• Description:
  A pilot study was conducted to determine the normal use of the mailbag, establish general performance parameters and obtain subjective opinions of alternative designs from postal personnel. The alternative mailbags were modified slightly in response to this data and two laboratory studies were then performed to measure the effect of the alternative mailbag designs on metabolic load and on fatigue in the lateral trunk flexor muscles. The two types of alternative bags each included waist support and one split the load into two parts. The use of the alternative bags brought about no significant change in metabolic load. Both alternative mailbags did result in significantly less lateral trunk muscle fatigue. The authors suggest that the reduction in fatigue would result in reduced musculoskeletal stress and lower the potential for back injury. [Description provided by NIOSH]
