Area of Science:

  • Biomechanics
  • Orthopedic Surgery
  • Rehabilitation Engineering

Background:

  • Achilles tendon ruptures cause significant functional deficits in many patients.
  • Progressive loading accelerates healing but optimal loading profiles remain undefined.
  • Current rehabilitation lacks objective, longitudinal biomechanical data.

Purpose of the Study:

  • To develop and validate an instrumented immobilizing boot for quantifying Achilles tendon loading.
  • To enable personalized rehabilitation protocols by measuring patient biomechanics.
  • To assess the impact of foot positioning on Achilles tendon load during ambulation.

Main Methods:

  • Developed a 3-part instrumented insole and integrated load cell within an immobilizing boot.
  • Collected gait data from five healthy adults to validate the system.
  • Calibrated the insole for accurate Achilles tendon load measurement with the boot.
  • Assessed loading at 0 and 30 degrees of plantar flexion.

Main Results:

  • The instrumented boot accurately quantified Achilles tendon loading during ambulation.
  • Walking with the foot in 30 degrees plantar flexion reduced Achilles tendon loading by 60% (P < 0.001).
  • The system uses commercial sensors and a microcontroller for continuous, out-of-clinic monitoring.

Conclusions:

  • The instrumented immobilizing boot paradigm is a valid tool for assessing Achilles tendon loading.
  • Plantar flexion positioning effectively reduces mechanical stress on the Achilles tendon.
  • This technology facilitates personalized, data-driven rehabilitation for Achilles tendon injuries.
