Diabetic Polyneuropathy: Examination

A comprehensive clinical examination is the basis for selecting further diagnostic steps:

  • General physical examination – including blood pressure, pulse, body weight, height; further:
    • Inspection (viewing).
      • Skin and mucous membranes (skin temperature, skin tugor and perspiration).
      • Gait
      • Acquisition of muscle and joint function
      • Foot [rhagades?, blistering?, subcutaneous hemorrhages?; hyperkeratosis (keratinization)?, signs of bacterial infection and/or mycosis (fungal disease)?, foot deformities, as evidence of diabetic neuroosteoarthropathy, foot ulcer (foot ulcers)?]
      • Shoes and insoles (tactile control).
    • Palpation of the peripheral pulses (palpation of the foot pulses of the tibial artery and the dorsalis pedis artery, on both sides).
    • Tuning fork test for diagnosis and progression of diseases associated with decreased vibration sensation (pallhypesthesia) and decreased depth sensitivity [diabetic polyneuropathy?].
    • Auscultation (listening) of the heart.
    • Auscultation of the lungs
    • Palpation (palpation) of the abdomen (abdomen) (tenderness?, knocking pain?, coughing pain?, defensive tension?, hernial orifices?, kidney bearing knocking pain?)
  • Neurological examination (examination always bilateral!).
    • Muscle reflexes (Achilles tendon reflex and patellar tendon reflex).
    • Motor function
    • Sensitivity measurement:
      • Touch sensation (e.g., with cotton swab).
      • Pressure and touch sensation with 10 g monofilament.
      • Cold-hot discrimination
      • Pain identification [findings in sensorimotor diabetic polyneuropathy: bilateral: limb-segment determination (e.g., sock-shaped)]
      • Temperature sensation (e.g., cold metal/vocal fork).
      • Vibration sensation with the 128 Hz tuning fork according to Rysel-Seiffer [early sign of diabetic polyneuropathy: decreased vibration sensation in the tuning fork test].
  • Health check
