Implementation of expert systems to support the functional evaluation of stand-to-sit activity
Source, 2 hours ago
Background: Functional evaluation of sit-to-stand and stand-to-sit activities is often used by physiotherapists in patients with neurological and musculoskeletal disorders. The observation of the way these activities are executed is essential in identifying kinesiological problems. There are differe...
Experimental study of PLLA/INH slow release implant fabricated by three dimensional printing technique and drug release characteristics in vitro
Source, July 19, 2014
Background: Local slow release implant provided long term and stable drug release in the lesion. The objective of this study was to fabricate biodegradable slow release INH/PLLA tablet via 3 dimensional printing technique (3DP) and to compare the drug release characteristics of three different struc...
Validation of the pulse decomposition analysis algorithm using central arterial blood pressure
Source, July 08, 2014
Background: There is a significant need for continuous noninvasive continuous blood pressure (cNIBP) monitoring, especially for anesthetized surgery and ICU recovery. cNIBP systems could lower costs and expand the use of continuous blood pressure monitoring, lowering risk and improving outcomes.The ...
An in-situ calibration method and the effects on stimulus frequency otoacoustic emissions
Source, July 07, 2014
Background: The interference between the incoming sound wave and the acoustic energy reflected by the tympanic membrane (TM) forms a standing wave in human ear canals. The existence of standing waves causes various problems when measuring otoacoustic emissions (OAEs) that are soft sounds closely rel...
Machine learning, medical diagnosis, and biomedical engineering research - commentary
Source, July 05, 2014
A large number of papers are appearing in the biomedical engineering literature that describe the use of machine learning techniques to develop classifiers for detection or diagnosis of disease. However, the usefulness of this approach in developing clinically validated diagnostic techniques so far ...
Quantitative assessment of the impact of biomedical image acquisition on the results obtained from image analysis and processing
Source, July 04, 2014
IntroductionDedicated, automatic algorithms for image analysis and processing are becoming more and more common in medical diagnosis. When creating dedicated algorithms, many factors must be taken into consideration. They are associated with selecting the appropriate algorithm parameters and taking ...
Sparse CT reconstruction based on multi-direction anisotropic total variation (MDATV)
Source, July 03, 2014
Background: The sparse CT (Computed Tomography), inspired by compressed sensing, means to introduce a prior information of image sparsity into CT reconstruction to reduce the input projections so as to reduce the potential threat of incremental X-ray dose to patients'' health. Recently, many remarka...
Posterior cruciate ligament balancing in total knee arthroplasty: a numerical study with a dynamic force controlled knee model
Source, July 02, 2014
Background: Adequate soft tissue balancing is a key factor for a successful result after total knee arthroplasty (TKA). Posterior cruciate ligament (PCL) is the primary restraint to posterior translation of the tibia after cruciate retaining TKA and is also responsible for the amount of joint compre...
Clinical implication of interface pressure for a new prosthetic suspension system
Source, June 30, 2014
Background: Prosthesis suspension systems can alter the distribution of pressure within the prosthetic socket. This study evaluates a new suspension system for lower limb prostheses, and aims to compare the interface pressure and amputees'' satisfaction with the new system compared with a common pro...
A new hierarchical method for inter-patient heartbeat classification using random projections and RR intervals
Source, June 30, 2014
Background: The inter-patient classification schema and the Association for the Advancement of Medical Instrumentation (AAMI) standards are important to the construction and evaluation of automated heartbeat classification systems. The majority of previously proposed methods that take the above two ...
