ClinConnect Summary

This clinical trial is looking at a tool called handheld dynamometry (HHD) to measure leg strength in people who have had a stroke for more than three months. The goal is to find out if using HHD can provide more accurate information about leg muscle strength, which can help therapists create better rehabilitation plans. The study will gather data on different types of leg muscle force, which will be useful for understanding how stroke affects strength.

To participate in this study, individuals need to be at least 18 years old and have experienced a stroke more than three months ago. They should also be able to follow simple two-step instructions and assume various testing positions, like sitting or lying down. However, those with certain health issues, such as severe heart problems or infections, may not be eligible. Participants can expect to take part in strength tests while being monitored for their safety, and the information gathered will help improve care for others with similar conditions in the future.
