Summary

Mild Cognitive Impairment (MCI) is defined as an impairment in a single cognitive function, usually memory, other than normal cognitive decline with age, that does not fulfil dementia criteria. Finger movements have been shown to stimulate the sensory-motor and cognitive parts of the cerebral cortex, as well as the supplementary motor area, Broca's area, premotor cortex, and prefrontal cortex, all of which contribute to movement skills. Asymmetrical hand and finger movements done concurrently were proven to improve cognitive processes and cerebral blood flow more than movements performed with one hand.

Detailed description

Cognitive impairment is one of the most pressing healthcare problems of the 21st century. Mild cognitive impairment (MCI) has been defined as a disorder in a single cognitive function; usually, memory is impaired to an extent greater than anticipated for age, yet the patient does not meet the criteria for dementia. MCI, known as a risk factor for the early stage of dementia, constitutes a risk factor for Alzheimer's Disease (AD) and is also known as the prodromal syndrome of AD. MCI affects 3%-22% of people over the age of 65, depending on demographic characteristics, and persons with MCI (PwMCI) progress to dementia at a rate of 10%-15% every year. Advanced age, low education level, and low cognitive capacity are among the most common risk factors for MCI. Although the pathology of MCI is not completely understood, hippocampal and entorhinal cortex atrophy is defined as a hallmark, and the connectivity of the hippocampus with the prefrontal lobe, temporal lobe, parietal lobe, and cerebellum was found to be lower in PwMCI than healthy controls. PwMCI can be categorized as amnestic and non-amnestic MCI. Individuals with non-amnestic MCI have impairments in other domains than memory, such as attention/executive functions (eMCI), which are frequent and disabling symptoms MCI. It was shown that response inhibition, switching, and cognitive flexibility are selectively impaired, while sustained and divided attention are intact in PwMCI. It has been proposed that executive control and gait share common frontal brain circuitry vulnerable to age-related neuropathology. It is known that cognitive deficits are associated with increased fall risk in community-dwelling older adults, and older adults with higher cognitive impairments are more prone to experience falls. The stepping reaction time variability indicate compromised neural circuitry involved in executive function, gait, and posture and increases the risk of fall in PwMCI. A promising avenue in this regard is finger or hand exercise, which is rooted in traditional Chinese medicine and grounded in the meridian theory. The meridian theory suggests that specific meridians and acupoints can be stimulated through finger exercises, leading to the promotion of energy flow and restoration of overall balance within the body. While finger exercise has a historical foundation in traditional Chinese medicine, its potential impact on cognitive function has recently gained attention, resulting in several studies investigating its benefits. Notably, two recent randomized controlled trials (RCT) demonstrated that finger exercise improved cognitive performance in both cerebral ischemic stroke (CIS) and mild cognitive impairment (MCI) patients. Despite the promising nature of finger exercises as an effective cognitive intervention highly accessible to older adults, a thorough investigation of their effects is imperative before widespread application.

Conditions

• Mild Cognitive Impairment

Interventions

Type	Name	Description
OTHER	Bimanual Exercise	The bimanual exercise group consists of exercises that involve movements in which both hands are used simultaneously. The bimanual exercise group will have 40 minutes of training for 3 sessions per week for 8 weeks.
OTHER	Finger Exercise	The finger exercise group consists of exercises that involve finger movements. The bimanual exercise group will have 40 minutes of training for 3 sessions per week for 8 weeks.
OTHER	Virtual Reality	The virtual reality exercise group consists of hand-tracking game exercises that involve finger movements. The bimanual exercise group will have 40 minutes of training for 3 sessions per week for 8 weeks.
