Studies of the biomechanical and physiological mechanisms of action concerning the prophylactic use of back belts to prevent occupational low back injuries are limited in number and present conflicting findings. The epidemiological data concerning the efficacy of back belts in the prevention of occupational low back injuries are not sufficient to warrant general use of back belts in the occupational setting for uninjured workers. There is actually a potential for increasing the degree of low back injury with general application of back belts in occupational settings. In sum, there are insufficient data in the scientific literature to indicate that general use of back belts in occupational settings is appropriate for uninjured workers. Because the increase in use of soft canvas back belts has been fairly recent, physical and epidemiological studies pertaining specifically to soft canvas back belts are extremely limited. The sample size of many physical investigations also is extremely limited. In many instances, studies concerning the role of back belts in preventing occupational low back injuries have examined conditions that do not apply directly to the use of soft canvas back belts. For these reasons, further studies in both the physical and epidemiological realms are necessary before it is appropriate to use commonly constructed back belts as personal protective equipment in occupational settings.
关于预防性使用背带来预防职业性腰伤的生物力学和生理作用机制的研究数量有限,且结果相互矛盾。关于背带在预防职业性腰伤方面功效的流行病学数据不足以保证在职业环境中未受伤的工人普遍使用背带。实际上,在职业环境中普遍使用背带存在增加腰伤程度的可能性。总之,科学文献中没有足够的数据表明在职业环境中未受伤的工人普遍使用背带是合适的。由于软帆布背带的使用增加是最近才出现的,专门针对软帆布背带的物理和流行病学研究极其有限。许多物理调查的样本量也极其有限。在许多情况下,关于背带在预防职业性腰伤中作用的研究考察的条件并不直接适用于软帆布背带的使用。由于这些原因,在将普通构造的背带作为职业环境中的个人防护装备使用之前,有必要在物理和流行病学领域进行进一步研究。
