Measuring clinically important change with the Patient-rated Tennis Elbow Evaluation

The Patient-rated Tennis Elbow Evaluation (PRTEE) enables quantitative rating by the patient of pain and functional impairment associated with tennis elbow or lateral elbow tendinopathy. When used as an outcome measure in trials of therapies, a minimum clinically important difference (MCID) value is required to interpret trial outcomes. This study aimed to calculate the MCID for a sample of patients diagnosed with lateral elbow tendinopathy (LET).
