What You Need to Know Before You Apply

What is the purpose of this trial?

This trial will test if injecting a special substance from a patient's own blood into their vocal cords can help improve voice problems caused by aging or damage. The treatment aims to use the body's natural healing abilities to repair and strengthen the vocal cords.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment Serial PRP injections?

Research shows that platelet-rich plasma (PRP) injections can help reduce pain and improve function in people with knee osteoarthritis, and similar benefits have been observed in treating shoulder conditions. This suggests that PRP injections might be effective for other joint-related issues as well.12345

Published Research Related to This Trial

Autologous platelet-rich plasma (PRP) injections significantly improve pain relief and functional outcomes in patients with common shoulder diseases compared to placebo and corticosteroid injections, based on an analysis of 17 randomized controlled trials.
PRP injections also enhance quality of life (QoL) for patients, with the most effective results seen when PRP is prepared using specific techniques, such as double centrifugation and high platelet concentration.
