An applied science that the average person can use any day of the week, without equipment or Nautilus to improve and maintain your posture and constantly used muscles is referred to as Ergonomics. It is a body of knowledge about human character, human inadequacies and human abilities that are applicable to design. Ergonomic design is the treatment of this mass of knowledge to the design of tasks, systems, tools, machines, environments and jobs for safe, comfortable and effective human use. There are more than twenty technical subgroups within the Human Factors and Ergonomics Society, HFES.

One discipline, often known as "industrial ergonomics," focuses on the physical aspects of work and human abilities such as posture, repetition and force. A second branch, sometimes known as "human factors," is dedicated to the psychological components of work such as mental loading and decision making.

Posture is the position of the body, as you're doing work tasks. Awkward posture is branded with a greater risk for harm. It is usually deemed that the more a joint deviates from the neutral position, the larger the risk of serious harm and injury. Posture predicaments can be created by work methods (twisting and bending just to pick up a box; bending the wrist to assemble a part) or workplace elements (stretched reach to grab an item from a bin at a hard-to-reach location; slouching in the storage bay of a jet plane because of confined space while handling the luggage).

Human factors matters continue to rise in simple systems and consumer products. Some examples contain wireless telephones and other handheld devices that persist to shrink, yet become more complex. A few examples of this is the excess of VCRs blinking "12:00" across the world due to a select number of people who can figure out how to program them, or alarm clocks that allow weary users to inadvertently turn off the alarm when they mean to hit 'snooze'. A user-centered design (UCD) desires to enhance the user-system fit.

An ergonomics specialist can analyze people and can advise changes in the workplace. From the start, employees should be taught suitable posture as they learn the use of computers, machines and tools. They should be encouraged to maintain a natural pace and take advantage of their breaks. In some cases, medical treatment is required. Anti-inflammatory drugs and steroid injections may be prescribed. Surgery may be possible if other methods fail.
