Despite its importance for the understanding of joint mechanics in healthy subjects and patients, there has been no three-dimensional (3D) in vivo data on the translation of the humeral head relative to the glenoid during abduction under controlled mechanical loading. The objective was therefore to analyze humeral head translation during passive and active elevation by applying an open MR techn...

Generalized shoulder pain is a common problem that is difficult to treat and frequently recurrent. The asymptomatic cervical spine must be ruled out as a cause of any shoulder pain, as it can have a similar presentation to an isolated shoulder disorder. Previous studies have shown that lateral cervical glide mobilizations to the asymptomatic cervical spine at C5/6 can affect peripheral pain, bu...

BACKGROUND Changes to the integrity of the acromioclavicular (AC) joint impact scapulothoracic and clavicular kinematics. AC ligaments provide anterior-posterior stability, while the coracoclavicular (CC) ligaments provide superior-inferior stability and a restraint to scapular internal rotation. The purpose of this cadaveric study was to describe the effect of sequential AC and CC sectioning o...

BACKGROUND Purpose of this study was to evaluate the functional outcome of spinal accessory to suprascapular nerve transfer (XI-SSN) done for restoration of shoulder function and partial transfer of ulnar nerve to the motor branch to the biceps muscle for the recovery of elbow flexion (Oberlin transfer). METHODS This is a prospective study involving 15 consecutive cases of upper plexus injury...

This study investigates the altered thoracohumeral kinematics when forearm rotation is restricted while performing five activities requiring pronation and supination. Two splints simulated both a fixed-supinated or fixed-neutral forearm in six healthy subjects; the three-dimensional coupled relationship among motion about the forearm, elbow, and shoulder were analyzed. In using a screwdriver, t...

Introduction Nowadays, the current understanding is that the shoulder impingement syndrome (SIS) is characterized by impairment and dysfunction of several structures, contained in the subacromial space, which alter normal shoulder movements of flexion and abduction and provoke pain. Currently, the SIS is a clinical diagnosis based on the patient’s history and physical findings which occurs at a...

AIMS The aim of our study was to compare the effects of suprascapular nerve block in patients with frozen shoulder and diabetes mellitus unresponsive to intraarticular steroid injections. SETTINGS AND DESIGN Ten patients without improvement of sign and symptoms after intraarticular injections were made a suprascapular nerve block. METHODS Pain levels and active range of movement of patients...

Objective To evaluate the effect of acupuncture on rehabilitation of motor function, reduction in lymphoedema and improvement in perceived heaviness and tightness in the arms of women who had undergone breast cancer surgery. Subjects and Methods Twenty nine women who had had mastectomy or segmentectomy with axillary dissection, presenting with lymphoedema and/or a decrease in movement amplitude...

PURPOSE The purpose of this study was to examine the results of arthroscopic debridement for isolated degenerative joint disease of the shoulder. METHODS We retrospectively identified 81 patients who had arthroscopic debridement to treat glenohumeral arthritis. Of these patients, 71 (88%) were available for follow-up. The preoperative Simple Shoulder Test score, American Shoulder and Elbow Su...

[Purpose] The purpose of this study was to compare the potential effects of resistance exercise according to the positions of the arms and the rotation of the humerus on the subhumeral acromial space. [Subjects] The study subjects were 34 subjects without shoulder pain. [Methods] Ultrasonographic measurements of the acromiohumeral distance of the subjects were made at three shoulder positions: ...
