To evaluate the effect of job rotation on pain in wrist work related musculoskeletal disorders WMSDs
（ ）Methods
of physical therapists PTs . A total of 100 PTs from nine medical institutions were selected as the research subjects
，
using judgment sampling method and they were divided into control group and intervention group by stratified random sampling
，
method with 50 person in each group. The individuals in control group perform routine works. People in the intervention group
were rotated between posts or added mobile shift replacements in daily work for 30 minutes. The duration of intervention was
， ， （ ）
once a day five days a week for ten weeks. Visual Analogue Scale VAS score and pain duration were used as the evaluation
，
indexes of intervention effect. The changes of indexes before intervention five weeks and ten weeks after intervention were
Results ，
compared between the two groups. Before intervention there was no significant difference in the VAS score and pain
（ P ）
duration between the control group and the intervention group all >0.05 . There was no significant difference in VAS score
（ P ）
and pain duration among the control group at three time points after intervention all >0.05 . The VAS score of PTs in the
（P ），
intervention group at ten weeks was lower than that in the control group at the same time point <0.05 and it was lower than
（ P ）
that before intervention and at five weeks of intervention in the same group all <0.05 . The pain duration of PTs in the
（ P ），
intervention group was lower than that in the control group at five and ten weeks after intervention all <0.05 and was lower
（ P ） Conclusion ，
