We have many different services available to meet your needs. Beneficial Designs provides highly efficient assessment and transition plan services to identify hazards and access issues in the sidewalk and outdoor recreation environments.

Wheelchair Testing

We can insure that your manual and powered wheelchair products will be tested to meet the requirements necessary for Pricing, Data Analysis and Coding (PDAC), 510k submission to the Food and Drug Administration (FDA), and/or United States Department of Veterans Affairs (VA) submission.

Sidewalk Assessment

Sidewalk assessment services are available; our sidewalk assessors are assessing college campuses and cities all across the country using the Public Rights-of-Way Assessment Process—PROWAP—electronics and software. Call today to see how our services can help you identify tripping and ADA liabilities.

Outdoor Recreation Assessment Equipment

Our trail assessment products and software have been developed to enable you to locate liabilities and access issues. We are constantly developing the right tools to efficiently assess all outdoor environments for the safety and enjoyment of people of all abilities.

Surface Measurement Tools

The Rotational Penetrometer is a precision instrumented surface indenter for measuring the firmness and stability of ground and floor surfaces, such as trails, playgrounds, and carpets. The Rotational Penetrometer is the only device of its kind—a reliable, objective, portable instrument for testing surface firmness and stability.

Mapping and Signage

The Architectural Barriers Act—ABA—requires that trail signage contain Trail Access Information, which is created from data collected during trail assessments using the Universal Trail Assessment Process (UTAP) and the High Efficiency Trail Assessment Process (HETAP). All trail users find grade, cross slope, tread width, surface, and obstruction information useful for the enjoyment of trails.

Trail Training

Onsite training is available to become a certified Trail Assessment Coordinator using the Universal Trail Assessment Process (UTAP) and to become proficient in the use of the High Efficiency Trail Assessment Process (HETAP) hardware and software.

Pax Press Publications

Published books include The Manual Wheelchair Training Guide, The Powered Wheelchair Training Guide, and A Guide to Wheelchair Selection. These guides provide new and experienced users and rehabilitation professionals with valuable reference materials.

Research and Development

We are working on new technologies that will make your access issues disappear. We are currently developing an application for mobile devices that will enable the efficient assessment of all outdoor recreation environments, including picnic and camping areas, outdoor recreation trails, and access routes.

Expert Witness Services

Peter Axelson can assist as an expert witness for powered and manual mobility devices. He has knowledge and experience related to the training of mobility device users and the design, manufacturing, prescription, fitting, and usage of mobility devices. He also has the expertise to assess the environment in which the accident may have occurred.

Sidewalk Assessment

More than 400 miles of sidewalk and a dozen college campuses in 5 states have been  assessed. Allow us to help your city with all your assessment needs.

Wheelchair Testing

Wheelchair Testing

Beneficial Designs, Inc. is the source for your wheelchair testing needs! With our staff consistently participating in annual RESNA meetings and Peter Axelson participating as the Vice-Chair of the RESNA Standards Committee on Wheelchairs, we can insure that your wheelchair will be tested to meet the requirements necessary for Pricing, Data Analysis and Coding (PDAC) and or United States Department of Veterans Affairs (VA) submission. Peter Axelson led the development of the ANSI/RESNA Wheelchair Standards for the US. We are able to perform any wheelchair testing a manufacturer may need in our wheelchair test lab.

  • Description of our testing equipment

    • Drum tester

      • This test devise is made up of two 10 inch diameter drums The drive drum is driven so as to have a surface speed of one meter per second. The wheelchair is balanced over the drums with a swing arm attached to the wheelchair’s rear axles for stability. The purpose of the drum test is to expose the wheelchair to a large number of low-level stresses, similar to stresses experienced during daily wheelchair use.

    • Drop tester

      • The drop test machine is designed to simulate repeated loads experienced by wheelchairs when going down small curbs. This test lifts the wheelchair tw inches and allows it to free fall to a hard surface.


2009 ANSI/RESNA Wheelchair Standards

Centers for Medicare & Medicaid Services (CMS) tests for powered wheelchairs based on anticipated testing requirements with the new 2009 RESNA Standard for Wheelchairs are as follows:


Volume 1: Requirements and Test Methods for Wheelchairs (including Scooters) (Manual Wheelchair Testing)

Section 1         Determine static stability (when required)                                          Est. 2 tests

Section.5         Determine dimensions, mass, and maneuvering space                    Est. 6 tests

Section.7         Measurement of seating and wheel dimensions                                Est. 6 tests

Section.8         Multi drum, drop, static and impact testing (when required)              Est. 8 tests


Volume 2: Additional Requirements for Wheelchairs (including Scooters) with Electrical Systems (Powered Wheelchair Testing)

Section.2         Determine dynamic stability of electric wheelchairs                          Est. 13 tests

Section.4         Energy consumption to determine theoretical distance range           Est. 3 tests

Section 6         Determine maximum speed, acceleration, deceleration                   Est. 2 tests

Section.10       Determine obstacle-climbing ability                                                    Est. 4 tests

Section.14       Testing of power and control systems                                                Est. 2 tests

After the necessary testing has been performed a wheelchair testing report will be produced for your records and for submission to agencies on the mobility device.
