Reynolds, J. L., Drury, Colin G., Sharit, Joseph and Cerny, F. (1994): The Effects of Different Forms of Space Restriction on Inspection Performance. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 631-635.

Work in restrictive spaces is characteristic of many tasks, particularly in maintenance and inspection operations. The nature of the spatial restriction as well as its magnitude is likely to affect the worker's response to the space. This research measured the effects of three different spatial restrictions (vertical (V), sagittal (S) and combined (VS)) on an inspection task. The effects of the three restrictions on postural adaptation, physiological response, psychophysical reports and task performance were qualitatively different. Generally, the VS and V restrictions caused increases in operator stress and workload, with these effects being most severe under the VS restriction. Conversely, the S restriction caused no increases in operator stress and tended to improve performance. Thus, while restrictions are generally detrimental, certain mild restrictions may actually facilitate jobs.
