BACKGROUND Parkinson's disease (PD) affects 1-2% of the population over 65 years. There is evidence that the clinical features differ with age at symptom onset, but published information is scarce. METHODS We reviewed the charts of 593 PD patients and divided them into young onset (≤49 years), middle onset (50-69 years) and late onset (≥70 years) groups.(More)
The aim of the investigation was to explore the influence of levodopa therapy on the regularity of the structural variations present in the lower extremity joints of individuals with Parkinson’s disease (PD). Ten participants with PD walked on a treadmill during the states of “off” and “on” levodopa. Approximate entropy was used to quantify the regularity(More)
BACKGROUND PURPOSE Restricture after internal urethrotomy is the major limitation to the long-term success of the procedure. The objective of this study was to evaluate the effect of intraurethral brachytherapy after internal urethrotomy or transurethral scar resection on recurrent urethral stricture. PATIENTS AND METHODS From January 1998 to June 1999,(More)
OBJECTIVES To study the effects of levodopa and walking speed on gait variability in individuals with Parkinson's disease (PD). METHODS Thirty-three individuals with PD were studied. Their mean age was 70.61±9.23 year. The average time since diagnosis was 9.65±5.80 year. Gait variability was studied while 'OFF' and 'ON' dopaminergic medication when the(More)
BACKGROUND For Parkinson's disease (PD) patients, adherence to a regular PD medication schedule is important in achieving optimal symptom control. There are few published studies quantifying PD medication administrations in hospitalized PD patients. METHODS Hospitalization records for 100 veterans with idiopathic PD and admitted to our center were(More)
OBJECTIVE The objective of this study was to investigate the relationships between motor symptoms of Parkinson disease (PD) and activity limitations in persons with PD. DESIGN/METHODS This is a cross-sectional study of persons with mild to moderate PD (N = 90). Associations among axial motor features, limb motor signs, the Physical Activity Scale for the(More)
OBJECTIVE To identify determinants for the use of a walking device in persons with Parkinson's disease (PD). DESIGN Cross-sectional study of participants with PD. SETTING Laboratory. PARTICIPANTS Persons with PD (N=85; 60 men) were studied. Their mean age was 69.4±8.9 years. The average time since diagnosis was 7.9±5.3 years. INTERVENTIONS Not(More)
BACKGROUND AND AIMS There is a paucity of information on cardiovascular responses with regard to the disease stage of Parkinson's disease (PD) when using an exercise test. Our purpose was to examine whether cardiovascular responses to the treadmill exercise test differed among persons with PD who have different disease severity. METHODS Forty-five(More)
Results: Chart review identified 17 patients. The most common symptom at diagnosis was tinnitus, followed by sensorineural hearing loss, vertigo, facial pain, and headache. Physical exam revealed facial hypesthesias in 3 patients, facial paresis in 2 patients, while 14 patients had no physical exam findings on presentation. MRI studies of all patients(More)
