background: owing to increased complexity in the evolution of society, stress has become an important public health problem, and is responsible for more than 30 types of diseases. most of the research on stress conducted to date has focused on physical and psychological aspects; however, there are very few reports about the association between psychological stress and elements within the reside...

OBJECTIVE To evaluate the influence of pilot hole tapping on pullout resistance and insertion torque of pedicle screws with a conical core. METHODS Mechanical tests using a universal testing machine were performed on pedicle screws with a conical core that were inserted into pedicles in the fifth lumbar vertebra of calves. The insertion torque was measured using a torque meter with a capacity...

Impaired mobility is a major concern for older adults and has significant consequences. While the widely accepted belief is that improved physical function underlies the effectiveness of targeted exercise training in improving mobility and reducing falls, recent evidence suggests cognitive and neural benefits gained through exercise may also play an important role in promoting mobility. However...

Rhythmic properties of speech and language have been a matter long-standing debates, with both traditional production perception studies delivering controversial findings. The present study examines the possibility investigating linguistic rhythm using movement-based paradigms. Informed by theory methods sensorimotor synchronization, we developed two finger-tapping tasks (synchronization reprod...

BACKGROUND Arrhythmokinesis, the variability in repetitive movements, is a fundamental feature of Parkinson's disease (PD). We hypothesized that unimanual repetitive alternating finger tapping (AFT) would reveal more arrhythmokinesis compared to bimanual single finger alternating hand tapping (SFT), in PD. METHODS The variability of inter-strike interval (CVISI) and of amplitude (CVAMP) durin...

BACKGROUND Hand movement constitutes the most common daily activities in our life. Hand dexterity is often impaired in patients with neurological disease. We developed an adjunct method, based upon the electrodiagnostic software, for study of motor control and hand dexterity. METHODS Thirty-two normal subjects, 2 stroke patients and 2 Parkinson patients were included in the study. All of them...
