One common problem experienced with wheelchairs is related to their mechanical components and overall functionality. Here are some common issues wheelchair users may encounter:

1. Wheel Alignment: Wheelchairs may experience misalignment of the wheels over time, leading to uneven wear and difficulty maneuvering. This can be caused by regular use, rough terrain, or improper maintenance.

2. Brake Problems: The brakes on wheelchairs may become loose, worn out, or fail to engage properly, posing a safety risk for users. Regular inspection and adjustment of brakes are essential to ensure optimal performance.

3. Seat Cushion Wear: The seat cushion on wheelchairs may wear out over time, losing its supportive properties and comfort. This can lead to discomfort, pressure sores, and reduced sitting tolerance for users.

4. Frame Damage: Wheelchair frames may become damaged or bent due to accidents, collisions, or heavy use. This can compromise the structural integrity of the wheelchair and affect its stability and safety.

5. Wheel Wear and Tear: The wheels and tires on wheelchairs may wear out over time, especially if used frequently on rough or uneven surfaces. Worn-out wheels can affect traction, maneuverability, and overall performance.

6. Battery Issues (for powered wheelchairs): Powered wheelchairs may experience battery-related problems, such as insufficient charge, battery degradation, or electrical issues. This can lead to reduced range, power loss, or complete wheelchair shutdown.

7. Folding Mechanism Malfunction: Folding wheelchairs may experience issues with their folding mechanisms, such as sticking, jamming, or difficulty locking into place. This can make transportation and storage challenging for users.

8. Armrest and Footrest Damage: Armrests and footrests on wheelchairs may become loose, damaged, or uncomfortable over time. This can affect user comfort and support while sitting in the wheelchair.

Regular maintenance, inspections, and repairs by qualified technicians are essential to address these common problems and ensure the safe and reliable operation of wheelchairs for users. Additionally, proactive measures such as proper use, storage, and handling can help prevent some of these issues from occurring.
