“…In order to remove the common signals, a differential amplifier with a high common-mode rejection ratio (CMRR) was used to cancel the common signal and amplify the difference in the input signal. An AD620 differential amplifier with a minimum rejection ratio of 100 dB, which is comparable to the standard proposed by surface EMG for the noninvasive assessment of muscles (SENIAM) and exceeds the recommended minimum of 90 dB, 32,37 was proposed for the developed acquisition system.…”

This article describes the design of a robust, inexpensive, easy-to-use, small, and portable online electromyography acquisition system for monitoring electromyography signals during rehabilitation. This single-channel (one-muscle) system was connected via the universal serial bus port to a programmable Windows operating system handheld tablet personal computer for storage and analysis of the data by the end user. The raw electromyography signals were amplified in order to convert them to an observable scale. The inherent noise of 50 Hz (Malaysia) from power lines electromagnetic interference was then eliminated using a single-hybrid IC notch filter. These signals were sampled by a signal processing module and converted into 24-bit digital data. An algorithm was developed and programmed to transmit the digital data to the computer, where it was reassembled and displayed in the computer using software. Finally, the following device was furnished with the graphical user interface to display the online muscle strength streaming signal in a handheld tablet personal computer. This battery-operated system was tested on the biceps brachii muscles of 20 healthy subjects, and the results were compared to those obtained with a commercial single-channel (one-muscle) electromyography acquisition system. The results obtained using the developed device when compared to those obtained from a commercially available physiological signal monitoring system for activities involving muscle contractions were found to be comparable (the comparison of various statistical parameters) between male and female subjects. In addition, the key advantage of this developed system over the conventional desktop personal computer-based acquisition systems is its portability due to the use of a tablet personal computer in which the results are accessible graphically as well as stored in text (comma-separated value) form.

“…Beside cadaver studies, in vivo studies were done to determine the best electrode locations. De Nooij et al (2009) evaluated the influence of electrode location on surface EMG amplitude of the ES pars longissimus dorsi by placing additional electrodes on 16 healthy subjects during five different tasks (standing, forward flexion, re-extension, unsupported sitting and arm/leg lifting). Two electrodes were located according to the SENIAM guidelines for electrode positions and substantial cranial, caudal and lateral electrode dislocations were simulated by placing four additional electrodes.…”

“…Two electrodes were located according to the SENIAM guidelines for electrode positions and substantial cranial, caudal and lateral electrode dislocations were simulated by placing four additional electrodes. They concluded that lateral dislocation results in an average decrease of 18% in surface EMG amplitude, that caudal and cranial dislocation does not cause a change in surface EMG amplitude and that the variability caused by electrode dislocation is comparable to the variability caused by repetitions of tasks or by electrode repositioning (De Nooij et al, 2009). The studies in our review reported the electrode placement for the ES on a distance from 2 to 9 cm lateral from the spine, what in accordance to the study of De Nooij et al (2009) would give changes in SEMG amplitude.…”

“…Despite the international recommendations on the placement of the surface EMG electrodes on the muscle belly (Hermens et al, 1999;Seniam, 2010) and studies to determine the best electrode locations for the trunk muscles (De Nooij et al, 2009;) the literature is not consistent on these recommendations, what makes it difficult to compare the results of different studies.…”

“…De Nooij et al (2008) developed recently a special garment to make long recordings of the low back muscles possible. To test the feasibility of independent use, he investigated the effects of misplacement of the garment by simultaneously recording of the EMG at several locations with a distinct displacement of the electrodes simultaneously.…”

The growing number of elderly and people with chronic disorders in our western society puts such pressure on our healthcare system that innovative approaches are demanded to make our health care more effective and more efficient. One way of innovation of healthcare can be obtained by introducing new services which enable less pressure on the intramural health care and support a more independent living and self efficacy of patients. Two of such services are Remote monitoring and remotely supervised training (RMT). Remote monitoring enables freedom to the patient with the assurance that assistance is possible whenever required. Remotely supervised treatment enables efficient and effective user-centred training anywhere and anytime with an intensity not feasible in an intramural setting. It is our vision that remote monitoring and remotely supervised treatment applications will become very important for patients (safety, more in control, convenience), health care insurances (efficiency, cost reduction) and healthcare service providers (more effective, innovative).A schematic drawing of the main components and the information exchange pathways are shown in the figure below. RMT systems are in general quite complex, requiring dependable end-to-end systems integrating ambulant sensing of relevant biosignals and context information, an M-Health platform for a secure data transport and storage and a backend system with appropriate decisions support with respect to both technical and clinical aspects. Another key element is the feedback of the information (dotted lines), which is essential for the subject and the care providers to learn from the data and to make the appropriate decisions. Feedback Sensing Care & CoachingDuring the past years considerable knowledge and experience is being gained with the research and development of such smart systems. In parallel, experience is gained with respect to the implementation of RMT systems in a clinical environment and how to assess its potential benefits. Examples concern: Activity monitoring in low back pain: the daily activity patterns of patients with chronic low back pain have been assessed, indicating a similar amount of total daily activity compared to healthy subjects but with a different distribution over the day. The results clearly show in general a higher activity level in the morning and lower activity levels in the afternoon and evening. This provides a starting point for treatment: restore the balance in acivity pattern by providing adequate personalised feedback Monitoring of spasticity: continuous monitoring of muscle activity patterns by means of surface EMG measurement, in subjects with a spinal cord lesion provides insight in the magnitude and distribution of spasticity over the day. It gives direct objective and quantitative information during which activities and during which part of the day spasticity is most hindering the activities of daily living and as such it provides valuable information to optimise the drug delivery to decrease spasticity.
