Objectives System identification techniques have the potential to assess the contribution of the underlying systems involved in standing balance by applying well-known disturbances. We investigated the reliability of standing balance parameters obtained with multivariate closed loop system identification techniques. Methods In twelve healthy...

The construct of the General Purpose Technology misses its micro-foundation (as observed by Richard Lipsey). We present a possible solution in the General Purpose Engines. These are the basic innovations and the clusters of contributing and derived innovation, that appear in a Schumpeterian 'cluster of innovations'. These cluster are the basis...

This case study is a historic analysis of the developments that resulted in the electric telephone. It is a story about human communication. Long distance communication that had already developed with the electrical telegraph system created by Samuel Morse in America and Cooke & Wheatstone in Britain. But now electricity became—next to its...

This case study is a historic analysis of the developments that resulted in the electric telegraph. It describes a fascinating development in the early nineteenth century. It is a story about communication. Long distance communication, that had already developed with the optical semaphore system created by Claude Chappe in revolutionary France....

The application of games for behavioral change has seen a surge in popularity but evidence on the efficacy of these games is contradictory. Anecdotal findings seem to confirm their motivational value whereas most quantitative findings from randomized controlled trials (RCT) are negative or difficult to interpret. One cause for the contradictory...

This case study is a historic analysis of the developments that resulted in the electric light. The range of inventions that started with the demonstrations of a sparkling bright light by the Englishman Humphry Davy and the Russian Vasilii Petrov in the early nineteenth century, over the next century culminated into the invention of the...

This casestudy is a historic analysis of the developments that resulted in the electro-motive engines. It shows the range of inventions that started with Volta’s wet cell, Oersteds moving compass needle, Faradays homopolar motor and Surgeon’s electromagnet, the first steps leading to the electro-motor were taken. Contributions from American,...

This casestudy is a historic analysis of the developments that resulted in the steam engine. The range of inventions that started with Savery's 'Miner's Friend' (a water pump to solve the dramatic water problem in the British eighteenth century mines) over a century culminated in the steam engine used to power factories, coaches, locomotives and...

Balance control (the ability to maintain an upright posture) is asymmetrically controlled in a proportion of patients with Parkinson’s disease. Gait asymmetries have been linked to the pathophysiology of freezing of gait. We speculate that asymmetries in balance could contribute to freezing by a) hampering the unloading of the stepping leg and...

Neuroprosthetic technology and robotic exoskeletons are being developed to facilitate stepping, reduce muscle efforts, and promote motor recovery. Nevertheless, the guidance forces of an exoskeleton may influence the sensory inputs, sensorimotor interactions and resulting muscle activity patterns during stepping. The aim of this study was to...

Background There is increasing interest in the use of robotic gait-training devices in walking rehabilitation of incomplete spinal cord injured (iSCI) individuals. These devices provide promising opportunities to increase the intensity of training and reduce physical demands on therapists. Despite these potential benefits, robotic gait-training...

Background Stroke survivors often have difficulties in manipulating objects with their affected hand. Thumb control plays an important role in object manipulation. Surface functional electrical stimulation (FES) can assist movement. We aim to control the 2D thumb force by predicting the sum of individual muscle forces, described by a sigmoidal...

This paper focusses on the definition of the word ‘innovation’ as used in scholarly manuscripts (books and articles) about the topic of Innovation. The research was done in 1988, and reported in the Dutch Language in a Research Paper of the University of Eindhoven (The Netherlands). As preparation for a comparable larger study in 2013, the...

Background Gait training robots should display a minimum added inertia in order to allow normal walking. The effect of inertias in specific directions is yet unknown. We set up two experiments to assess the effect of inertia in anteroposterior (AP) direction to the ankle and AP and mediolateral (ML) direction to the pelvis. Methods We developed...

Background Human stance involves multiple segments, including the legs and trunk, and requires coordinated actions of both. A novel method was developed that reliably estimates the contribution of the left and right leg (i.e., the ankle and hip joints) to the balance control of individual subjects. Methods The method was evaluated using...

Background Robot-aided gait training is an emerging clinical tool for gait rehabilitation of neurological patients. This paper deals with a novel method of offering gait assistance, using an impedance controlled exoskeleton (LOPES). The provided assistance is based on a recent finding that, in the control of walking, different modules can be...

The different measures used to characterize postural sway are sensitive to variations in sampling duration, yet there remains marked variability and a lack of consistency in this temporal parameter when compared between studies. We investigated the effect of sampling duration on 22 commonly used frequency and time domain measures and stabilogram...

Background: In many stroke patients arm function is limited, which can be related to an abnormal coupling between shoulder and elbow joints. The extent to which this can be translated to activities of daily life (ADL), in terms of muscle activation during ADL-like movements, is rather unknown. Therefore, the present study examined the occurrence...
