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 .

Although ergonomic design and training are likely to reduce the risk of workers developing work-related upper limb and neck MSDs , the evidence is unclear .

A Randomized Controlled Trial to Prevent Patient Lift and Transfer Injuries of Health Care Workers
Study Design . R and omized controlled trial ( RCT ) . Objectives . To compare the effectiveness of training and equipment to reduce musculoskeletal injuries , increase comfort , and reduce physical dem and s on staff performing patient lifts and transfers at a large acute care hospital . Summary of Background Data . Back injury to nursing staff during patient h and ling tasks is a major issue in health care . The value of mechanical assistive devices in reducing injuries to these workers is unclear . Methods . This three-armed RCT consisted of a “ control arm , ” a “ safe lifting ” arm , and a “ no strenuous lifting ” arm .  A medical , surgical , and rehabilitation ward were each r and omly assigned to each arm . Both intervention arms received intensive training in back care , patient assessment , and h and ling techniques . Hence , the “ safe lifting ” arm used improved patient h and ling techniques using manual equipment , whereas the “ no strenuous lifting ” arm aim ed to eliminate manual patient h and ling through use of additional mechanical and other assistive equipment . Results . Frequency of manual patient h and ling tasks was significantly decreased on the “ no strenuous lifting ” arm . Self-perceived work fatigue , back and shoulder pain , safety , and frequency and intensity of physical discomfort associated with patient h and ling tasks were improved on both intervention arms , but staff on the mechanical equipment arm showed greater improvements . Musculoskeletal injury rates were not significantly altered . Conclusions . The “ no strenuous lifting ” program , which combined training with assured availability of mechanical and other assistive patient h and ling equipment , most effectively improved comfort with patient h and ling , decreased staff fatigue , and decreased physical dem and s. The fact that injury rates were not statistically significantly reduced may reflect the less sensitive nature of this indicator compared with the subjective indicators
