K931128 is an FDA 510(k) clearance for the BASIC SHOULDER CPM. Classified as Exerciser, Powered (product code BXB), Class I - General Controls.

Submitted by Danninger Medical Technology, Inc. (Concord, US). The FDA issued a Cleared decision on May 6, 1994 after a review of 427 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Physical Medicine FDA review panel, regulated under 21 CFR 890.5380 - 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.
