Turning Movements Predict Parkinson's Years Ahead
Scientists found that by using small sensors on people's backs, they can measure how quickly someone turns while walking.
They discovered that people who turn more slowly might be at a higher risk of getting Parkinson's disease, a condition that affects movement.
This change in turning speed can be noticed about nine years before a doctor would usually diagnose Parkinson's.
The researchers think this could help find people at risk earlier, which might lead to better treatments and help people stay independent longer.
The study followed over 1,000 people over 50 for ten years and was published in a medical journal called Annals of Neurology.
Study tracked 1,051 participants over 50 for a decade using wearable sensors on their lower backs.
Slower peak angular velocity during turns linked to higher risk of Parkinson's disease.
Turning speeds declined approximately 8.8 years before clinical diagnosis.
Early detection could enable earlier intervention and treatment for Parkinson's.
