Effects of Adding Force Control to a VR Game on Brain Activation

One of the major contributor for the lower quality of living in the aged population, is the reduction in hand function. To mitigate this, several virtual-reality based hand rehabilitation/training systems have been developed.

However, most of these systems are solely controlled by hand gestures, and do not incorporate the force between the fingertips. Which is not the case for grabbing things in real life. With that in mind, the researchers assumed that a virtual-reality based hand rehabilitation/training system that incorporates force control into its input can be more beneficial in terms of recovering one's hand function.

To test out this claim, subjects were recruited and tasked to play a game using both input systems (wfc and wofc), while their brain activity while using both input system was simultaneously recorded using functional near infrared spectroscopy and compared

Treatment and study plan

Virtual Reality Headset

Device

Meta-Quest 2 virtual reality headset was used in this study

Primary outcomes

  1. Oxygenated hemoglobin (HbO)

    Time frame: 1 hour

    The Oxygenated hemoglobin (HbO) was measured while the participants play the game under both conditions

  2. Game performance1 (Amount of grasp initiated)

    Time frame: 1 hour

    This unitless metric counts the number of times the subject initiates a grasp while playing the game, a higher amount of grasp initiated signifies worst performance

  3. Game performance2 (Memory task accuracy)

    Time frame: 1 hour

    This percentage is calculated by dividing the amount of correct response by the total amount of response. A larger perrcentage represents better performance

Secondary outcomes

  1. Manual dexterity

    Time frame: 5 minutes

    The manual dexterity of each participant was measured using the Purdue Pegboard Test at the beginning of the experiment

  2. Maximum voluntary pinch force

    Time frame: 5 minutes

    The maximum voluntary pinch force of each particapant were measured using the Jamar pinch dynamometer at the beginning of the experiment

  3. Recall

    Time frame: 5 minutes

    The ability to recall information of each particapant was measured using the forward digit span test at the beginning of the experiment
