Balo's concentric multiple scleroses (MS) is a rare demyelinating disease and a variant of multiple sclerosis. We report a case with interesting misleading clinical history and typical RI findings of Balo disease. A 19-year-old girl presented with fever and left hemiparesis following dental procedure 15 days ago. On physical examination fever and left limbs forces loss were noted. On CT scan a ...

THE AIM OF THE INVESTIGATION WAS TO 1) compare shoulder external/internal rotator muscles' peak torques and average power values and their ratios in the dominant and non-dominant arm; 2) determine correlations between shoulder rotator muscles' peak torques, average power and ball-throwing speed in handball players. Fourteen 14 to 15-year-old male athletes with injury-free shoulders participated...

This study examined the influence of the elongation of attached crossbridges and residual force enhancement on joint torque enhancement by the stretch-shortening cycle (SSC). Electrically evoked submaximal tetanic plantar flexions were adopted. Concentric contractions were evoked in the following three conditions: after 2 s isometric preactivation (ISO condition), after 1 s isometric then 1 s e...

The effects of concentric contractions and passive stretching on musculotendinous stiffness and muscle activity were studied in 18 healthy human volunteers. Passive and concentric plantar flexor joint moment data were recorded on an isokinetic dynamometer with simultaneous electromyogram (EMG) monitoring of the triceps surae, real-time motion analysis of the lower leg, and ultrasound imaging of...

BACKGROUND The literature reports that the eccentric muscular action produces greater force and lower myoelectric activity than the concentric muscular action, while the heart rate (HR) responses are bigger during concentric contraction. OBJECTIVES To investigate the maximum average torque (MAT), surface electromyographic (SEMG) and the heart rate (HR) responses during different types of musc...

BMJ Case Reports Published online: [please include Day Month Year] doi:10.1136/ bcr-2012-008413 DESCRIPTION In January 2012 a 51-year-old woman was admitted to our department for a slow increasing right hemiparesis with right brisk deep tendon reflexes. She suffered from Sjogren syndrome, fibromyalgia and hepatitis B virus (healthy carrier). Conv...

To investigate how mild symptomatic patellar tendinopathy (PT) affects quadriceps contractions and the Fente motion, this case-control study examined elite fencers who continue to train and play fully with mild tendon pains. Twenty-four elite fencers (10 women) with mild symptomatic PT and 24 controls (10 women) participated in the study. Concentric/eccentric isokinetic strength of the quadrice...
