The Wheelchair Aerobic Fitness Trainer (WAFT) is an improved wheelchair ergometer for assessing aerobic fitness and diagnosing heart disease in individuals with lower limb disabilities. Its technology transfer signifies advancements in rehabilitation and diagnostic applications.

Area of Science:

  • Rehabilitation Engineering
  • Cardiovascular Diagnostics
  • Assistive Technology

Background:

  • Manual wheelchair users with lower limb disabilities often face challenges in traditional aerobic capacity and cardiovascular diagnostic testing.
  • Existing methods like treadmill or cycle ergometry may be inadequate or inaccessible for this population.
  • The Wheelchair Aerobic Fitness Trainer (WAFT) was developed to address these limitations.

Purpose of the Study:

  • To describe the evolution and technological advancements of the WAFT.
  • To highlight its utility in determining aerobic capacity and diagnosing coronary artery disease.
  • To detail its transition into the technology transfer process for wider application.

Main Methods:

  • The WAFT, a wheelchair ergometer, was developed and refined through research studies.
