Background:
Hand dexterity is important for daily living activities and can be related to cognitive functions in patients with chronic obstructive pulmonary disease (COPD).
Objective:
The aim of this study was to investigate the relationship between cognitive dysfunction and hand dexterity in patients with COPD.
Methods:
35 COPD patients and 36 healthy individuals were assessed. The Minnesota Hand Dexterity Test and Mini Mental State Examination (MMSE) were used for assessment of cognitive function and hand dexterity.
Results:
Hand dexterity test scores and cognitive function of COPD patients' were significantly lower than the healthy group (p < 0.01). The MMSE scores were negatively correlated with hand dexterity scores in the COPD group (p < 0.05).
Conclusions:
There was a relationship between cognitive function and hand dexterity in the patients with COPD; however, hand dexterity did not alter according to hypoxemia severity. Hand dexterity which is important in daily living activities should be evaluated in greater detail with further studies in COPD patients.
