Modeling muscle strength in patients with motor impairments

Study for the Development and Evaluation of Personalised Muscle Effort Generation Models for Patients With Upper Limb Motor Deficits

Not applicable Interventional Pôle Saint Hélier · NCT06608121

This study is trying to understand how people with upper limb motor impairments can use their muscles by measuring their strength at different speeds and angles to help improve rehabilitation and robotic assistance.

What this trial studies

This study focuses on developing mathematical models to describe the residual muscle forces in patients with upper limb motor impairments caused by conditions such as stroke, multiple sclerosis, and spinal cord injuries. By measuring upper limb isokinetic forces, the study aims to understand how these patients can generate voluntary muscle force depending on joint angle and motion speed. The findings could inform rehabilitation strategies and assist in creating robotic systems that adapt to the patients' remaining capabilities.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 with motor deficits due to stroke, multiple sclerosis, or spinal cord injuries.

Not a fit: Patients with severe spasticity, cognitive impairments, or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance rehabilitation techniques and improve the quality of life for patients with motor impairments.

How similar studies have performed: While similar approaches have been explored, this specific modeling of muscle strength in impaired patients is relatively novel.
