The purpose of this study was to examine the effects of 12 weeks collagen peptide (CP) supplementation on knee pain and function in individuals with self-reported knee pain. Healthy physically active individuals (n = 167, aged 63 [interquartile range = 56-68] years) with self-reported knee pain received 10 g/day of CP or placebo for 12 weeks....

The aim of this review was to provide an overview of assistive exoskeletons that have specifically been developed for industrial purposes and to assess the potential effect of these exoskeletons on reduction of physical loading on the body. The search resulted in 40 papers describing 26 different industrial exoskeletons, of which 19 were active ...

Exoskeletons may form a new strategy to reduce the risk of developing low back pain in stressful jobs. In the present study we examined the potential of a so-called passive exoskeleton on muscle activity, discomfort and endurance time in prolonged forward-bended working postures.Eighteen subjects performed two tasks: a simulated assembly task...

The focus of this study was to establish a relationship between physical discomfort and performance. Eleven healthy male subjects participated in this pilot study. The subjects performed a 2-h protocol without and with significant thermal and mechanical discomfort. Various cognitive tasks were executed repeatedly during the protocol to evaluate...

Background: There is a demand for interiors to support other activities in a car than controlling the vehicle. Currently, this is the case for the car passengers and-in the future-autonomous driving cars will also facilitate drivers to perform other activities. One of these activities is working with handheld devices. Objective: Previous...

The term comfort is often seen relating to the marketing of products like chairs, cars, clothing, hand tools and even airplane tickets, while in the scientific literature, the term discomfort shows up often, since it is used in research. Few papers explain the concept of a localized comfort experience in relation to product use, although people...

In the present study, we investigated the effect of office tasks on posture and movements in field settings, and the comfort rating for chair characteristics and correlation with type of task. The tasks studied were: computer work, telephoning, desk work and conversation. Postures, movements, chair part inclinations and comfort rating data were...

Vehicle interiors for working while travelling have certainly room for improvement. In this paper, travelers in the rear seat of a car using a laptop, a tablet and a book were observed and questioned. Additionally, EMG recordings were made in these three conditions. It appeared that the seat dictates the posture; the discomfort is low after 30...

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,...

Is artisans' comfort in using hand tools a necessity or a luxury? Ergonomically well-designed hand tools, which provide comfort to the user, decrease the risk of occupational health problems and increase the job performance. Therefore, it is not a luxury, but rather a necessity that hand tools be designed with a focus on comfort, and that...

TNO and BMA Ergonomics are developing a so-called smart office chair. This chair is supposed to provide feedback on postures and movements during seated office work. The feedback should enable the user (i.e. the worker doing VDU tasks) to perform his or her work with less discomfort and in a more productive way. One part of this project is a...

The objective of this prospective cohort study was to evaluate if peak or cumulative musculoskeletal discomfort may predict future low-back, neck or shoulder pain among symptom-free workers. At baseline, discomfort per body region was rated on a 10-point scale six times during a working day. Questionnaires on pain were sent out three times...

In the current study, the relationship between objective measurements and subjective experienced comfort and discomfort in using handsaws was examined. Twelve carpenters evaluated five different handsaws. Objective measures of contact pressure (average pressure, pressure area and pressure-time (P-t) integral) in static and dynamic conditions,...

Background: Epidemiologic studies suggest that garlic may have beneficial effects on risk factors associated with cardiovascular disease (CVD). However, these findings are not unambiguously supported by randomized placebo-controlled clinical trials. Objective: We sought to investigate the effects of a chemically well-characterized garlic...

The relationships of objective measurements (contact pressure and productivity) with subjective experienced comfort and discomfort in using hand saws was examined. Professional carpenters evaluated five different hand saws. The pressure-time integral during the static pressure measurement (beta = –0.24, p<.01) was highly related to comfort and...

World-wide a concern exists about the influence of man-made noise on marine life and particularly on marine mammals and fish. One of the acoustic polluters of the world’s oceans is high-power active sonar, but also pile driving and seismic activities at sea are of concern with respect to animal welfare. At TNO, acoustic criteria are being...

One of today's major challenges in manufacturing industries is the maximization of flexibility. One aspect of flexibility concerns the ability to deal with the fluctuations in the volume demand. Many companies are exposed to relatively short periods of times (about one or two months), where volume demands are significantly higher compared to the...

The aim of the study was to identify predictors of comfort and discomfort in using hand tools. For this purpose, the comfort questionnaire for hand tools (CQH) was developed based on the results of a previous study. In the current study, four screwdrivers were evaluated on comfort (expected comfort at first sight and comfort after short time use...

To design comfortable hand tools, knowledge about comfort/discomfort in using hand tools is required. We investigated which factors determine comfort/discomfort in using hand tools according to users. Therefore, descriptors of comfort/discomfort in using hand tools were collected from literature and interviews. After that, the relatedness of a...
