Parkinson’s disease (PD) is a neurodegenerative disorder and patients suffering from PD experience a variety of biomechanical symptoms including tremors, stooping, rigidity, and gait instability. PD is also characterized by a permanent increase in response time in both voluntary and involuntary motor responses. Although the deterioration in biomechanical control can intuitively be related to sl...

In the paper a detailed analysis of the dynamic response of a cooling tower shell to mining tremors originated from two main regions of mining activity in Poland (Upper Silesian Coal Basin and Legnica-Glogow Copper District) was presented. The representative time histories registered in the both regions were used as ground motion data in calculations of the dynamic response of the structure. It...

To broadly sample ET in different settings, we selected cases from three settings: a tertiaryreferral center (largest sample),5 a population-based study in Manhattan,6 and a brain repository.7 As expected, cases differed in several respects (Table). Using the same clinical questionnaire, each case was asked whether he/she sometimes has a head tremor. A 20 minute videotaped tremor examination wa...

CONTEXT Newborns may present a range of motor phenomena that are not epileptic in nature. Chin tremor is an unusual movement disorder that typically starts in early childhood and may be precipitated by stress and emotion. Its pathophysiology has not been fully elucidated. CASE REPORT We describe a full-term newborn that, immediately after neonatal anoxia, presented body and chin tremors that ...

BACKGROUND In this study, we report a rare case of an adult patient with essential palatal tremors (EPT) presenting as nasal clicks, instead of otic clicks or objective pulsatile tinnitus in common EPT. CASE PRESENTATION Nasal endoscopic examination and EMG recordings of the soft palate muscles were performed to confirm the source of the clicks. Initial treatment with lidocaine provided sympt...

Abstract A location in the Gulf of Guinea, which emits monochromatic seismic waves at 26-second period, seemingly continuously, was identified 1960s. However, origin these remains enigmatic to date. Here we use three-component data from two arrays Africa, as well additional compiled around world, investigate tremors. We identify frequency glides accompanying previously known 26 s microseism sta...
