Wheelchairs, seating, and mobility

Manual wheelchairs

Folding frames are common and easy to transport, but flex a little with every push, costing energy over a day. Rigid frames don’t fold at the main joint; they’re lighter and turn more of each push into motion. Ultralight chairs suit daily self-propulsion, with an adjustable axle and low weight that matters for shoulder health over a lifetime. A tilt-in-space chair reclines the whole seat as one unit without changing hip or knee angle — useful for pressure relief without power. Some chairs are pushed by a caregiver instead; many people use both, depending on the day or terrain.

Power wheelchairs

Power bases range from simple models to configured systems with power tilt, recline, and seat elevation — each changes position for a reason: tilt for pressure relief, recline for stretching hips or reflux, elevation for eye-level conversation or safer transfers. Driving doesn’t have to mean a hand joystick: alternative drive controls include head arrays, sip-and-puff systems, chin controls, and switches for people whose hands aren’t the most reliable way to steer. Matching a drive method to how someone moves is core to the evaluation, not an afterthought.

Seating and positioning

The seat and back matter as much as the wheels, sometimes more. Off-the-shelf seating fits a range of bodies reasonably well; custom-molded seating is built around one person’s exact shape, usually for significant asymmetry or high pressure-injury risk. A full system may include a pressure-redistributing cushion plus head, trunk, pelvic, and foot support, each doing a different job. Positioning isn’t just about looking “upright”: the right setup affects how safely someone swallows, how easily they breathe, and how free their hands and eyes are for eating or joining in.

Standers, gait trainers, walkers, and strollers

A stander supports someone in a standing position for a set time even if they can’t stand independently; clinical sources point to weight-bearing time as a factor in bone density, hip development, and circulation, which is why a therapist may build standing into a routine even for a full-time wheelchair user. Gait trainers and walkers support someone building or maintaining walking skills who needs more stability than a cane or hands alone. Adaptive strollers give younger children more head, trunk, and harness support than an off-the-shelf stroller, without being a full wheelchair system.

The mobility evaluation

A physical or occupational therapist typically leads the clinical side — movement, posture, function, and goals. Learn what physical therapy can address, or what occupational therapy can address. Alongside the therapist, look for a supplier whose staff hold the RESNA ATP (Assistive Technology Professional) credential, recognizing competence in assessing needs and matching them to technology. RESNA’s SMS (Seating and Mobility Specialist) credential is a narrower specialty in seating and positioning. Neither is required everywhere, but both signal the person configuring complex equipment has been tested on it.

Complex rehab technology vs. standard equipment

Complex Rehab Technology (CRT) is the industry’s term for individually configured wheelchairs, seating, standers, and gait trainers built for someone with a significant, primarily physical diagnosis — evaluated by a team including a physician, a PT or OT, and a credentialed rehab technology professional. It’s provided differently than standard, off-the-shelf durable medical equipment (DME): more documentation of medical necessity, through a specifically accredited supplier. Before any purchase, ask for a trial with the actual equipment, not a catalog photo — fit rarely comes through on paper.

Growing into and out of equipment

Pediatric frames are often built with growth in mind — adjustable depth, width, and height that buy a few years before full replacement — but “growable” still has limits. Watch for a seat that’s become too narrow, footrests that no longer support the feet, or a visibly outgrown chair, and don’t wait for a scheduled recheck to say something. Adults aren’t exempt either: weight changes, a new diagnosis, surgery, or a progressive condition are all reasons to ask for reassessment.

Pressure injuries and skin health

Sitting in one position for a long time concentrates pressure over bony areas, and unrelieved pressure can damage skin and the tissue underneath — what clinicians call a pressure injury. General prevention includes a cushion suited to the person’s risk level, a consistent schedule of weight shifts or repositioning, and regular skin checks, especially for anyone who can’t reliably feel or report discomfort. This is general information, not a skin-care plan — a physician, PT, or OT should guide cushion choice and repositioning schedule for anyone at elevated risk.

Riding safely in a vehicle

Not every wheelchair doubles as a vehicle seat. Chairs tested and labeled as a WC19 “transit option” have been crash-tested with a four-point strap-type tiedown system and, where applicable, a vehicle-anchored lap-and-shoulder belt — the current standard for securing a wheelchair in a moving vehicle, including school buses and transit. If someone will regularly ride seated in their wheelchair rather than transferring to a vehicle seat, ask specifically whether the chair is WC19-compliant and the vehicle has compatible tiedowns, before assuming any combination is safe.

Repairs, replacement, and whose choice this is

Broken equipment is common, and a plan for fast repairs matters as much as the original purchase — see our equipment repair guide for what to do when a chair breaks down. And regardless of age or communication style, the final say belongs to the person using the equipment as much as possible: adults choose their own chair, and a nonspeaking person is still who the equipment is for — ask them, watch them, and build decisions around their responses, not around what looks easiest for everyone else.

• Is the person configuring this equipment a credentialed ATP or SMS?
• Can we trial the actual equipment before committing to it?
• How much room does this setup have for growth, and when should we recheck?
• What is our plan for pressure relief and skin checks?
• Is this wheelchair WC19-rated for riding inside a vehicle, if we need that?
