Brief Summary:
This clinical study evaluates the reliability, concurrent validity, and clinical feasibility of a new method to determine leg volume, namely the Structure Sensor Scanner.
The volume of both legs will be determined using three different measurement methods:
1. A scanning method using a Structure Sensor Scanner: for this, both legs are scanned all around with an iPad with the Structure Sensor attached to the tablet. This is performed while standing. The sensor captures depth images, which are then converted into a three-dimensional image of both legs. A computer program is then used to determine the volume of both legs and specific segments of the legs.
2. The circumference measurement using a perimeter: the perimeter consists of a flexible metal strip with a tape measure attached every 4 cm, each ending in a small weight. The person must sit and place only the foot on a small bench so that the entire leg is free. The perimeter is then placed on the leg. Finally, the tape measures are wrapped around the leg, and the circumferences are read. The leg volume is then calculated using the formula of the truncated cone.
3. The optoelectronic volumetry using the Perometer®: for this, the person must stand in shoulder-width stance on the Perometer platform, with one leg inside the frame. The frame is then moved upward. The frame captures silhouettes from which circumference and volumes are calculated through elliptical approximation.
To investigate the reliability, the intra-class correlation coefficient (ICC) is calculated as well as the SEM, SRD and a two-tailed paired samples t-test or a wilcoxon signed rank test (in case of not-normally distributed data). To investigate the concurrent validity of the Structure Sensor Scanner, the results from the scanner method will be compared with those of the two other methods. Regarding the clinical feasibility the duration of each measurement is recorded and a purpose-designed feasibility questionnaire which is completed by the assessors is used.
