Gentle brain zaps may help stroke survivors regain spatial awareness
Disease control CompletedThis study investigates whether a noninvasive brain stimulation technique called transcranial direct current stimulation (tDCS) can enhance recovery from spatial neglect — a condition where stroke survivors ignore one side of their world. Participants who had a stroke 3 to 12 mon…

Simple ankle exercises improve balance in stroke survivors
Disease control CompletedThis study tested whether special ankle exercises could improve balance and walking in people who had a stroke at least a year ago. 140 participants were split into two groups: one did the ankle training plus standard gait training, the other did standard gait training alone. Aft…

Can brain zaps boost social skills in kids with autism?
Symptom relief CompletedThis study tests whether 80 sessions of a gentle brain stimulation technique called tDCS, given over 12 months, can improve attention, social skills, and language in 180 children aged 6 to 11 who have autism along with rare diseases, genetic problems, or PANDAS. The treatment is …

Sound therapy may help stroke patients regain spatial awareness
Symptom relief CompletedThis study tests a new therapy that uses moving sounds to help stroke survivors with spatial neglect — a condition where they ignore one side of space. 18 participants will either get standard rehab or standard rehab plus dynamic auditory cueing for 4 weeks. The goal is to see if…
