We found inconsistent evidence that the use of an arm support or an alternative mouse may or may not reduce the incidence of neck or shoulder MSDs .
For other physical ergonomic interventions there is no evidence of an effect .
For organisational interventions , in the form of supplementary breaks , there is very low- quality evidence of an effect on upper limb discomfort .
For training and multifaceted interventions there is no evidence of an effect on upper limb pain or discomfort .
BACKGROUND Work-related upper limb and neck musculoskeletal disorders ( MSDs ) are one of the most common occupational disorders worldwide .
Studies have shown that the percentage of office workers that suffer from MSDs ranges from 20 to 60 per cent .
The direct and indirect costs of work-related upper limb MSDs have been reported to be high in Europe , Australia , and the United States .
Although ergonomic interventions are likely to reduce the risk of office workers developing work-related upper limb and neck MSDs , the evidence is unclear .
This is an up date of a Cochrane Review which was last published in 2012 .
OBJECTIVES To assess the effects of physical , cognitive and organisational ergonomic interventions , or combinations of those interventions for the prevention of work-related upper limb and neck MSDs among office workers .
A pilot randomised control trial of the effectiveness of a biofeedback mouse in reducing self-reported pain among office workers
A pilot study examined the effectiveness of a biofeedback mouse in reducing  upper extremity pain and discomfort in office workers ; in addition , relative mouse use ( RMU ) , satisfaction and the feasibility of running a r and omised controlled trial ( RCT ) in a workplace setting were evaluated . The mouse would gently vibrate if the h and was idle for more than 12 s. The feedback reminded users to rest the arm in neutral , supported postures . Analysis showed a statistically significant reduction in shoulder pain and discomfort for the intervention group at T2 ( 38.7 % lower than controls ) . Statistically significant differences in RMU time between groups were seen post intervention ( −7 % at T1 and + 15 % at T2 for the intervention group ) . Fifty-five percent of the intervention group was willing to continue using the mouse . It appears feasible to perform an RCT for this type of intervention in a workplace setting . Further study including more participants is suggested . Practitioner Summary : The study findings support the feasibility of conducting r and omised control trials in office setting s to evaluate ergonomics interventions . The intervention result ed in reduced pain and discomfort in the shoulder . The intervention could be a relevant tool in the reduction of upper extremity musculoskeletal disorder . Further research will better explain the study 's preliminary findings
