Rutgers University engineers have modified a home video game, which has shown promise in improving hand function in teenagers with cerebral palsy.
In a pilot trial with three participants, the system enhanced the teens' abilities to perform a range of daily personal and household activities.
The modified system combined a Sony PlayStation 3 console and a commercial gaming glove with custom-developed software and games to provide exercise routines aimed at improving hand speed and range of finger motion.
The Rutgers engineers, who are members of the university's Tele-Rehabilitation Institute, collaborated with clinicians at the Indiana University School of Medicine to deploy systems in participants' homes for up to 10 months.
Grigore Burdea, professor of electrical and computer engineering and director of the Rutgers Tele-Rehabilitation Institute, said:
"Based on early experience, the system engages the interest of teens with cerebral palsy and makes it convenient for them to perform the exercises they need to achieve results."
Each system communicated via the Internet to allow the Indiana and Rutgers researchers to oversee participants' exercise routines and evaluate the effectiveness of the systems. The system is an example of virtual rehabilitation, where patients interact with computer-generated visual environments to perform exercises, and tele-rehabilitation, where patients perform exercises under remote supervision by physical or occupational therapists.
Of course it is essential that the patient remains motivated and challenged to continue exercising and this is where computer games keeps the patient's interest and provides the challenge to continue gross motor movement fitness, strength and balance exercises.
However the WII or play station does not provide isolated and coordinated finger and wrist fine movement training. Instead there is the need for a dedicated rehabilitation glove and software. Research with the Hand Tutor has shown that challenging games and biofeedback provides patients with the motivation to continue intensive repetitive fine motor finger and wrist exercises. The glove is easy and quick to put on even by the patient themselves as it has been designed for rehabilitation and not research.
