“…Surface EMG techniques in ergonomics and occupational medicine for prevention and monitoring of occupational disorders were developed in the 90s ( 49 , 187 ) and are currently applied for assessing chairs, posture, occupational tasks, fatigue, and risk at work ( 188 – 190 ). As an example, Figure 8 shows maps of sEMG RMS value (one 0.5 s epoch) of the trapezius muscle of a subject typing with and without forearm rest on the desk.…”

Surface EMG in Clinical Assessment and Neurorehabilitation: Barriers Limiting Its Use

This article addresses the potential clinical value of techniques based on surface electromyography (sEMG) in rehabilitation medicine with specific focus on neurorehabilitation. Applications in exercise and sport pathophysiology, in movement analysis, in ergonomics and occupational medicine, and in a number of related fields are also considered. The contrast between the extensive scientific literature in these fields and the limited clinical applications is discussed. The “barriers” between research findings and their application are very broad, and are longstanding, cultural, educational, and technical. Cultural barriers relate to the general acceptance and use of the concept of objective measurement in a clinical setting and its role in promoting Evidence Based Medicine. Wide differences between countries exist in appropriate training in the use of such quantitative measurements in general, and in electrical measurements in particular. These differences are manifest in training programs, in degrees granted, and in academic/research career opportunities. Educational barriers are related to the background in mathematics and physics for rehabilitation clinicians, leading to insufficient basic concepts of signal interpretation, as well as to the lack of a common language with rehabilitation engineers. Technical barriers are being overcome progressively, but progress is still impacted by the lack of user-friendly equipment, insufficient market demand, gadget-like devices, relatively high equipment price and a pervasive lack of interest by manufacturers. Despite the recommendations provided by the 20-year old EU project on “Surface EMG for Non-Invasive Assessment of Muscles (SENIAM),” real international standards are still missing and there is minimal international pressure for developing and applying such standards. The need for change in training and teaching is increasingly felt in the academic world, but is much less perceived in the health delivery system and clinical environments. The rapid technological progress in the fields of sensor and measurement technology (including sEMG), assistive devices, and robotic rehabilitation, has not been driven by clinical demands. Our assertion is that the most important and urgent interventions concern enhanced education, more effective technology transfer, and increased academic opportunities for physiotherapists, occupational therapists, and kinesiologists.

“…One low-quality RCT provided minimal evidence of a positive effect of the combination of support and rest breaks. Callegari, de Resende, and da Silva Filho (2018) found that hand rest and wrist support can successfully reduce muscle fatigue in the upper limb muscles compared with the effects observed in the control group during a 4-hr prolonged typing task, based on the percentage of fatigued participants.…”

Objective:We present a literature review on workplace physical fatigue interventions, focusing on evaluating the methodological quality and strength of evidence.Background:Physical fatigue is a recognized workplace problem, with negative effects on performance and health-related complaints. Although many studies have focused on the mechanisms and consequences of fatigue, few have considered the effectiveness of interventions to mitigate fatigue.Method:A systematic review of the workplace safety literature for controlled trials of physical fatigue interventions was conducted. Data on intervention type, subject characteristics, targeted tasks and body locations, outcome measures, and study design were extracted. The methodological quality for each study was evaluated using the PEDro scale, and the level of evidence was based on quality, amount, and consistency.Results:Forty-five controlled trials were reviewed, examining 18 interventions. We categorized those interventions into individual-focused ( N = 28 studies, nine interventions), workplace-focused ( N = 12 studies, five interventions), and multiple interventions ( N = 5 studies, four interventions). We identified moderate evidence for interventions related to assistive devices and task variation. There was moderate evidence supporting no fatigue attenuation for the garment change category of interventions. The interventions in the remaining categories had limited to minimal evidence of efficacy. The heterogeneity of the included trials precludes the determination of effect size.Conclusion:This review showed a lack of high levels of evidence for the effectiveness of most physical fatigue interventions.Application:Due to a lack of high levels of evidence for any category of reviewed physical fatigue interventions, further high-quality studies are needed to establish the efficacy of others.

“…12 In a study done with people who did typing it was found that wrist support and hand rest decreased the muscle fatigue of hand muscles. 18 More studies have to be initiated to prevent muscle fatigue in drivers who drive continuously for more than one hour to prevent fatigue and muscle related morbidity. The Government should subsidies active commute to work like public transport and should provide free cycles in order to promote healthy weight gain of adult population.…”

Background: Urbanization has brought a lot of health issues in the citizens. Commuting for work has become more common. People around the world use different means of commute like public transport or driving a car to work. The increase in time of commute may be associated with many health hazards. In this study we try to study the impact of driving duration on hand muscle power.Methods: A prospective cross sectional study was conducted in a tertiary care hospital. About 32 persons who drive car for their work participated in this study after giving their consent. Subjects grouped in to two categories long commuters, who drive for greater or equal to one hour and short commuters less than one hour. Muscle power tested on two occasions immediately after driving and four hour after driving with a help of hand grip dynamometer. Demographic details were collected. The two groups compared for muscle power and body mass index (BMI).Results: The long commuters had less muscle power in comparison with short commuters and it was significant. The average BMI of long commuters was in obesity range were as the average BMI of short commuter is less and it was statistically significant.Conclusions: Driving for greater than one hour is associated with obesity and reduced muscle power immediately after driving.
