For workers with persistent neck and shoulder pain , evidence supports mixed supervised and unsupervised high-intensity strength training or advice alone ( grade s I-III NAD ) .
A multimodal approach including manual therapy , self-management advice , and exercise is an effective treatment strategy for both recent-onset and persistent neck pain
OBJECTIVE The objective was to develop a clinical practice guideline on the management of neck pain-associated disorders ( NADs ) and whiplash-associated disorders ( WADs ) .
This guideline replaces 2 prior chiropractic guidelines on NADs and WADs .
Effectiveness of participatory training for prevention of musculoskeletal disorders: a randomized controlled trial
Purpose Health and safety training program has been applied to prevent work-related  musculoskeletal disorders ( MSDs ) in workplace . We evaluated the effectiveness of participatory training and didactic training programs on MSD prevention among frontline workers in Shenzhen , China . Methods The authors r and omly assigned 918 workers from intervention factories to receive participatory training ( intervention group ) , and 907 workers from intervention factories and 1,654 workers from control factories to receive didactic training ( control_1 group , control_2 group , respectively ) from June 1 , 2008 to November 30 , 2009 . Participants were asked to report experience of ache , pain or discomfort in 10 body parts at baseline and 1 year after training . Data were analyzed to compare the MSD prevalence 1 year before and 1 year after training in different groups from 2009 to 2010 . Results The follow-up rate was 61 % ( 2,120/3,479 ) at 1 year after training . In the year after training , there were no statistically significant changes in the proportion of workers who reported MSD in any body part . MSD prevalence rates in the intervention group reduced from 16.8 to 9.9 % for lower extremities ( χ2 = 13.102 , p < 0.001 ) and from 12.9 to 8.3 % ( χ2 = 9.433 , p = 0.002 ) for wrist and finger at 1 year after training . However , the rates did not change significantly for upper back , lower back , neck , shoulder and elbow in the intervention group and for all 10 body parts in two control groups . Conclusions Overall , the training programs did not seem to prevent the occurrence of MSD among frontline workers . However , participatory training might be effective to reduce MSD in the lower extremities and wrist and finger
