Effects of treadmill running and fatigue on impact acceleration in distance running

2014

The effects of treadmill running on impact acceleration were examined together with the interaction between running surface and runner's fatigue state. Twenty recreational runners (11 men and 9 women) ran overground and on a treadmill (at 4.0 m/s) before and after a fatigue protocol consisting of a 30-minute run at 85% of individual maximal aerobic speed. Impact accelerations were analysed using two lightweight capacitive uniaxial accelerometers. A two-way repeated-measure analysis of variance showed that, in the pre-fatigue condition, the treadmill running decreased head and tibial peak impact accelerations and impact rates (the rate of change of acceleration), but no significant differenc…

Changes in accommodative responses with multifocal contact lenses: a pilot study.

2011

Our aim was to evaluate induced changes in pupil and accommodative response for different accommodative stimuli with three different multifocal contact lenses (CLs). Accommodative and pupil responses with three aspheric multifocal CLs of simultaneous focus center near (PureVision Low Add, PureVision High Add and Focus Progressives) for two accommodative stimuli of -2.5 and -4.00 D were recorded in 10 young subjects. Accommodative response, peak velocity, and time constant of accommodation and pupil constriction were assessed. The measurements were evaluated in all the participants with distance-single vision CLs and with the three multifocal CLs. The monocular measurements were performed in…

Comparative Analysis of Patients with Acute Coronary and Cerebrovascular Syndromes from the National French Hospitalization Health Care System Databa…

2010

<i>Background:</i> Nationwide evaluations of the epidemiology of acute coronary syndrome (ACS) or cerebrovascular syndrome (CVS) are scarce. We aimed to analyze nationwide French data on patients referred to hospital for either ACS or CVS. <i>Methods:</i> Using the French national hospital discharge diagnosis records, all patients hospitalized between 2005 and 2008 with a diagnosis of ACS and CVS based on the ICD-10 were identified. We analyzed vascular risk factors and early outcomes in patients with a single hospitalization for ACS or CVS or for both ACV and CVS in a 2-month time window. <i>Results:</i> 1,187,643 patients were recorded. Among these, 638…

Reproducibility of isometric strength: measurement of neck muscles

1999

Abstract Objective. To evaluate the repeatability of an advanced method of measuring the strength of functionally different groups of neck muscles using an isometric apparatus. Design. A repeated measures design was used within and between sessions. Background. Chronic neck pain has been associated with poor isometric neck strength. In rehabilitation, strength measurements may thus help to evaluate the basic condition and show whether or not treatments and exercises have been beneficial for improving strength. Previous tests have concentrated on testing strength while trying to bend forwards and backwards, but no biomechanics device, able to test rotator muscles, has been presented. Method.…

The Long-Term Effects of Physical Loading and Exercise Lifestyles on Back-Related Symptoms, Disability, and Spinal Pathology Among Men

1995

Study design Historical cohort, including selected subgroups. Objectives To understand the long-term effects of exercise on back-related outcomes, back pain, sciatica, back-related hospitalizations, pensions, and magnetic resonance imaging findings were studied among former elite athletes. Summary of background data Exercise and sports participation have become increasingly popular, as have recommendations of exercises for back problems, but little is known about their long-term effects. Methods Questionnaires were returned by 937 former elite athletes and 620 control subjects (83% response rate). Identification codes allowed record linkage to hospital discharge and pension registers. Magne…

PROSAIKA: A prospective multicenter registry with the first programmable gravitational device for hydrocephalus shunting

2015

Abstract Objective Cerebrospinal fluid (CSF) overdrainage is a major problem in shunt therapy for hydrocephalus. The adjustable gravitational valve proSA allows for the first time a targeted compensation for overdrainage in the upright position without interfering with the differential pressure valve. To evaluate benefit, safety and reliability, the multicenter prospective registry PROSAIKA was conducted in 10 German neurosurgical centers. Methods Between March 2009 and July 2010, 120 hydrocephalic patients undergoing first time shunt implantation or shunt revision using proSA entered the study. 93 patients completed the 12 months follow-up. Results Hydrocephalus symptoms were improved in 8…

Operative Treatment of Scoliosis With Cotrel-Dubousset-Hopf Instrumentation

1997

Study design This study analyzes the effects of a new anterior spinal instrumentation system and the results of use in 50 patients with scoliosis. Objectives Anterior spine systems are reviewed. The principles of a new anterior spinal instrumentation system allowing for postoperative care without external support are discussed. Summary of background data Numerous different implants have been presented in the literature for anterior spinal surgery. Nevertheless a primary stable anterior instrumentation was not available for multisegmental procedures until now, and the restoration of lordosis in the lumbar spine was very difficult with the common devices. The development of more stable device…

Handling forces for the use of different inhaler devices.

2019

Abstract Age and comorbidities can impact on the success of handling an inhaler. In this pilot study, we assessed finger strength in 62 participants (aged 5–17 years [n = 20], 18–65 years [n = 22] and > 65 years [n = 20]) by using different types of inhalers with integrated sensors (Respimat®, Breezhaler®, Aerolizer®, Genuair®, Diskus®, Ellipta®, HandiHaler®, Turbohaler® and a pressurized metered-dose inhaler [Atrovent®]). Parameters under investigation included the spontaneous and maximum achievable force and torque required to operate devices. Satisfaction with individual inhalers, and the relationship between satisfaction and strength, were also assessed. There was a marked difference in…

Accuracy of magnetic resonance enterography in the preoperative assessment of patients with Crohn's disease of the small bowel

2016

Aim to assess the accuracy of magnetic resonance-enterography in predicting the extension, location and characteristics of the small bowel segments affected by Crohn's disease. Method This is a prospective study including a consecutive series of 38 patients with small bowel Crohn's disease who underwent surgery at a specialized colorectal unit of a tertiary hospital. Preoperative magnetic resonance enterography was performed in all patients, following a homogeneous protocol, within the three months prior to surgery. A thorough exploration of the small bowel was performed during the surgical procedure, using calibration spheres, according to the discretion of the surgeon. The accuracy of mag…

Changes in anterior chamber eye during accommodation as assessed using a Dual Scheimpflug system

2014

Purpose: To study the changes in anterior chamber depth (ACD), anterior chamber angle (ACA), and pupil diameter (PD) during accommodation. Methods: Eighty eyes of 80 subjects, aged 22 to 40 years, were included. The rotating Dual Scheimpflug and a Placido disc system (Galilei G4, Ziemer Ophthalmic Systems AG, Switzerland) was used to measure the changes in ACD, ACA, and PD during accommodation. ACD measurement was taken for the central zone and for 4 more positions, each in different orientation (nasal, superior, temporal and inferior), 4 mm away from the centre. ACA was measured for the whole eye as well for the nasal, superior, temporal, and inferior quadrants. These metrics were obtained…
