This study looked at 40 children aged 7 to 17 who needed bone graft surgery for their jaw. Doctors compared two ultrasound-guided pain-block methods to see which one reduced pain and the need for strong pain medicine better in the first 24 hours after surgery. The goal is to find…

This study tested whether playing virtual reality games with a headset could help people who had a stroke more than 6 months ago improve arm and hand function. Fifteen chronic stroke patients with arm weakness participated. The results will show if this fun, immersive approach ca…

This study tested a wearable ear device that sends gentle electrical pulses to a nerve to help control appetite. Sixty healthy adult women each had two visits: one with the device on and one with it off. Researchers measured how much they ate, their hunger levels, and food cravin…
