Nociception at the diabetic foot, an uncharted territory

Figure 7 Lowered pain perception thresholds (hyperalgesia) after acute skeletal trauma of the foot in 13 healthy control subjects (sprain, toe fracture) and in 12 diabetic foot patients (elective surgery) at the injured site. Data are combined from ref. [59,61]. A: Cutaneous pressure pain perception threshold (mN) (pinprick) at plantar digital skinfold (medians); B: Deep pressure pain perception threshold (kPa) over metatarsophalangeal joint (medians); C: Deep pressure pain perception threshold (kPa) over musculus abductor hallucis (medians).
