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

May 8, 2024 updated by: Fong Chin Su, National Cheng-Kung University Hospital

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

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Oxygenated hemoglobin (HbO)
Time Frame: 1 hour
The Oxygenated hemoglobin (HbO) was measured while the participants play the game under both conditions
1 hour
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
1 hour
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
1 hour

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
5 minutes
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
5 minutes
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
5 minutes
