Teacher: Given an abstract of a paper, generate a title for this paper such that conveys the key focus of the paper.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available.
Solution: Refibrillation managed by EMT-Ds
Reason: The abstract is about refibrillation and it is also mentioned in the abstract that it is managed by EMT-Ds. So it is an apt title.

The shoulder mechanism provides the upper limb with a range of motion exceeding that of any other joint mechanism. The placement of the hand is determined by four components of the shoulder complex: the glenohumeral, acromioclavicular, and sternoclavicular joints and the scapulothoracic gliding mechanism. The clavicular joints permit the scapula to move against the chest wall during movements of the arm, allowing the glenoid fossa to follow the head of the humerus, and thus contribute significantly to total arm movement. The functional interrelationships between the glenohumeral, scapulothoracic, and clavicular joint mechanisms are critical in providing a full, functional ROM. Any pathological condition of any one of these mechanisms will disturb upper limb function. The ligamentous and periarticular structures of the shoulder complex combine in maintaining the joint relationships, withstanding the forces applied to the joint surfaces, and stabilizing the dependent limb.
