ClinConnect Summary

This clinical trial is looking at how the muscles and tendons in the calf behave during walking in people who have had a stroke or a spinal cord injury. Researchers want to understand how the length of these muscles and tendons changes when a person walks, especially during the stance phase, which is when the foot is on the ground. They will compare the movement in these patients to that of healthy individuals to see how it differs.

To participate, individuals must be adults who have had a stroke at least a week ago or have an incomplete spinal cord injury, with some ability to move their legs. Those who are healthy and have no neurological issues are also welcome to join the study. Participants will undergo tests that include ultrasound imaging and 3D gait analysis, which will help the researchers gather detailed information about their walking patterns. It's important to note that certain medical histories, like recent surgeries or specific health conditions, might exclude someone from participating.
