During use of the normal shoulder, the humeral head is centered within the glenoid and the coracoacromial arch. When the shoulder cannot maintain this centered position during use, it is unstable. An unstable shoulder prevents normal function of the upper extremity. Shoulder instability is not the same as joint laxity. Joint laxity is a property of normal joints and allows the shoulder to attai...

[Purpose] This study investigated the effects of an end-range mobilization technique on the range of motion of the glenohumeral internal rotation and the skin temperature of the shoulder in individuals with posterior shoulder tightness. [Subjects] Thirteen subjects with posterior shoulder tightness who had glenohumeral internal rotation deficit ≥ 15° participated. [Methods] All subjects underwe...

We examined proprioceptive differences between the dominant and nondominant shoulders of 21 collegiate baseball pitchers without a history of shoulder instability or surgery. A proprioceptive testing device was used to measure kinesthesia and joint position sense. Joint position sense was significantly (P =.05) more accurate in the nondominant shoulder than in the dominant shoulder when startin...

A 54-year-old female presented with intermittent pain over right shoulder off and on for 1 month. She did not recall any associated major trauma, but she was a retired teacher who frequently needed raising right shoulder for writing on blackboard. Physical examinations only showed a swelling mass about 2 × 1 cm with mild tenderness over right shoulder joint and mild limited of range of motion. ...

OBJECTIVE To evaluate the functional outcomes of patients submitted to arthroscopic repair of triple labral lesion. METHODS This was an analytical retrospective study of patients who underwent arthroscopic treatment of triple labral lesion from March 2005 to December 2014. Patients with at least one year of postoperative follow-up were included. A total of nine patients were evaluated. The me...

Everyday actions invariably consist of a combination of discrete and rhythmic elements within or across joints. The study investigated constraints arising from the co-occurrence of the two actions in a two-joint task and how endpoint trajectories are shaped due to these action elements at the joint level. The task consisted of an elbow oscillation in the plane that was to be merged with a fast ...

This study was conducted to examine the influence of combined exercise using proprioceptive neuromuscular facilitation (PNF) and deep breathing exercise on range of motion (ROM) and visual analog scale (VAS) score in acute frozen shoulder patient. The subject of this study was woman complained disabilities in daily routine due as a frozen left shoulder. The exercise program was composed of 11 s...

 Abstract Two cases (20 and 15 years old) of shoulder joint synovial chondromatosis were initially treated with arthroscopic debridement. One was further treated with a second arthroscopy and partial synovectomy (case 1) the second was fully treated by arthroscopic surgery (case 2). The postoperative control X- ray revealed no loose body and the joint was normal. One of the cases (case 1) was a...

Background. The shoulder joint has a very complex structure. Normal shoulder function is dependent on joint stability and proper neuromuscular control. Given its anatomical structure and range of movement, this joint is highly susceptible to numerous disorders and injuries. Normal stability of the shoulder guarantees physiological function, and is also the most important element of injury preve...

conclusions bilateral anterior shoulder dislocation is rare. it could be undiagnosed, especially when there is no clear history of major trauma. by awareness of such unusual possibility, early diagnosis, treatment, and reduction can provide desirable outcome. introduction shoulder dislocation is the most common presentation of joint dislocation in emergency department (ed). bilateral shoulder d...
