AI Article Synopsis
- Researchers aimed to improve estimates of a perpetrator's foot size based on bare footprints found at crime scenes.
- The study analyzed data from 146 white British university students, examining the relationship between footprint length and actual foot length.
- Results indicated that sex did not significantly influence foot length; instead, a regression equation was derived: foot length = 19.89 + 0.95 × footprint length ± 8 mm.
Article Abstract
In forensic intelligence-gathering it would be useful to be able to estimate the size of a perpetrator's foot from a standing bare footprint found at the scene of crime. Currently, the advice is to add a fixed amount to the length of the footprint (typically 1.5 or 2.0 cm), but there is little evidence for this approach. This study used measured footprint and actual foot lengths from 146 participants from the white British student population of a University in the UK. Data were analysed using multiple regression with foot length as the dependent (outcome) variable and footprint length and sex as the independent variable/factor respectively. Sex was not a significant predictor. The regression equation for the best estimate of the foot length is 19.89 + 0.95 × print length ± 8 mm.

Background: In 2011, the Veterans Health Administration (VHA) undertook multidisciplinary efforts to improve care for patients with nonhealing foot ulcers and reduce leg amputation rates. This article examines the impact of interdisciplinary care for amputation prevention in the VHA.
Methods: The VHA patient population was characterized using internal registries.

Background: Several foot models have been developed to estimate the behaviors of the plantar aponeurosis (PA) during movements. However, these models did not consider the actual path of the PA, and their validity remains insufficiently investigated due to the absence of direct PA measurement during movements.
Research Question: Would developing a foot model that considers the actual path of the PA improve the accuracy of estimating the PA behavior during movements?
Methods: The foot model was developed based on the CT scans of the six feet with 20 markers attached.

Following lower limb amputation residuum skin from the lower leg is used to reconstruct the residual limb. Unlike skin on the sole of the foot (plantar skin), leg skin is not inherently load bearing. Despite this, leg skin is required to be load bearing in the prosthetic socket.
