Physical activity level and sedentary behavior in patients with bronchiectasis: A systematic review of outcome measures and determinants.

BACKGROUND: Changes in respiratory functions negatively affect the physical activity (PA) levels of patients with bronchiectasis. Therefore, detecting the most frequently used assessments of PA is essential as determining related factors and improving PA. This review study aimed to investigate the PA levels, compare levels with the recommended PA guidelines, determine the outcome measurements of PA and examine the determinants related to PA in patients with bronchiectasis. METHOD: This review was conducted using databases of MEDLINE, Web of Science, and PEDro. The searched terms were the variations of the words "bronchiectasis" and "physical activity". Full texts of cross-sectional studies and clinical trials were included. Two authors independently screened the studies for inclusion. RESULT: The initial search identified 494 studies. A hundred articles were selected for full-text review. Following the application of the eligibility process, 15 articles were included. Twelve studies used activity monitors and five studies used questionnaires. The studies that used activity monitors presented daily step counts. The mean number of steps ranged between 4657 and 9164 for adult patients. It was approximately 5350 steps/day in older patients. One study investigated children's PA level reported 8229 steps/day. The functional exercise capacity, dyspnea, FEV1 and, quality of life as related determinants with PA have been reported in the studies. CONCLUSION: PA levels of patients with non-cystic fibrosis bronchiectasis were lower than the recommended levels. The objective measurements were frequently used in PA assessment. In further studies, it is needed to investigate the related determinants of PA in patients.

Effectiveness of Exercises With Electromyographic Biofeedback in Conservative Treatment of Massive Rotator Cuff Tears: A Randomized Controlled Study.

OBJECTIVE: The aim of the study is to investigate the effectiveness of a rehabilitation program with electromyographic biofeedback compared with the control group on patients with massive rotator cuff tear. DESIGN: Forty-six adults with massive rotator cuff tears, randomly assigned to 2 groups (23 electromyographic biofeedback group vs. 23 control group). The electromyographic biofeedback group (experimental group) performed the exercises under the guidance of electromyographic biofeedback, unlike the control group. All patients underwent a 45-minute training session a day, 3 times a week over a 6-wk duration, and followed up until 1-year. The outcome measures were American Shoulder and Elbow score, shoulder flexion strength, shoulder range of motion, Numeric Pain Rating Scale, and Global Rating of Change Scale. RESULTS: Compared with the control group, the electromyographic biofeedback group demonstrated a significant change in shoulder flexion strength and patient satisfaction from baseline to 6 wks (posttraining) and from baseline to 12-mo follow-up ( F = 4.671, P = 0.005). There were significant improvements in within groups statistics for American Shoulder and Elbow score, shoulder flexion strength, shoulder range of motion, and Numeric Pain Rating Scale in both groups ( P < 0.05). CONCLUSIONS: The results demonstrate that deltoid-focused structured rehabilitation program combined with electromyographic biofeedback can be used to increase shoulder flexion strength and patient satisfaction in conservative treatment of massive rotator cuff tear.
