Study summary

The goal of this observational study is to learn about rotator cuff patients. The main questions it aims to answer are:

  • What is the minimal clinically important difference value of the Shoulder Disability Questionnaire, the short version of the Western Ontario Rotator Cuff Index, the Shoulder Rating Questionnaire, and the University of California-Los Angeles Shoulder Scale?
  • What is the substantial clinical benefit value of the Shoulder Disability Questionnaire, the short version of the Western Ontario Rotator Cuff Index, the Shoulder Rating Questionnaire, and the University of California-Los Angeles Shoulder Scale?
  • What is the patient-acceptable symptomatic state value of the Shoulder Disability Questionnaire, the short version of the Western Ontario Rotator Cuff Index, the Shoulder Rating Questionnaire, and the University of California-Los Angeles Shoulder Scale?
  • What is the maximal outcome improvement value of the Shoulder Disability Questionnaire, the short version of the Western Ontario Rotator Cuff Index, the Shoulder Rating Questionnaire, and the University of California-Los Angeles Shoulder Scale?
  • What are the risk factors that prevent rotator cuff patients from reaching the minimal clinically important difference value?
  • What are the risk factors that prevent rotator cuff patients from reaching the substantial clinical benefit value?
  • What are the risk factors that prevent rotator cuff patients from reaching the patient-acceptable symptomatic state value?
  • What are the risk factors that prevent rotator cuff patients from reaching the maximal outcome improvement value?

What researchers measure

Primary outcomes

  1. Functional level

    Shoulder Disability Questionnaire (total score between 0-100) (higher values indicate higher disability)

    Time frame: before the treatment and within 1 week after 2 months of treatment

  2. Functional level

    The short version of the Western Ontario Rotator Cuff Index (total score between 0-100) (higher values indicate higher functional level)

    Time frame: before the treatment and within 1 week after 2 months of treatment

  3. Functional level

    Shoulder Rating Questionnaire (total score between 17-100) (higher values indicate higher functional level)

    Time frame: before the treatment and within 1 week after 2 months of treatment

  4. Functional level

    The University of California-Los Angeles Shoulder Scale (total score between 0-100) (higher values indicate higher functional level)

    Time frame: before the treatment and within 1 week after 2 months of treatment
