Rigid frame wheelchairs offer some choice in the type of frame – from open frame to closed frame and from fully welded to models with fold-down back canes. Some models of rigid wheelchairs provide adjustability in the rear axle while others are fully fixed. Rigid frame wheelchairs promote efficiency of propulsion due to their light-weight design and minimization of moving parts, which allows for more efficient propulsion. A thorough assessment is required in order to match the needs of clients with the products that are available on the market for optimal fit, function and performance.

There is never going to be one model of wheelchair that is right for every client. Manufacturers recognize this and often provide several models of wheelchairs within a category to meet the various needs and demands of clients. This allows for optimizing both fit and function for a client through the selection of an appropriate model of wheelchair. How we choose between models of wheelchairs goes back to the assessment and then matching the goals of seating and mobility with the choices that are available.

The Clinical Corner article, Manual Mobility: The Basics, describes the different categories of manual wheelchairs, known generically as transport, standard, custom folding, custom rigid and tilt-in-space. It was noted that the more rigid the wheelchair, the easier it is to propel the chair as rigidity decreases flex in the frame of the chair. The ideal is that all of the energy of propulsion is translated into movement as any frame flex is lost movement. The more rigid the wheelchair, the more efficient the propulsion can be.

There are many factors that influence the maneuverability of manual wheelchairs and I previously have written articles on many of these factors. 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.

This month, let’s focus on one of the factors that influences rolling resistance: mass of the system, which includes not only the wheelchair, but also the seating system.

In our focus on manual wheelchairs, we have looked at the effects of horizontal and vertical rear wheel position in manual wheelchairs. This month, let’s look at lateral position and camber in the rear wheels of custom folding and rigid frame wheelchairs.

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.

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.

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.

Last month, I wrote about centre of gravity and its application to different types of manual wheelchairs. This month, I would like to address an important consideration related to centre of gravity when prescribing standard wheelchairs.

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.

This month, let’s go back to the basics and look at the different types of manual wheelchairs available. As I have written in a previous Clinical Corner article, funding agencies for mobility devices vary province by province in Canada and each agency has different criteria on who is eligible to receive a manual wheelchair and which type or category of manual wheelchair can be considered for a qualified individual.
