EVIDENCE-BASED REHABILITATION
We believe that effective clinical care must be backed by solid scientific evidence. By utilizing proven protocols like CTAR and advanced data-driven tools like sEMG Biofeedback, our clinical directors focus on helping patients safely improve their swallowing functions, lower choking risks, and work toward transitioning away from feeding tubes back to regular meals.
