Sample Essay
The factors according to which the ergonomics of the workstation are assessed in the above chart include factors like lower extremities, upper extremities, seating surface, seating backrest, work surface, monitor, keyboard, mouse, lighting, temperature, noise and ventilation. The lower extremities section assesses the posture and comfort of the legs and knees.
If the knees are not bent properly or the feet do not touch the floor while sitting strains can occur in the legs which can lead to long term posture issues. The upper extremities access the posture of the above body. A bad upper body posture can result in chronic back pain, spinal cord injury, and hunch backs. The seating surface needs to be adjustable so the user can change its height, tilt and angle to suit their body and posture. An immobile seat surface can strain the user’s body while also being uncomfortable. The seating backrest also needs to be adjustable, as an uncomfortable backrest which does not support the mid lumbar region properly can result in back and spinal cord injuries. The working surface similarly should have adjustable height and should provide all objects within reach while also being free of clutter. This can prevent excess stress on the body of the individual seated at the workstation.
