Final answer:
A decrease in right step length can be caused by decreased tolerance to standing on the right leg due to pain, decreased standing and walking balance, and decreased leg strength. All of these factors may impact the length of steps and overall gait.
Step-by-step explanation:
Factors Contributing to a Decrease in Right Step Length
Factors that could contribute to a decrease in right step length include:
- Decreased tolerance to standing on the right leg due to pain: If standing on the right leg causes pain, a person may unconsciously shorten the step length on that side to reduce discomfort.
- Decreased standing and walking balance: Balance is crucial for maintaining a stable gait. A decrement in balance can lead to shorter steps as the body tries to prevent falls.
- Decreased leg strength: Strong leg muscles are needed for making long strides. Weaker muscles may not be able to support longer steps, resulting in a shorter step length.
All of the above factors can individually or collectively cause a decrease in step length on the right side. It's also important to consider body mechanics, including one's center of gravity and base of support when evaluating gait changes.
