Tibial nerve paralysis

Medical records and examination findings that document what your foot, toes, and sole muscles can and cannot do are central to this rating. For a 40% rating, records showing absent plantar flexion, inability to adduct the foot, abolished toe flexion and separation, and no movement of the sole muscles would reflect the complete-paralysis criteria. Nerve conduction studies or electromyography that confirm the severity and location of the nerve lesion — particularly whether it is high in the back of the knee — can support that level as well.

For incomplete paralysis at the severe, moderate, or mild levels, examination findings showing reduced but not fully absent function are relevant. If your symptoms are only sensory — such as numbness or pain without motor loss — the regulation limits the rating to mild or at most moderate, so records distinguishing sensory-only involvement from motor involvement matter. Statements from you or people who know you describing how limited foot and toe function affects walking, balance, standing, or daily tasks can help show the practical degree of impairment.
