BACKGROUND There are a number of indications for total joint replacement surgery, mainly degenerative changes with limited function, rheumatoid arthritis, post-traumatic changes, arthropathy accompanying rotator cuff injuries. Problems in the rehabilitation of patients following partial or total shoulder joint replacement surgery result from the anatomy and biomechanics of the shoulder, includi...

Infection around the shoulder joint is rare. Clinical suspicion and diagnostic imaging are required for accurate diagnosis. We present three cases that emphasise particular diagnostic challenges when dealing with infection around the shoulder joint. Discussion includes the role of ultrasound as a screening tool and the importance of magnetic resonance imaging (MRI) in the accurate diagnosis and...

OBJECTIVES To evaluate the impact of two different modes of shoulder injection training on the level of confidence and number of injections performed by general practitioners (GPs) METHODS Demographic details, and information on referrals for shoulder problems, shoulder joint injection activity, and confidence in the six months before training were obtained for 40 GP principals at baseline. S...

BACKGROUND Many prior studies have evaluated shoulder motion, yet no three-dimensional analysis comparing the combined clavicular, scapular, and humeral motion during arm elevation has been done. We aimed to describe and compare dynamic three-dimensional motion of the shoulder complex during raising and lowering the arm across three distinct elevation planes (flexion, scapular plane abduction, ...

OBJECTIVE This study aimed at comparing the effect of linear polarized near-infrared light irradiation (PL irradiation) and bicycle exercise with 50%HRreserve on the flexibility of the shoulder joint. DESIGN Placebo-controlled trial. SETTING Twenty-four healthy young adults (10 males: mean+/-SD, age 20.9+/-3.1 y, height 171.0+/-3.9 cm, body mass 63.4+/-3.5 kg and 14 females: age 21.2+/-1.7 ...

[Purpose] This study investigated the effects of stretching and joint stabilization exercises applied to spastic shoulder joints on improving shoulder dysfunction in hemiplegic patients. [Subjects and Methods] Hemiplegic patients were classified into three groups: one group received 30 min of traditional exercise therapy for the spastic shoulder joint; one group received 30 min stretching; and ...

The present study addressed the effect of articular conformity of the shoulder joint on the stability of inter-joint coordination during circular drawing movements. Twelve right-handed participants performed clockwise and counter-clockwise circular drawing movements at nine locations in the mid-sagittal plane. The task was paced acoustically at 1.0, 1.5 and 2.0 Hz and performed without visual c...

BACKGROUND Altered neuromuscular control due to compromised joint position sense may contribute to recurrent shoulder instability. OBJECTIVE The purpose of the present study was to examine whether individuals with anterior shoulder instability exhibit larger shoulder position sense errors than those with healthy shoulders in both passive matching and active positioning. DESIGN This was a be...

introduction: the shoulder is one of the most vulnerable joints for handball players.  frequent throwing movements can change its muscular strength balance and range of motion. however, the balance of strength and range of motion are important factors in injury prevention. the purpose of this study was to compare the internal-to-external ratios of strength rotation and rom rotation in the domin...

The shoulder (glenohumeral) joint has the greatest range of motion of all human joints; as a result, it is particularly vulnerable to dislocation and injury. The ability to accurately measure dynamic in-vivo joint kinematics in 6-Degrees-of-Freedom (6-DOF) (translations and rotations) and subsequently quantify articular cartilage contact patterns of that joint has been and remains a difficult b...
