Selecting the right wheelchair is as clinical a decision as choosing a medication. An ill-fitted chair causes pressure sores, postural deformity and caregiver fatigue. Begin by involving both the patient and a physiotherapist in the selection — their combined input on seating width, footrest height and backrest angle will guide you far better than any generic size chart.
Manual wheelchairs are the right choice for patients who retain upper body strength or have caregivers available for pushing. Self-propelling models with larger rear wheels suit active users. Attendant-propelled models, with smaller rear wheels, are lighter and easier for caregivers to manoeuvre in tight home spaces like corridors and bathrooms.
Electric (power) wheelchairs are indicated when the patient has limited arm strength or endurance — as seen in progressive conditions like MND, advanced MS or high spinal injuries. They offer joystick or breath-controlled operation, far greater independence and better long-term outcomes for active patients. The trade-off is higher cost, greater weight and the need for a charging routine.
Seat width should allow 2-3 cm of clearance on each side of the hip. Seat depth should leave 5 cm between the back of the knee and the front of the seat. Footrest height should allow the thigh to rest flat with 90° knee flexion. Most standard manual chairs have a 45–48 cm seat width, which suits the majority of adults — but bariatric models accommodating up to 300 kg are available.
Consider the home environment before choosing. Doorways narrower than 70 cm require a hemi or narrow-width chair. Thick carpets and uneven surfaces favour larger-diameter drive wheels. For regular outdoor use, choose pneumatic (air-filled) tyres over solid tyres for a more comfortable ride on rough terrain.
