Paralysis of the posterior tibial nerve, which may cause foot and toe weakness and heel or sole numbness.
To support a higher rating, your records should reflect how closely your symptoms match the criteria for each level. For complete paralysis at 30%, medical records and physical exam findings documenting inability to flex the toes, weakened adduction, impaired plantar flexion, and causalgic pain in the sole of the foot would be relevant. Nerve conduction studies or electromyography showing complete loss of posterior tibial nerve function can help establish this level.
For incomplete paralysis, exam findings that document partial loss of motor or sensory function in the sole and toes are relevant. The degree of functional loss separates severe from moderate or mild. Your own statements, and statements from people who know you, describing how foot pain, weakness, or numbness affects walking, standing, working, or daily activities can help show the severity of incomplete paralysis. If your symptoms are purely sensory, the evidence would reflect that limitation in the rating level that applies.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
