Postural support muscle injury

Because the rating levels are defined by the criteria in § 4.56, evidence that maps directly to those criteria carries the most weight. Medical records showing the nature and extent of the muscle injury itself — such as imaging, operative reports, or physician findings — help establish the baseline. Physical examination findings that describe muscle strength, range of motion, tenderness, guarding, or spasm help show how the injury affects function.

For higher rating levels, records documenting constant pain, muscle atrophy, or significantly limited movement of the spine support a more severe rating. For the lumbar region in particular, findings that affect your ability to stand, walk, or bear weight are relevant. Statements from you or people who know you describing how the condition affects your ability to work, carry out physical tasks, or perform daily activities can also reflect the functional impact. Records from treating providers, physical therapists, or VA examiners that describe ongoing symptoms and functional loss over time help show the severity and continuity of the condition.
