Objective To observe the clinical effect and safety of three kinds of external therapy for frozen shoulder.Methods Ninety cases of frozen shoulder were randomized into manipulation group

acupuncture group and Voltaren group

with 30 in each.The manipulation

acupuncture and Vlotaren were added to the three groups respectively for 14days besides normal function exercises.The symptoms and signs such as shoulder pain

activity pain

tenderness and shoulder flexibility were observed and scored before the treatment and on the 7th and 14th day of the treatment.The safety was observed as well.Results On the 7th day of the treatment

the effective rate of the manipulation group was significantly higher than that of the acupuncture group（P<0.01）

but the difference between the manipulation group and Voltaren group was not statistically significant（P>0.05）.On the 14th day of the treatment

the recovery rate and excellence rate of the manipulation group and Voltaren group were significantly higher than those of the acupuncture group（P<0.01）

but the difference between the manipulation group and Voltaren group was not statistically significant（P>0.05）.Comparing with other two groups

the total effective rate of the manipulation group was significantly higher（P<0.05）.The scores of main symptoms and signs were all significantly decreased on the 7th day and 14th day of the treatment in three groups（P<0.01）.On the 14th day of the treatment

the difference was statistically significant in should tenderness between the acupuncture group and manipulation group（P<0.05）

but there was no statistical significance between the manipulation group and Voltaren group（P>0.05）.There was no statistical significance in other index（P>0.05）.There was no adverse reaction in all groups.Conclusion The manipulation

acupuncture and Voltaren are safe for frozen shoulder.The effect of relieving shoulder tenderness of manipulation and Voltaren are superior to that of acupuncture.
