Most common cause for shoulder pain and disability is frozen shoulder affecting approximately 2-4% of the general population. With the increase in age there is increase in the incidence of frozen shoulder with peak incidence of fifth and sixth decade and slightly female predominance. The aim of this study is to investigate the additional effect of physiotherapy after corticosteroid injections in first 2 stages of frozen shoulder.
Methods: This is randomised controlled trial. Painful frozen shoulder is the eligible criteria for this study. Patients were randomised into two group after obtaining patients consent. Ultrasound guided corticosteroid injection intra-articularly was given to both the groups. The physiotherapy group underwent physiotherapy whereas the other group did not. The shoulder pain and disability index were the primary outcome index. Range of motion and pain were the secondary outcome index. The patients were followed up after 6, 12, 26 weeks.
Result: A number of 30 patients were considered in this study in order to compare the relationship between CSI with and without physiotherapy out of which 16 patients were in the non-PT and 14 were in PT group. At baseline range of movements such as external rotation, abduction, anterior flexion was equally restricted in both the groups with mean range of 5.8 degree, 52.4 degree and 83.6 degree respectively. At the end of 26 weeks shoulder range of movements measurements were available for 90% of patients. No complications or adverse events were reported in both groups.
Conclusion: Physiotherapy along with corticosteroid injection improves ROM and functional movement restrictions in the early stage of frozen shoulder in the first 12 weeks when compared with corticosteroid alone.
