Immersive Virtual Reality for Dual-task Training in Older Adults With Mild Cognitive Impairment: A Randomized Controlled Trial

Summary

Mild cognitive impairment (MCI) is a pre-dementia state marked by a higher risk of conversion to dementia. Presently, strategies to delay the progression of MCI to dementia, such as routine exercise and cognitive activities, are limited and only moderately efficacious. Cognitive-motor dual task training, enhanced in a virtual reality environment, is a novel intervention for individuals with MCI.

Conditions

• Mild Cognitive Impairment

Interventions

OTHER

Cognitive-motor dual task training (DTT)

For session 1 to 3, the training comprises of 4 cycles of the following: 2 min dual tasking, 2 min rest, 2 min dual tasking, 2 min rest. For session 4 to 6, the training comprises of 4 cycles of the following: 2.5 min dual tasking, 1.5 min rest, 2.5 min dual tasking, 1.5 min rest. For session 7 to 14, the training comprises of 4 cycles of the following: 3 min dual tasking, 1 min rest, 3 min dual tasking, 1 min rest. The treadmill speed is maintained at 40%, 50% and 60% of participant's original gait speed at session 1 to 3, 4 to 6, and 7 to 14 respectively. There are 10 levels in the VR game. Participant will start at level 1 of VR game at session 1 and can progress to the next level at the subsequent session if game percentage \> 80%.

OTHER

Cognitive single task training (CSTT)

For session 1 to 3, the training comprises of 4 cycles of the following: 2 min VR gaming, 2 min rest, 2 min VR gaming and 2 min rest. For session 4 to 6, the training comprises of 4 cycles of the following: 2.5 min VR gaming, 1.5 min rest, 2.5 min VR gaming and 1.5 min rest. For session 7 to 14, the training comprises of 4 cycles of the following: 3 min VR gaming, 1 min rest, 3 min VR gaming and 1 min rest. There are 10 levels in the VR game. Participant will start at level 1 of VR game at session 1 and can progress to the next level at the subsequent session if game percentage \> 80%.

OTHER

Motor single task training (MSTT)

For session 1 to 3, the training comprises of 4 cycles of the following: 8 min treadmill walking at 40% of participant's original gait speed followed by 2 min rest. For session 4 to 6, the training comprises of 4 cycles of the following: 8 min treadmill walking at 50% of participant's original gait speed followed by 2 min rest. For session 7 to 14, the training comprises of 4 cycles of the following: 8 min treadmill walking at 60% of the participant's original gait speed followed by 2 min rest.
