A high stepping gate implies distal more than proximal weakness. Hammer toes are a finding in Charcot-Marie-Tooth (hereditary motor and sensory) neuropathies, most of which also feature demyelination of peripheral myelin sheaths. Slowing of nerve conduction velocities could have demonstrated the same thing less invasively.?
