Which of the following is associated with difficulty in gait?

Difficulty in gait often stems from reduced mobility, which can occur for various reasons such as musculoskeletal disorders, neurological conditions, or simply lack of physical fitness. When mobility is compromised, individuals may struggle with balance, stability, and coordination, all of which are critical for an efficient and safe walking pattern. Conditions affecting the joints, muscles, or nervous system can lead to such reductions in mobility, which in turn directly impacts one’s ability to walk normally.

High blood pressure primarily affects cardiovascular health and does not have a direct impact on gait unless it leads to significant physiological issues or complications, such as heart disease, which may indirectly affect mobility. Alterations in skin characteristics, while indicative of various health issues, do not fundamentally influence a person's gait. Increased energy levels generally help promote physical activity, enhancing mobility rather than causing difficulties in gait.

Therefore, reduced mobility is specifically associated with challenges in walking, making it the most appropriate choice among the options provided.
