This study evaluates if the physiotherapy treatment based on eccentric exercise, ultrasound-guided PNE or a combination of both therapies on chronic soleous injuries may cause changes in pain, functionality, dorsal flexion of the foot, balance and muscle fatigue in dancers.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Eccentric group | Experimental | The dancers of this group wil perform a soleus eccentric exercise |
|
| PNE group | Experimental | The dancers of this group will receive a PNE treatment, consisting of the application of galvanic current, by ultrasound. The approach will be performed with a transverse axis with a needle orientation that will depend on the location of the target tissue. The parameters will be 3 mA, 3 seconds, 3 impacts (3: 3: 3). The periodicity will be 1day/7day/21day |
|
| Combined group | Experimental | The dancers of this group will receive a combined treatment and will be carried out in the same way as the other two groups. |

| Measure | Description | Time Frame |
|---|---|---|
| change of pain level | Visual Analogue Scale (VAS: 0=no pain; 100= pain as bad as can be | Change from Baseline VAS at 3 months months |
| Change of Lunge Test | This test measures the ankle range of motion. Less than 9/10 cm, range of motion will be considered restricted | Change from Baseline lunge test at 3 months months |
| Change of the Releve test | During the unilateral balance test with open eyes, the participant will be asked to hold as much time as possible in the relay position (raised heel of the floor) on one leg | Change from Baseline releve test at 3 months months |
| Change of the Endurance test | The unilateral raised heel test. The dancer should repeatedly lift the heel from the floor to the maximum range of plantar flexion movement as many times as possible. | Change from Baseline endurance test at 3 months months |
| Change of the Balance test | The test will be conducted with closed eyes, flat feet and barefoot participants and dancers will perform a retiré position. Participants will maintain the position as long as possible. | Change from Baseline balance test at 3 months months |
| Changes of the DFOS questionnaire | This questionnaire measures the pain and function (0= bad; 90=well) | Change from Baseline DFOS questionnaire at 3 months months |
| Change of the Minimal Detectable Change (MCD) |

The minimal detectable change is defined as a valid change in score that is not due to chance. Minimally clinically important difference (MCID), in comparison, goes beyond valid change to assess meaningful difference in dance function |
