A data-tracking app records walking metrics. Which metric most directly indicates improved balance and stability?

• A. increased step count per day.
• B. decreased double support time.
• C. longer stride length.
• D. higher walking cadence.

Answer: (B)

Double-support time is the portion of the gait cycle when both feet are on the ground. When balance and stability improve, a person can shift weight more quickly from one foot to the other, spending less time with both feet on the ground. That reduction in double-support time directly signals steadier, more controlled walking and better neuromuscular control. In comparison, increased step count per day measures overall activity and isn’t a direct balance indicator; longer stride length reflects pace and mechanics but not necessarily stability; higher cadence indicates speed of stepping but not balance quality. So, a decrease in double-support time most directly reflects improved balance and stability.
