Conditions

Ulcer, Diabetic foot, Microcirculation, Wond, Diabetische voet, Microcirculatie

Interventions

Non-invasive blood pressure measurements will be performed and a total of four LSCI will be made. During the LSCI two occlusion tests will be performed to measure the microcirculation of the foot and

Eligibility

Inclusion criteria

Inclusion criteria: • Diagnosed with a diabetic foot ulcer • Patients with diabetes mellitus, type I or type II • Aged 18 years or more • Presence of the hallux or second toe on both the left and the right foot for toe-pressure measurements

Exclusion criteria

Exclusion criteria: • Presence of an ulcer on both feet • Diagnosed with an infected foot ulcer

Design outcomes

Primary

Measure	Time frame
The main study parameters will be perfusion images of the diabetic foot with LSCI. The stability and intra- and inter- reproducibility of the LSCI technique will be measured and compared with non-invasive blood pressure measurements.	—

Secondary

Measure	Time frame
Secondary Objectives: (1) To investigate the relation of LSCI and currently used non-invasive blood pressure measurements (2) To investigate the differences in microcirculation between the three groups of patients (3) To investigate the stability of LSCI relating to (motion) artefacts or reproducibility of occlusion tests.	—
