C&P Range of Motion (ROM) & DeLuca Visualizer
Under binding federal precedent (*DeLuca v. Brown* and *Mitchell v. Shinseki*), functional loss due to pain must be rated at the point where pain begins. Use this visualizer to model your goniometer measurements against statutory percentage benchmarks.
C&P Range of Motion (ROM) & DeLuca Visualizer
Compare your maximum active movement against the angle where pain begins. Under federal law, functional loss caused by pain must be rated at the pain-stop point, not where forced movement terminates.
Interactive Goniometer Controls
Normal: 90°The angle reached when pushing through pain or when the examiner forces motion.
The legally required stopping point where pain, fatigue, or flare-up limitation first begins.

Mandatory Legal Precedent for Musculoskeletal Exams
1. DeLuca v. Brown (1995)
Federal court established that examiners cannot rate only mechanical restriction. When motion causes pain, the angle at which pain begins is the statutory limit of functional motion.
2. Mitchell v. Shinseki (2011)
Requires examiners to record or estimate additional loss of motion in degrees caused by repetitive use and during flare-ups. Failure to document flare-ups renders the exam legally inadequate.
3. 38 CFR § 4.59 (Painful Motion)
Joints with active, passive, or weight-bearing pain on movement are entitled to at least the minimum compensable rating (typically 10%), even if range of motion is completely normal.
