Armrests that cannot be adequately adjusted for the user is a major red flag. Their researchers found moderate evidence of an optimally adjusted arm support with the reduction of an arm injury. This fact is supported by the systematic review completed by the Institute for Work and Health in Toronto a couple of years ago. If this is in place (super-adjustability in height, length, and width), arm supports can be somewhat beneficial at reducing arm injury or discomfort. In the majority of cases (like 99.9%) this means that the arms are resting along the person’s torso – the elbow is pretty much directly under the shoulder. To work in a neutral position, the arms and shoulders should be in a resting position. Theoretically this working posture will not expose the user to any ergonomic risk in developing discomfort or injury, nor will it contribute to any pain or discomfort related to a past injury. Instead, the upper arm is comfortably tucked next to their torso when they are working. The shoulders are not raised or depressed, nor is the upper arm flexed away (called abduction) from the user’s torso. An armrest essentially carries the weight of the arm so that the shoulders can ‘rest’. A neutral shoulder posture is the best position possible to keep the shoulders relaxed. Keep this in mind when thinking about armrests.įor reference: Optimally placed armrests should slide just underneath a neutral elbow position so that the shoulders stay in a neutral (aka comfortable) posture. Remember ergonomics is here to adjust the work environment to fit the person, not the other way around. Everything is perfect.Įrgonomic risk occurs when armrests can’t be fully adjusted to fit the user like a glove. An optimal ergonomic set-up is when armrests can be fully adjusted (adequate height, width, and length) to fit the user like a glove. It depends on a few things to whether or not armrests are the best ergonomic solution for a particular person. In this post I’m going to share insights about both arguments as well as some of the reasoning behind it. But at the same time there are others who say that the best possible posture can only be attained with no armrests attached to the chair. There are those who insist that armrests must always be attached. So the Question is: Do you use armrests? The answer is quite dividing. If you are new to the ergonomics community, nothing divides us like whether or not armrests should be used in the office. So what do we do? Well one solution that has been proposed is it to use arm supports aka armrests. Maybe it’s a bit obvious… but research now supports it! It’s no surprise that upper body discomfort in the arms and neck are common and on the rise too. Computer based customer service work aka call centre work is one of the most rapidly growing occupations in the world according to this research.
