Adapted ASES is a self-administered participant reported outcome measure, divided into 2 sections: pain and function. Pain subscale is a single item, 11-point numeric rating scale, ranging from 0 (no pain at all) to 10 (worst pain), calculated as 10 - pain raw score and multiplying by 5, score ranging from 0 (worst pain) to 50 (no pain). Function subscale consists of 10 activities, 4-point ordinal scale about their ability to do the activity with the affected arm, ranging from 0 (unable to do) to 3 (not difficult), calculated by multiplying total score for 10 items by 5 and then dividing it by 3, score range of 0 (no function) to 50 (full function).

Adapted ASES composite score is the sum of the pain subscale score (50% of the composite score) and function subscale score (50% of the composite score), score range of 0 (worst pain) to 100 (least pain). Positive change from Baseline score means an improvement in pain and/or shoulder function.

The Patient-reported Global Severity of Adhesive Capsulitis is a single item, 11-point numerical rating scale that asks participants to rate the overall severity of their adhesive capsulitis symptoms on a scale from 0 (no severity) to 10 (severe as can be).

The Patient-reported Change in Severity of Adhesive Capsulitis is a questionnaire that asks participants if their adhesive capsulitis symptoms are "Better, About the Same, or Worse" since the last time the questionnaire was administered. Participants who reported that their symptoms are better or worse are then asked to rate the change in their symptoms on a 7-point ordinal scale for worse and better severity. An overall severity of worse was rated from 0 (almost the same, hardly worse at all) to -6 (a very great deal worse). An overall severity of better was rated from 0 (almost the same, hardly better at all) to 6 (a very great deal better).

Only participants with a response of 'Worse' or 'Better' were analyzed. Participants with an overall severity response of 'About the same' were excluded from the summary table below. For overall worse severity, a lower score indicated a worse outcome. For overall better severity, a higher score indicated a better outcome.

A responder was defined as a participant with a response of "very satisfied", "satisfied" or "somewhat satisfied" in the satisfaction with treatment.
