This study tests whether a non-invasive brain stimulation technique called rTMS, when combined with standard rehabilitation therapy, can improve leg movement and reduce muscle stiffness in children with spastic diplegic cerebral palsy. About 20 children aged 5 to 18 will receive …

This study tests a treatment called occipital nerve pulsed radiofrequency for people with medication overuse headache. It compares standard care (limiting painkillers and lifestyle advice) to adding the nerve treatment early or as a backup. The goal is to see if the nerve treatme…

This study tests whether adding supervised water exercises to a home workout plan helps people with Parkinson's disease improve their daily activities, walking, balance, and mood. Forty-two adults aged 40-80 with mild to moderate Parkinson's will be randomly assigned to either a …

This study compares two treatments for knee osteoarthritis: functional electrical stimulation (FES) plus exercise versus exercise alone. Researchers will measure muscle strength, pain, and quality of life in 52 adults aged 50-65. The goal is to find which approach works better fo…

This study tests a minimally invasive treatment for cervicogenic headache, a type of headache that starts from the neck. Researchers will use a special needle to deliver short bursts of energy to a nerve in the neck, aiming to reduce pain without damaging the nerve. The study inv…

This study looks at whether letting young boys (ages 3-7) ride a toy car into the operating room instead of being wheeled on a stretcher can lower their anxiety before surgery and reduce confusion after waking up. About 96 children having their tonsils or adenoids removed will ta…
