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 .
BACKGROUND Work-related upper limb and neck musculoskeletal disorders ( MSDs ) are one of the most common occupational disorders around the world .
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 .

Rest break interventions in stoop labor tasks.
H and cultivation and harvest of agricultural products constitute strenuous physical tasks . Working with labor-management ergonomics committees in agricultural setting s , the UC Agricultural Ergonomics Research Center ( AERC ) tested an experimental rest and recovery protocol for its impact on symptoms and productivity during two types of work tasks . The experimental condition consisted of adding a 5 min rest break to every working hour in which there was no other scheduled break ( e.g. , lunchtime ) . This result ed in an additional 20 min of rest per workday . We tested the intervention in two trials : Trial one compared workers ( n=66 ) r and omly assigned to an experimental or a control group during the harvest of commercial strawberries . Trial two utilized a cross-over design ( n=16 pairs of workers ) to compare experimental and control conditions while workers inserted bud grafts into young 18 ' ' high citrus trees . For both trials , workers under the experimental condition reported significantly less severe symptoms than workers under control conditions . The order in which the intervention was given , however , appeared to result in variations in productivity . We conclude that the introduction of frequent , brief rest breaks may improve symptoms for workers engaged in strenuous work tasks
