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 Parkinson’s disease (PD). “PD all patients” refers to mean values from the whole group (all patients with PD), “PD no PN” refers to mean values from PD patients without large fiber neuropathy, “PD SFN” refers to patients with PD and small fiber neuropathy and “PD Neuropathy” to mean values in patients with PD and large-fiber neuropathy. Part b shows mean values of peroneal motor and sural sensory conduction velocities in the same groups
