This study investigated temporal changes in movement strategy and performance during fatiguing short-cycle work. Eighteen participants performed six 7-min work blocks with repetitive reaching movements at 0.5 Hz, each followed by a 5.5-min rest break for a total duration of 1 h. Electromyography (EMG) was collected continuously from the upper...

This study investigated the effect of work pace on workload, motor variability and fatigue during light assembly work. Upper extremity kinematics and electromyography (EMG) were obtained on a cycle-to-cycle basis for eight participants during two conditions, corresponding to "normal" and "high" work pace according to a predetermined time system...

The purpose of this study was to determine whether objective electromyographical manifestations of muscle fatigue develop in the upper trapezius muscle in two assembly tasks involving contractions of different low-intensity levels (8% and 12% MVC) and whether these indications of fatigue are homogeneously distributed across different muscle...

The aim of the study was to investigate the effectiveness of a resistance-training program on muscle strength of the back and neck/shoulder muscles, relative physical workload, muscle fatigue and musculoskeletal discomfort during a simulated assembly and lifting task. Twenty-two workers were randomized over an 8-week resistance-training group,...

In dit artikel wordt een overzicht gegeven van een aantal veel besproken theorieen omtrent het ontstaan van RSI die te maken hebben met stoornissen van spieren. Deze theorieen zijn in een model gevat welke hier gepresenteerd wordt (eerder verschenen in Geneeskunde en Sport. 2005;38(1): 7-73). Dit is een achtergrond artikel bij de workshop ...

A review of the literature on the pathophysiology of upper extremity muscle disorders (UEMDs) was performed. An overview is given of clinical findings and hypotheses on the pathogenesis of UEMDs. The literature indicates that disorders of muscle cells and limitations of the local circulation underlie UEMDs. However, these disorders identified do...

The object of the current study was to determine whether static contraction of proximal musculature has an effect on the blood flow more distally in the upper extremity. Static contractions of muscles in the neck shoulder region at three levels (relaxed, shoulders elevated and shoulders elevated loaded with 4.95 kg each) were combined with...

This paper presents an overview of theories concerning the development of RSI (repetitive strain injury), related to muscle disorders. Movement is a noisy process. The level of noise is affected by factors such as fatigue and psychosocial stress. In order for precision movements to be made in such situations, an increased level of muscle...

The objective of the present study was to gain insight into the effects of precision demands and mental pressure on the load of the upper extremity. Two computer mouse tasks were used: an aiming and a tracking task. Upper extremity loading was operationalized as the myo-electric activity of the wrist flexor and extensor and of the trapezius...

High precision demands in manual tasks can be expected to cause more selective use of a part of the muscular synergy involved. To test this expectation, load sharing of the index finger and middle finger was investigated during a pinching task. Myoelectric activation of lower arm and neck-shoulder muscles was measured to see if overall level of...

In dit artikel wordt het congres 'Ergonomics in the digital age' van de International Ergonomics Association besproken. Dit thema werd inhoudelijk uitgewerkt in enkele van de sessies. Verder waren er veel sessies over veiligheid, 'human performance', en 'automotive ergonomics'. Verschillende symposia waren door Nederlanders georganiseerd -...

Een belemmerde bloedtoevoer naar werkende spieren wordt vaak genoemd als veroorzaker van RSI-klachten. Doel van het hier beschreven onderzoek was het bepalen van de invloed van knijpkracht en schouderbelasting op de bloedtoevoer naar de onderarm tijdens een intermitterende knijptaak. Tijdens de knijptaak en de daaropvolgende herstelperiode werd...

Rustpauzes tijdens bijvoorbeeld beeldschermwerk worden geadviseerd als middel ter preventie van RSI. In veel gevallen wordt geadviseerd in deze pauzes oefeningen te doen. Hoewel oefeningen de doorbloeding van spieren zouden kunnen bevorderen, is ook denkbaar dat vermoeidheid door oefeningen wordt versterkt. Het doel van deze studie was het...

Force and frequency in manual handling tasks are known risk factors for work related upper arm disorders. Three force levels and three frequencies are used to define the external load in a pinching task. The effects of these external loads on subjective and objective responses are studied. Subjective ratings poorly reflect the levels of external...

City officials from Haarlem, a Dutch city in which one of the first scientific studies on the workload of refuse collectors was performed, wanted to compare the work situation and physical workload in 1997 with the results of a study performed in Haarlem in 1985 and with the results of a national study conducted in 1993. Depending on the results...
