About the author<\/strong> \u2014 FOOTWORK LAB is a manufacturer of foot assessment equipment and custom orthotic insoles, based in Ruichang, Jiangxi Province, China. Founded in 2014, with its own production plant since 2018. Certified to European Union and ISO quality system standards. See the factory<\/a> or view certification<\/a>.<\/p>\n<\/div>\n

Clinics rarely fail at orthotic scanning because the equipment is bad. They fail because the routine around the equipment was never written down.<\/strong> One practitioner captures the patient after a five-minute chat; another captures after twenty. One asks the patient to walk at their normal pace; another lets them walk the way people walk when they know they are being watched. The recordings look similar on screen and mean different things, and six months later nobody can tell which is which.<\/p>\n

This article sets out the steps that decide whether a recording is usable \u2014 usable meaning comparable, repeatable and clear enough that a production team can build from it without a phone call. FOOTWORK LAB manufactures foot assessment systems that capture plantar pressure and posture, and produces custom orthotic insoles from the resulting briefs, in our own plant in Ruichang, Jiangxi Province.<\/p>\n

Most buyers arrive at this subject searching for orthotic scanning or 3D foot scanning, because those are the phrases the market uses. What the phrases describe, in a working clinic, is a capture routine: a defined sequence, performed the same way each time, stored so that it can be found again.<\/p>\n

What orthotic scanning covers in practice<\/h2>\n

In trade usage, orthotic scanning describes the data capture that precedes an insole build. It is usually understood to include the shape and contact area of the foot, the distribution of load across the sole, and some record of lower-limb alignment. Different systems divide that work differently, but a brief built from any of them needs all three in some form.<\/p>\n

The shape question is the one buyers think of first, because the phrase suggests a mould. The load question is the one that changes the build most, because an insole is a device for redistributing force, and force is what a pressure recording shows. The alignment question explains why the load looks the way it does.<\/p>\n

A clinic that captures only shape tends to produce insoles that fit well and do little. A clinic that captures load and alignment as well produces briefs with reasons in them, which is what makes a second pair possible without re-assessing from scratch.<\/p>\n

Before the first capture: room, routine and consent<\/h2>\n

The room matters more than it sounds. The patient has to walk naturally, which means a clear path of several steps in both directions, with no need to turn sharply at the end. A platform placed in a corridor where the patient has to stop and pivot every three steps produces recordings of a turning foot, not a walking one.<\/p>\n

Lighting matters for the posture views. Camera-based capture needs even light and a plain background; a window directly behind the patient turns the silhouette into a outline and the alignment view into guesswork. A screen or a marked floor position solves this in most rooms and costs nothing.<\/p>\n

The routine should be written and posted where the operator can see it: which foot first, how many passes, whether shoes and socks come off, where the patient stands between passes, and what is said to them before the first step. Written routines survive staff changes. Remembered routines do not.<\/p>\n

Consent and record keeping belong here too. The patient should know what is being recorded, why, who will see it and how long it is kept. That is a data protection matter in most markets and a trust matter everywhere, and it takes one sentence at the start of the appointment.<\/p>\n

Static capture: stance, landmarks and the first check<\/h2>\n

Static capture records the foot at rest, bearing weight. The patient stands in a defined position, feet at a natural width, looking forward rather than down, and stays still long enough for the recording to stabilise. The output is a contact map: where the sole meets the ground, and where load concentrates.<\/p>\n

Two checks belong at this point, before anything else is recorded. The first is that both feet are positioned symmetrically relative to the platform. The second is that the patient is standing, not leaning \u2014 hands out of pockets, weight evenly distributed, no shifting. A static recording taken while the patient is still settling produces a map of a moving foot.<\/p>\n

Landmarks are the second part of the static stage. Heel position, the line of the Achilles, the position of the medial arch and the metatarsal heads all need to be identified in a consistent way, because the brief references them. If one operator marks the first metatarsal head at the joint and another marks it at the skin crease, the briefs will differ by more than the feet do.<\/p>\n

Then the footwear record. Internal length, whether the sock liner is removable, the condition of the heel counter and the wear pattern on the outsole. Four items, recorded in a minute, that explain most fitting problems later.<\/p>\n

Dynamic capture: the walking passes<\/h2>\n

Dynamic capture is where the useful information lives and where consistency is hardest to hold. The patient walks across the platform at their normal pace, several times, and the system records the sequence of contact and load for each pass. The operator’s job is to make each pass comparable to the last.<\/p>\n

Three variables need controlling. Pace is the first: patients speed up when they feel observed and slow down when they are unsure. The instruction should be to walk as they would to a shop across the road, and the operator should watch the first pass to confirm it looks natural before recording the rest.<\/p>\n

Foot placement is the second. A pass that lands half on the platform produces a partial map, which is worse than no map because it looks complete. Most systems allow the operator to discard a bad pass; the routine should say to do so rather than to average it in.<\/p>\n

The third is repetition. One pass is an anecdote. Several passes give a pattern, and the pattern is what the brief is built on. Where left and right differ across passes, that difference is itself information, and it should be noted rather than smoothed away.<\/p>\n

Posture views from the front and the rear<\/h2>\n

Camera-based posture capture adds the half of the picture that a pressure platform cannot see. From behind, the relationship between the heel, the Achilles line and the lower leg shows how the foot is being loaded from above. From the front, knee position and the line of the legs show whether one side is carrying more than the other.<\/p>\n

The captures should be taken in the same stance the patient uses for the static recording, and again during movement if the system supports it. Consistency between the two is what allows a clinician to compare them; a rear view taken standing and a front view taken walking are two different examinations.<\/p>\n

Mark the floor position once and leave it marked. A taped footprint on the floor is the cheapest quality control measure in the room, because it removes the operator’s judgement about where the patient should stand.<\/p>\n

Naming, storage and retrieval<\/h2>\n

A recording that cannot be found is a recording that did not happen. The naming convention should be decided before the first patient, not after the hundredth, and it should include the patient identifier used by the clinic, the date and the type of capture. Sorting by date alone is not enough once a clinic has more than one practitioner.<\/p>\n

Storage should be in one place with a backup, and it should survive a change of computer. Clinics that keep recordings on the machine in the assessment room discover the problem when that machine is replaced. Records that live in the system’s own library, exported on a schedule, are safer.<\/p>\n

Retrieval is the test. Ask a colleague who did not take the recording to find it, open it and read the brief, without help. If they cannot, the convention is not working, and the next reorder will involve a fresh assessment that did not need to happen.<\/p>\n

What unusable data looks like<\/h2>\n

Unusable data rarely announces itself. It looks like a complete recording with a plausible map. The signs are recognisable once you know them: a contact map with an abrupt straight edge where the patient stood on the border; a dynamic sequence where both feet produce identical traces because the pass was too fast to resolve; a posture view where the patient is rotated rather than the camera; a brief with no footwear record.<\/p>\n

The most common cause is haste. A capture squeezed into a short appointment produces data that passes the eye test and fails the comparison test. The second most common cause is a change in routine that nobody wrote down: a new platform position, a new instruction to the patient, a new member of staff trained by watching rather than by reading.<\/p>\n

The remedy is a periodic audit. Once a month, pull five recordings at random and check them against the written routine. It takes twenty minutes and catches drift before it becomes a batch of insoles built on inconsistent briefs.<\/p>\n

There is a cheaper version of the same test, and it is worth running monthly. Take two recordings from the same patient on different days and put them side by side without labels. If a colleague cannot tell which is which, the routine is holding. If one shows a broader contact area or a different load sequence, something changed between the two appointments, and the cause is almost always procedural rather than physiological.<\/p>\n

Operator training is the other half. Most clinics train the first operator properly and every subsequent operator by watching. The second-hand version of a routine drops the parts that look unimportant \u2014 the sock note, the discarded pass, the footwear photograph \u2014 and keeps the parts that look technical. Six months later the recordings are consistent within one practitioner and inconsistent across the team, which is the hardest kind of inconsistency to notice from inside.<\/p>\n

A short refresher, once a year, against the written routine closes most of that gap. It does not need to be a course. An hour with the printed steps, a volunteer patient and a comparison of the resulting recordings is enough to expose drift, and it costs less than one re-made pair.<\/p>\n

One last point on the handover. Ask the factory what it will do if the brief and the recordings disagree. A production team that builds to the written brief without checking, or checks without telling anyone, will produce a pair that matches one document and contradicts the other. The useful answer is a question back to the clinic before the material is cut.<\/p>\n

Handover to production<\/h2>\n

The handover document is the bridge between the clinic and the factory. It should state the build in terms production can hold: shell material, thickness range, geometry of the arch fill, heel cup depth and extent, cushioning layer and position, top cover, and the footwear the pair is intended for.<\/p>\n

Attach the recordings. A brief without the data behind it is an opinion, and a factory receiving an opinion will either guess or ask questions. Both cost time. A brief with the data attached can be checked against the source, which is how a production team catches an inconsistency before it becomes a re-make.<\/p>\n

Where the clinic and the factory are the same organisation, this is straightforward. Where they are not, the handover document is the contract. It should be short, specific, and written in language both sides use the same way \u2014 which usually means naming materials and geometry rather than adjectives.<\/p>\n

Frequently asked questions<\/h2>\n
\n

Do we need a separate device for shape and for pressure?<\/h3>\n

Not necessarily. Our systems capture plantar pressure together with camera-based posture and alignment views, which covers the brief most insole builds need. A separate shape device is useful where a clinic wants a physical mould as well, but it is not a requirement for a specified insole.<\/p>\n

How many walking passes should we record?<\/h3>\n

Enough to see a pattern rather than a single event, and enough that a bad pass can be discarded without losing the recording. The written routine should set the number so that recordings taken on different days remain comparable.<\/p>\n

Can we scan a patient in shoes?<\/h3>\n

The foot capture is taken barefoot, with the sock the patient normally wears. The shoe is recorded separately: internal length, removable liner or not, heel counter condition and outsole wear. Both records belong in the same file.<\/p>\n

What happens if a recording turns out to be unusable after the patient leaves?<\/h3>\n

The brief should not be written from it. Contact the patient and repeat the capture. Building from a recording you already distrust is how a re-make becomes a complaint, and the cost of a second appointment is smaller than the cost of a pair that has to be replaced.<\/p>\n

How is patient data handled?<\/h3>\n

Recordings stay in the clinic’s own system and are shared with the factory only as part of a production brief, with the patient’s knowledge. Clinics should apply their own local data protection rules; our role is to make export and deletion straightforward.<\/p>\n

Do your systems require an internet connection?<\/h3>\n

Capture works on site without one. Units connected to the internet can receive over-the-air updates, and remote assistance is available where the site allows it. Where connectivity is unreliable, support runs through the dedicated WhatsApp group and direct engineer contact.<\/p>\n

What training comes with the system?<\/h3>\n

Installation training covers the capture routine, the naming convention and the brief. Every system also ships with a dedicated WhatsApp group and direct access to our engineers, because the questions that matter usually appear in week three rather than on day one.<\/p>\n<\/div>\n

What we would do next<\/h2>\n

Write the routine before you compare equipment. One page, eight steps, posted in the room, is worth more than an extra feature on a specification sheet. Our F2 and FMP platform<\/a> is built around that sequence \u2014 static and dynamic pressure with posture capture in one session \u2014 and the core technology page<\/a> explains how the capture works.<\/p>\n

If the brief is going to a factory, our article on how a production order moves from data to dispatch<\/a> shows what happens at the other end. For terms, see the FAQ page<\/a>; to discuss a workflow, contact the team<\/a>.<\/p>\n
