Rotator cuff refers to the group of muscles and tendons that connect the upper arm to the scapula or shoulder blade. The tendons of the rotator cuff help in providing stability to the shoulder and the muscles help in rotation of shoulder. There are four types of muscles present in the rotator cuff-teres minor, supraspinatus, subscapularis and infraspinatus. Teres minor muscle helps in outward movement of arm, supraspinatus muscles helps in moving the arm away from body, subscapularis helps in inward movement of arm and infraspinatus muscle help in lifting of arm when the arm is moved outward. If there is tearing of any one of the four muscles then rotator cuff tear. Any damage to the rotator cuff causes rotator cuff disease.
The damage can occur to the rotator cuff due to some inflammation caused by arthritis or tendinitis or because of ageing. The symptoms of rotator cuff disease include shoulder pain which at acute level can cause frozen shoulder. The person having rotator cuff disease finds it difficult to lift the arm. The disease can be diagnosed either by X-ray or radiology testing.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
