Considerations for Choosing an Electric Wheelchair
When choosing an electric wheelchair, consider several key factors to ensure the wheelchair meets the user’s needs.
Key Factors to Consider
-
Physical Capabilities: Determine if the user can manage a manual wheelchair for a full day or if they have enough strength to handle it. Those with limited strength or who need help with a manual wheelchair may benefit from an electric model.
-
Mobility Requirements: Assess if the individual needs extra mobility to move on various terrains, including slopes and uneven surfaces. This may require a wheelchair with a specific drive system.
-
Operational Competence: The user should be able to operate the power wheelchair. They need to understand the controls, such as joysticks or keypads, for safe use.
-
Safety Awareness: Ensure the user knows safety protocols, like avoiding obstacles and moving through tight spaces, to operate the wheelchair safely.
-
Prognosis Consideration: Consider the user’s future medical needs. For example, people with progressive conditions like ALS may need wheelchairs with adjustable features, such as power tilt and recline, to accommodate changes in mobility.
-
Adaptability: Choose a wheelchair that can adapt to the user’s changing needs, such as adding leg extensions or a reclining backrest.
-
User Desire: The user’s willingness to use the power wheelchair is important for long-term satisfaction. They should feel comfortable with the device.
-
Customization: Ensure the wheelchair can be customized to the user’s preferences, including adjustable seating, cushioned armrests, and other comfort features.
-
Indoor and Outdoor Use: Consider whether the wheelchair works well in both indoor and outdoor environments, focusing on stability and maneuverability.
-
Portability: For those who travel often, look for lightweight, folding electric wheelchairs that are easy to transport by car, train, or plane.
-
Stability and Anti-Tip Wheels: Ensure the wheelchair has safety features like anti-tip wheels and automatic brakes for added stability.
-

Common Scenarios for Using Electric Wheelchairs
Electric wheelchairs are made to meet a variety of needs, providing important benefits in certain situations. Here are some common scenarios where they are useful:
1. For Individuals with Limited Upper Body Strength
Electric wheelchairs are crucial for users who have difficulty moving manually due to conditions like muscular dystrophy, multiple sclerosis, or spinal cord injuries.
- Key Example: People with tetraplegia or severe range-of-motion limitations benefit from electric wheelchairs, as they do not require upper body strength or coordination.
2. For Postural Support Needs
People with postural deformities or instability may find manual wheelchairs uncomfortable.
- Key Features: Electric wheelchairs with adjustable seating systems, pelvic belts, and other supports help maintain proper posture, providing stability and comfort.
3. To Prevent Upper Extremity Overuse Injuries
Manual wheelchairs can cause strain on the shoulders, elbows, or wrists over time. Electric wheelchairs eliminate the need for repetitive pushing.
- Key Benefit: They reduce the risk of injuries like carpal tunnel syndrome and rotator cuff damage. Power-assist wheelchairs also lower the force needed for movement while still requiring some manual effort.
4. For Pressure Relief and Skin Health
Electric wheelchairs with advanced seating functions help users at risk of pressure sores or skin breakdown.
- Key Features: Functions like tilt-in-space, recline, and seat elevation relieve pressure, reduce shear forces, and allow users to reach higher surfaces for greater independence.
Pricing and Availability
When buying an electric wheelchair, price and availability are key considerations, as costs vary widely depending on the model and features.
