Movement analysis apps for clinicians: a 2026 buyer's guide

The main types of objective movement analysis tools — smartphone video, 3D camera systems, sensors and lab capture — what to ask vendors, and the options in each category, described from each vendor's own website.

Key points

  • Five tool types. Smartphone/tablet markerless video apps, dedicated 3D markerless camera systems, wearable or connected sensors (IMUs, force plates, dynamometers), manual video-review apps, and laboratory marker-based motion capture.
  • Start from the tests you run. Pick the tool that captures your actual assessments — gait speed, Timed Up & Go, sit-to-stand, balance, range of motion — not the longest feature list.
  • Ask for measure-specific validation. Evidence for markerless video is strongest for spatiotemporal gait measures; joint angles need more caution. Ask what each product was compared against.
  • Hardware and workflow decide adoption. A tool that runs on devices you already own, and writes results into documentation, is more likely to be used at every visit.
  • Check the commercial fit. Home/remote capture for RTM, a Business Associate Agreement, and whether pricing scales per clinician, per patient or per device.

The five types of movement analysis tools

Smartphone & tablet markerless video

Computer vision estimates body landmarks from ordinary video, so there is nothing to attach to the patient. Low setup cost and portable to the bedside or home; accuracy depends on camera placement and standardized capture. See what markerless motion capture is.

Dedicated 3D markerless systems

Purpose-built camera rigs, tablets on tripods or portable kits that capture in three dimensions in a set space. Typically richer joint-level data in exchange for dedicated equipment and floor space.

Wearable & connected sensors

Inertial sensors (IMUs), force plates, dynamometers and connected goniometers measure motion, force or strength directly. Excellent for kinetics and continuous data; they must be placed, charged and synced. See smartphone vs. wearables.

Video review & lab motion capture

At one end, apps for slow-motion and frame-by-frame review where the clinician does the analysis by eye. At the other, laboratory marker-based capture — the research reference standard, but rarely practical for routine visits.

How to evaluate

Seven questions to ask every vendor

  1. What was it validated against, and for which measures? A study showing good agreement for gait speed does not establish accuracy for joint angles or tremor. Ask for peer-reviewed comparisons with a laboratory reference for the measures you will document. Our evidence & validation page summarizes the published research on markerless, video-based analysis.
  2. Which standard clinical tests does it support? Match the tool to the assessments you already run and report. Our guide to movement assessment tests explains how each is run and read.
  3. What hardware and space does it need? A phone or tablet you own, a dedicated camera system and room, or sensors that must be worn, charged and synced — this largely decides whether measurement happens at every visit.
  4. How do results reach documentation? Ask about report formats, EMR/EHR integration or export, and how a reviewer would see a trend across visits.
  5. Can patients capture at home? Remote Therapeutic Monitoring requires data collected between visits. Check whether the tool supports home capture and the data-day and time rules in our RTM CPT code reference.
  6. How is patient data protected? Ask whether the vendor will sign a Business Associate Agreement and how video and movement data are stored, encrypted and access-controlled.
  7. How does pricing scale? Per clinician, per patient, per device or per site changes the cost of growing a caseload. Ask for the full price, including hardware and onboarding.

Where Kinetically fits. Kinetically is a smartphone and tablet markerless app built around the standardized tests clinicians already run — Timed Up & Go, gait speed, sit-to-stand, postural sway, range of motion, tremor and bradykinesia — captured the same way at every visit and at home, with results that flow into documentation. It is priced per clinician (see pricing), is HIPAA-aligned by design with a BAA available (security & compliance), and supports rather than replaces clinical judgment. If you need force or strength data, a sensor or force-plate tool measures what a camera cannot; if you need research-grade kinetics, a laboratory remains the reference.

FAQ

Quick answers

What types of movement analysis tools are available to clinicians?

Five broad types: smartphone or tablet apps that analyze ordinary video without markers; dedicated 3D markerless camera systems set up in a clinic or capture space; wearable or connected sensors such as inertial sensors, force plates and dynamometers; manual video-review apps where the clinician annotates footage; and laboratory marker-based motion capture, the research reference standard.

Can a smartphone app measure gait accurately enough for clinical use?

Peer-reviewed studies show that markerless, video-based analysis generally agrees well with laboratory systems for spatiotemporal gait measures such as speed and step length, while some joint-angle measures call for more caution. Accuracy depends on the measure, camera placement and how standardized the capture is, so ask each vendor for validation of the specific measures you plan to use.

What should I ask a movement analysis vendor before buying?

Ask what the tool was validated against and for which measures, which standard clinical tests it supports, what hardware and space it needs, how results reach your documentation or EMR, whether it supports remote or home capture for RTM workflows, whether it will sign a Business Associate Agreement, and whether pricing is per clinician, per patient or per device.

Do I need special hardware for markerless motion capture?

It depends on the product. Some tools run on a phone or tablet you already own; others are dedicated systems with their own cameras, computer or capture space. Sensor-based tools need the sensors themselves, and laboratory systems need multiple calibrated cameras and reflective markers.

How does this guide handle regulatory and validation claims?

It notes a regulatory status only where a vendor states one on its own website, with a link. It makes no regulatory claim for Kinetically: Kinetically provides objective movement metrics intended to support, not replace, clinical judgment. The research behind smartphone movement analysis is summarized on our evidence page.

How is Kinetically priced?

Kinetically offers a 15-day free trial of the full product, a Professional plan at $29 per clinician per month or $249 per clinician per year, and a custom Enterprise plan. It is billed per clinician, not per patient.
