OBJECTIVES Gait and cognitive disorders are frequently reported in patients with multiple sclerosis, leading to decreased quality of live. The objective of this prospective study was to examine the impact of four specific cognitive tasks on gait in patients with relapsing-remitting multiple sclerosis (RRMS) with low disability. METHODS The mean±standard(More)
Gait disturbances found in patients with idiopathic normal pressure hydrocephalus (iNPH) are unspecific to the diagnosis and commonly occur in neurodegenerative or vascular conditions (iNPH-like conditions). This current retrospective pre-post intervention study aims to determine whether changes in quantitative gait parameters during dual task condition(More)
BACKGROUND   Gait disorders in patients with idiopathic normal pressure hydrocephalus (iNPH) share similar characteristics found in pathologies presenting with higher-level gait disorders that have been specifically associated with gait changes during walking while simultaneously performing an attention-demanding task (i.e. dual tasking). The current study(More)
Signature identification and verification has been a topic of interest and importance for many years in the area of biometrics. In this paper we present an effective method to perform off-line signature verification and identification. To commence the process, the signature's contour is first determined from its binary representation. Unique structural(More)
BACKGROUND/AIMS To measure the Timed Up and Go (TUG), imagined TUG (iTUG), and the difference of time between these two tests (delta time) in 20 patients with relapsing-remitting multiple sclerosis (RRMS) and 20 healthy age-matched controls and to examine whether an association with cognitive functions, motor impairment, and behavioral changes can be(More)
BACKGROUND Gait impairment is common in parkinsonian syndromes but not specific to striatonigral dysfunction. The relationship between the dopaminergic system and gait parameters is poorly understood. This cross-sectional study aimed to determine if gait measures are related to the striatal dopamine transporters distribution using [(123)I]FP-CIT SPECT in(More)
