Frequent use of digital information technology has an impact on eye- and neck/shoulder-discomfort. Studies with cross sectional and intervention design indicate an association between the two symptom categories. Still, whether visually demanding near work, per se, contributes to increased neck/shoulder discomfort remains a question of debate. The aim of this laboratory study was to assess if vi...

Musculoskeletal disorders such as neck pain have been related to computer use in adults and an association between computer use, neck posture and neck pain has been suggested. Computer use in increasing in children and thus the potential for related neck pain and postural changes is increasing. This study evaluated the neck pain, neck posture and computer use of 884 adolescents. Over one third ...

Abstract Running is one of the most popular sports worldwide motivating many non-athletic people to start new physical activities. But especially novice runners are at risk develop injuries as they tend run with prejudicial posture. Hence, there has been considerable research identify factors improving running performance. One these correct movement arms a swinging pendulum during running. Base...

Background and Aim Upper Crossed Syndrome (UCS) is a musculoskeletal disorder leading to postural deformities such as forward head posture (FHP), rounded shoulder (RSP) hyper kyphosis. This abnormality has spread among people in the community due modern lifestyle excessive use of communication technologies. Therefore, aim this study was investigate effect eight -week comprehensive corrective ex...

The present study examined muscular activity in the primate proximal forelimb during a posture task. By applying loads selectively to the shoulder, elbow, or both joints, we observed that monoarticular shoulder and elbow muscles varied their activity with loads at the unspanned joint. Shoulder monoarticulars changed activity with elbow torque and elbow monoarticulars changed activity with shoul...

This study investigated the potential influence of proximal sensory feedback on voluntary distal motor activity in the paretic upper limb of hemiparetic stroke survivors and the potential effect of voluntary distal motor activity on proximal muscle activity. Ten stroke subjects and 10 neurologically intact control subjects performed maximum voluntary isometric flexion and extension, respectivel...

OBJECTIVE To evaluate alterations in posture and range of motion of the upper limbs in women after mastectomy and lymphadenectomy, submitted to radiotherapy as adjuvant treatment. METHODS Two groups were evaluated: 16 post-mastectomy women with lymphedema of the upper limb and 14 post-mastectomy women without lymphedema. Patients were submitted to analysis made by software, one for posture an...

[Purpose] The purpose of this study was to analyze shoulder stabilization using resistant vibration stimulus during bodyblade exercise followed by forward head posture improvement. [Subjects and Methods] Craniovertebral angle and cranial rotation angle were measured with 24 patients who were diagnosed with forward head posture. The experimental group conducted bodyblade exercise for 6 weeks and...

Forearm support during keyboard use has been reported to reduce neck and shoulder muscle activity and discomfort. However, the effect of forearm support on wrist posture has not been examined. The aim of this study was to examine the effect of 3 different postures during keyboard use: forearm support, wrist support and "floating". The floating posture (no support) was used as the reference cond...

Shoulder pain is one of the most common of all peripheral joint disorders with the point incidence amongst the general population said to be as high as 20% (Pope et al 1997). Often the cause of non-traumatic shoulder pain is thought to be inflammation of the structures around the shoulder due to poor biomechanics with subsequent impingement and inflammation of the affected structures (Bang and ...
