Four participants were unable to physically attend the outpatient physical therapy department for reassessment: 1 at both 1- and 3-month follow-ups, 1 at the 3-month follow-up, and 2 at 3- and 6-month follow-ups. For these participants, data relating to their shoulder pain and functional impairment and self-rated change in symptoms were obtained via telephone. The SPADI has been found to be suitable for administration via telephone.46 Therefore, primary outcome measurement data were obtained for 98% (control group=96%, experimental group=100%), 95% (control group=96%, experimental group=94%), and 93% (control group=92%, experimental group=94%) of all participants at the 1-, 3-, and 6-month follow-ups, respectively. Reasons for participant withdrawal are detailed in Figure 1.
