OBJECTIVE To assess the impact of post-polio-related fatigue on quality of life. DESIGN Cross-sectional case control study. SUBJECTS Patients without additional health problems that may induce fatigue were selected from among 82 polio survivors. Twenty-six patients with post-polio syndrome and 10 without post-polio syndrome were included. Control group consisted of 30 healthy volunteers. ...

Fatigue at the wheel has been strongly related to car accidents. Traditionally, this phenomenon has been studied in laboratory conditions by means of performance testing. Here, we aimed to improve road safety assessing driver fatigue at the wheel in real scenarios. For this purpose, we have built BioTracker R ©: a flexible non invasive platform. A smartphone and a microcontroller unit are the c...

This study proposes an investment for the evaluation of fatigue cracks by eddy current testing (ECT). Fatigue cracks (FC) manufactured on SUS316 plates are detected using ECT. Inverse analysis is applied to the ECT signals and both crack depth and length are estimated. Two models are applied, one is the EDM model without conductivity, and the other is the SCC model with partial conductivity. Th...

Flooring may play a role in standing fatigue, however previous studies of flooring on subjective and objective measures thought to be related to fatigue/discomfort, have had mixed results. The majority of the differences in the reported results are probably due to differences in procedures and analysis methods, particularly variations in testing duration and exposure time. The impact of floorin...

To investigate the biomechanical performances of artificial cervical disc (ACD) prostheses, many studies have been conducted, either with sections cadavers under physiological loads or block-like testing fixtures obeying ASTM F2346 standard. Unfortunately, both methods are almost impossible to utilize for accurate results lifetime anti-fatigue experiments at least 10 million cycles due difficul...

BACKGROUND The DASCOR device has recently been introduced as an innovative nucleus replacement alternative for the treatment of low-back pain caused by degenerative intervertebral disc disease. The purpose of this study was to characterize, through a series of preclinical mechanical bench and biomechanical tests, the effectiveness of this device. METHODS A number of samples were created using...
