc, a ligament, a muscle, the jaw or a bone of the skull. Once I know that, the correction can be small and specific. There is no need for force.

Progressive visits

Each visit builds on the last:

• First visit. A full assessment and correction of the main pattern.
• Second visit, 1 to 2 weeks later. I check what held and address the next layer.
• Third visit, about four weeks later. I see how the work holds up under normal life.
• After that. maintenance care, monthly at most and stretching to every 6 to 8 weeks.

Fewer visits means less time and money spent on appointments, and it is the whole point of testing carefully first.
