Background: Gait speed, a vital sign of health and functional capacity, is commonly used to measure mobility. Although studies have assessed gait speed in older adults and individuals with chronic obstructive pulmonary disease (COPD) separately, few have evaluated gait speed in older adults with COPD. Therefore, the primary objective of our study was to determine the threshold point for the 4-meter gait speed test (4MGS) to better discriminate between functional exercise capacity and health status in older patients with COPD. The second objective was to determine possible predictors of gait speed. Methods: In this cross-sectional study, we assessed participants’ pulmonary function, dyspnea, health status (COPD Assessment Test [CAT]), gait speed (4MGS), functional exercise capacity (6-minute walk test [6MWT]), and physical activity. Results: Forty-five older patients with COPD participated in this study. The predicted 6MWT and CAT scores were independent and significant determinants of the 4MGS score, explaining 54% of the variance (p<0.001). We identified gait speeds of 0.96 m/s and 1.04 m/s as thresholds to predict abnormal functional exercise capacity (sensitivity 85% and specificity 56%) and impaired health status (sensitivity 90% and specificity 69%), respectively (p<0.05). Conclusion: Our findings demonstrated that gait speed can discriminate between abnormal functional exercise capacity and impaired health status in older patients with COPD. Moreover, functional exercise capacity and health status are predictors of gait speed.

Background: Inspiratory muscle training (IMT) is a commonly used exercise method for both patients with chronic obstructive pulmonary disease (COPD) and the older adult population. In addition to their primary function, respiratory muscles play an active role in core stabilization. However, no IMT program includes both of these functions (i.e., core stabilization and postural control functions as well as respiration). This study investigated the effects of a newly integrated exercise program, termed “functional IMT,” in geriatric individuals with and without COPD. Methods: This prospective and experimental study included 45 geriatric individuals with COPD (n=22) and without COPD (n=23). The training program consisted of 4 weeks of conventional IMT followed by 4 weeks of functional IMT. Respiratory muscle strength, symptoms, exercise capacity, balance, postural control, physical activity, and quality of life were evaluated. Results: After training, respiratory muscle strength, symptoms, exercise capacity, balance, postural control, and quality of life improved in both groups (p<0.05). In addition, physical activity was increased in the COPD group (p<0.05). We observed no statistically significant difference in outcomes between the two groups before and after treatment (p>0.05). Conclusion: The gains were similar in both groups. Functional IMT, which is an integrated approach that includes all respiratory muscle functions, is a safe, effective, and innovative method for use in geriatric individuals with and without COPD.

Purpose: To evaluate the effects of idiopathic infantile nystagmus (IN) and bilateral ametropic amblyopia on metabolitesin the occipital cortex by magnetic resonance spectroscopy. Methods: The children included in this prospective study were divided into three groups. Group 1 consisted of11 patients with idiopathic IN, group 2 consisted of 10 patients with bilateral ametropic amblyopia and group3 consisted of nine normal children. A single-voxel magnetic resonance spectroscopy examination was performedby placing a region of interest on the occipital cortex of each participant. N-acetyl aspartate (NAA),creatine (Cr) and choline (Cho) concentrations were measured in the occipital cortex. This was followed bycalculating and comparing the NAA/Cr and Cho/Cr ratios between the three groups. The Kruskal-Wallis test,Mann-Whitney U-test, and chi-square test were used for statistical analysis. Results: There was no statistically significant difference in NAA/Cr ratios between patients with idiopathic INand normal children, but there was a statistically significant difference between these groups when Cho/Crratios were compared; the ratio was higher in the idiopathic IN group. There were no statistically significant differencesin NAA/Cr or Cho/Cr ratios between patients with bilateral ametropic amblyopia and normal children. Conclusions: Our findings suggest that the neurochemical profile of the occipital cortex is partially affected byidiopathic IN, but not by bilateral ametropic amblyopia.
