I was delighted to read Burton et al.’s timely paper on work-relevant upper limb disorders and causation, impact and case management in the workplace [1]. Could I make some comments directed primarily at the huge numbers of workers covered by the Display Screen Equipment (DSE) Regulations etc. While I fully endorse the need for a full history and examination (always starting at the neck), in my...

STUDY DESIGN Single-cohort laboratory-based study. OBJECTIVES To measure thoracic spine extension motion during bilateral arm elevation using functional radiography and photographic image analysis. BACKGROUND Impairment of thoracic spine extension motion may impact shoulder girdle function. Motion of the thoracic spine during arm movement has not been directly measured using functional radi...

Conservative treatment of thoracic outlet syndrome consists initially of pain control and medicinal and physical measures. Therapy then addresses tight muscles, with strengthening of weakened neck and shoulder girdle muscles. Range of motion and nerve gliding exercises are instituted simultaneously, and the patient is educated in proper posture and ergonomics at home and in the work setting.

We studied the discharge of neurons from both the superior colliculus (SC) and the underlying mesencephalic reticular formation (MRF) and its relation to the simultaneously recorded activity of 11 arm muscles. The 242 neurons tested with a center-out reach task yielded 2,586 pairs of neuron/muscle cross-correlations (normalized, such that perfect correlations are +/-1.0). Of these, 43% had peak...

BACKGROUND Dysfunction of the cervicothoracic spine and the adjacent ribs (also called the shoulder girdle) is considered to predict occurrence and poor outcome of shoulder symptoms. It can be treated with manipulative therapy, but scientific evidence for the effectiveness of such therapy is lacking. OBJECTIVE To study the effectiveness of manipulative therapy for the shoulder girdle in addit...

The turtle shell and the relationship of the shoulder girdle inside or 'deep' to the ribcage have puzzled neontologists and developmental biologists for more than a century. Recent developmental and fossil data indicate that the shoulder girdle indeed lies inside the shell, but anterior to the ribcage. Developmental biologists compare this orientation to that found in the model organisms mice a...

In the study maintenance workers were involved in pneumatic wrenching, oxy-gas cutting, and grinding at 5 different heights. Working posture and workers' perceptions were measured. Guidelines on working height were formulated in order to minimize the load on the musculoskeletal system. Data from the present experiment as well as from literature were studied in depth in order to disclose generic...

Congenital absence of shoulder girdle muscles is described in three generations of a family. The proband, a 3 year old boy, had absence of the sternocostal head of the right pectoralis major. His father had absence of the left serratus anterior and part of the left latissimus dorsi and his paternal grandfather had absence of the lower two-thirds of the left pectoralis major, with absence of the...

INTRODUCTION The performance ofan elite archer can be affected by effective control of muscle in the upper extremities. Moreover, archery can be described as a comparatively static sport requiring strength and endurance of the upper body, in particular of the forearm and shoulder girdle [1]. Thus, EMG provides useful information to investigate the static skill sof archery. So far, a contraction...
