WC19: Wheelchairs Used as Seats in Motor Vehicles

25/11/2014

This month, let’s think about safety, wheelchairs, and transit.  Individuals who remain seated in wheelchairs while travelling in vehicles are “45 times more likely to be injured in a crash than the typical passenger”1 (p. 2).  The “typical” passenger in a vehicle transfers into the vehicle manufacturer’s seat, which is secured to the vehicle, and uses the occupant restraint system; that is, the seat belt system that also is secured to the vehicle.  Individuals who must remain seated in wheelchairs while travelling in vehicles also are at risk of injury in “non-collision events”, such as sudden braking or sharp turning, resulting in the wheelchair tipping, securement failure, or the occupant falling out of the wheelchair1 (p. 4).  Many individuals who must remain seated in the wheelchair during transit do not have postural control or the ability to stabilize themselves or their wheelchairs during these non-collision events, which can result in serious injuries.

Happy Anniversary...

14/10/2014

… to me!  This month marks my 4 year anniversary with Sunrise Medical.  I cannot believe how the time has flown by.  I thought that for this month’s Clinical Corner article I would write something very different and share some of my memorable experiences with Sunrise with all of you.

Maneuverability in Manual Wheelchairs - What Fork to Use?

22/09/2014

There are many factors that influence the maneuverability of manual wheelchairs and I previously have written articles on many of these factors.  Past articles have been written about rolling resistance, overall weight, centre of gravity and weight distribution between the front casters and rear wheels, caster housing position, rear wheel camber, and rear wheel position in standard wheelchairs.  All of these articles are available on Clinical Corner and can be found by using the Search feature in the upper right corner or looking through the tag cloud in the lower right. This month, I would like to focus on one simple choice that affects turning efficiency and performance and that is the choice of the fork in a custom, adjustable folding wheelchair.

The Weight Factor of Manual Wheelchairs

12/08/2014

Previously, I have written about rolling resistance in manual wheelchairs and the many factors that contribute to resistance to rolling in a manual wheelchair.  These factors include the mass of the user and the mass of the system, the weight distribution between the front casters and the rear wheels, and the size and type of casters and tires selected, and the surface on which the wheelchair is used1.  For more information on rolling resistance in manual wheelchairs, please refer to the full blog post here.

Custom Seating

15/07/2014

In previous Clinical Corner articles, I have written about generic off-the-shelf wheelchair cushion design and materials, cushion covers, and wear in wheelchair cushions.  I have also written about customizing off-the-shelf seating to address skin protection, positioning needs or personal choice.  All of these articles can be accessed by either using the search toolbar in the upper right corner or by clicking on the appropriate tag in the lower right corner of the blog.  This month, let’s continue to look at seating with a focus on custom seating.

Front Caster Position in Manual Wheelchairs

23/05/2014

In a previous article, I wrote about the position of the rear wheels of a manual wheelchair and its effects on centre of gravity and weight distribution between the front casters and rear wheels.  This month, let’s focus on how the position of the front casters effects the load distribution between the rear wheels and front casters.

Rolling Resistance in Manual Wheelchairs

25/04/2014

In a previous article, I spoke about rolling resistance in manual wheelchairs.  Let’s take a step back and look more closely at what is meant by the term “rolling resistance” and what factors contribute to the rolling resistance in a manual wheelchair.  Before we look at rolling resistance, let’s have a quick physics lesson

Vertical Rear Wheel Position in Manual Wheelchairs

26/03/2014

​This month, let’s continue our focus on manual wheelchairs by looking at the effects of the vertical rear wheel position in manual wheelchairs.  Both standard and custom folding wheelchairs allow for vertical positioning of the rear wheels.  Positioning the rear wheel up or down the frame of a manual wheelchair will have effects on seat-to-floor height, orientation in space, and rear wheel access.

Centre of Gravity and Manual Wheelchairs

14/01/2014

​Last month, I wrote an introductory article on the different types, or categories, of manual wheelchairs available.  This month, let’s focus on centre of gravity and its application to manual wheelchairs.

The position of the rear wheel on a manual wheelchair relative to the frame effects the position of the centre of gravity and will impact the performance of the wheelchair.  The graphics below illustrate the position of the rear wheel along the horizontal plane, which changes the weight distribution between the rear wheel and the front casters.
