Rationale: When using a cane, it is crucial to move the cane forward first to provide support and enhance balance. Advancing the cane before the weaker or stronger leg helps widen the base of support, thereby improving stability during ambulation. Keeping the cane too far or too close to the body can affect its supportive function. Moreover, utilizing the cane solely for stair climbing limits its overall utility in maintaining balance and stability during regular walking.
