The organization of spinal cord motor columns innervating 18 selected macaque forelimb muscles was studied with the technique of retrograde transport of horseradish peroxidase. The reliability of the method was evaluated in the cat hindlimb. Motor columns innervating forearm muscles with similar actions on the hand appear to overlap in the anterior horn. Extensor motoneurons are generally posit...

BACKGROUND The study objective was to assess the influence of a SLAP lesion on onset of EMG activity in shoulder muscles during a front on rugby football tackle within professional rugby players. METHODS Mixed cross-sectional study evaluating between and within group differences in EMG onset times. Testing was carried out within the physiotherapy department of a university sports medicine cli...

Pain following thoracotomy is of moderate to severe nature. Management of thoracotomy pain is a challenging task. Post thoracotomy pain has acute effects in the post operative period by affecting respiratory mechanics, which increases the morbidity. Poorly controlled thoracotomy pain in the acute phase may also lead to the development of a chronic pain syndrome. A young male patient underwent e...

OBJECTIVES Pushing tasks are functional activities of daily living. However, shoulder complaints exist among workers exposed to regular pushing conditions. It is crucial to investigate the control of shoulder girdles during pushing tasks. The objective of the study was to demonstrate scapular muscle activities and motions on the dominant side during pushing tasks and the relationship between sc...

Our purpose in this study was to develop a functional form of radiography and to perform a quantitative analysis for the shoulder joint using a dynamic flat panel detector (FPD) system. We obtained dynamic images at a rate of 3.75 frames per second (fps) using an FPD system. Three patients and 5 healthy controls were studied with a clinically established frontal projection, with abduction of th...

BACKGROUND Usually, several surgical methods are used, with re-suturing, free skin grafting and local flaps, for the reconstruction of wall defects after abdominoperineal resection. However, or larger defects, free flaps have been preferred because they can provide a large area of well-vascularized soft tissue, which is suitable for defect repair. We present the case of a large abdominal wall d...

A lthough the internal mammary vessels remain the recipient vessels of choice in free flap breast reconstruction, the thoracodorsal vessels are still chosen for a variety of reasons. The use of the internal mammary artery as a recipient vessel is justified despite concern for future coronary revascularization. 1 The thoracodorsal vessels continue to be used because of surgeon preference and cas...

The purpose of this study was to observe changes in electromyographic activity appeared in shoulder and scapular muscles when one wears no wrist extension orthosis, short wrist extension orthosis and long wrist extension orthosis when performing two model assembling operations. The study subjects were 16 adults who use right hand and did not have any functional disorder on their wrist or the up...

The H-reflex response in large and small single motor units in human deep anterior masseter was studied to investigate the distribution of muscle spindle afferents onto masseter motoneurons. We found that only the larger units displayed H-reflex responses. This indicates preferential distribution of muscle spindle input onto large motoneurons or a skewed distribution of tonic presynaptic inhibi...
