Clinical trials

This study is done to assess the change in confidence level, knowledge, and diagnostic ability in TMD-related aspects through the exposure to a Virtual Patient-Based Learning (VPBL) platform featuring temporomandibular disorder (TMD) cases among 3rd and 4th year predoctoral dental students at a larger predoctoral school.

This longitudinal study will investigate effects of exercise participation in Southwest Native American adolescents, ages 11-17, from the Gila River Indian Community. Vital signs, physical activity participation adherence, physical performance measures, and psychological/social measures will be assessed. Participants will attend one educational presentation for the initial session, explaining the benefits of physical exercise and expectations throughout the program. Baseline measurements for strength, flexibility, and cardiovascular fitness will be taken as well as height, weight and blood pressure. Based on individual performance measures, each participant will be provided a personalized exercise program to complete 3-4 times/week for the duration for the duration of the study. Participants will also be provided an exercise journal to track their adherence to their exercise program each week. At the end of the session parents and adolescents separately will be asked to complete a written survey assessing physical, emotional, social, and school function. Physical performance measures will be taken every other week from the initial education and data collection session through 6 weeks.

The goal of this randomized controlled trial is to investigate the effectiveness of non-invasive brain stimulation in treating adults with amblyopia. The main questions it aims to answer are: 1. What are the effects of non-invasive brain stimulation on neuronal plasticity in the visual cortex of adults with amblyopia, and does it produce lasting changes? 2. Do cumulative sessions of non-invasive brain stimulation influence neural plasticity and higher-order visual functions in adults with amblyopia? The investigators hypothesize that non-invasive brain stimulation will show a positive cumulative effect after five (5) consecutive days of stimulation on visual perception and function in adults with amblyopia. Participants will be randomized into one of two treatment groups: 1. High-frequency transcranial random noise stimulation (hf-tRNS). 2. Sham stimulation. Researchers will compare baseline measurements of crowded visual acuity, contrast sensitivity, stereoacuity, phosphene thresholds, global motion perception, form pattern recognition and pattern-reversal visual evoked potentials (VEPs) to post-treatment measurements for each group.

The goal of this randomized controlled trial is to test the effectiveness of non-invasive brain stimulation in treating adults with symptomatic convergence insufficiency compared to vergence/accommodative therapy. The main questions it aims to answer are: 1. Can non-invasive brain stimulation shorten the treatment time of office-based vergence/accommodative therapy for convergence insufficiency? 2. Is non-invasive brain stimulation alone just as effective as office-based vergence/accommodative therapy in treating convergence insufficiency? The investigators hypothesize that non-invasive brain stimulation will shorten the treatment time from 12 weeks to 8 weeks of office-based vergence/accommodative therapy and that non-invasive brain stimulation alone would be equally effective as office-based vergence/accommodative therapy in improving symptomatic convergence insufficiency. Participants will be randomized into one of three treatment groups: 1. Non-invasive brain stimulation with office-based vergence/accommodative therapy. 2. Sham stimulation with office-based vergence/accommodative therapy. 3. Non-invasive brain stimulation only. Researchers will compare baseline measurements of near point of convergence (NPC) and positive fusional vergence (PFV) to post-treatment measurements for each group.
