This paper presents an approach for providing realistic force feedback to users manipulating serial-chain virtual mechanisms. In the proposed approach, a haptic device controller is designed that penalizes users’ motion along the directions resisted by the virtual joints. The resisted directions span the null space the Jacobian of the virtual mechanism computed at the users’ hand, and are deriv...

background:purpose of present study was to investigate whether chronic exposure to zinc fume would affect serum zinc levels, memory, and cognition in zinc fume-exposed workers. methods:in a cross-sectional study, all zinc fume-exposed workers (exposed, n=20) were compared with unexposed workers (reference, n=20) matched for sex and education level in a zinc galvanization factory. the workers we...

Javed et al’s guide to the management of elbow pain1 is disappointing on several fronts including its support for the myth that only tennis players get tennis elbow,2 but especially in its description of the clinical signs of this condition and golfer’s elbow. The essence of examining a joint is to distinguish between conditions of the joint proper and those of the muscle and tendons that move ...

The aim of this study was to compare the effects of two different mixed training programs (optimum power load [OPL] + resisted sprints [RS] and OPL + vertical/horizontal plyometrics [PL]) on neuromuscular performance of elite soccer players during a short-term training preseason. Eighteen male professional soccer players took part in this study. The athletes were pair-matched in two training gr...

PURPOSE To evaluate a new clinical test, the resisted supination external rotation test, for the diagnosis of superior labral anterior posterior lesions of the shoulder. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 2. METHODS Forty athletes (average age, 23.9 years) with activity-related shoulder pain were enrolled in the study. The patients underwent 3 different tests designed...
