Choosing an ergonomic mouse

What turns a computer mouse into an “ergonomic” accessory?

What are the criteria for an ergonomic mouse?

When purchasing a new mouse, how can we be certain that the mouse touted to be ergonomic does indeed comply with ergonomic criteria?

Does any mice manufacturer have the right to attach the word “ergonomic” to their products?

And is an ergonomic mouse really better than a regular mouse? That is, would an ergonomic mouse helps in preventing carpal tunnel syndrome and inflammations of the wrist?

And last but not least, given the huge assortment of ergonomic mouse devices on the market, how do we know which would be the best and the most appropriate for us?

In order to solve some of these questions, we would first need to determine what exactly is an ergonomic mouse, and what functions are not included in the ergonomic definition.

You might be surprised to know, but the design process of any product involves certain ergonomic considerations.

That being so, basically any product can be called “ergonomic”.

Confused? So am I, but the answer is simple – ergonomic means “suited to the user”. That’s right – Suited to You. That’s the greatest secret of ergonomics.

For example: a small handed girl working with an ergonomic mouse significantly big for her hand or a large man working with a smallish ergonomic mouse will feel very uncomfortable, even though they’re using a mouse that supposedly is ergonomic. An accountant using an extremely narrow or cluttered desk, who chooses to use a large mouse that can hardly be moved on such a desk, will also feel discomfort.

The obvious conclusion is: the mouse should be chosen first and foremost according to body size, work needs and desk format.

Having chosen the ergonomic mouse that fits us we have to ask – would that mouse itself prevent wrist pain?

The answer depends on how we sit and the posture of our hand on the desk.

For example: if we sit too low in respect to our desk, we will not be able to place our hand correctly on the desk, and no ergonomic mouse can or will help us. Or if due to the table structure or the multitude of devices placed on the desk (laptop, telephone, folders… you name it) there is not enough free space to place our wrist, we will not be able to achieve the correct hand posture to benefit from the ergonomic mouse.

So, we understood that we need to choose a mouse that is appropriate to our structure and needs, and have arranged our sitting position and desk to enable us to create the right arm and hand position. The question still remains: Should we buy a mouse defined as ergonomic or can we be satisfied with a simple mouse?

The answer is not that simple. Our best advice would be to try out several mouse devices for a period of time, to feel if there’s any change. I believe some of the ergonomic mouse devices sold today have a structure that definitely lessens the pressure on the hand. Those are worth trying first.

Standardization – an Ergonomic Working Environment at the Office

By gildalit

One of the first things I have noticed as an ergonomic advisor was the lack of uniformity and total absence of any standardization of the working environments at offices and working places.

This is mainly evident when you look at the equipment being used – a haphazard mix of old and new appliances, furniture items and ergonomic equipment. In many offices you can find a medley of different desks and chairs even in a single working space.

How would such a situation be created? There are a ton of different reasons.

For example, many working places might replace malfunctioning or broken equipment, but anything that is still functional gets left as it was.

Another reason could be replacing a specific item or equipment, only for those employees who used some sort of leverage to get their equipment renewed. And sometimes, it’s all about ranks – new and improved equipment is bought for the higher rank workers of the organization, but not for the lower ranks.

Additional reasons might be different decisions reached by different purchasing officers, a decision made by the operational vice president, a change in the budget allocated to acquisition, etc.

What is more clear is that this lack of uniformity can and does create an array of problems:

  1. Those workers left to work with outdated equipment suffer discomfort and pains;
  2. Each working station requires different ergonomic accessories  (which ofcourse entails a higher monetary expenditure);
  3. It is impossible to offer a uniform ergonomic guidance to all workers;
  4. Planning the arrangement of different work stations in one working space is complex and unecessarily problematic;
  5. It is a situation which could create resentment among workers and lead to demands for ergonomic equipment;
  6. And of course this is a situation which could damage the organization’s public image.

Using solid ergonomic advise and planning when getting ready to purchase ergonomic equipment in the early stages of building work stations is a critical step. Good ergonomic advice will allow the organization to create a healthy, ergonomic and uniform work environment.
