There was strong evidence for one intervention category , resistance training , leading to the recommendation : Implementing a workplace-based resistance training exercise programme can help prevent and manage UEMSD and symptoms .
The synthesis also revealed moderate evidence for stretching programmes , mouse use feedback and forearm supports in preventing UEMSD or symptoms .
There was also moderate evidence for no benefit for EMG biofeedback , job stress management training , and office workstation adjustment for UEMSD and symptoms .
The burden of disabling musculoskeletal pain and injuries ( musculoskeletal disorders , MSDs ) arising from work-related causes in many workplaces remains substantial .
There is little consensus on the most appropriate interventions for MSDs .
Our objective was to up date a systematic review of workplace-based interventions for preventing and managing  upper extremity MSD ( UEMSD ) .
Kettlebell training for musculoskeletal and cardiovascular health: a randomized controlled trial.
OBJECTIVE The aim of this trial was to investigate the effectiveness of a worksite intervention using kettlebell training to improve musculoskeletal and cardiovascular health . METHODS This single-blind r and omized controlled trial involved 40 adults from occupations with a high prevalence of reported musculoskeletal pain symptoms ( mean age 44 years , body mass index 23 kg/m² , 85 % women , with pain intensity of the neck/shoulders 3.5 and of the low back 2.8 on a scale of 0 - 10 ) . A blinded assessor took measures at baseline and follow-up . Participants were r and omly assigned to training -- consisting of ballistic full-body kettlebell exercise 3 times per week for 8 weeks -- or a control group . The main outcome measures were pain intensity of the neck/shoulders and low back , isometric muscle strength , and aerobic fitness . RESULTS Compared with the control group , pain intensity of the neck/shoulders decreased 2.1 points [ 95 % confidence interval ( 95 % CI ) -3.7- -0.4 ] and pain intensity of the low back decreased 1.4 points ( 95 % CI -2.7- -0.02 ) in the training group . Compared with the control group , the training group increased muscle strength of the trunk extensors ( P<0.001 ) , but not of the trunk flexors and shoulders . Aerobic fitness remained unchanged . CONCLUSIONS Worksite intervention using kettlebell training  reduces pain in the neck/shoulders and low back and improves muscle strength of the low back among adults from occupations with a high prevalence of reported musculoskeletal pain symptoms . This type of training does not appear to improve aerobic fitness
