Overall , there was low quality evidence that showed no significant differences between WIs and no intervention for pain prevalence or severity .

Effects of software programs stimulating regular breaks and exercises on work-related neck and upper-limb disorders.
OBJECTIVES This study evaluated the effects on work-related neck and upper-limb disorders  among computer workers stimulated ( by a software program ) to take regular breaks and perform physical exercises . Possible effects on sick leave and productivity were studied as well . A r and omized controlled design was used with cluster r and omization . Altogether 268 computer workers with complaints in the neck or an upper limb from 22 office locations were r and omized into a control group , one intervention group stimulated to take extra breaks and one intervention group stimulated to perform exercises during the extra breaks during an 8-weekperiod . Question naires were administered before and after the intervention , and questions were generated by the software during the intervention period . Computer usage was recorded online . RESULTS The data on self-reported recovery suggested a favorable effect ; more subjects in the intervention groups than in the control group reported recovery ( 55 % versus 34 % ) from their complaints and fewer reported deterioration ( 4 % versus 20 % ) . However , a comparison between the reported pre- and postintervention scores on the severity and frequency of the complaints showed no significant differences in the change among the three groups . No effects on sick leave were observed . The subjects in the intervention groups showed higher productivity . CONCLUSIONS The use of a software program stimulating workers to take regular breaks contributes to perceived recovery from neck or upper-limb complaints . There seems to be no additional effects from performing physical exercises during these breaks
