What effect does a short limb have on step length?

A short limb typically leads to a step length deficit because the length of the limb directly influences the distance one can cover with each step. When a limb is shorter, the ability to extend the leg forward is reduced, thereby limiting the distance traveled in each stride. This can affect not only the efficiency of movement but also overall gait dynamics and balance.

When considering balance, a shorter limb may require adaptations in one's posture and gait to compensate for a lack of reach. While balance is important in walking, it is not directly improved by a shorter limb. Therefore, the primary impact of a short limb is on the length of each step taken, making it more challenging to achieve a full and normal walking pattern.
