[NEWS] Not All Manual Wheelchairs are Equal – Determining the Right Classification for your Patient – Rehab Managment

Not all wheelchairs are equal in function and purpose. A wheelchair user’s clinical team is responsible for aligning the user’s needs with appropriate equipment to promote maximum independence and minimize impairments. To do this properly, it’s important to understand Medicare coding of the various classifications of manual wheelchairs.

Nearly all manual wheelchair codes (K0001 – K0004) cover depot or lightweight chairs. These types of chairs are the preferred solution of most insurance providers because they are the most cost effective.

Only ultra lightweight manual wheelchairs fall under code K0005. While chairs in this classification meet RESNA’s standards for stability, dimensions and expected life, they require more explicit and extensive justification for approvals. On the flip side, they have wide-ranging health benefits.

Alexis Miller, OTR, is a former occupational therapist and currently an ATP with Numotion. She believes the documentation is worth it for her patients.

“Considering the impact of pain on independence and quality of life, it is imperative to be fully informed of the benefits of the prescription of ultra lightweight manual wheelchairs,” shared Miller.

[Abstract] Usability Evaluation of a Novel Robotic Power Wheelchair for Indoor and Outdoor Navigation

Highlights

Figure thumbnail fx1

  • Power wheelchair (electric-powered wheelchair [EPW]) users are prone to tips and falls when driving outdoor terrains.
  • Mobility Enhancement roBotic (MEBot) was designed to improve navigational skills of EPW users in common terrains.
  • Active EPW users compared MEBot capabilities to their own EPWs in a driving course.
  • Results demonstrated MEBot’s efficiency and efficacy to drive in all terrains.
  • EPW users recommended semiautonomous applications and an intuitive interface.

Abstract

Objective

To compare the Mobility Enhancement roBotic (MEBot) wheelchair’s capabilities with commercial electric-powered wheelchairs (EPWs) by performing a systematic usability evaluation.

Design

Usability in effectiveness, efficacy, and satisfaction was evaluated using quantitative measures. A semistructured interview was employed to gather feedback about the users’ interaction with MEBot.

Setting

Laboratory testing of EPW driving performance with 2 devices in a controlled setting simulating common EPW driving tasks.

Participants

A convenience sample of expert EPW users (N=12; 9 men, 3 women) with an average age of 54.7±10.9 years and 16.3± 8.1 years of EPW driving experience.

Interventions

Not applicable.

Main Outcome Measures

Powered mobility clinical driving assessment (PMCDA), Satisfaction Questionnaire, National Aeronautics and Space Administration’s Task Load Index.

Results

Participants were able to perform significantly higher number of tasks (P=.004), with significantly higher scores in both the adequacy-efficacy (P=.005) and the safety (P=.005) domains of the PMCDA while using MEBot over curbs and cross-slopes. However, participants reported significantly higher mental demand (P=.005) while using MEBot to navigate curbs and cross-slopes due to MEBot’s complexity to perform its mobility applications which increased user’s cognitive demands.

Conclusions

Overall, this usability evaluation demonstrated that MEBot is a promising EPW device to use indoors and outdoors with architectural barriers such as curbs and cross-slopes. Current design limitations were highlighted with recommendations for further improvement.

[ARTICLE] The Cybathlon promotes the development of assistive technology for people with physical disabilities – Full Text

Abstract

Background

The Cybathlon is a new kind of championship, where people with physical disabilities compete against each other at tasks of daily life, with the aid of advanced assistive devices including robotic technologies. The first championship will take place at the Swiss Arena Kloten, Zurich, on 8 October 2016.

The idea

Six disciplines are part of the competition comprising races with powered leg prostheses, powered arm prostheses, functional electrical stimulation driven bikes, powered wheelchairs, powered exoskeletons and brain-computer interfaces. This commentary describes the six disciplines and explains the current technological deficiencies that have to be addressed by the competing teams. These deficiencies at present often lead to disappointment or even rejection of some of the related technologies in daily applications.

Conclusion

The Cybathlon aims to promote the development of useful technologies that facilitate the lives of people with disabilities. In the long run, the developed devices should become affordable and functional for all relevant activities in daily life.

Keywords

Competition, Championship ,Prostheses, Exoskeletons ,Functional electrical stimulation, Wheelchairs, Brain computer interfaces

Background

Millions of people worldwide rely on orthotic, prosthetic, wheelchairs and other assistive devices to improve their qualities of life. In the US there live more than 1.6 million people with limb amputations [1] and the World Health Organization estimates the number of wheelchair users to about 65 million people worldwide [2]. Unfortunately, current assistive technology does not address their needs in an ideal fashion. For instance, wheelchairs cannot climb stairs, arm prostheses do not enable versatile hand functions, and power supplies of many orthotic and prosthetic devices are limited. There is a need to further push the development of assistive devices by pooling the efforts of engineers and clinicians to develop improved technologies, together with the feedback and experiences of the users of the technologies.

The Cybathlon is a new kind of championship with the aim of promoting the development of useful technologies. In contrast with the Paralympics, where parathletes aim to achieve maximum performance, at the Cybathlon, people with physical disabilities compete against each other at tasks of daily life, with the aid of advanced assistive devices including robotic technologies. Most current assistive devices lack satisfactory function; people with disabilities are often disappointed, and thus do not use and accept the technology. Rejection can be due to a lack of communication between developers, people with disabilities, therapists and clinicians, which leads to a disregard of user needs and requirements. Other reasons could be that the health status, level of lesion or financial situation of the potential user are so severe that she or he is unable to use the available technologies. Furthermore, barriers in public environments make the use of assistive technologies often very cumbersome or even impossible.

Six disciplines are part of the competition, addressing people with either limb paralysis or limb amputations. The six disciplines comprise races with powered leg prostheses, powered arm prostheses, functional electrical stimulation (FES) driven bikes, powered wheelchairs and powered exoskeletons (Fig. 1). The sixth discipline is a racing game with virtual avatars that are controlled by brain-computer interfaces (BCI). The functional and assistive devices used can be prototypes developed by research labs or companies, or commercially available products. The competitors are called pilots, as they have to control a device that enhances their mobility. The teams each consist of a pilot together with scientists and technology providers, making the Cybathlon also a competition between companies and research laboratories. As a result there are two awards for each winning team in each discipline: a medal for the person who is controlling the device and a cup for the provider of the device (i.e. the company or the lab).
