What is it about?
Measuring how stroke affects walking or ambulation using motion analysis looks promising compared to traditional clinical scales. In reality, the results are often complicated because so many different metrics have been reported. The dynamic gait index, angular component of the coefficient of correspondence (ACC), change in cadence, stride length, and hip range of motion have shown reliable validity. However, most studies so far are only of moderate quality, and there is still a lot of variation in how measurements are done.

Why is it important?
Instrumented gait assessment using wearable sensors and computer vision has become widely available beyond the traditional research labs. One can argue that modern technology can make the assessment more precise and reliable. However, to make such technology truly useful in clinics, more high-quality research is needed to confirm which metrics are the most trustworthy and practical.
Perspectives
From my perspective, using motion analysis to understand how stroke affects walking is very promising, especially because it can capture details that simple checklists often miss. Still, I often find the different outcome measures confusing, and it makes it hard to compare results across studies.
