Part a shows mean peroneal compound motor action potential (CMAP, in mV) amplitudes and mean sural sensory nerve action potential (SNAP, in μV) amplitudes in patients with parkinsonism. “Parkinsonism all patients” refers to mean values from the whole group (all patients with parkinsonism), “Parkinsonism no PN” refers to mean values from parkinsonism patients without large fiber neuropathy, “Parkinsonism SFN” refers to patients with parkinsonism and small fiber neuropathy and “Parkinsonism Neuropathy” to mean values in patients with Parkinsonism and large-fiber neuropathy. Part b shows mean values of peroneal motor and sural sensory conduction velocities in the same groups
