SCANLOAD: The Effect of Limb Loading on Lower Limb Geometry

NCT04600102 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2022-07-11

No results posted yet for this study

Summary

Orthotists currently use a range of weight bearing conditions when casting or scanning a patient's limb during the Ankle foot orthosis (AFO) fitting process. This variability in clinical practice is the result of differing opinions regarding the best method for fitting, and a limited understanding of how weight bearing affects the resulting geometry. Few studies have been performed to determine the effect of weight bearing on resulting geometry, or the consistency of the geometry obtained. In this study we seek to evaluate the effect of foot loading on lower limb geometry and the consistency of measurements using low-cost 3D scanning technology, with implications for fitting AFOs.

Conditions

  • Foot Injuries and Disorders

Interventions

DEVICE

Structure Sensor

A 3D representation of each participant's lower limb geometry will be obtained using a Structure Sensor scanner (Occipital, Inc.) which uses an infrared structured light projector to construct a 3D image of an object. The scanner is connected to an iPad; to operate the user rotates the iPad camera around the desired object. In seconds, the entire geometry is digitally reconstructed.
