Abstract Introduction The objective of this study is to perform an initial evaluation a system for assessment and visual feedback the surgeon's posture during laparoscopic practice. Methods In order monitor posture, we used XSens motion tracking system. neck, shoulder, elbow, wrist joints were analyzed A method was designed using Unity3D which indicates in real time if any suffers from inadequa...

Although it is commonly accepted that there is an interrelationship between the temporomandibular joint (TMJ) and head posture, few, if any, previous studies have quantified this effect. The purpose of this study is to quantify the effect of a change in the condyle fossa relationship of symptomatic temporomandibular joints on head posture. Charts of 51 patients (N=10 men and N=41 women) with sy...

The present study investigated the existence of a relationship between depression and body posture in 40 women, aged between 20 and 30 years, who had normal body mass indices (or were underweight) and absence of neurological, psychiatric, or musculoskeletal disorders. The aim of the present study was to investigate the existence of a relationship between sadness, depression and the posture repr...

Each year, 17.9% of adults working in a computer-dominated work environment develop an episode of chronic neck and shoulder pain. An effective treatment method for chronic pain is postural correction through therapist. The understanding of the relation between cervicoscapular posture and trapezius muscle activity is not fully understood because the anatomy of the scapula is not accessible for d...

A 54-year-old female presented with intermittent pain over right shoulder off and on for 1 month. She did not recall any associated major trauma, but she was a retired teacher who frequently needed raising right shoulder for writing on blackboard. Physical examinations only showed a swelling mass about 2 × 1 cm with mild tenderness over right shoulder joint and mild limited of range of motion. ...

Wearable technologies for posture monitoring and posture correction are emerging as a way to support and enhance physical therapy treatment, e.g., for motor control training in neurological disorders or for treating musculoskeletal disorders, such as shoulder, neck, or lower back pain. Among the various technological options for posture monitoring, wearable systems offer potential advantages re...

Biceps brachii motor evoked potentials (MEPs) from cortical stimulation are influenced by arm posture. We used subcortical stimulation of corticospinal axons to determine whether this postural effect is spinal in origin. While seated at rest, 12 subjects assumed several static arm postures, which varied in upper-arm (shoulder flexed, shoulder abducted, arm hanging to side) and forearm orientati...

Loading/unloading a ladder on vehicles are frequent tasks and involve overhead handling that may expose workers to risk factors of shoulder musculoskeletal disorders. The objective of the present study was to evaluate posture, forces required and perceived exertion when loading and unloading the ladder on a utility truck. Thirteen male overhead line workers from an electric utility in Brazil pa...
