Summary
Background:
Modern optoelectronic methods are used in various sectors to precisely measure surface areas of objects. Building on previous experiences, the BS04 optoelectronic scanner has been constructed for contactless measurements of the human body surface area.
Objective:
The main objective of the study was to verify the feasibility and suitability of the BS04 for use in healthcare and to compare differences in the measurement of the antropometric dimensions of the lower limbs extremities the optoelectronic method and the manual measurement.
Methods:
First, a pilot study was carried out to verify the procedure of measurement of the lower extremities dimensions using BS04. Then, a total of 72 series of repeated automated and 144 series of repeated manual measurements were performed in 24 volunteers at 14 measurement points located on the lower extremities. A pairwise t-test for difference values was used to compare the results. Statistical significance was assessed at 5% level.
Results:
The comparison showed statistically significant differences in all cases. The mean difference between ranges from –3.20 to –0.47 cm (min. –6.58 cm, max. 0.78 cm). On average, the values obtained by BS04 were higher than by manual measurements. Certain limitations were found that, for the time being, prevent full use of the BS04 in the entire population, particularly immobile individuals.
Conclusions:
A huge prospect of using this device lies in the prevention and early detection of onset swelling of various causes, also in differential diagnosis and treatment of lower limb swelling due to venous insufficiency, lymphatic disorders of the lower limb vascular vessels or disorders of fat metabolism. Last but not least, this device is potentially of great importance in the design of orthopedic, compressible and other therapeutic medical devices. From this point of view, the exact values measured by the BS04 would allow the construction of medical aids with adequate mild compression even for diabetic patients.
