Summary on Critique article “A new table for work on Microscope”

Introduction

Microscope workers are exposed to continuous static muscular work and an increased risk for musculoskeletal disorders in the neck, shoulder and upper extremities. As a consequence of this ergonomic problem initiation was made to design a Table that would suffice all the needs of microscope worker. The new table allowed the microscope to be used with the head in an upright position the forearms supported and with less flexion of the upper arm.

Summary

* The new table had a height adjustable and tiltable middle section on which the microscope was placed along with adjustable right and left sections. Finally a section at the front of the table was cut-away so that the operators could place their forearms on the table. The new table allowed the microscope to be used with the head in an upright position and the forearms supported and with less flexion of the upper arm.

* Many subjects were asked to work on old as well as new Microscope table.

* Different scientific methods such as Electromyography and Normalization where used to determine the muscular load on neck-shoulder region.

* The objective of this study was to compare the effects of working with the new microscope table on muscular load in the neck–shoulder region during a standardized microscope task with the effects of working on an ordinary non-adjustable laboratory table

* Electromyography-The dependent variable is the electromyographic (EMG) activity measured from muscles in the neck-shoulder region.

* We found that the new table allowed the microscope oculars to be used at the correct height,as determined by the more upright position of the head and the reduced muscle activity in the neck.

Results

Nine of the ten subjects reported that work at the new table was lighter or much lighter than at the old table and eight subjects found working at the new...
