The Fatigue Impact Scale for Daily Use (D-FIS) was used in a cross-sectional study including 142 consecutive Parkinson's disease (PD) patients. Usual clinical measures for PD, the Montgomery-Asberg Depression Rating Scale and the Parkinson's Disease Questionnaire-8 items were applied. In addition to the D-FIS, patients with fatigue (67.6%, PWF) completed… (More)
BACKGROUND An understanding of the functional aspects of gait and balance has wide ramifications. Individuals with balance disorders often restrict physical activity, travel, and social commitments to avoid falling, and loss of balance confidence, itself, is a source of disability. We studied the functional aspects of gait in patients with essential tremor… (More)
BACKGROUND Patient-centeredness (i.e., providing care that is responsive to individual patient preferences) is increasingly recognized as a crucial element of quality of care. METHODS A six-item patient-centeredness questionnaire was devised to assess the self-perceived needs of essential tremor (ET) patients. A link to the questionnaire was included in… (More)
BACKGROUND Patients with essential tremor (ET) who develop Parkinson's disease (PD) (i.e., ET→PD) may differ with respect to motor features (MFs) and non-motor features (NMFs) from patients with isolated ET. Few studies have assessed this issue. METHODS In this retrospective chart review, we analyzed data on MFs and NMFs of 175 patients, including 54… (More)
BACKGROUND Jaw tremors in essential tremor (ET) rarely represent anything other than a cosmetic concern. PHENOMENOLOGY SHOWN A case of an ET patient whose jaw tremor was severe enough to result in cracked teeth. EDUCATIONAL VALUE It behooves treating clinicians to be aware of the full spectrum of this movement disorder.
We describe a novel technique for identification of cortical centres that have electrical activity coupled to the activity of skeletal muscles in pathological tremor. This technique utilises concurrent recordings of high-density surface electromyograms (EMG) and electro-encephalograms (EEG). First, the discharge patterns of individual motor units are… (More)
