Aims and objectives
The aim of this study is to investigate whether it is possible to differentiate between diabetic and healthy heel pads by means of real-time sonoelastography (ElaXto).
sonoelastography has not been not used for clinical investigations of the heel pad elasticity.
Eight diabetic (4M-4F,
55-80 years) and 8 healthy subjects (5F-3M,
60-76 years) underwent B-Mode ultrasound (for heel pad thickness measurement) and sonoelastography (for soft tissue investigation) on both heel pads.
Methods and materials
Subjects Eight subjects affected with Type II diabetes (4M-4F,
55-80 years) and 8 controls (5F-3M,
60-76 years) were enrolled in this study.
The subjects’ characteristics are reported in Table 1.
Both feet of each subject were considered so that 32 heels were investigated.
All subjects declared to have never had injuries/trauma to any of the feet.
All participants were volunteers and were informed about the conditions of the test that involved no harmful procedures or physical pain. Before...
B-Mode ultrasound An example of heel pad scanned by US is shown in Figure 2,
where the yellow dashed line indicates the UHPT.
Table 2 shows UHPT values of both feet grouped by gender and expressed as mean ± one standard deviation. Table 2 Average heel pad thickness of right and left heels for controls and diabetic patients Controls Diabetic subjects UHPT (mm) right heel 16.9±4.1 15.7±2.1 UHPT (mm) left heel 16.9±4.1 16.0±2.1 Paired t-test showed no significant difference between right and...
The aim of this study was to investigate whether it is possible to differentiate between diabetic and healthy heel pads in terms of elasticity by means of ElaXto sonoelstography. To date,
sonoelastography has not been used for clinical correlation of heel pad elasticity.
Over the past decades,
ultrasound technology has been one of the most popular techniques for the evaluation of the morphology and properties tissues ,
but reported controversial results in diabetic patients.
