## 4 Discussion  
The present study explored the possibility of using motor and sensory parameters and components to predict the cognitive score of community-dwelling older Korean men. This was performed to explore an alternative to neuropsychological testing methods, which would allow early detection of cognitive deterioration. The demographics analysis showed that age and education were highly correlated with the K-MoCA score as previous studies have consistently shown [33; 34; 35]. Age independently accounted for close to 6% of MoCA score variance, whereas years of education accounted for almost 16% of the variation. In contrast, the SMCQ score did not correlate with the cognitive score. Similar results have been previously shown by studies reporting that subjective complaints and informant reports oftentimes have inconsistent correspondence with current objective cognition [36; 37]. The history of illness results showed significantly lower cognitive performance only among the people who had previously suffered a stroke. Cognitive deterioration and impairment have been reported as common occurrences after a stroke [38]. There was no significant difference in cognitive scores between participants with hypertension, diabetes mellitus or cardiovascular disease (CVD) and those without.

Positive correlations are presented in blue, and the negative correlations are presented in red. Regarding the participants' habits, cognitive performance was found to be higher among people who reported receiving regular ophthalmological examinations. This is in accordance with the previous research, which reported untreated poor vision as a risk factor for dementia [39] and that patients with dementia used less visual correction, had fewer ophthalmological treatments, and underwent fewer ocular surgeries [40]. Participants who reported consuming alcohol on a daily basis had higher cognitive scores than those who did not or occasionally had a drink. Upon further investigation, it was observed that the all of the six participants who consumed alcohol daily reported receiving regular ophthalmological testing and none had a history of neurovascular disease. Additionally, recent research has shown that maintaining mild to moderate daily alcohol consumption or initiating mild daily alcohol consumption was associated with decreased risk of dementia [41]. The impact of daily alcohol consumption on cognitive performance should be further investigated. The gait variables significantly correlated with the cognitive score accounted for 2-4% of its variance. Stride length, which has been reported as a differentiating factor for cognitive status [7; 8] was observed to be correlated with cognitive performance. Stance duration variability has been previously observed as directly related to central nervous system impairment which was measured using neuropsychological examinations [42]. Additionally, previous research observed a high correlation between overall gait variability and the MoCA score [43; 44]. The present study observed a significant correlation only in the case of stance duration variability, which could be due to a smaller range of cognitive scores of the participants included in the study. These results present the possibility that not all of the gait disturbances reported in previous studies on dementia are present in people without severe cognitive deterioration. In the case of loading response, the objectives of this phase of the gait are limb stabilization, shock absorption, and preservation of the body's progression. During loading response, the knee flexes so that the shock from the foot falling flat on the ground can be absorbed, assuring stabilization and preparing for single limb support. Intra-individual variability of this phase could signify inconsistency in dynamic stability.
