Measuring leg strength in stroke patients using handheld devices
Use of Hand-held Dynamometry to Obtain Objective Measures of Lower Extremity Rate of Peak Force Production, Cumulative Peak Force Production, and Sustained Peak Force Production Among Patients With Chronic Stroke
Vanderbilt University Medical Center · NCT05941962
This study is testing a handheld device to see if it can accurately measure leg strength in people who have had a stroke to help improve their rehabilitation.

What this trial studies
This observational study aims to evaluate the effectiveness of handheld dynamometry (HHD) in assessing leg strength among individuals with chronic stroke. By collecting objective measures of muscle force production, the study seeks to provide therapists with accurate data to enhance rehabilitation strategies. Participants will undergo strength assessments for various muscle groups while positioned in specific ways to ensure reliable results. Data will be securely logged and analyzed to establish normal values for muscle strength in this population.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 18 years or older who have experienced a stroke more than three months prior and can follow simple commands.
Not a fit: Patients with severe lower extremity contractures or significant cardiovascular issues that contraindicate exercise may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved rehabilitation outcomes for stroke patients by providing therapists with more accurate strength assessments.
How similar studies have performed: While the use of handheld dynamometry is established in other contexts, this specific application in chronic stroke patients is relatively novel.
