K171547 is an FDA 510(k) clearance for the Qualisys Clinical System. Classified as Interactive Rehabilitation Exercise Devices (product code LXJ), Class II - Special Controls.

Submitted by Qualisys AB (Goteborg, SE). The FDA issued a Cleared decision on August 2, 2018 after a review of 433 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Physical Medicine FDA review panel, regulated under 21 CFR 890.5360 - the FDA physical medicine device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Physical Medicine submissions.
