The purpose of this study was to compare shoulder range-of-motion (ROM) and strength values between bodybuilders and nonbodybuilders. Fifty-four men (29 bodybuilders and 25 nonbodybuilders) between the ages of 21 and 34 years participated in the study. Goniometric measurements were used to assess shoulder flexion and internal and external rotation ROM. Isometric manual muscle tests were perform...

[Purpose] The purpose of this study was to compare the reliability of the measurement of the passive range of motion (PROM) of shoulder horizontal adduction (SHA) measurements using a smartphone for the assessment posterior shoulder tightness (PST) between the side-lying and supine test positions. [Subjects and Methods] Forty-seven subjects (mean ± age, 24.9 ± 3.5 years) without shoulder pathol...

The purpose of this study was to examine the relationship between dynamic hip rotational range of motion and upper extremity kinematics during baseball pitching. Thirty-one youth baseball pitchers (10.87 ± 0.92 years; 150.03 ± 5.48 cm; 44.83 ± 8.04 kg) participated. A strong correlation was found between stance hip rotation and scapular upward rotation at maximum shoulder external rotation (r =...

BACKGROUND Glenohumeral internal rotation deficit (GIRD) and posterior shoulder tightness have been linked to internal impingement. PURPOSE To determine if improvements in GIRD and/or decreased posterior shoulder tightness are associated with a resolution of symptoms. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Passive internal rotation and external rotation (ER) range of mot...

OBJECTIVE To assess the relationship between shoulder mobility and strength and the presence of pain among baseball players. METHODS Between April and July 2009, 55 baseball players were assessed by the Shoulder and Elbow Group of the School of Medical Sciences, Santa Casa de Misericórdia, São Paulo. They were all males, aged between 15 and 33 years (mean of 21); they attended an average of t...

BACKGROUND Patients with frozen shoulder who fail conservative therapy need surgical treatment and aggressive post-operative rehabilitation. OBJECTIVE To evaluate the effect of continuous cervical epidural analgesia on pain scores and range of motion of the shoulder joint in patients undergoing surgery for treatment of refractory frozen shoulder. METHODS Twenty-one patients with refractory ...

CONTEXT The overhead throwing motion is complex, and restrictions in range of motion (ROM) at the hip may place additional demands on the shoulder that lead to injury. However, the relationship between hip and shoulder ROM in athletes with and without a history of shoulder injury is unknown. OBJECTIVE To (1) determine if differences exist in hip and shoulder ROM between professional baseball ...

The shoulder joint is the foundation for excellent upper extremity function. It contributes to stability and basic movements like rotation and elevation of the arm. Shoulder fusion should not be accepted even for total palsy, and nerve repair should be recommended as long as an available donor nerve exists. In planning the reconstructive procedure for shoulder function, accurate biomechanical a...

OBJECTIVE To determine variables among glenohumeral elevation and 3-dimensional scapular rotations that are related to shoulder function as assessed by the Disability of the Arm, Shoulder and Hand-Disability/Symptom (DASH-D/S) scale. DESIGN Prospective, cross-sectional study. PATIENTS Eighty-eight patients with shoulder pain and limited range of motion were included. METHODS Each patient ...
