What is the primary clinical observation of a person showing an antalgic gait?

An antalgic gait is characterized by a very short stance phase on the affected leg. This adaptation occurs as a response to pain, where the individual attempts to minimize weight bearing on the painful side to alleviate discomfort. Consequently, during walking, the individual will shorten the time spent in the stance phase, where that leg is in contact with the ground, and increase the time spent in the swing phase, allowing the affected leg to be off the ground more often.

This gait pattern is directly related to pain management, and it is a common compensatory mechanism for those experiencing conditions like arthritis, injuries, or other painful musculoskeletal issues. The focus on minimizing pain leads to this altered gait pattern, reinforcing the idea that the stance phase is not prolonged, as doing so would typically exacerbate discomfort.

The other options do not accurately describe the hallmark of an antalgic gait, as they either suggest increased weight bearing or improved movement coordination, which do not align with the primary observation of this specific gait abnormality. An understanding of gait mechanics and the body's compensatory responses to pain is essential for orthotic fitters and related healthcare professionals when assessing and designing appropriate interventions for those displaying an antalgic gait.
