A new device accurately measures prosthetic socket/shank alignment in the sagittal plane. This tool enhances prosthetic fitting, education, and research with 1-degree repeatability.

Area of Science:

  • Biomedical Engineering
  • Prosthetics and Orthotics

Background:

  • Accurate alignment of prosthetic sockets and shanks is crucial for patient mobility and comfort.
  • Existing methods for measuring angular alignment may lack precision or comprehensive range.

Purpose of the Study:

  • To describe a novel device for measuring socket/shank angular alignment in prostheses.
  • To evaluate the device's accuracy and repeatability across its measurement range.

Main Methods:

  • Development of a measurement device for prostheses with a Berkeley Adjustable Leg.
  • Assessment of angular alignment measurement in the sagittal plane.
  • Evaluation of measurement repeatability over a 20-degree range.

Main Results:
