SPADI score
In the present study, we have used shoulder Pain and Dis- ability Questionnaire in order to document the level of dis- ability with frozen shoulder patient. This scale has been used in previous studies with various shoulder pathology.32, 33 The improvement noted in-group 1 was (14.99±9.03) and group 2 was (16.44±7.09) which was greater than the MCID of this scale. Here, both the group showed similar improvement. Tvieta et al26 had reported the responsiveness of SPADI scale in-patient with frozen shoulder. Point estimates (1.45) for be- tween group changes in disability not exceeded the reported MCIDs.
In addition, using MCID of 13 point for SPADI scale, NNT was calculated. The NNT (Number needed to treat) is 5. This means that 5 patients are required in order to say our inter- vention is effective.
