The purpose of the study was to investigate whether individuals with anterior glenohumeral joint (GHJ) instability exhibit different scapular orientation from individuals with healthy shoulders in a planar shoulder movement and a functional three-dimensional (3D) reaching task. ⋯ Results of this study show that scapular orientation changes associated with shoulder abduction and functional reaching activities were similar in people with GHJ instability and those with healthy shoulders. The current study suggests that anterior GHJ instability has little impact on scapular kinematics during upper limb movements in a chronic condition without pain, muscle weakness or limited range of motion. Altered scapular kinematics may not contribute to the high recurrence rate of anterior GHJ dislocation.

Comparative Study Observational Study
Respiratory muscle strength, the six-minute walk test and quality of life in Chagas cardiomyopathy.
Patients with heart failure disease develop respiratory and functional limitations and suffer from the negative influence on their quality of life. This study was designed to evaluate respiratory muscle strength and its relationship to functional capacity, quality of life and rate of perceived exertion in patients with Chagas cardiomyopathy. ⋯ The inspiratory muscle strength is reduced, and the decreased quality of life has a negative influence on the physical and emotional aspects of the patients with Chagas cardiomyopathy. No correlation was found between perceived exertion and the reduction of respiratory muscle strength.
