A patient affected by low-frequency postural tremor of the trunk and limbs is reported. Apart from mild dysarthria and gait ataxia, no other neurological abnormalities were present. Cerebellar atrophy was demonstrated by means of magnetic resonance imaging. The tremor was associated with alternating activity in antagonistic muscles; it was triggered whenever a contraction of lumbar back extenso...

The effect of dietary administration of clenbuterol on soleus and extensor digitorum longus muscles was studied after 4 and 21 days. Both muscles showed an increase in wet weight with no significant change in total fibre number. After 4 days fibre cross-sectional areas were increased in soleus, but not in extensor digitorum longus, and after 21 days there was a change in fibre frequencies in ex...

The extensor indicis is a narrow, elongated skeletal muscle in the deep layer of the dorsal forearm that originates from the one third of the distal posterior surface of the shaft of ulna below the origin of the extensor pollicis longos and interosseous membrane. It runs through the fourth tendon compartment with the extensor digitorum under the extensor retinaculum. The extensor indicis joins ...

The presence of additional muscles in the forearm extensor compartment is frequently encountered during surgical procedures and anatomical dissections. There are several types of anomalous muscles such as the extensor indicis proprius, the extensor digitorum brevis manus, the extensor medii proprius, and the extensor indicis et medii communis that have been previously reported in the medical li...

QUESTION Is eight weeks of high-intensity strengthening of the isolated lumbar extensors more effective than low-intensity strengthening or no strengthening? Are any gains maintained 16 weeks later? DESIGN Randomised, three-arm trial with concealed allocation, assessor blinding, and intention-to-treat-analysis. Participants in the waiting list control group were randomised again, after the fi...

STUDY DESIGN Experimental repeated-measures study. OBJECTIVE To investigate the effect of different extension forces applied to the palm of the hand on electromyographic (EMG) activity of the wrist extensor muscles during hand gripping. BACKGROUND Lateral epicondylitis is usually caused by repetitive wrist extension that leads to an overuse injury. The current theory is that the process of ...

Since a Japanese-style bow has a very complicated shape and structure, an archer has to apply the "Teno-uchi" maneuver including horizontally twisting torque, or "Nejiri", and sagittally down-pushing torque, or "Uwa-oshi", to the restoring bow in order to hit the target. The purpose of this study was to investigate the biomechanical relationship between the muscular activities of the left forea...
