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

Recording the sole while someone walks is a different engineering
\nproblem from recording it while someone stands, and recording it while someone runs is a third
\nproblem again.<\/strong> Each step up in speed shortens the time available to capture, changes the
\nloading that arrives, and increases the sensitivity of the result to how the session was set up.
\nTeams that understand this before they buy end up with recordings they can compare across sessions
\nand across people. Teams that do not often end up with a set of images that look impressive and
\nanswer nothing in particular.<\/p>\n

FOOTWORK LAB builds dynamic gait platforms as part of our foot assessment range, manufactured at
\nour own plant in Ruichang, Jiangxi Province, where we have produced since 2018. The
\nF5-LAB dynamic gait system<\/a> is the platform in our range
\ndesigned for walking and running capture. Most of the conversations we have with buyers about it are
\nnot about sensors at all. They are about the room, the routine, and what the recording is for. This
\narticle covers those three, because they determine whether the platform earns its place.<\/p>\n

What walking and running ask of a recording system<\/h2>\n

The essential difference between walking and running is not intensity. It is the amount of time
\nthe foot spends in contact with the ground, and the fact that the two feet are never in the same
\nphase of the cycle.<\/p>\n

During walking, the contact phase is long and there is a period when both feet are on the ground
\nat once. During running, contact time shortens considerably and there is a flight phase in which
\nneither foot is loaded. The loading that arrives is also different in character, arriving faster and
\npeaking higher, and the sole of the foot meets the surface in a different way.<\/p>\n

For a recording system, these differences translate into three requirements. The capture has to
\nbe fast enough to resolve a shortened contact event. The capture area has to cover a stride rather
\nthan a stance. And the recording has to track both feet across a sequence, because a single foot
\nrecorded in isolation cannot describe how the two sides relate to each other.<\/p>\n

This is why a standing plate and a walking platform are not interchangeable products with
\ndifferent prices. They are built to answer different questions, and the platform exists because
\nmovement is where much of the informative loading occurs.<\/p>\n

Capture conditions: barefoot, in-shoe and on-platform<\/h2>\n

Before choosing a configuration, decide the conditions the room will use. This single decision
\nconstrains everything else, and it is far easier to make before purchase than to change afterwards.<\/p>\n

Barefoot capture<\/h3>\n

The foot meets the recording surface directly, which gives an unobstructed view of how load is
\ndistributed through the sole. It is the most common condition for assessment work, and the easiest
\nto keep consistent between sessions.<\/p>\n

In-shoe capture<\/h3>\n

Where the question concerns what happens inside footwear, the measurement has to be taken where
\nthe loading occurs. This condition tells you about the interaction between foot, insole and shoe,
\nwhich is a different question from barefoot loading and cannot be inferred from it.<\/p>\n

Platform capture during movement<\/h3>\n

A platform allows the person to move across the capture area at their natural pace. What matters
\nhere is that the run-up and run-out are long enough for the person to be moving naturally by the
\ntime they cross the recording area, and that the surface does not change underfoot.<\/p>\n

The practical rule we give buyers is to choose one condition per routine and keep it. Changing
\nconditions between sessions destroys comparability, and comparability is where most of the value
\nsits, because one recording in isolation says far less than the same recording repeated over time.<\/p>\n

What the platform records: pressure, timing and position<\/h2>\n

Three families of output come out of a dynamic recording, and each answers a different kind of
\nquestion.<\/p>\n
