Figure 3. Mean (SEM) bump detection thresholds for all healthy subjects (Control) and all patients (All) with neuropathy. Patients were subdivided according to those with sensory symptoms in the feet only (Feet) and those in whom symptoms were also reported in the hands (Hands). *** Significant difference from control; ### significant difference from feet. (p=0.001)
