==Overview==
[[Patients]] with [[diabetic foot]] [[ulcer]] could appear ill if [[ulcers]] are severe or [[infection|infected]]. In severe and [[Chronic (medical)|chronic]] [[infection|infected]] [[ulcers]] [[patients]] may have [[fever]], [[tachycardia]] and low [[blood pressure]]. [[Neuromuscular junction|Neuromuscular]] [[physical examination|examination]] of [[patients]] with [[diabetic foot]] is usually normal, except in their [[foot]]. Altered motor tone, [[Neurological examination|reflexes]] and sensation is expected in these [[patients]]. [[Neuropathy]] [[symptoms]] score (NSS) and [[neuropathy]] disability score (NDS) are helpful in neuropathy assessment of [[patients]] with [[diabetic foot]]. Findings such as impaired [[vibration]] and [[pressure]] perception, [[Proprioception|position sense]] and thresholds for warm thermal perception favor the [[diagnosis]] of [[neuropathy|sensory neuropathy]]. It is critical to check the [[Limb (anatomy)|extremities]] for findings such as [[ulcers]], peeling [[skin]], dilated or [[varicose veins]], shiny [[skin]] with reduced [[hair]] distribution and broken [[nail]] while examining [[diabetic foot]]. Moreover [[infection]] possibility should be evaluated. Findings such as [[pus]], [[erythema]], Warmth, [[induration]] and bad [[odor]] suggest the presence of [[infection]]. In some cases unroofing a small [[scar]] demonstrates a deeper [[infection|infected]] [[abscesses]]. In the other word, evaluating an [[ulcer]] for [[infection]] must be done after debridement. Other necessary [[physical examinations]] in these [[patients]] are checking the [[capillary]] filling time, [[Peripheral arterial disease screening|ankle brachial index]], tactile and vibration [[sensation]] and [[pressure]] perception.

* "The [[PAD]] screening score using the hand-held Doppler has the greatest diagnostic accuracy"
** The Score is:
***The number of auscultated components (right posterior tibial artery + left posterior tibial artery; range of 0 for none heard to 3 for normal for each artery)<br/>plus
***The grade of palpated posterior tibial artery (right posterior tibial artery + left posterior tibial artery; 2 for normal, 1 for palpated but abnormal, 0 for not palpable for each artery)<br/>plus
***A history of myocardial infarction (1 for none, 0 for prior myocardial infarction)

*Temperature
*Increased temperature could be due to [[deep vein thrombosis]] while decreased temperature could be an [[ischemia]] presentation.

*[[Tenderness]] (squeeze [[Tibia|calf]] [[muscle]] and [[achilles tendon]] for [[tenderness]])

*[[Muscle strength]] and tone
*Check [[Peripheral arterial disease screening|ankle brachial index]] ([[Peripheral arterial disease screening|ABI]])
*Pinprick discrimination and tactile [[sensation]] test (use a cotton wool to examine)
*Vibration test (use a 128 Hz-tuning fork)
*Pressure perception test (use a 10-gram (5.07) Semmes––Weinstein monofilament)
**Single most practical method to assess risks for [[diabetic foot]] such as [[neuropathy]]
*Quantitative sensory testing and autonomic testing
*Probing
**Using a blunted sterile probe will help [[physicians]] to determine [[ulcer]]'s margins, sinus tract development and involvement of [[tendons]], [[bone|bones]] or [[joints]].
**Positive probe-to-[[bone]] is strongly correlated with [[osteomyelitis]].

The working group separately describes the UT classification of ulcers. This system includes "preulcerative" lesions:
* "Grade 0 wounds are preulcerative areas or previous ulcer sites that are now completely epithelialized after debridement of hyperkeratosis and nonviable tissue. The diagnosis of a Grade 0 wound can be made only after removal of any regional hyperkeratosis, as quite often frank ulcerations may be hidden by overlying calluses"
* The system adds whether the lesion is associated with infection or ischemia.

Overview

Patients with diabetic foot ulcer could appear ill if ulcers are severe or infected. In severe and chronic infected ulcers patients may have fever, tachycardia and low blood pressure. Neuromuscular examination of patients with diabetic foot is usually normal, except in their foot. Altered motor tone, reflexes and sensation is expected in these patients. Neuropathy symptoms score (NSS) and neuropathy disability score (NDS) are helpful in neuropathy assessment of patients with diabetic foot. Findings such as impaired vibration and pressure perception, position sense and thresholds for warm thermal perception favor the diagnosis of sensory neuropathy. It is critical to check the extremities for findings such as ulcers, peeling skin, dilated or varicose veins, shiny skin with reduced hair distribution and broken nail while examining diabetic foot. Moreover infection possibility should be evaluated. Findings such as pus, erythema, Warmth, induration and bad odor suggest the presence of infection. In some cases unroofing a small scar demonstrates a deeper infected abscesses. In the other word, evaluating an ulcer for infection must be done after debridement. Other necessary physical examinations in these patients are checking the capillary filling time, ankle brachial index, tactile and vibration sensation and pressure perception.

Neuropathy Assessment

The Ipswich Touch Test (IpTT) can diagnosis neuropathy[1][2]. The A clinical practice guideline by the International Working Group on the Diabetic Foot (IWGDF) recommended the (IpTT) as an alternative to the monofilament exam[3] Instructions for the IpTT are:

"lightly touch the tips of the first, third and fifth toes of each foot, for 1–2 s, with the tip of the index finger. They were not to push, prod, tap or poke, because this may elicit a sensation other than light touch. With their eyes closed, the patient was instructed to say yes whenever they felt the touch."[4]

The neuropathy symptoms score (NSS) and neuropathy disability score (NDS) are helpful in physical examination of patients with diabetic foot.[5][6][7]. Findings that favor the diagnosis of sensory neuropathy:[8][9]

Vascular

The Rational Clinical Examination group concluded[10]"

  • "The PAD screening score using the hand-held Doppler has the greatest diagnostic accuracy"
    • The Score is:
      • The number of auscultated components (right posterior tibial artery + left posterior tibial artery; range of 0 for none heard to 3 for normal for each artery)
        plus
      • The grade of palpated posterior tibial artery (right posterior tibial artery + left posterior tibial artery; 2 for normal, 1 for palpated but abnormal, 0 for not palpable for each artery)
        plus
      • A history of myocardial infarction (1 for none, 0 for prior myocardial infarction)
    • Interpretation: normal is 10 (combining both feet). A score < 6 increases risk of PAD.


The USPSTF stated[11]:

  • "The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for PAD and CVD risk with the ABI in asymptomatic adults. (I statement)."

Staging of diabetic wounds

A systematic review identified better staging systems[18]:

  • University of Texas (UT) Score[19]

More recently, the International Working Group’s diabetic foot (IWGDF) risk classification [20].

International Working Group’s diabetic foot (IWGDF) risk classification [20]
Risk group Findings
Risk Group 0 No neuropathy
No peripheral arterial
No foot deformity or limited joint mobility
Risk Group 1 Peripheral neuropathy
No peripheral arterial
No foot deformity or limited joint mobility
Risk Group 2 Peripheral neuropathy and foot deformity or limited joint mobility
and/or peripheral arterial disease
Risk Group 3 History of ulcer or amputation or Charcot

The working group separately describes the UT classification of ulcers. This system includes "preulcerative" lesions:

  • "Grade 0 wounds are preulcerative areas or previous ulcer sites that are now completely epithelialized after debridement of hyperkeratosis and nonviable tissue. The diagnosis of a Grade 0 wound can be made only after removal of any regional hyperkeratosis, as quite often frank ulcerations may be hidden by overlying calluses"
  • The system adds whether the lesion is associated with infection or ischemia.
