Comparison guide

Choosing a gait analysis tool: the honest comparison

Four very different things get called a "gait analysis tool": motion-capture labs, pressure and force plates, consumer wearables, and in-shoe clinical platforms. They answer different questions at very different costs. Here is what each one actually measures, what it demands from you and your patient, and when each is the right choice.

Optical motion capture reconstructs movement in three dimensions. Setup and outputs depend on the camera system, model and protocol.
Pressure systems and force plates are different. Pressure systems map plantar pressure; force plates measure ground-reaction forces and moments.
Consumer wearables often focus on activity and wellness. Capabilities, validation and intended uses vary by device and feature.
Baliston Health uses the insole equipped with AI Mov-Scan to capture motion. The platform analyzes it and generates the Full Clinical Report.

Comparison	Motion-capture lab	Pressure systems / force plates	Consumer wearables	Baliston Health (in-shoe platform)
What it measures	3D motion; force measurement requires additional equipment	Pressure distribution, or ground-reaction forces and moments, depending on the device	Activity and other device-specific signals or estimates	Motion capture with 30+ platform-generated parameters, depending on the analysis; not plantar pressure

Motion-capture labs: three-dimensional movement

Optical systems reconstruct movement using cameras. Marker-based and markerless approaches have different setup requirements; the available outputs depend on the system and model. Motion capture can be combined with force plates, but camera-based movement tracking alone is not a direct force measurement. For a practice evaluating this approach, the relevant questions are capture space, staff training, setup time and the measurements the clinical question requires. Vicon's life-sciences overview describes optical and inertial approaches.

Pressure systems and force plates: different measurements

A plantar-pressure system shows how pressure is distributed across its sensing surface. A force plate measures ground-reaction forces and moments. Some systems also provide timing or other gait outputs, so it is misleading to describe every plate as a static snapshot. Check the specific device and protocol. See novel's emed pressure systems and AMTI's force-measurement systems for manufacturer descriptions.

For podiatry, the distinction matters when reviewing footwear, offloading or orthotic questions: motion data does not replace a pressure map. Our guide to motion sensors versus plantar-pressure measurement explains how these methods can complement one another.

Consumer wearables: check the specific feature

Watches, rings and activity sensors can provide useful context about daily movement. Their capabilities and intended uses differ. A step count, a running metric and a regulated medical feature should not be treated as equivalent just because each comes from a wearable. Evaluate the evidence and intended use for the particular output you plan to use.

Baliston Health: movement assessment inside the consultation

The insole equipped with AI Mov-Scan captures motion in the patient's own footwear. The platform analyzes the data and generates the Full Clinical Report. In three minutes, you have the report. Balia, the conversational AI assistant, explains the findings in plain language; the practitioner interprets, validates and decides.

Walk, Run, Jump and Neuro provide analysis-dependent outputs, with 30+ parameters per assessment depending on the analysis. These are not plantar-pressure maps, and repeating an assessment does not remove the need to consider changes in footwear, protocol or patient context. Explore the technology and workflow or see how this fits a podiatry consultation.

How to choose a gait analysis tool

Start from the question, not the device. Identify the measurement you need, the evidence supporting it, the assessment protocol and who will interpret the result. Then consider space, staff training, repeat assessments, reporting and data governance. Different methods can be used together; no single category answers every clinical question.

Frequently asked questions

Which gait analysis tool is best for a clinical practice?

Start with the clinical question. Optical motion capture assesses movement in three dimensions; pressure systems map plantar pressure; force plates measure ground-reaction forces and moments. Baliston Health uses in-shoe motion capture to support movement assessment, reporting and follow-up. These methods can complement one another; choose the system and protocol that measure what you need.

How is Baliston Health different from a motion-capture gait lab?

Optical gait labs use cameras to reconstruct movement, with setup and outputs depending on the system. Baliston Health uses the insole equipped with AI Mov-Scan to capture motion for platform analysis. In three minutes, you have the Full Clinical Report. The methods are not interchangeable for every measurement.

How is it different from a pressure plate or force plate?

A pressure system maps pressure distribution across its sensing surface. A force plate measures ground-reaction forces and moments. AI Mov-Scan captures motion, not plantar pressure. Its platform-generated movement parameters do not constitute a pressure map or a direct force-plate measurement. The appropriate method depends on the question being assessed.

How is it different from a consumer wearable or step counter?

Many consumer wearables focus on daily activity, although capabilities and intended uses vary by device and feature. Baliston Health is designed for practitioner-led movement assessment, with a clinical intelligence layer designed for practitioners. Check the intended use and evidence for the specific feature, rather than relying on the wearable category alone.

How accurate is in-shoe gait analysis compared to a lab?

Accuracy must be evaluated for the particular device, parameter, population and protocol. Agreement for one walking or running parameter does not establish accuracy for every analysis, diagnosis or patient group. Ask for the relevant validation evidence and its limitations before choosing a system; dataset size and practitioner adoption are not substitutes for that evidence.
