Development and application of a respiratory device on blood pressure in adults with high blood pressure.

Purpose: The purpose of this study is to develop a prototype of a novel respiratory device that we validated and assessed clinically and examined the effect of prototype of respiratory device on blood pressure (BP).

Methods: Prototype of respiratory device (TU-Breath Training) was designed with pressure cuff and application software was created. The immediate effect of resisted breathing was determined in 20 adults with high BP (systolic BP ≥ 130 mmHg and diastolic BP ≥ 90 mmHg).

Positive expiratory pressure breathing speeds recovery of postexercise dyspnea in chronic obstructive pulmonary disease.

Objectives: Faster recovery of postexertional dyspnea might enable chronic obstructive pulmonary disease (COPD) patients to undertake more physical activity. The purpose of this study was to determine whether breathing with a positive expiratory load to reduce dynamic hyperinflation (DH) would hasten recovery.

Methods: Thirteen male COPD patients (59 ± 7 years; Global Initiative for Obstructive Lung Disease Stages II and III) took part in a randomized cross-over trial in which they exercised by self-paced spot marching.

Physical activity and depression in older adults with and without cognitive impairment.

Unlabelled: Low physical activity and depression may be related to cognitive impairment in the elderly.

Objetive: To determine depression and physical activity (PA) among older adults with and without cognitive impairment.

Methods: 156 older adults, both males and females, aged ≥60 years, were asked to complete the Thai Mini-Mental State Examination (Thai-MMSE), a global cognitive impairment screening tool.
