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 ) .
Effectiveness of an at-work exercise program in the prevention and management of neck and low back complaints in nursery school teachers.
The aim of the study was to determine the effectiveness of an extension-oriented exercise program in the prevention and management of low back/neck pain in nursery school teachers . A Cluster R and omized Controlled Trial was utilized . Seventy-one nursery school teachers working in nine school buildings were r and omly divided into two groups , with each school as a unit of r and omization . All the teachers in both groups received an ergonomic brochure ; teachers in the experimental group also received an extension-oriented exercise program , conducted by a physical therapist . Data were collected at baseline and at a two-month follow-up . The primary outcome measure recorded was the level of disability ( Rol and Morris Disability Question naire and Oswestry Disability Index ) , while secondary outcome measure included the evaluation of cervical and lumbar physical discomfort ( Visual Analogue Scale ) . At follow-up , a significant improvement was registered in the experimental group as compared to the control group for all the outcomes evaluated . In conclusion an extension-oriented exercise program may be a useful strategy to prevent low back and neck complaints and to reduce consequent LBP functional disability among nursery school teachers
