Scientists Develop Therapeutic At-home 3D Video Game for Stroke Patients

Therapeutic at-home gaming program for stroke patients has been developed by researchers. Constraint-induced movement therapy (CI therapy) is an intense treatment recommended for stroke survivors, and improves motor function, as well as the use of impaired upper extremities. However, less than 1 percent of those affected by hemiparesis receives the beneficial therapy. "Lack of access, transportation and cost are contributing barriers to receiving CI therapy. To address this disparity, our team developed a 3D gaming system to deliver CI therapy to patients in their homes," said Lynne Gauthier, assistant professor of physical medicine and rehabilitation in Ohio State's College of Medicine.

Gauthier, also principal investigator of the study and a neuroscientist, is collaborating with a multi-disciplinary team comprised of clinicians, computer scientists, an electrical engineer and a biomechanist to design an innovative video game incorporating effective ingredients CI therapy.

For a combined 30 hours over the course of two weeks, the patient-gamer is immersed in a river canyon environment, where he or she receives engaging high repetition motor practice targeting the affected hand and arm. Various game scenarios promote movements that challenge the stroke survivor and are beneficial to recovery.

To ensure that motor gains made through the game carry over to daily life, the game encourages participants to reflect on their daily use of the weaker arm and engages the gamer in additional problem-solving ways of using the weaker arm for daily activities.

Gauthier said that this novel model of therapy has shown positive results for individuals who have played the game. Gains in motor speed, as measured by the Wolf Motor Function Test, rival those made through traditional CI therapy.

The researcher added that it provides intense high quality motor practice for patients, in their own homes. Patients have reported they have more motivation, time goes by quicker and the challenges are exciting and not so tedious.
