Module 8 — Practical Scanning Technique
The hands-on craft: positioning, reading the legs accurately, and avoiding the classic mistakes.
- Correct patient and practitioner positioning
- Handling the feet and reading leg length reliably
- The common causes of misdiagnosis and how to avoid them
- Rebalancing, polarising the three body planes, and finishing a session
8.1 Positioning
The patient lies supine, straight on the table, arms relaxed at the sides, legs together and not crossed. The practitioner stands or sits at the foot of the table, squarely centred on the midline, so both legs are viewed symmetrically. A crooked patient or an off-centre practitioner is the fastest route to a false reading.
8.2 Shoes, and handling the feet
Shoes are normally removed so the reference line is clean (some lineages scan with shoes on for specific reasons, but consistency is what matters). Cup the feet gently and symmetrically — equal, light pressure on both — and bring the medial malleoli or heels to a common line. Do not pull or twist; you are observing a reflex, not forcing a measurement. Re-set the feet to the same neutral start before each read.
8.3 When the legs are unequal from the start
If the legs look unequal before any scanning, first rule out simple causes — posture on the table, a twisted pelvis, clothing bunched under one hip. In the model, a starting asymmetry can indicate a global imbalance that is addressed with a rebalancing pair (a “Goiz pair” used to reset the body) before detailed scanning. Establish an even baseline first; otherwise every later read is measured against a crooked ruler.
8.4 Common causes of misdiagnosis
- Examiner movement — leaning, shifting, or unequal hand pressure creates apparent length changes. Keep your stance and grip identical between reads.
- Off-centre patient — re-square the body.
- Metal or electronics left on the client or table interfering with the magnet.
- Suggestion and expectation — the reflex is easily biased; stay neutral and don’t telegraph what you expect to find.
- Fatigue — tired eyes miss small differences; work methodically.
Be aware that mainstream examiners attribute the leg-length change itself to exactly these factors — posture, pressure and suggestion — rather than to detecting disease. Rigorous technique is what keeps your own readings consistent; it does not, on its own, validate the underlying claim. Hold both facts honestly.
8.5 Polarising the three body planes
Advanced teaching describes polarising the three planes of the body (for example working key reference points so the sagittal, coronal and transverse relationships read consistently) as a way to stabilise the field before detailed scanning. Learn this after you are fluent with the basic sweep; done too early it just adds variables.
8.6 Finding the second pole, and fast complete scanning
Once the scanning magnet flags a point, search efficiently for its partner by testing the likely complementary regions from the known pair map rather than sweeping blindly — the Pairs Atlas and Scanning Routes tell you which partners to expect. With practice the whole body can be swept quickly and reproducibly: a fixed route, identical technique on both sides, and a disciplined re-scan at the end.
8.7 Fixing, removing and storing the magnets
Hold impacting magnets in place with masking tape so your hands stay free. Remove magnets deliberately at the end — lift cleanly, keep opposite poles from snapping together near the skin, and re-check the reflex after removal. Store the working set with poles separated or keepered, colours clearly marked, away from cards and devices (Module 4).
You’ve completed the curriculum
You now have the theory, the poles, the magnets, the pairs, the protocol and the hands-on technique. Spend your time next in the Reference Library — learn the routes, study the common pairs, and practise a clean, consistent scan. Revisit Module 7’s precautions often.
