The aim of the randomized clinical trial is to investigate if "exercising into pain" gives better results in term of clinical outcomes compared to a non-painful exercise program.
Exercise therapy is the first choice of treatment in the treatment of subacromial shoulder pain (SSP). Guidelines suggest exercise therapy for at least three months and research underlines the importance of progressive loaded exercise therapy at high dosage. However, it is not clear which is the best type of exercise and if pain should be provoked or avoided during exercise. Recent research found that painful exercises are beneficial in short term on pain and function in patients with different kinds of chronic musculoskeletal pain. The aim is to investigate if one painful exercise can give better and faster results in the management of SSP than non-painful program.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| exercising into pain | Experimental | The participants will train during 12 with progressive loaded exercises, three times per week. There are 9 sessions of supervised physiotherapy treatment, lasting 30 minutes, while the rest of the sessions is conducted as home exercises. There are 4 strengthening exercises, including 2 in closed kinetic chain exercises and 2 executed with the elastic band or with dumbbell/weight. One exercise will be performed with pain ranging between 4 and 7 on a NPRS (Numeric Pain Rating Scale) and the rest of the exercises will be performed with no/slight pain, ranging between 0 and 2 on NPRS. At week 9, patients will continue to exercise with pain between 0 and 2 in all exercises. 10/15 minutes of manual therapy (posterior capsular release) will be applied during the physiotherapy session. |

| exercising with no/slight pain | Active Comparator | The participants will train during 12 weeks with progressive loaded exercises, three times per week. There are 9 sessions of supervised physiotherapy treatment, lasting 30 minutes, while the rest of the sessions is conducted as home exercises. There are 4 strengthening exercises, including 2 in closed kinetic chain exercises and 2 executed with the elastic band or with dumbbell/weight. All the exercises will be performed with no/slight pain, ranging between 0 and 2 on NPRS. 10/15 minutes of manual therapy (posterior capsular release) will be applied during the physiotherapy session. |

| exercising into pain | Other | the intervention consists in 4 strength exercises: one will be performed into pain (ranging between 4 and 7 on NPRS scale) and the rest between 0 adn 2 on a NPRS scale |
| Measure | Description | Time Frame |
|---|---|---|
| Shoulder Pain and Disability Index (SPADI) | There are 13 items, divided in two subscales: pain (5 items) and function (8 items). Each item is scored from 0 (no pain/no difficulty) to 10 (worst imaginable pain/so difficult it requires help) on a NPRS. The final score is a percentage derived from an average of the two subscales, where higher score means worse outcome. | Change from baseline to 12 weeks |

| Global perceived effect (GPE) | It is measured on a 7-Likert Scale, ranging from 1 (way much better) to 7 (way much worse); higher scores mean worst global perceived effect. | 12 weeks |
| Adherence | It is analysed in terms of attendance to the physiotherapist-led sessions and adherence to the home-exercise protocol. Good level of adherence is defined by: attendance of 7/9 (80%) of physiotherapist led-sessions and 22/27 (80%) days of home-exercises completed. |

| Visual Analogue Scale (VAS) | It measures pain during activity, during night, in the past 24 hours. It is measured on a scale from 0 to 100, where 0=no pain, 100=worst imaginable pain. | Change from baseline to 12 weeks |
