Abstract

The effect of screen based keyboard (SBK) operation on extensibility of the neural system was investigated using the radial nerve upper limb tension test (Butler 1991). Twenty-five female subjects (aged 17–55 years) including 15 SBK operators and 10 non-SBK operators who acted as a control were examined. Mean glenohumeral abduction in the upper limb tension test in the control group was 40 degrees. In the SBK operators, it was 27 degrees (right side) and 30 degrees (left side). Statistical analysis showed a significant difference between the groups. Results indicate that the normal mechanics of the neural system may be affected by SBK operation and that neural tension warrants consideration in the prevention and management of work related neck and upper limb disorders. © 1995, Australian Physiotherapy Association.
