Chronic obstructive pulmonary disease (COPD) is a systemic inflammatory disease that can cause repercussions on respiratory muscles and body composition. The aim of the current study was to evaluate inspiratory muscle strength, diaphragmatic mobility, and body composition in COPD subjects and to correlate these variables. ⋯ Our study showed a high prevalence of inspiratory muscle weakness based on the severity of airway obstruction and on the presence of muscular depletion. The evaluation of body composition detected important changes. It also demonstrated that not only muscular weakness was present in these patients but also this had repercussions on the mobility of the diaphragm muscle.

Measurements of joint range of motion (ROM) are part of a physical therapist's daily work. Activities of daily living and exercises can be complicated to perform when ROM is limited, and depending on the demands in daily living, the knee joint requires different ROM. In sports, a few degrees in ROM may make the difference between getting injured or not. The goals for physical therapists are to help the patients to regain full ROM, mobility, strength, and function after sustaining an injury. To measure joints with the manual universal goniometer is considered time-consuming and difficult with respect to repeated measurements. Recently, a new digital instrument for measuring ROM was developed-EasyAngle. A first objective of the study was to investigate the reliability of EA for measuring knee joint angles, considering intrarater and interrater reliability. A second objective was to investigate if there were any differences in the intrarater reliability between a novice and an experienced assessor. ⋯ The results of the present study showed very good ICC values for both intrarater and interrater reliability measuring knee joint ROM with EasyAngle. Relatively high SDD values were seen for both assessors and may indicate a problem monitoring small differences between measurements. Further studies are recommended to increase the generalizability of the results.
