Understanding how fatigue affects fall risk in adults with knee osteoarthritis

Muscle Fatigability and Trip-specific Fall Risk in Adults With Knee Osteoarthritis

NA · University of Delaware · NCT06229691

This study is testing if feeling tired affects the chances of falling while walking in adults aged 55-70 with knee osteoarthritis compared to those without it.

What this trial studies

This clinical trial investigates the relationship between muscle fatigability and the risk of falling in adults aged 55-70 years, specifically comparing those with knee osteoarthritis to those without. Participants will engage in a 30-minute treadmill walk and undergo various assessments, including questionnaires, physical activity monitoring, mental fatigue tests, strength testing, and balance evaluations. The study aims to determine if fatigue increases the likelihood of tripping and falling while walking. By analyzing the data, researchers hope to identify specific factors that contribute to fall risk in this population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 55-70 years with knee osteoarthritis experiencing occasional to frequent knee pain.

Not a fit: Patients with recent fractures, surgeries, or significant neurological or cardiovascular conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved fall prevention strategies for older adults with knee osteoarthritis.

How similar studies have performed: While there have been studies on fall risk in older adults, this specific focus on fatigue and knee osteoarthritis is relatively novel.
