There was strong evidence that duration away from work from both MSK or pain-related conditions and MH conditions were significantly reduced by multi-domain interventions encompassing at least two of the three domains .
There was moderate evidence that these multi-domain interventions had a positive impact on cost outcomes .
There was strong evidence that cognitive behavioural therapy interventions that do not also include workplace modifications or service coordination components are not effective in helping workers with MH conditions in RTW .
Evidence for the effectiveness of other single-domain interventions was mixed , with some studies reporting positive effects and others reporting no effects on lost time and work functioning .
Purpose The objective of this systematic review was to synthesize evidence on the effectiveness of workplace-based return-to-work ( RTW ) interventions and work disability management ( DM ) interventions that assist workers with musculoskeletal ( MSK ) and pain-related conditions and mental health ( MH ) conditions with RTW .
Management of occupational back pain: the Sherbrooke model. Results of a pilot and feasibility study.
OBJECTIVES --The aim was to combat occurrence of  chronic occupational back pain .  METHODS --A multidisciplinary model to manage back pain that includes both clinical and ergonomic approaches has been developed . Early detection , early clinical and ergonomic evaluations , and early active treatment make up the cornerstone of management . Detection of cases starts after four weeks of absence from work . An ergonomic intervention is implemented at six weeks . A medical specialist is involved at eight weeks . If return to work is not possible after 12 weeks , a functional recovery therapy followed by a therapeutic return to work is implemented . A multidisciplinary team decides if return to original or modified work is possible or if vocational rehabilitation is necessary . This model has been implemented by the investigators in the Sherbrooke ( Quebec , Canada ) area , and is presently being evaluated through a r and omised trial in 31 industrial settlements ( about 20,000 workers ) . A cluster r and omisation of industries and workers will allow separate testing of ergonomic and clinical interventions . RESULTS --One year after implementation , 31 of 35 of the eligible industrial sites participated in the study and 79 of 88 of the eligible workers affected by recent back pain had agreed to participate .  Ergonomic and clinical interventions  have been implemented as planned . Only three workers dropped out . Hence this global clinical and ergonomic management programme has been shown to be feasible in a general population . CONCLUSION --A global management programme of back pain joining ergonomic and clinical intervention with a multidisciplinary approach has not been tested yet . Linking these two strategies in a same multidisciplinary team represents a systemic approach to this multifactorial ailment . During the first year of this trial we did not find any conflict between these two interventions from the employer 's or worker 's point of view
