|Ambulatory Aids for
People with Mobility Impairments
The market for disabled-person aids has great potential for
improvement. This project is to improve design, materials and manufacturing processes for
aids such as a forearm crutch. Between 1993 and 2000, the crutch market is projected to
experience a compound annual growth of 5.2% and by 2000, 3.8 million pairs of crutches
will be sold per year.
The Air Force Research Laboratory Materials and Manufacturing
Directorate (AFRL/ML) scientists will assist in the design and development of
disabled-person aids such as crutches, walkers and canes. This improved equipment will be
ergonomically engineered, aesthetically pleasing, and made of strong but lightweight,
advanced fiber-matrix composite materials.
- Both military and civilian
disabled persons will benefit from the improved disabled-person aids being developed under
the Cooperative Research and Development Agreement (CRADA).
- Military biomedical research will also benefit from the data generated under
- The main attributes of these new disabled-person aids
- Low weight and durability of carbon
- Cost effective because it will last much longer
- Ergonomically designed which provides more comfort and less stress to the user.
If you have any questions about this Cooperative Research and Development
Agreement or are interested in getting more information about technology
transfer and CRADA projects, please contact Jim Singer at Wright
Technology Network (937) 253-0217 or CRADA@wtn.org
- The original CRADA was for the
development of a superior forearm crutch.
- This CRADA between Ergonomics, Inc. and the
has been extended and expanded to include the production of prototypes.
- The extended CRADA will cover the final development phase of the forearm crutch
and will be extended to development of other ambulatory aids such as canes and walkers.
- Building on the technology identified in developing the forearm crutch, these
devices will be designed with the goal of providing users with a more ergonomically
correct product than those presently available.
