There was low- to very low- quality evidence that other interventions were not effective in reducing work-related upper limb and neck MSDs in adults .
We found moderate- quality evidence to suggest that the use of arm support with alternative mouse may reduce the incidence of neck/shoulder MSDs , but not right upper limb MSDs .
Moreover , we found moderate- quality evidence to suggest that the incidence of neck/shoulder and right upper limb MSDs is not reduced when comparing alternative and conventional mouse with and without arm support .
However , given there were multiple comparisons made involving a number of interventions and outcomes , high- quality evidence is needed to determine the effectiveness of these interventions clearly .
While we found very-low- to low- quality evidence to suggest that other ergonomic interventions do not prevent work-related MSDs of the upper limb and neck , this was limited by the paucity and heterogeneity of available studies .

Orchard Evaluation of Ergonomically Modified Apple Bucket
Abstract Background : While preliminary laboratory tests indicate that a hip belt reduces the load on the back , neck and shoulders associated with musculoskeletal strain , an orchard trial is needed to more realistically assess both effectiveness and acceptability . Objective : to evaluate the hip belt 's effectiveness in three areas : worker acceptance , worker productivity , and one-day muscle fatigue of the back and shoulder . Methods : Ninety-six New York apple harvest workers were r and omly assigned to use the intervention hip belt or placebo belt for one week . In a second week all workers switched conditions . Subjects were interviewed at the end of each week to ascertain intervention acceptance . Employer records were review ed to determine bushels picked per day . Subjects also underwent muscle fatigue testing at the beginning and again at the end of one workday during each week . Results : Ninety-one percent of the subjects favored the intervention hip belt . Use of the intervention did not appreciably slow picking speed ( bushels per hour ) as compared to placebo ( 8.8 bu/ hr vs. 8.89 bu/hr ) . Both were significantly faster than the regular equipment condition ( 8.13 bu/hr ) . No significant differences in one-day muscle fatigue were found with intervention use . Conclusions : The belt was acceptable to the workers and did not hinder productivity . However , the anticipated ergonomic benefits were not demonstrable using one-day strength testing
