What is a crucial physical capability for drivers, especially those with rheumatoid arthritis?

Grip strength is a crucial physical capability for drivers, particularly those with rheumatoid arthritis, because this condition often affects the joints in the hands and fingers, leading to pain and limited mobility. Adequate grip strength is essential for effectively controlling the steering wheel, operating the gearshift, and handling other controls within the vehicle. A driver needs to maintain a firm grip to ensure safe driving and quick response to any necessary maneuvers.

While endurance, muscle strength, and flexibility are also important for overall physical functioning, grip strength directly impacts a driver’s ability to manage the vehicle effectively. Optimal grip strength allows for better control, reaction time, and overall safety, which are vital for both the driver and others on the road.
