Brief Summary:
The prevalence of abnormal plantar pressure distribution (APD) and its connection with various factors among patients with diabetes is not known. The purpose of this study was to evaluate the prevalence of the APD and its connection with selected factors among patients with diabetes.

Condition or disease Intervention/treatment
Diabetes Complications Other: retrospective observational study with no intervention

Detailed Description:

The abnormal plantar pressure distribution (APD) plays a key role in the formation of plantar calluses which are responsible for diabetic foot ulcer.

The knowledge of APD is necessary to plan proper prevention in the group of patients with diabetes ( DM- diabetes mellitus).

Medical records from previous patients' visits of non-ulcer patients with diabetes were retrospectively analysed. The relationship between APD, obtained during a pedobarographic test as a semi-quantitative assessment with colourful print analysis, and neuropathy, gender, age and BMI was searched.

Group/Cohort Intervention/treatment
patients with diabetes
Data from medical records from : non-ulcer patients with DM (diabetes mellitus) from the Diabetic Foot Centre (DFC) in Wroclaw. As it is a retrospective analysis no intervention is planned.
Other: retrospective observational study with no intervention
no intervention

Primary Outcome Measures :
  1. abnormal plantar pressure distribution [ Time Frame: 15 months ]
    static pedobarographic test with semi-quantitative assessment

Secondary Outcome Measures :
  1. neuropathy [ Time Frame: 15 months ]
    Peripheral neuropathy is assessed with questions and clinical evaluation. A nurse asks the patient about stinging, numbness, tingling, or burning of the foot. Ten-gram monofilament and tuning fork (128 MHz) tests are administered. Monofilament is applied in 10 locations on the sole and one on the dorsal part of the foot for checking the loss of protective sensation. A positive monofilament test is considered to be the lack of sensation of tightness in at least 6 of 11 tested sites. The tuning fork is applied for vibration detection to both ankles, the first metatarsophalangeal joint, and the anterior aspect of the shin bone sites. A positive vibration test is considered to be no detection of vibration in three of four test sites.Two positive test results and typical symptoms of neuropathy are the basis for confirmation of symmetric, peripheral, sensory polyneuropathy. The condition required for the occurrence of these disorders was symmetry.

  2. BMI [ Time Frame: 15 months ]
