Sensory modalityTesting strategyUnit/scale

Clinical evaluation (Delayed wound healing, redness, swelling, pus, seroma, hypertrophic scarring, allergy, and foreign body sensation)
(1) Nociception Visual Analog Scale (VAS) used for pain estimation Value: 0–10
(2) Loss of sensation (hypesthesia) Measurement and photo documentation of the area on the lateral aspect of the foot with loss of sensationValue: cm2
Sharp-blunt discriminationValue: yes/no
(3) Tinel’s sign Palpation revealing Tinel’s sign and documentation of location in relation to the landmarksValue: relationship to landmarks in cm
(4) Spatial resolutionStatic and moving/dynamic two-point discrimination Value: s/m 2-PD in mm
(5) Pressure Semmes-Weinstein monofilament test Value: monofilament strength in g
(6) ThermoceptionCold-warm discriminationValue: yes/no
(7) Vibration 128 Hz tuning fork Value: scale from 0–8
