Abstract:

Background: COPD is characterised by irreversible airflow obstruction, which brings about hypoxemia, hypoxia and cerebral hypo-perfusion leading to cognitive impairments and peripheral muscle dysfunctions which get worse with the severity of the disease.
Purpose: Cognitive reaction time that forms the pre-motor event of the reaction time loop has been seen to be slower in COPD as compared to healthy controls. But the motor event of the loop has not been assessed in this population. The present study aimed at assessing the lower limb reaction time in COPD subjects.
Materials and Methods: 30 male COPD subjects (GOLD criteria) were included in the study. The study was a single blinded experimental observation design. Lower limb reaction time was calculated using a simple reaction time software accurate up to 0.1 millisecond.
Analysis:  Mean, standard deviation of the demographic data (age, height and weight) and the reaction time was calculated using Microsoft Excel. One-way ANOVA was used to test for statistical significance between the means of the three groups(mild, moderate and severe) COPD.
Results: The difference of means between the three groups was statistically significant (p=0.001). Although the correlation between severity and lower limb reaction time was not statistically significant, there was an association between the two parameters.
Conclusion: This study shows an association between lower limb reaction time and severity. Lower limb reaction time has been found to follow a trend as the severity of the disease increases.
Implication: There arises a need for incorporating balance training and for improving lower limb reaction time as a part of pulmonary rehabilitation in COPD subjects.
KEY WORDS: COPD, Reaction time, Cognitive deficits.
