Forward head and rounded shoulder posture (FHRSP) is theorized to contribute to alterations in scapular kinematics and muscle activity leading to the development of shoulder pain. However, reported differences in scapular kinematics and muscle activity in those with forward head and rounded shoulder posture are confounded by the presence of shoulder pain. Therefore, the purpose of this study wa...

PURPOSE To evaluate early functional outcomes of hemiarthroplasty for 3- or 4-part proximal humeral fractures. METHODS 16 men and 11 women aged 27 to 83 (mean, 56) years underwent hemiarthroplasty for comminuted 3-part (n=13) or 4-part (n=14) proximal humeral fractures. All the patients reported normal shoulder function prior to injury. The range of shoulder motion and muscle power were evalu...

The purpose of this study was to clinically examine the relationship between rotator cable integrity and the presence of pseudoparalysis. A retrospective review was performed of a consecutive series of arthroscopic repairs of massive rotator cuff tears performed between January 2007 and June 2009. A total of 127 massive tears were identified. Group 1 comprised 24 patients with preoperative pseu...

Reverse shoulder arthroplasty may be performed using components that medialize or lateralize the center of rotation. The purpose of this prospective study was to directly compare 2 reverse shoulder arthroplasty designs. Two treatment groups and 1 control group were identified. Group I comprised 9 patients using a medialized Grammont-style (GRM) prosthesis with a neck-shaft angle of 155°. Group ...

OBJECTIVE Post-stroke shoulder pain is a common phenomenon in hemiplegia and impedes rehabilitation. The aim of this study was to identify a possible relationship between post-stroke shoulder pain, scapula resting position and shoulder motion. METHODS Shoulder kinematics of 27 patients after stroke (17 men) were compared with 10 healthy age-matched control subjects. Using an electromagnetic t...

BACKGROUND In the absence of scientific evidence regarding the effectiveness of shoulder management strategies after stage I of fingertip reconstruction, the purpose of this study was to compare the clinical outcomes of various rehabilitation procedures. MATERIAL AND METHODS Patients who underwent fingertip reconstruction with a random-pattern abdominal skin flap between March 2007 and Februa...

BACKGROUND As shoulder arthroplasty becomes more common, the number of failed arthroplasties requiring revision is expected to increase. When revision arthroplasty is not feasible, resection arthroplasty has been used in an attempt to restore function and relieve pain. Although outcomes data for resection arthroplasty exist, studies comparing the outcomes after the removal of different primary ...

BACKGROUND AND PURPOSE The purpose of this study was to assess the association between innominate torsion (asymmetric anteroposterior positioning of the pelvic innominates) and Gillet, standing forward flexion, sitting forward flexion, and supine-to-sit tests. SUBJECTS A sample of 21- to 50-year-old patients with low back pain (n=150) and a comparison group of patients with upper-extremity im...

The aim of this study was to discover finger interaction indices during single-finger ramp tasks and multi-finger coordination during a steady state force production in two directions, flexion, and extension. Furthermore, the indices of anticipatory adjustment of elemental variables (i.e., finger forces) prior to a quick pulse force production were quantified. It is currently unknown whether th...
