How do disability or mobility differ from flexibility?

• A. Flexibility is tissue length and extensibility; mobility is the ability to move joints through ROM with control and coordination.
• B. Flexibility is strength; mobility is speed.
• C. Flexibility is neuromuscular control; mobility is tissue length.
• D. Flexibility is the ability to move joints; mobility is flexibility.

Answer: (A)

The main concept here is distinguishing tissue properties from movement ability. Flexibility refers to how long and extensible the soft tissues are—muscles, tendons, ligaments, and fascia—and describes passive length. Mobility is about the ability to move a joint through its full range of motion with proper control, coordination, and stability provided by the neuromuscular system. That’s why the best answer describes flexibility as tissue length and extensibility, while mobility is the capacity to move joints through ROM with control and coordination. The other options mix up these ideas or substitute unrelated attributes like strength, speed, or neuromuscular control for tissue length, which doesn’t capture the distinct roles of flexibility vs mobility.
