| Measure | Time frame |
|---|---|
| Shoulder Disability Questionnaire: a 16-item measure for functional status limitation in patients with shoulder disorders (Van der Heijden e.a., 2000). Study data will be collected at the following moments: at inclusion, at randomization and three, six and twelve months after randomization. | — |

| Measure | Time frame |
|---|---|
| 1. Constant-Murley score; 2. Shoulder Pain Score; 3. Shoulder Rating Questionnaire; 4. Patient-perceived recovery; 5. (Dutch) Short-form 36; 6. Cost-effectiveness. The Constant-Murley Score is a shoulder-specific scoring system in which patient-reported subjective assessment and objective measurement of shoulder function takes place (Constant e.a., 1987). The Shoulder Pain Score is a concise questionnaire for the assessment of pain experienced by patients with shoulder complaints (Winters e.a., 1996). The Shoulder Rating Questionnaire (SRQ-DLV) is a self-administered patient based instrument which assesses shoulder function in seven domains (Vermeulen e.a., 2005). Patient-perceived recovery is a one-item score concerning recovery following treatment measured on a seven-point ordinal scale. The (Dutch) Short-form 36 Health Survey is a Health-related Quality of Life Assessment system and is composed of 36 questions and standardized response choices, organized into eight multi-item scales (Aaronson, 1998). An economic evaluation will be performed using a questionnaire for assessment of direct health care costs as well as direct non-health related costs. These data will be used for a cost-effectiveness analysis. | — |
