Children with axillary burns often develop scar contractures that restrict shoulder movement. Objective data on functional movement patterns after contracture formation is sparse. The purpose of this study was to determine how axillary contractures affect shoulder movement during activities of daily living (ADLs). This was a prospective study of children with axillary contractures scheduled for...

The purpose of this study was to characterize both spatial and temporal patterns of the shoulder joint movement in the upper limb motion when ballet dancers are performing the flaps of swan wings. Twenty-three expert female dancers (Dance group) and 21 inexperienced age-matched females (Control group) participated in the study. Thirty-three reflective markers were attached to the trunk and uppe...

A radiological study of the intraprosthetic movements of a bipolar shoulder replacement was undertaken in 25 shoulders in 20 patients with rheumatoid arthritis and rotator cuff arthropathy. No significant difference was found between intraprosthetic movement and shell - glenoid movement. Some shoulders were found to exhibit paradoxical movement at the intraprosthetic interface. Repeating the me...

BACKGROUND Movement deficits, such as changes in the magnitude of scapulohumeral and scapulathoracic muscle activations or perturbations in the kinematics of the glenohumeral, sternoclavicular and scapulothoracic joints, have been observed in people with shoulder impingement syndrome. Movement training has been suggested as a mean to contribute to the improvement of the motor performance in per...

STUDY DESIGN Cross-sectional. OBJECTIVES To compare sternoclavicular, acromioclavicular, and scapulothoracic joint motion between symptomatic and asymptomatic individuals during shoulder motion performed in 3 planes of humerothoracic elevation. BACKGROUND Differences in scapulothoracic kinematics are associated with shoulder pain. Several studies have measured these differences using surfac...

Upper-arm evaluation including shoulder motion in physiotherapy has no three-dimensional tool for an arm-functioning evaluation, which hampers an uniform, objective comparison. Human shoulder complex models suffer from lack of shoulder girdle kinematic data. A kinematic shoulder-complex model with six degrees of freedom is proposed as the composition of the inner joint representing the shoulder...

During multijoint limb movements such as reaching, rotational forces arise at one joint due to the motions of limb segments about other joints. We report the results of three experiments in which we assessed the extent to which control signals to muscles are adjusted to counteract these "interaction torques." Human subjects performed single- and multijoint pointing movements involving shoulder ...

[Purpose] In sports physical therapy, video of a patient's movement or of a skilled model's movement has been used as observational learning methods for injury prevention and movement modification. Positive effects of model video observation have been reported. This study aimed to clarify the effect on motor skill learning using a combination of model-observation and self-observation, which is ...

Patients: 53 patients 20 to 70 years of age (mean age 54 y, 53% men among 51 patients who completed the trial) who had stage 2 adhesive capsulitis, normal shoulder radiography, passive motion restriction > 30 degrees in ≥ 2 planes of movement, pain for ≥ 1 month, and average daily pain intensity score ≥ 3 out of 10 on a visual analogue scale (VAS) (10 = worst imaginable pain). Exclusion criteri...

BACKGROUND Knowledge about the pattern of rotation during arm elevation is necessary for a full understanding of shoulder function, and it is also useful for planning of rehabilitation protocols to restore range of motion in shoulders in disorder. However, there are insufficient in vivo data available. METHODS; We investigated dynamic arm rotation during elevation in different planes using 30 s...
